FOREWORD

In accordance with the NASA Space Act of 1958, the MSFC has provided for the

widest practicable and appropriate dissemination of information concerning its activities and

the results thereof.

Since July 1, 1960, when the George C. Marshall Space Flight Center was organized,

the reporting of scientific and engineering information has been considered a prime

responsibility of the Center. Our credo has been that "research and development work is

valuable, but only if its results can be communicated and made understandable to others."

The N number shown for the reports listed is assigned by the Center for AeroSpace

Information (CASI), Baltimore, Maryland, indicating that the material is unclassified and

unlimited and is available for public use. These publications can be purchased from the

National Technical Information Service, 5285 Port Royal Road, Springfield, Virginia 22161.

The N number should be cited when ordering.

TM-103555 October 1991

NASA Marshall Space Flight Center Solar

Observatory Report--January to June 1991.

J.E. Smith. Space Science Laboratory.

N92-14958

This report provides a description of the NASA

Marshall Space Flight Center's Solar Vector

Magnetograph Facility and gives a summary of its

observations and data reduction during January-June

1991. The systems that make up the facility are a

magnetograph telescope, an H-alpha telescope, a

Questar telescope, and a computer code.

Atmospheric Environment for Space Shuttle

(STS-37) Launch. G.L. Jasper and G.W. Batts.

Space Science Laboratory. N92-12375

This report presents a summary of selected

atmospheric conditions observed near space shuttle

STS-37 launch time on April 5, 1991, at Kennedy

Space Center, FL. Values of ambient pressure, temperature, moisture, ground winds, visual observations (cloud), and winds aloft are included. The

sequence of prelaunch Jimsphere-measured vertical

wind profiles is given in this report. The final

atmospheric tape, which consists of wind and thermodynamic parameters versus altitude, for STS-37

vehicle ascent has been constructed. The STS-37

ascent atmospheric data tape has been constructed

by Marshall Space Flight Center's Earth Science and

Applications Division to provide an internally consistent data set for use in postflight performance

assessments and represents the best estimate of the

launch environment to the 400,000-ft altitude that

was traversed by the STS-37 vehicle.

High-Frequency Data Observations From Space

Shuttle Main Engine Low-Pressure Fuel Turbopump Discharge Duct Flex Joint Tripod Failure

Investigation. T.F. Zoladz and R.A. Farr.

Structures and Dynamics Laboratory.

N92-13279

This report summarizes observations made by

MSFC Structures and Dynamics Laboratory

engineers during their participation in the space

shuttle main engine (SSME) low-pressure fuel

turbopump discharge duct flex joint tripod failure

investigation. New signal processing techniques

used by the Component Assessment Branch and the

Induced Environments Branch during the failure

investigation are described in detail. Moreover, nonlinear correlations between frequently encountered

anomalous frequencies found in SSME dynamic data

are discussed. Finally, the report concludes by

recommending the continuation of low-pressure fuel

(LPF) duct testing through laboratory flow simulations and MSFC-managed technology test bed

(TI_) SSME testing.

Characterization of the Effect of Boron Content

on Weld Cracking of Inconel 718 Type Alloys--

Center Director's Discretionary Fund Final

Report. R.G. Thompson, W.R. Gamwell, and

T.W. Malone. Materials and Processes Laboratory. X92-10214

Alloy 718 type compositions were studied to

characterize the effect of boron content on their weld

HAZ cracking. Alloy compositions studied were a

combined subset of specimens from General Electric

and University of Alabama at Birmingham studies.

Microcrack data were available for all specimens

used in this study. Differential thermal analyses,

Gieeble thermal analysis, scanning auger

microscopy, and microstructural evaluations were

performed on all alloy compositions to investigate

intergranular liquid formation and segregation

behavior effects of boron.

Four alloy 718 type compositions were cast

within the MSFC Materials and Processes Laboratory. Varestraint (weldability) testing was performed

in an attempt to quantify the effect of boron on their

hot cracking susceptibility.

Boron was found to increase microfissuring

behavior in alloy 718 type compositions by its

potency as a Laves former and by the resultant long

solidification range that Laves-forming alloys have.

It was found that carbon in large concentrations in

these type alloys can significantly alter their solidification behavior and completely reverse the effect of

a Laves former like boron.

The Effects of Multiple Repairs on lnconel 718

Weld Mechanical Properties. C.K. Russell,

A.C. Nunes, Jr., and D. Moore. Materials and

Processes Laboratory. N92-14380

Inconel 718 weldments were repaired 3, 6, 9,

and 13 times using the gas tungsten arc welding process. The welded panels were machined into

mechanical test specimens, postweld heat treated,

and nondestructively inspected. Tensile properties
NASA TECHNICAL MEMORANDUM

and high-cycle fatigue life were evaluated and the

results compared to unrepaired weld properties.

Mechanical property data were analyzed using the

statistical methods of difference in means for tensile

properties and difference in log means and Weibull

analysis for high-cycle fatigue properties.

Statistical analysis performed on the data did not

show a significant decrease in tensile or high-cycle

fatigue properties due to the repeated repairs, Some

degradation was observed in all properties; however,

it was minimal.

National Launch System Cycle 1 Loads and

Models Data Book. F. Bugg, J. Brunty,

G. Ernsberger, D. McGhee, L, Gagliano,

F. Harrington, D. Meyer, and E. Blades. Structures and Dynamics Laboratory. N92-30215

This document contains preliminary cycle 1

loads for the National Launch System NLS 1 and

NLS 2 vehicles. The loads provided and recommended as design loads represent the maximum

loads expected during prelaunch and flight regimes,

i.e., limit loads, except that propellant tank ullage

pressure has not been included. Ullage pressure

should be added to the loads book values for cases

where the addition results in higher loads. The loads

must be multiplied by the appropriate factors of

safety to determine the ultimate loads for which the

structure must be capable.

No-Vent Fill Pressurization Tests Using a

Cryogen Simulant. G.R. Schmidt, R.W.

Carrigan, J.E. Hahs, D.A. Vaughan, and D.C.

Foust. Propulsion Laboratory. N92-15354

This report describes the results of an experimental program which investigated the performance

of various no-vent fill techniques for tank-to-tank

liquid transfer. The tests were performed using a

cryogen simulant (Freon-114) and a test-bed consisting of a multiple tank/plumbing network that

enabled investigations of a variety of different inlet

flow and active mixing regimes. Several results and

conclusions were drawn from the 26 transfer experiments comprising the program. Most notable was

the significant improvement in fill performance (i.e.,

minimized fill time and maximized fill fraction) with

increased agitation of the liquid surface. Another

was the close correlation between measured condensation rates and those predicted by recent theories

which express condensation as a function of turbulent eddy effects on the liquid surface. In most cases,

test data exhibited strong agreement with an analytical model which accounts for tank heat transfer and

thermodynamics in a 1-g environment.

TM-103562 December 1991

Lunar Mission Aerobrake Performance Study.

J. Mulqueen and D. Coughlin. Program

Development Directorate and Systems Analysis

and Integration Laboratory. N92-15079

Nine lunar mission scenarios were developed to

show the transfer vehicle performance benefits of

aerobraking into low-Earth orbit (LEO) upon Earth

return as opposed to an all-propulsive maneuver.

The initial mass in LEO (IMLEO) of the lunar

transfer vehicle is considered the measure of vehicle

performance, Four types of mission profiles in conjunction with two vehicle concepts were used to

construct the scenarios. These nine scenarios were

designed to represent a broad range of possible lunar

missions so that a general knowledge base of aerobraking and lunar transfer vehicle performance

levels could be obtained. Also discussed in this

study are the mass sensitivities of each transfer

vehicle to changes in the selected design parameters:

ISP, crew module mass, payload to surface, and

aerobrake mass fraction.

A parametric study was performed on two of the

mission scenarios to help quantify the performance

benefits by adding a set of drop tanks to the vehicle.

The parametric study also provides partial derivatives which show the sensitivities of IMLEO to the

four design parameters listed above. The last section

of this report is a ranking of the mission scenarios

based on vehicle performance.

The intent of this report is to present vehicle

performance levels only. No consideration is given

to the Earth-to-orbit vehicle, cost, or operational

complexities such as rendezvous, aerobrake guidance, or contingencies.

Differential Thermal Analysis of Lunar Soil

Simulant. D. Tucker and A. Setzer. Materials

and Processes Laboratory. N92-15951

Differential thermal analysis of lunar soil simulant known as "Minnesota Lunar Simulant-l"

(MLS-1) was performed. The MLS-1 was tested in

the as-received form, in glass form, and with

additional silica. The silica addition was seen to

depress nucleation events which leads to a better

glass former.

Space Station Freedom Environmental Control

and Life Support System Phase III Water

Recovery Test Stages 1A, 2A, and 3A Final

Report. R.M. Bagdigian, D.L. Carter, D.W.

Holder, C.F. McGriff, M.C. Roman, M.S.

Traweek, and W.R. Williams. Structures and

Dynamics Laboratory. X92-10218

A series of tests has been conducted at the

NASA Marshall Space Flight Center (MSFC) to

evaluate the performance of a predevelopment water

recovery system. Potable, hygiene, and urine reclamation systems were integrated with end-use equipment items and successfully operated in open and

partially closed-loop modes, with man-in-the-loop,

for a total of 28 days. Several significant subsystem

physical anomalies were encountered during testing.

Reclaimed potable and hygiene water generally met

the current Space Station Freedom (S.S. Freedom)

water quality specifications for inorganic and microbiological constituents, but exceeded the maximum

allowable concentrations for total organic carbon

(TOC). This report summarizes the test objectives,

system design, test activities/protocols, significant

results/anomalies, and major lessons learned.

Single Wall Penetration Equations. K.B.

Hayashida and J.H. Robinson. Structures and

Dynamics Laboratory. N92-16682

This report compares five single plate penetration equations for accuracy and effectiveness. These

five equations are two well-known equations (FishSummers and Schmidt-Holsapple), two equations

developed for the Apollo project (Rockwell and

Johnson Space Center (JSC)), and one recently

revised from JSC (Cour-Palais). They were derived

from test results, with velocities ranging up to

8 km/s. Microsoft Excel software was used to construct a spreadsheet to calculate the diameters and

masses of projectiles for various velocities, varying

the material properties of both projectile and target

for the five single plate penetration equations. The

results were plotted on diameter versus velocity

graphs for ballistic and spallation limits using

Cricket Graph software, for velocities ranging from

2 to 15 km/s defined for the orbital debris. First,

these equations were compared to each other, then

each equation was compared with various aluminum

projectile densities. Finally, these equations were

compared with test results performed at JSC for the

Marshall Space Flight Center. These equations predicta wide range of projectile diameters at a given

velocity. Thus, it is very difficult to choose the

"right" prediction equation. The thickness of the

single plate could have a large variation by choosing

a different penetration equation. Even though all five

equations are empirically developed with various

materials, and especially for aluminum alloys, one

cannot be confident in the shield design with the

predictions obtained by the penetration equations

without verifying by tests.

Thermal Analysis Workbook. Edited by J.W.

Owen. Structures and Dynamics Laboratory.

N92-70379

This workbook is intended to allow the user to

gain a better understanding of thermal analysis,

problem-solving techniques, and interpretation of

results. Many simple and complex engineering

problems are presented and solved. These are solved

using state-of-the-art thermal analysis codes, closed

form solutions (which are used as "sanity checks"

for the codes), and many different numerical techniques with explanations of the methods and

assumptions used in solving the problems. Physical

phenomena which are considered include conduction, convection, radiation, change of phase, compressible and incompressible flow, N-dimensional

branching networks, conjugate thermal/hydraulic

analysis, Joule-Thompson heating, analysis of gas

mixture concentrations, venting, ablation, and

related subjects. Some codes discussed include

SINDA, TRASYS, ANSYS, PATRAN, and other

job specific codes.

SUNSPOT--A Program to Model the Behavior

of Hypervelocity Impact Damaged Multilayer

Insulation in the Sunspot Thermal Vacuum

Chamber of Marshall Space Flight Center. W.K.

Rule and K.B. Hayashida. Structures and

Dynamics Laboratory. N92-18383

This report describes the development of a computer program to predict the degradation of the insulating capabilities of the multilayer insulation (MLI)

blanket of Space Station Freedom due to a hypervelocity impact with a space debris particle. A finite

difference scheme is used for the calculations. The

computer program was written in Microsoft BASIC.

This report also describes a test program that was

undertaken to validate the numerical model. Twelve

MLI specimens were impacted at hypervelocities

with simulated debris particles using a light gas gun

at Marshall Space Flight Center. The impactdamaged MLI specimens were then tested for insulating capability in the space environment of the

Sunspot thermal vacuum chamber at MSFC. Two

undamaged MLI specimens were also tested for

comparison with the test results of the damaged

specimens. The numerical model was found to adequately predict the behavior of the MLI specimens in

the Sunspot chamber. A parameter, called diameter

ratio, was developed to relate the nominal MLI

impact damage to the apparent (for thermal analysis

purposes) impact damage based on the hypervelocity

impact conditions of a specimen.

High-Altitude Solar-Powered Platform. M.D.

Bailey and M.V. Bower. Structures and

Dynamics Laboratory. N92-21546

Solar power is a preeminent alternative to conventional aircraft propulsion. Previously, relatively

small solar-powered aircraft with limited usefulness

have flown for short durations. With continued

advances in solar ceils, fuel cells, and composite

materials technology, the solar-powered airplane is

no longer a simple curiosity constrained to flights of

several feet in altitude or minutes of duration.

A high-altitude solar-powered platform

(HASPP) has several potential missions, including

communications and agriculture. In remote areas, a

HASPP could be used as a communications link. In

large farming areas, a HASPP could perform remote

sensing of crops.

The impact of a HASPP in continuous flight for

1 year on an agriculture monitoring mission is presented. This mission provides farmers with near realtime data twice daily from an altitude which allows

excellent resolution on water conditions, crop

diseases, and insect infestation. Accurate, timely

data will enable farmers to increase their yield and

efficiency.

A design for a HASPP for the foregoing mission

is presented. In the design, power derived from solar

ceils covering the wings is used for propulsion,

avionics, and sensors. Excess power produced midday will be stored in fuel cells for use at night to

maintain altitude and course.

Microbial Biofilm Studies of the Environmental

Control and Life Support System Water

Recovery Test for Space Station Freedom. D.C.

Obenhuber, T.L. Huff, and E.B. Rodgers.

Materials and Processes Laboratory. N92-22283

NASA is developing a water recovery system

(WRS) for Space Station Freedom to reclaim human

waste water for reuse by astronauts as hygiene or

potable water. A water recovery test (WRT) currently in progress investigates the performance of a

prototype of the WRS. Analysis of biofilm accumulation, the potential for microbially influenced corrosion (MIC) in the WRT, and studies of iodine disinfection of biofilm are reported.

Analysis of WRT components indicated the

presence of organic deposits and biofilms in selected

tubing. Water samples for the WRT contained acidproducing and sulfate-reducing organisms implicated in corrosion processes. Corrosion of an

aluminum alloy was accelerated in the presence of

these water samples; however, stainless steel corrosion rates were not accelerated.

Biofilm iodine sensitivity tests using an experimental laboratory-scale recycled water system containing a microbial check valve (MCV) demonstrated that an iodine concentration of I to 2 mg/L

was ineffective in eliminating microbial biofilm. For

complete disinfection, an initial concentration of 16

mg/L was required which was gradually reduced by

the MCV over 4 to 8 hours to 1 to 2 mg/L. This

treatment may be useful in controlling biofilm

formation.

Porous silver, zinc, nickel, and cadmium electrodes

as well as silver/zinc cells were studied. State of

charge could be correlated with impedance data for

all but the nickel electrodes. State of health was correlated with impedance data for two silver/zinc cells,

one apparently good and the other dead. The experimental data were fit to equivalent circuit models.

Coupled Loads Analysis for Space Shuttle

Payloads. J. Eldridge. Structures and Dynamics

Laboratory. N92-24708

This report describes a method for determining

the transient response of, and the resultant loads in, a

system exposed to predicted external forces. In this

case, the system consists of four racks mounted on

the inside of a space station resource node module

(SSRNMO) which is mounted in the payload bay of

the space shuttle. The predicted external forces are

forcing functions which envelop worst case forces

applied to the shuttle during lift-off and landing.

This analysis, called a coupled loads analysis, is

used to; (a) couple the payload and shuttle models

together, (b) determine the transient response of the

system; and then (c) recover payload loads, payload

accelerations, and payload to shuttle interface forces.

Laboratory. N92 -28456

A pilot project in Taguchi methods was completed using actual electronic hardware. The primary

purpose was to familiarize engineers and managers

with the theory and mechanics of doing a Taguchi

experiment. The hardware selected was the National

Launch System (NLS) electromechanical actuator

(EMA) control electronics. This is a 25-kW motor

controller. Actual preparation and test time was 3 to

4 weeks. Results were quite good since the predicted

optimum set of component values also had the highest measured signal-to-noise ratio (S/N).

Assessment of a Head-Mounted Miniature

Monitor---Center Director's Discretionary Fund

Final Report (Project Number 89-07). J.P. Hale

II. Mission Operations Laboratory,. N92-30381

Two experiments were conducted to assess the

capabilities and limitations of the Private Eye, a

miniature, head-mounted monitor. The first experiment compared the Private Eye with a CRT and bard

copy in both a constrained and unconstrained work

envelope. The task was a simulated maintenance and

assembly task that required frequent reference to the

displayed information. A main effect of presentation

media indicated faster placement times using the

CRT as compared with hard copy. There were no

significant differences between the Private Eye and

either the CRT or hard copy for identification,

placement, or total task times. The goal of the

second experiment was to determine the effects of

various local visual parameters on the ability of the

user to accurately perceive the information of the

Private Eye. The task was an interactive video game.

No significant performance differences were found

under either bright or dark ambient illumination

environments nor with either visually simple or

complex task backgrounds. Glare reflected off of the

bezel surrounding the monitor did degrade performance. It was concluded that this head-mounted,

miniature monitor could serve a useful role for in

situ operations, especially in microgravity environments.

Anthropomorphic Teleoperation: Controlling

Remote Manipulators With the DataGlove--

Center Director's Discretionary Fund Final

Report (Project Number 89-06). J.P. Hale II.

Mission Operations Laboratory. N92-28521

A two-phase effort was conducted to assess the

capabilities and limitations of the DataGlove, a

lightweight glove input device that can output signals in real-time based on hand shape, orientation,

and movement. The first phase was a period for

system integration, checkout, and familiarization in a

virtual environmenL The second phase was a formal

experiment using the DataGlove as an input device

to control the protoflight manipulator arm

(PFMA)--a large telerobotic arm with an 8-ft reach.

The first phase was used to explore and understand

how the DataGlove functions in a virtual environment, build a virtual PFMA, and consider and select

a reasonable teleoperation control methodology.

Twelve volunteers (six males and six females) participated in a 2x3 (x 2) full-factorial formal experiment using the DataGlove to control the PFMA in a

simple retraction, slewing, and insertion task. Two

within-subjects variables, time delay (0, 1, and 2

seconds) and PFMA wrist flexibility (rigid/flexible),

were manipulated. Gender served as a blocking

variable. A main effect of time delay was found for

slewing and total task times. Correlations among

questionnaire responses, and between questionnaire

responses and session mean scores and gender, were

computed. The experimental data were also compared with data collected in another study that used a

six degree-of-freedom hand controller to control the

PFMA in the same task. It was concluded that the

DataGlove is a legitimate teleoperations input device

that provides a natural, intuitive user interface. From

an operational point of view, it compares favorably

with other "standard" telerobotic input devices and

should be considered in future trades in teleoperation

systems' designs.

A Generalized Reusable Guidance Algorithm for

Optimal Aerobraking. G.A. Dukeman. Systems

Analysis and Integration Laboratory. N92-28981

A practical real-time guidance algorithm has

been developed for guiding aerobraking vehicles in

such a way that the maximum heating rate, the

maximum structural loads, and the post-aeropass

delta-V requirement (for post-aeropass orbit insertion) are all minimized. The algorithm is general and

reusable in the sense that a minimum of assumptions

are made, thus minimizing the number of gains and

mission-dependent parameters that must be laboriously determined prior to a particular mission. A

particularly interesting feature is that inplane guidance performance is tuned by simply adjusting one

mission-dependent parameter, the bank margin;

similarly, the out-of-plane guidance performance is

tuned by simply adjusting a plane controller time

constant. Other objectives in the algorithm development are simplicity, efficiency, and ease of use. The

algorithm is developed for, but not necessarily

restricted to, a single pass mission and a trimmed

vehicle with bank angle modulation as the method of

trajectory control. Guidance performance is demonstrated via results obtained using this algorithm

integrated into an aerobraking test-bed program.

Comparisons are made with numerical results from a

version of the aerobraking guidance algorithm that

was to be flown onboard NASA's aeroassist flight

experiment (AFE) vehicle. Promising results are

obtained with a minimum of development effort.

Comparison of Epifluorescent Viable Bacterial

Count Methods. E.B. Rodgers and T.L. Huff.

Materials and Processes Laboratory. N92-30305

Two methods, the 2-(4-lodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT) method

and the direct viable count method (DVC), were

tested and compared for their efficacy for the

determination of the viability of bacterial populations. Use of the INT method results in the formation

of a dark spot within each respiring cell. The DVC

method results in elongation or swelling of growing

cells that are rendered incapable of cell division.

Although both methods are subjective and can result

in false positive results, the DVC method is best

suited to analysis of waters in which the number of

different types of organisms present in the sample is

assumed to be small, such as processed waters. The

advantages and disadvantages of each metllod are

discussed.

The development of pure phase 123 and Bibased 2223 superconductors has been optimized.

The preheat processing appears to be a very important parameter in achieving optimal physical properties. The synthesis of pure phases in the Bi-based

system involves effects due to oxygen partial pressure, time, and temperature. Orientation/melt-sintering effects include the extreme c-axis orientation of

Yttrium 123 and the Bismuth 2223, 2212, and 2201

phases. This orientation is conducive to increasing

critical currents. A procedure was established to

T.J. Chase. Propulsion Laboratory.

Extensive experimental investigation has been

carried out on used flight bearings of the phase II

high-pressure oxygen turbopump (HPOTP) of the

space shuttle main engine (SSME) in order to

determine the wear mechanisms, dominant wear

modes, and their extent and causes. The report

shows methodology, surface analysis techniques

used, results, and discussion. The mode largely

responsible for heavy bearing wear in lox has been

identified as adhesive/shear peeling of the upper

layers of bearing balls and rings. The mode relies on

the mechanisms of scale formation, breakdown, and

removal, all of which are greatly enhanced by the

heavy oxidation environment of the HPOTP. Major

causes of the high wear in bearings appear to be

lubrication and cooling, both inadequate for the

imposed conditions of operation. Numerous illustrations and evidence are given.

Specimens containing porosity and control specimens containing no porosity were tested. Results

indicate that for the weld configuration tested, the

This document describes scientific objectives

mission (TRMM) designed to acquire and investigate the distribution and variability of total lightning

on a global basis. The LIS is an EOS instrument,

whose lineage can be traced to a lightning mapper

sensor planned for flight on the GOES series of

operational meteorological satellites. The LIS is

conceptually a simple device, consisting of a staring

imager optimized to detect and locate lightning. The

LIS will detect and locate lightning with storm scale

resolution 0.e., 5 to I0 kin) over a large region of the

Earth' s surface along the orbital track of the satellite,

mark the time of occurrence of the lightning, and

measure the radiant energy. The LIS will have a

nearly uniform 90-percent detection efficiency

within the area viewed by the sensor, and will detect

intracloud and cloud-to-ground discharges during

day and night conditions. In addition, the LIS will

monitor individual storms and storm systems long

enough (i.e., 2 rain) to obtain a measure of the

lightning flashing rate in these storms when they are

within the field of view of the LIS. The LIS

attributes include low cost, low weight and power

(15 kg, 30 W), low data rate (6 kb/s), and important

science. The LIS will contribute to studies of the

hydrological cycle, general circulation and sea-surface temperature variations, investigations of the

electrical coupling of thunderstorms with the ionosphere and magnetosphere, and observations and

modeling of the global electric circuit. It will provide a global lightning climatology from which

changes, caused perhaps by subtle temperature

variations, will be readily detected.

Five scientists at MSFC/ESAD have EOS SCF

investigator status. Each SCF has unique tasks which

require the establishment of a computing facility

dedicated to accomplishing those tasks. An SCF

Working Group was established at ESAD with the

charter of defining the computing requirements of

the individual SCF's and recommending options for

meeting these requirements. The primary goal of the

working group was to determine which computing

needs can be satisfied using either shared resources

or separate but compatible resources, and which

needs require unique individual resources. The

requirements investigated included CPU-intensive

vector and scalar processing, visualization, data

storage, connectivity, and I/O peripherals. A review

of computer industry directions and a market survey

of computing hardware provided information regarding important industry standards and candidate computing platforms. It was determined that the total

SCF computing requirements might be most effectively met using a hierarchy consisting of shared and

individual resources. This hierarchy is composed of

five major system types: (1) a supercomputer class

vector processor, (2) a high-end scalar multiprocessor workstation, (3) a file server, (4) a few

medium- to high-end visualization workstations, and

(5) several low- to medium-range personal graphics

workstations. Specific recommendations for meeting

Low-velocity instrumented impact testing was

utilized to examine the effects of an outer lamina of

ultra-high molecular-weight polyethylene (Spectra)

on the damage tolerance of carbon/epoxy composites. Four types of 16-ply quasi-isotropic panels,

(0, +45, 90, -45)s2 were tested. Some panels contained no Spectra, while others had a lamina of

Spectra bonded to the top (impacted side), bottom,

or both surfaces of the composite plates. The specimens were impacted with energies up to 8.5 J.

Force-time plots and maximum force versus impact

energy graphs were generated for comparison purposes. Specimens were also subjected to cross-sectional analysis and compression-after-impact tests.

The results show that while the Spectra improved the

maximum load that the panels could withstand

before fiber breakage, the Spectra seemingly

reduced the residual strength of the composites.

N92-12052

Since Skylab, Marshall Space Flight Center

(MSFC) has recognized the need for large electrical

power systems (EPS's) in upcoming spacecraft. The

operation of the spacecraft depends on the EPS.

Therefore, it must be efficient, safe, and reliable. In

1978, as a consequence of having to supply a large

number of EPS personnel to monitor and control

Skylab, the Electrical Power Branch of MSFC began

the autonomously managed power system (AMPS)

project. This project resulted in the assembly of a

25-kW high-voltage dc test facility and provided the

means of getting man out of the loop as much as

possible. AMPS includes several embedded controllers which allow a significant level of

autonomous operation. More recently, the Electrical

Division at MSFC has developed the space station

module power management and distribution

(SSM/PMAD) breadboard to investigate managing

and distributing power in the Space Station Freedom

habitation and laboratory modules. Again, the

requirement for a high level of autonomy for efficient operation over the lifetime of the station and

for the benefits of enhanced safety has been

demonstrated. This paper describes the two breadboards and the hierarchical approach to automation

which was developed through these projects.

N92-11218

This paper describes the application of a weld

programming algorithm for vertical-up welding,

which is frequently desired for variable polarity

plasma arc welding (VPPAW). The Basic algorithm

performs three tasks simultaneously: control of the

robotic mechanism so that proper torch motion is

achieved while minimizing the sum-of-squares of

joint displacement; control of the torch while the

part is maintained in a desired orientation; and control of the wire feed mechanism location with

respect to the moving welding torch. This algorithm

has been presented and demonstrated in earlier

reports as applied to downhand welding, such as is

required for gas tungsten arc welding (GTAW).

This paper also presents a modification of this

algorithm which permits it to be used for vertical-up

welding. The details of this modification are discussed and simulation examples are provided for

illustration and verification.

Motor Slag. F.E. Roberts, III. Materials and

Processes Laboratory. N92-20949

Samples of alumina slag were investigated to aid

the Earth Science and Applications Division at

Marshall Space Flight Center (MSFC). Alumina

from space motor propellant exhaust and space

motor propellant slag was examined as a component

of space refuse. Thermal emittance and solar

absorptivity measurements were taken to support

their comparison with reflectance measurements

derived from actual debris. To determine the similarity between the samples, and space motor exhaust

or space motor slag, emittance and absorbance

results were correlated with an examination of

specimen morphology.

A NonlinearEstimatorfor Reconstructingthe

AngularVelocityof a SpacecraftWithoutRate

Gyros.M.E. PolitesandW.D.Lightsey.StructuresandDynamicsLaboratory. N92-13343

Thispaperpresentsanewschemefor estimating

the angularvelocity of a spacecraft without rate

gyros. It is based upon a nonlinear estimator whose

inputs are measured inertial vectors and their calculated time-derivatives relative to vehicle axes. It

works for all spacecraft attitudes and requires no

knowledge of attitude. It can use measurements from

a variety of onboard sensors like Sun sensors, star

trackers, or magnetometers, and in concert. It can

also use look angle measurements from onboard

tracking antennas for tracking and data relay satellites or global positioning system satellites. In this

paper, it is applied to a Sun point scheme on the

Hubble space telescope assuming all or most of its

onboard rate gyros have failed. Simulation results

are presented which verify it.

A Statistical Comparison of Two Carbon

Fiber/Epoxy Fabrication Techniques. A.J.

Hodge. Materials and Processes Laboratory.

N92-20950

A statistical comparison of the compression

strengths of specimens that were fabricated by either

a platen press or an autoclave were performed on

IM6/3501-6 carbon/epoxy composites of 16-ply

(0,+45,90,--45)s2 lay-up configuration. The samples

were cured with the same parameters and processing

materials. It was found that the autoclaved panels

were thicker than the platen press-cured samples.

Two hundred samples of each type of cure process

were compression tested. The autoclaved samples

had an average strength of 450 MPa (65.5 ksi), while

the press-cured samples had an average strength of

370 MPa (54.0 ksi). A Weibull analysis of the data

showed that there is only a 30-percent probability

that the two types of cure systems yield specimens

that can be considered from the same family.

Limit Cycle Vibrations in Turbomachinery. S.G.

Ryan. Structures and Dynamics Laboratory.

N92-14108

High-performance turbomachinery is susceptible

to a wide variety of vibration problems. Some of

these problems are rotor unbalance vibration,

dynamic instability, and subharmonic response to

unbalance excitation. Understanding these problems

is complicated when nonlinearities are present, as

they almost always are in actual hardware. For

example, dynamic instabilities may manifest themselves as limit cycle vibrations. In some cases, the

vibration levels are so high that the distinction

between a divergent instability and a limit cycle is

meaningless, This is because the machinery would

be destroyed in either case. In other cases, the limit

cycle may appear at relatively small levels. These

cases may appear to be benign; however, the

presence of the limit cycle may be an indication of

an impending divergent instability. This matter is

complicated by the fact that the frequency of the

limit cycle instability is frequently near one-half of

the unbalance excitation synchronous frequency.

This makes it difficult to distinguish between the

limit cycle and a subharmonic response.

The focus of this work is an examination of

rotordynamic systems which are simultaneously susceptible to limit cycle instability and subharmonic

response. Characteristics of each phenomenon are

determined as well as their interrelationship. A

normalized, single mass rotor model is examined as

well as a complex model of the high-pressure fuel

turbopump (HPFTP) of the space shuttle main

engine (SSME). Entrainment of limit cycle instability by subharmonic response is demonstrated for

both models. The nonuniqueness of the solution is

also demonstrated.

Structural Deterministic Safety Factors Selection

Criteria and Verification. V. Verderaime.

Structures and Dynamics Laboratory.

N92-19355

Though current deterministic safety factors are

arbitrarily and unaccountably specified, its ratio is

rooted in resistive and applied stress probability distributions. This study approached the deterministic

method from a probabilistic concept leading to a

more systematic and coherent philosophy and criterion for designing more uniform and reliable highperformance structures. The deterministic method

was noted to consist of three safety factors--a standard deviation multiplier of the applied stress distribution, a K-factor for the A- or B-basis material

ultimate stress, and the conventional safety factor to

ensure that the applied stress does not operate in the

inelastic zone of metallic materials. The conventional safety factor is specifically defined as the ratio

15
NASATECHNICALPAPERS

of ultimate to yield stresses. A deterministic safety

index of the combined safety factors was derived

from which the corresponding reliability proved the

deterministic method is not reliability sensitive.

Bases for selecting safety factors are presented, and

verification requirements are discussed. The suggested deterministic approach is applicable to all

NASA, DOD, and commercial high-performance

structures under static stresses.

The Role of Failure/Problems in Engineering: A

Commentary on Failures Experienced--Lessons

Learned. R.S. Ryan. Structures and Dynamics

Laboratory. N92-22235

This report presents the written version of a

series of seminars given to several aerospace companies and three National Aeronautics and Space

Administration (NASA) Centers. The results are

lessons learned through a study of the problems

experienced in 35 years of engineering. The basic

conclusion is that the primary cause of problems has

not been missing technologies, as important as technology is, but the neglect of basic principles.

Undergirding this is the lack of a systems focus from

determining requirements through design, verification, and operations phases. Many of the concepts

discussed are fundamental to total quality management (TQM) and can be used to augment this

product enhancement philosophy. Fourteen principles are addressed in this report with problems

experienced used as examples. Included is a discussion of the implication of constraints, poorly defined

requirements, and schedules. Design guidelines,

lessons learned, and future tasks are listed. Two

additional sections are included that deal with personal lessons learned and thoughts on future thrusts

(TQM). A separate report, to be published later, will

contain synopses of tile problems experienced. They

will be documented by project and cause,

Approximately 175 problems have been treated to

date.

Time-Frequency Representation of a Highly

Nonstationary Signal Via the Modified Wigner

Distribution. T.F. Zoladz, J.H. Jones, and

J. Jong. Structures and Dynamics Laboratory.

N92-20492

This report presents a new signal analysis technique called the modified Wigner distribution

(MWD). The MWD has been developed for the

Structures and Dynamics Laboratory at MSFC by

Dr. Jen-Yi Jong of Wyle Laboratories. The new signal processing tool has proven very successful in

determining time-frequency representations of

highly nonstationary multicomponent signals in both

simulation and trials involving actual space shuttle

main engine high-frequency data. The MWD departs

from the classic Wigner distribution (WD) in that it

effectively eliminates the cross coupling among

positive frequency components in a multiple component signal. This attribute of the MWD, which prevents the generation of "phantom" spectral peaks,

will undoubtedly increase the utility of the WD for

real-world signal analysis applications which more

often than not involve multicomponent signals.

The Effect of Acceleration Versus Displacement

Methods on Steady-State Boundary Forces. D.S.

McGhee. Structures and Dynamics Laboratory.

N92-21457

When a substructure model is reduced by the

Craig-Bampton method, a number of degrees-offreedom (DOF's) are retained as physical DOF's to

provide interface to other substructures. When more

DOF's are retained in this interface than are actually

required, the model is said to be over constrained.

The result of this, when using the displacement

method, is typically an inaccurate distribution of

boundary forces. This inaccuracy also occurs when

there are justifiably many interface DOF's which

result in an indeterminate interface. When the acceleration method is used, this inaccuracy is overcome.

However, many people do not fully understand this

method and the many ways of implementing it, and

so its implementation is sometimes haphazard.

This study describes the acceleration and displacement methods for use in the recovery of

coupled system boundary forces. A simple 2-DOF

system has been used for illustration. The effect of

the choice of method for use with indeterminate or

over-constrained boundaries has been investigated. It

has specifically looked at results from a simple twodimensional beam problem using both methods.

In the space shuttle payload community, there

has been an increase in the use of over-constrained

payload models. This has been, mainly, to afford

easy recovery of relative deflection data between the

payload and the shuttle, While there has also been an

increase in the use of the acceleration method for the

recovery of payload displacements and forces, the

displacement method remains the method used for

recovering system displacements and forces. Much

workhasbeendone on the effects of Craig-Bampton

modal truncation on system displacements and

forces; however, little work has been done on system

modal truncation (i.e., modes across the boundary).

The findings of this study indicate the effect of this

system level truncation is significant. This may be

particularly true for the 35-Hz system cutoff frequency that is required by the space shuttle. From

this study's findings, recommendations for areas of

study with space shuttle payload systems are made.

Technique to Eliminate Computational

Instability in Multibody Simulations Employing

the Lagrange Multiplier. G. Watts. Structures

and Dynamics Laboratory. N92-23436

This paper presents a programming technique to

eliminate computational instability in multibody

simulations that use the Lagrange multiplier. The

computational instability occurs when the attached

bodies drift apart and violate the constraints. The

programming technique uses the constraint equation,

instead of integration, to determine the coordinates

that are not independent. Although the equations of

motion are unchanged, a complete derivation of the

incorporation of the Lagrange multiplier into the

equation of motion for two bodies is presented. A

listing of a digital computer program which uses the

programming technique to eliminate computational

instability is also presented. The computer program

simulates a solid rocket booster and parachute connected by a frictionless swivel.

Effect of Type of Load on Stress Analysis of

Aggarwal. Structures and Dynamics Laboratory.

N92-26669

The standard procedure for qualifying the design

of duct (pipe) systems in the space shuttle main

engine (SSME) has been fairly well defined.

However, since pipe elbows are quite common and

important in the SSME duct systems, a clear understanding of the detailed stress profile of the components is necessary for accurate structural and life

assessments. This study was initiated to predict the

stress profile at/near the tangent point along the

cross section of the duct under various types of

loads. Also, this study was further extended to

understand the stiffening effect on stresses due to

pressure at the tangent point. The intention of this

study was to identify the importance of selecting

proper locations for mounting strain gauges and to

utilize the obtained results to anchor dynamic

models for accurate structural and life assessments

of the SSME ducts under dynamic environment. The

finite element method was utilized in this study.

This paper describes an experiment designed to

test the feasibility of using rotating unbalanced-mass

gimbaled payloads, while expending very little

power. The experiment is configured for groundbased testing, but the scan concept is applicable to

ground-based, balloon-borne, and space-based payloads, as well as free-flying spacecraft. In this paper,

the servos used in scanning are defined, the electronic hardware is specified, and a computer simulation model of the system is described. Simulation

results are presented that predict system performance

and verify the servo designs.

Gibbs Free Energy of Reactions Involving Si-C,

Materials and Processes Laboratory. N92-31278

Silicon carbide (Si-C) and silicon nitride

(Si3-N4) are considered for application as structural

materials and coating in advanced propulsion systems including nuclear thermal. Three-dimensional

Gibbs free energy surfaces were constructed for

reactions involving these materials in H2 and

H2/H2-O. Free energy plots are functions of temperature and pressure. Calculations used the definition of Gibbs free energy where the spontaneity of

reactions is calculated as a function of temperature

and pressure.

Silicon carbide decomposes to Si and CH4 in

pure H 2 and forms a Si-O 2 scale in a wet

atmosphere. Silicon nitride remains stable under all

conditions. There was no apparent difference in

reaction thermodynamics between ideal and Van tier

Waals treatment of gaseous species.

Spacecraft Flight Control System Design

Selection Process for a Geostationary

Communication Satellite. C. Barret. Structures

The Earth's first artificial satellite, Sputnik I,

slowly tumbled in orbit. The first U.S. satellite,

Explorer I, also tumbled out of control. Now, as we

launch the Mars observer and the Cassini spacecraft,

stability and control have become a higher priority.

This paper reviews the flight control system design

selection process using as an example a geostationary communication satellite which is to have a life

expectancy from 10 to 14 years.

Disturbance torques including aerodynamic,

magnetic, gravity gradient, solar, micrometeorite,

debris, collision, and internal torques are assessed to

quantify the disturbance environment so that the

required compensating torques can be determined.

Then control torque options including passive versus

active, momentum control, bias momentum, spin

stabilization, dual spin, gravity gradient, magnetic,

reaction wheels, control moment gyros, nutation

dampers, inertia augmentation techniques, three-axis

control, reaction control system (RCS), and RCS

sizing are considered. A flight control system design

is then selected, and preliminary stability criteria met

by the control gains selection.

A preloading device was used to examine the

effects of compressive prestress on the compressionafter-impact (CAI) strength of !6-ply, quasiisotropic carbon epoxy test coupons. T300/934

material was evaluated at preloads from 200 to 4,000

lb at impact energies from 1 to 9 joules. IM7/8551-7

material was evaluated at preloads from 4,000 to

10,000 lb at impact energies from 4 to 16 joules.

Advanced design of experiments methodology was

used to design and evaluate the test matrices. The

results showed that no statistically significant change

in CAI strength could be attributed to the amount of

compressive preload-.applied to the specimen.
