Eddy Current Inspection of Graphite Fiber

Components. Dr. G.L. Workman and C.C.

Bryson. Materials and Processes Laboratory. N91-10294

The recognition of defects in materials

properties still presents a number of problems

for nondestructive testing in aerospace systems.

This project attempts to utilize current capabilities in eddy current instrumentation, artificial

intelligence, and robotics in order to provide

insight into defining geometrical aspects of flaws

in composite materials which are capable of

being evaluated using eddy current inspection

techniques. The unique capabilities of E-probes

and horseshoe probes for inspecting probes for

inspecting graphite fiber materials have been

evaluated and appear to hold great promise once

the technology development matures.

This preliminary phase report describes the

initial results of modeling eddy current interactions with certain flaws in graphite fiber

samples.

Test and Model Correlation of the

Atmospheric Emission Photometric Imager

Fiberglass Pedestal. H.M. Lee III and L.A.

Barker. Structures and Dynamics Laboratory. N91-13766

This report presents the correlation of the

static loads testing and finite element modeling

for the fiberglass pedestal used on the

Atmospheric Emission Photometric Imaging

(AEPI) experiment. This payload is to be

launched in the space shuttle as part of the

ATLAS-1 experiment. Strain gauge data from

rosettes around the highly loaded base are

compared to the same load case run for the

Spacelab 1 testing done in 1981. Correlation of

the model and test data was accomplished

through comparison of the composite stress

invariant utilizing the expected flight loads for

the ATLAS-1 mission. Where appropriate, the

Tsai-Wu failure criteria was utilized in the

development of the key margins of safety.

Margins of safety are all positive for the pedestal

and are reported,

Coaligned Observations of Solar Magnetic

Fields at Different Heights—MSFC Center

Director's Discretionary Fund Final Report

(Project Number 88-10). MJ. Hagyard, E.A.

West, G.A. Gary, and J.E. Smith, Space

Science Laboratory. N91-10832

This document constitutes the final report for

MSFC Center Director's Discretionary Fund

Project Number 88-10. The objective of this

program was to develop the capability for obtaining cotemporal and coaligned observations of the

structure and evolution of the Sun's magnetic

field at two different heights in the solar

atmosphere: the photosphere, which is the

lowest region observable with optical telescopes, and the chromosphere, which lies just

above the photosphere and is a region where the

magnetic field dominates the gas motions so that

a well-ordered structure governed by the field is

observed. By obtaining this three-dimensional

picture of the solar magnetic field, we can

develop a better understanding of the magnetic

forces that produce and control the dynamic,

high-energy phenomena occurring in the solar

atmosphere that can affect the entire heliosphere, including our own terrestrial environment.

An Improved Exploratory Search Technique

for Pure Integer Linear Programming

Problems. F.R. Fogle. Systems Analysis and

Integration Laboratory. N91-13910

This report documents the development of a

heuristic procedure for the solution of pure

integer linear programming problems. The procedure draws its methodology from the ideas of the

Hooke and Jeeves type I and type II exploratory

searches, greedy procedures, and neighborhood

searches. It utilizes an efficient rounding procedure to obtain its first feasible integer point

from the optimal continuous solution obtained via

the simplex method.

Since this procedure is based entirely on

simple addition or subtraction of one to each

variable of a point in n-space and the subsequent

comparison of candidate solutions to a given set

of constraints, it facilitates significant complexity

improvements over existing techniques. It also

obtains the same optimal solution found by the

branch-and-bound technique in 44 out of 45

small to moderate size test problems. Two

example problems are worked in detail to

show the inner workings of the procedure.
NASA TECHNICAL MEMORANDUM

Furthermore, using an established weighted

scheme for comparing computational effort

involved in an algorithm, a comparison of this

algorithm is made to the more established and

rigorous branch-and-bound method. A computer

implementation of the procedure, in PCcompatible Pascal, is also presented and

discussed. This procedure for finding optimal

solutions to integer-type problems may be

applied to various systems engineering

situations in the conceptual, preliminary, and

detail design phases of the system development

cycle.

Dendritic Morphology and Microsegregation

in Directionally Solidified Superalloy, PWA1480, Single Crystal: Effect of GravityCenter Director's Discretionary Fund Report.

S.N. Tewari, M.V. Kumar, I.E. Lee, and P.A.

Curreri. Materials and Processes Laboratory. N91-15391

Primary dendrite spacings, secondary dendrite spacings, and microsegregation have been

examined in PWA-1480 single crystal specimens which were directionally solidified during

parabolic maneuvers on the KC-135 aircraft.

Experimentally observed growth rate and

thermal gradient dependence of primary dendrite

spacings are in good agreement with predictions

from dendrite growth models for binary alloys.

Secondary dendrite coarsening kinetics show a

reasonable fit with the predictions from an

analytical model proposed by Kirkwood for a

binary alloy. The partition coefficients of

tantalum, titanium, and aluminum are observed

to be less than unity; while that for tungsten and

cobalt are greater than unity. This is qualitatively

similar to their nickel base binaries. Microsegregation profiles experimentally observed for

PWA-1480 superalloy show a good fit with

Bower, Brody, and Flemings models developed

for binary alloys. Transitions in gravity levels do

not appear to affect primary dendrite spacings. A

trend of decreased secondary arm spacings with

transition from high gravity to the low gravity

period was observed at a growth speed of 0.023

cm s~l. However, definite conclusions can only

be drawn by experiments at lower growth

speeds which make it possible to examine the

side-branch coarsening kinetics over a longer

duration. Such experiments, not possible due to

the insufficient low-gravity time of the KC-135,

may be carried out in the low-gravity

environment of space.

Engineering Design Based on Risk—An

Alternate Criterion to the Engineering Safety

Factor. D.R. Moore. Materials and Processes Laboratory. X91 -10073

The design of engineering structures can be

based on risk when enough information about the

structure is available. This report compares

designing by risk to the more commonly used

approach of designing by an engineering factor of

safety. The safety factor concept of providing

structural assurance is challenged within this

report. New methods are developed to assist in

determining structural risk in an engineering

design when the design is based on the interference of two normally distributed engineering

phenomena. The risk factor (Rp) approach is

offered as an alternate method of establishing

engineering design criteria. The engineering risk

equation is developed which allows a simple

determination of risk when coefficients of variation are known. Several curves were developed

that relate Rp to coefficients of variation for

various reliabilities. The author concluded that

designs and redesigns should be based on risk

whenever possible.

Predicting Thunderstorm Evolution Using

Ground-Based Lightning Detection Networks. Steven J. Goodman. Space Science

Laboratory. N91-15660

Lightning measurements acquired principally

by a ground-based network of magnetic direction

finders are used to diagnose and predict the

existence, temporal evolution, and decay of

thunderstorms over a wide range of space and

time scales extending over four orders of

magnitude. The nonlinear growth and decay of

thunderstorms and their accompanying cloud-toground lightning activity is described by the three

parameter logistic growth model. The growth

rate is shown to be a function of the storm size

and duration, and the limiting value of the total

lightning activity is related to the available

energy in the environment. A new technique is

described for removing systematic bearing errors

from direction finder data where radar echoes are

used to constrain site error correction and

optimization (best point estimate) algorithms. A

nearest neighbor pattern recognition algorithm is

employed to cluster the discrete lightning discharges into storm cells, and the advantages and

limitations of different clustering strategies for

storm identification and tracking are examined.

The Rotating Spectrometer: New Biotechnology for Cell Separations. David A. Noever

and Helen C. Matsos. Space Science Laboratory. N91-15673

An instrument for biochemical studies, called

the rotating spectrometer, separates previously

inseparable cell cultures. The rotating spectrometer is intended for use in pharmacological

studies which require fractional splitting of

heterogeneous cell cultures based on cell morphology and swimming behavior. As a method to

separate and concentrate cells in free solution,

the rotating method requires active organism

participation and can effectively split the large

class of organisms known to form spontaneous

patterns. Examples include the biochemical

"star," an organism called Tetrahymena

pyriformis. Following focusing in a rotated frame,

the separation is accomplished using different

radial dependencies of concentrated algal and

protozoan species. The focusing itself appears as

concentric rings and arises from the coupling

between swimming direction and Coriolis forces.

A dense cut is taken at varying radii and

extraction is replenished at an inlet. Unlike

standard separation and concentrating techniques such as filtration or centrifugation, the

instrument is able to separate motile from

immotile fractions. For a single pass, typical split

efficiencies can reach 200 to 300 percent compared to the inlet concentration.

TM-103523 November 1990

A Biosensor for Cadmium Based on Bioconvective Patterns. David A. Noever and

Helen C. Matsos. Space Science Laboratory.

N91-15674

r

An in vitro method for monitoring cadmium,

one of the most lethal bivalent heavy metals, can

detect biologically active levels. The effects of

cadmium tend to concentrate in protozoa far

above natural levels and therein begin transferring through freshwater food chains to animals

and humans. In a small sample volume (~5 ml)

the method uses the toxic response to the protozoa, Tetrahymena pyriformis, to cadmium. The

assay relies on macroscopic bioconvective

patterns to measure the toxic response, giving a

sensitivity better than 1 u.g/1 and a toxicity

threshold to 7 ug/1 for Cd+2. Cadmium hinders

pattern formation in a dose-dependent manner.

Arrested organism growth arises from slowed

division and mutation to nondividing classes.

Unlike previous efforts, this method can be performed in a shallow flow device and does not

require electronic or chemical analyses to

monitor toxicity.

An Evaluation of Bearings Operating in a

Cryogenic Environment With Silicon Nitride

Rolling Elements, H.G. Gibson. Materials

and Processes Laboratory. N91 -18436

The bearings used in the space shuttle main

engine (SSME) high pressure oxidizer turbopump (HPOTP) do not meet the expected life

goals that were set for them. In an effort to

improve their performance, many solutions are

being studied. New bearing materials are being

developed, better manufacturing techniques are

being investigated, and improved cage materials

for better lubrication are being tested. This report

focuses on the replacement of steel balls with
NASA TECHNICAL MEMORANDUM

ones made of silicon nitride in 57-mm HPOTP

bearings. The bearings were then installed in a

test rig and run at near turbopump operating

conditions. The results from this test series have

been encouraging, with silicon nitride showing

good wear resistance and thermal stability.

TM-103525 November 1990

Atmospheric Environment for Space Shuttle

(STS-41) Launch. G.L. Jasper and G.W.

Batts. Space Science Laboratory.

N91-19529

This report presents a summary of selected

atmospheric conditions observed near space

shuttle STS-41 launch time on October 6, 1990,

at Kennedy Space Center, Florida. 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-41 vehicle

ascent has been constructed. The STS-41 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-41 vehicle.

A Damage Tolerance Comparison of

IM7/8551 and IM8G/8553 Carbon/Epoxy

Composites. D.G. Lance and A.T. Nettles.

Materials and Processes Laboratory.

N91-18222

A damage tolerance study of two new

toughened carbon fiber/epoxy resin systems was

undertaken as a continuation of ongoing work

into screening new opposites for resistance to

foreign object impact. This report is intended to

be a supplement to NASA TP 3029 in which four

new fiber/resin systems were tested for damage

tolerance. Instrumented drop weight impact

testing was used to inflict damage to 16-ply

quasi-isotropic specimens. Instrumented output

data and cross-sectional examination of the

damage zone were utilized to quantify the

damage. It was found that the two fiber/resin

systems tested in this study were much more

impact resistant than an untoughened composite

such as T300/934, but were not as impact resistant as other materials previously studied.

TM-103527 March 1991

Evaluation of Bearing Configurations Using

the Single Bearing Tester in Liquid Nitrogen.

T. Jett, P. Hall, and R. Thorn. Materials and

Processes Laboratory. N91-21532

Various bearing configurations were tested

using the Marshall Space Flight Center single

bearing tester with LN2 as the cryogenic coolant.

The baseline was one Rocketdyne phase I high

pressure oxidizer turbopump (HPOTP) pump end

45-mm bore bearing. The bearing configurations

that were tested included a Salox/M cage configuration, a silicon nitride ball configuration, an

elongated cage configuration, and a Bray 601

grease configuration.

GEOSIM—A Numerical Model for Geophysical Fluid Flow Simulation. Karen A.

Butler, Timothy L. Miller, and Huei-Iin Lu.

Space Science Laboratory. N91-21450

A numerical model which simulates geophysical fluid flow in a wide range of problems is

described in detail, and comparisons of some of

the model's results are made with previous

experimental and numerical studies. The model

is based upon the Boussinesq Navier-Stokes

equations in spherical coordinates, which can be

reduced to a cylindrical system when latitudinal

walls are used near the pole and the ratio of

latitudinal length to the radius of the sphere is

small. The equations are approximated by finite

differences in the meridional plane and spectral

decomposition in the azimuthal direction. The

An Evaluation of GTAW-P Versus GTA

Welding of Alloy 718. W.R. Gamwell, C.

Kurgan, and T.W. Malone. Materials and

Processes Laboratory. N91-21287

Mechanical properties have been evaluated

to determine statistically whether the pulsed

current gas tungsten arc welding (GTAW-P)

process produces welds in alloy 718 with room

temperature structural performance equivalent to

current space shuttle main engine (SSME)

welds manufactured by the constant current gas

tungsten arc welding (GTAW) process.

Evaluations were conducted on two base metal

lots, two filler metal lots, two heat input levels,

and two welding processes. The material form

was 0.125-inch (3.175-mm) alloy 718 sheet.

Prior to welding, sheets were heat treated to

either the ST or STA-1 condition. After welding,

panels were left as welded or heat treated to the

STA-1 condition, and weld beads were left intact

or machined flush. Statistical analyses were

performed on yield strength (YS), ultimate tensile strength (UTS), and high cycle fatigue

(HCF) properties for all the post welded

material conditions. Analyses of variance

(ANOVA) were performed on the data to

determine if there were any significant effects on

UTS or HCF life due to variations in base metal,

filler metal, heat input level, or welding process.

Statistical analyses have shown that the

GTAW-P process does produce welds with

room temperature structural performance

equivalent to current SSME welds manufactured

by the GTAW process, regardless of prior

material condition or post welding condition.

Parametric Study in Weld Mismatch of

Longitudinally Welded SSME HPFTP Inlet.

J.B. Min, K.L. Spanyer, and R.M. Brunair.

Structures and Dynamics Laboratory.

N91-23502

Welded joints are an essential part of

pressure vessels such as the space shuttle main

engine (SSME) turbopumps. Defects produced in

the welding process can be detrimental to weld

performance. Recently, review of the SSME high

pressure fuel turbopump (HPFTP) titanium inlet

x rays revealed several weld discrepancies such

as penetrameter density issues, film processing

discrepancies, weld width discrepancies,

porosity, lack of fusion, and weld offsets.

Currently, the sensitivity of welded structures to

defects is of concern. From a fatigue standpoint,

weld offset may have a serious effect since local

yielding, in general, aggravates cyclic stress

effects. Therefore, the weld offset issue is considered in this report. Using the finite element

method and mathematical formulations, parametric studies were conducted to determine the

influence of weld offsets and a variation of weld

widths in longitudinally welded cylindrical

structures with equal wall thicknesses on both

sides of the joint. From the study, the finite element results and theoretical solutions are presented.

Shuttle Main Engine High Pressure Oxidizer

Turbopump Housing Analysis. J.B. Min, L.M.

Cracks at the seal fillet flange and the strut

pilot groove of primary turbine drain passage of

the space shuttle main engine (SSME) high

pressure oxidizer turbopump (HPOTP) have

been observed and reported. Stress information

for critical structural components in the SSME

under actual conditions is necessary for design

and life prediction analysis. However, little

information is available about the stress distribution at this location under various combinations of loadings and environments. Thus, a

stress analysis was conducted to determine an

influence of the various operation and installation

loads on the stresses of the HPOTP main

mounting flange. To do this, a three-dimensional

(3-D) finite element model of the HPOTP housing was generated. A fairly comfortable margin of

stresses at the flange fillet with respect to the

yield stress of Inconel 718 is shown in this

analysis. However, it was revealed that the

bending stress arising from the housing flange

bolt preloads could significantly affect the stress

distribution at the strut pilot groove of primary

turbine drain passage in the HPOTP housing.

Consequently, the information obtained from the

present 3-D analysis results should be useful in

guiding the development of the SSME HPOTP.

Analysis of Lightning Field Changes

Produced by Florida Thunderstorms. W.J.

Koshak. Space Science Laboratory.

N91-25555

A new method is introduced for inferring the

charges deposited in a lightning flash. Previous

nonlinear least-squares methods have used

simple point charge (Q) and point dipole (P)

models to describe ground-based observations

of lightning-caused field changes (AFs). In the

new approach, the AE's are described by a more

general volume charge distribution that is defined

on a large cartesian grid system centered above

the measuring network. We show that a linear

system of equations can be used to relate the

AE's at the ground to the values of charge on this

grid. With this approach, it is possible to apply

more general physical constraints to the charge

solutions, and it is possible to access the

information content of the AE data. Computersimulated AE inversions show that the location

and symmetry of the charge retrievals are

usually consistent with the known test sources.

Analyses of three natural lightning events show

that the linear method provides source

distributions that are in reasonable agreement

with Q- and P-model results.

angle-of-attack variation for control. These

applications are: return from geosynchronous or

lunar orbit to low Earth orbit and planetary aerocapture at Earth and Mars. A number of aerobrake design considerations are reviewed. It was

found that the flow impingement behind the

aerobrake and the aerodynamic heating loads are

the primary factors that control the sizing of an

aerobrake. The heating loads and other loads,

such as maximum acceleration, are determined

by the vehicle ballistic coefficient, the

atmosphere entry conditions, and the trajectory

design. Several formulations for defining an optimum trajectory are reviewed, and the various

performance indices that can be used are evaluated. The "nearly grazing" optimal trajectory

was found to provide the best compromise

between the often conflicting goals of minimizing

the vehicle propulsive requirements and minimizing vehicle loads. The relationship between

vehicle and trajectory design is investigated further using the results of numerical simulations of

trajectories for each aerobrake application. The

data show the sensitivity of the trajectories to

several vehicle parameters and atmospheric

density variations. The results of the trajectory

analysis show that low lift to drag ratio aerobrakes, which use angle-of-attack variation

for control, can potentially be used for a wide

range of aerobrake applications.

This report describes a family of userfriendly, DOS PC based, Microsoft BASIC programs written to provide spacecraft designers

with empirical predictions of space debris

damage to orbiting spacecraft. The spacecraft

wall configuration is assumed to consist of

multilayer insulation (MLI) placed between a

Whipple style bumper and the pressure wall.

Predictions are based on data sets of experimental results obtained from simulating debris

impacts on spacecraft using light gas guns on

Earth. A module of the program facilitates the

creation of the data base of experimental results

that are used by the damage prediction modules

of the code. The user has the choice of three

different prediction modules to predict damage to

the bumper, the MLI, and the pressure wall. One

prediction module is based on fitting low order

polynomials through subsets of the experimental

data. Another prediction module fits functions

based on nondimensional parameters through the

data. The last prediction technique is a unique

approach that is based on weighting the

experimental data according to the distance from

the design point.

In an effort to best utilize all areas of expertise within the Materials and Processes

Laboratory, a Composite Materials Characterization Task Team was developed to help

bring together the various branches within the

Laboratory to develop a comprehensive data

base on composite materials. A "test run" was

performed on IM6/3501-6 carbon/epoxy in which

the material was processed, machined into

specimens, and tested for damage tolerance

capabilities. Nondestructive test data played a

major role in this element of composite characterization. A time chart was produced showing

the time the composite material spent within

each Branch or Division in order to identify those

areas which produce a long turnaround time.

Instrumented drop weight testing was performed

on the specimens with nondestructive evaluation

(NDE) being performed before and after the

impacts. Destructive testing in the form of crosssectional photomicrography and compressionafter-impact (CAI) testing were used. Results

show that the processing and machining steps

needed to be performed more rapidly if data on a

composite material is to be collected within a

reasonable timeframe. The results of the damage

tolerance testing showed that IM6/3501-6 is a

brittle material that is very susceptible to impact

damage.

Atmospheric Turbulence Review of Space

Shuttle Launches. M. Susko. Space Sciences

Laboratory. N91-23215

The primary objective of this paper is to

report on the research and analysis on identifying

turbulent regions from the surface to 16 km for

space shuttle launches. This research has

demonstrated that the results from the FPS-16

radar/jimsphere balloon system in measuring

winds can indeed indicate the presence or conditions ripe for turbulence in the troposphere and

lower stratosphere. It is further demonstrated

that atmospheric data obtained during the shuttle

launches by the rawinsonde in conjunction with

the jimsphere provides the necessary meteorological data to compute aerodynamic parameters

to identify turbulence, such as Reynolds number,

drag coefficient, turbulent stresses, total energy,

stability parameter, vertical gradient of kinetic

energy, Richardson number, and the turbulence

probability index. There is no magic fool-proof

criteria in atmospheric turbulent probability of

occurrence. However, enhanced temperature

lapse rates and inversion rates, strong vector

wind shears, and large changes in wind direction

identify the occurrence of turbulence at the

tropopause. When any two of the above conditions occur simultaneously, a significant probability of turbulence can occur as shown in this

paper.

Electrochemical Studies of Corrosion Inhibitors. M.D. Danford. Materials and Processes Laboratory. N91-17208

The effect of single salts, as well as multicomponent mixtures, on corrosion inhibition has

been studied for type 1010 steel; for 5052,1100,

and 2219-T87 aluminum alloys; and for copper.

Molybdate-containing inhibitors exhibit an

immediate, positive effect for steel corrosion, but

an incubation period may be required for

aluminum before the effect of a given inhibitor can

be determined. The absence of oxygen was found

to provide a positive effect (smaller corrosion

rate) for steel and copper, but a negative effect

for aluminum. This is attributed to the two

possible mechanisms by which aluminum can

oxidize. Corrosion inhibition is generally similar

for oxygen-rich and oxygen-free environments.

The results of this study show that the electrochemical method is an effective means of

screening inhibitors for the corrosion of single

metals, with caution to be exercised in the case

of aluminum.

power and crew resources. The benefits and

costs of each method are analyzed in terms of

resource utilization. In addition to the effect on

individual activities, resource envelopes are

analyzed at the experiment level.

Stress Corrosion Study of Carburized AISI

9310 and Carburized M-50 NiL Steels. P.O.

Torres. Materials and Processes Laboratory.

A stress corrosion cracking (SCC) evaluation of Carburized AISI 9310 and Carburized M50 NiL steels was undertaken. AISI 9310 is a

candidate substitute to 440C for the bearing

inner race in the space shuttle main engine

alternate turbopump development program, and

M-50 NiL may also find applications as a bearing alloy. Round tensile specimens of these

alloys at several stress levels, as well as corrosion samples of AISI 9310, were exposed to

100-percent relative humidity at 38 °C (100 °F).

The maximum tensile stresses that produced no

SCC failures in 1 year of exposure were 172 MPa

(25 ksi) for AISI 9310 and 345 MPa (50 ksi) for

M-50 NiL. Each AISI 9310 steel fracture

showed a circumferential crack between the case

and the core. Both alloys developed rust on the

surface and pitting; however, AISI 9310 rusted to

a greater extent than M-50 NiL. Thin, dense

chrome (TDC) was also evaluated in this program as a corrosion barrier alternative; however,

its protection was minimal. Corrosion spots

visible to the naked eye appeared in less than 5

days of exposure. Although TDC plating on test

specimens prevented the intensive corrosion

attack which occurred in bare samples after a

long time exposure, the TDC plating did not offer

sufficient protection to avoid failures. The results

obtained in this evaluation must be carefully

considered when designing bearing components

made of these materials.

Automating a Spacecraft Electrical Power

System Using Expert Systems. L.F. Lollar.

Information and Electronic Systems Laboratory.

Since Skylab, Marshall Space Flight Center

(MSFC) has recognized the need for large electrical power systems (EPS's) in upcoming

NASA TECHNICAL PAPERS

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.
