FORE WORD 

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. It

Lunar Excursion Module RCS Engine Vacuum 

Chamber Contamination Study. Gary M. 

Arnett, Technical Coordinator. Space 

Sciences Laboratory. N70-13418. 

The objective of this study was the definition 

of future contamination studies and procedures, and 

the investigation extended to the effects of the Reaction Control System (RCS) plume on optical flight 

experiments. This report, is concerned with the 

effects of the RCS plume deposits on the test beds 

along with the characteristic changes that occur once 

these deposits are exposed to the laboratory atmosphere. Test beds consisting of various optical 

surfaces were exposed to an LM-RCS rocket engine 

plume in the vacuum chamber A. Analysis of the 

contaminated test beds included optical measurements 

ranging from the near-ultraviolet through the farinfrared region together with mass spectrometer 

identification of the deposits.

Natural Environment Criteria for the NASA 

Space Station Program. Don K. Weidner, 

ed. Aero-Astrodynamics Laboratory. 

This document provides natural environment 

criteria for the NASA Space Station Program with 

emphasis on the 1975-1985 time period. Information in the disciplinary areas of atmospheric and 

ionospheric properties, radiation, solar cycle 

predictions, geomagnetic field, astrodynamic constant, and meteoroids is given for the Earth, Moon, 

Mars, Venus, and interplanetary space. This 

document, originally published on August 1, 1969, 

has been revised to include the planetary and lunar 

environment criteria needed for preliminary Space 

Station studies relative to a manned Mars landing, 

a Venus flyby, and a lunar mission. It supersedes 

earlier versions of NASA TM X-53865.

Z Transform and the Use of the Digital 

Differential Analyzer as a Peripheral 

Device to a General Purpose Computer. 

Donald Nalley. Computation Laboratory. 

N70-19896. 

A feasibi€ity study determined whether the 

Digital Differential Analyzer (DDA) can be used as 

a peripheral device; that is, a computer system 

programmed in FORTRAN IV or some other standard language in which certain manipulations could be 

accomplished on the DDA by calling a subroutine. 

In this study, consideration was given to Large Scale 

Integrator Circuits (LSI) , because it was felt that 

suitable IS1 would make the DDA a more feasible 

device. 

It appears that the DDA as a standard peripheral 

device with automatic patching is indeed feasible. 

However, implementation with LSI is questionable 

presently, but this may become feasible soon.

Probability Distributions for Thunderstorm 

Activity at Cape Kennedy, Florida. Lee W. 

Falls, William 0. Williford, and Michael 

C. Carter. Aero-Astrodynamics Laboratory. 

Several statistical distribution functions are 

investigated as prospective models to represent the 

variation of thunderstorm activity at Cape Kennedy, 

Florida. Statistical methods are presented using 

the latest and most comprehensive thunderstorm data 

available. The conclusion is reached that the 

negative binomial distribution and a modification of 

the negative binomial distribution are adequate 

statistical models to represent "thunderstorm events" 

and "thunderstorm hits,

Studies in System Simulation. R. Saeks. 

NASA-ASEE Summer Faculty Fellowship 

Program. N69-41152. 

The results of three mathematical studies of 

the feasibility of various methods of large scale 

digital system simulation are reported. Specific 

studies deal with the effects of applying numerical 

techniques directly to the components of a system, 

approximation techniques fDr reducing the order of 

subsystems, and data compression techniques for 

the computer storage of the large topological 

matrices encountered in system simulation.

A Direct Measurement of the Most Probable 

Preferred Angular Velocity of Turbulent 

Structures by Optical Correlation of Laser 

Schlieren Signals. B. H. Funk. AeroAstrodynamics Laboratory. N70-12209. 

A method which potentially provides the means 

for separating the translational and rotational motion 

of turbulent structures is introduced. Simple twodimensional models are used to relate the skewness 

of cross-correlograms computed from laser 

schlieren signals to the rotation of flow disturbances. 

The method, referred to herein as the method of 

"forced similarity, '' is discussed with respect to 

application to the turbulent free shear layer of an 

axisymmetric supersonic jet. Experimental results 

show that the shape of the cross-correlogram in the 

neighborhood of the "peak" is strongly influenced by 

rotational motion, and therefore, it becomes necessary to account for the effect in order to'determine 

the correct statistical properties of the turbulence.

Experiments in Hydrodynamic Grease 

Bearings. John L. Burch and Peter H. 

Broussard, Jr. Astrionics Laboratory. 

N70- 1 1874. 

The suitability of using hydrodynamic conicaland spherical-shaped spiral-grooved grease bearings 

as a replacement for gyro ball bearings has been 

investigated. Grease bearings have been built and 

tested for rotors which vary in diameter from a few 

centimeters to 30.5 centimeters and in weight from 

a few grams to 22.7 kilograms. Speeds from 

f 2 000 to 50 000 rpm have been maintained for 

hundreds of hours in both air and vacuum environments. Generally, these bearings have operated 

satisfactorily and retained their lubricant. 

Guidelines on probable climatic extremes and 

probabilities-of-occurrence of terrestrial environment data specifically applicable for NASA space 

vehicles and associated equipment development 

are presented. The geographic areas encompassed 

are the Eastern Test Range (Cape Kennedy, Florida) ; 

Huntsville, Alabama; New Orleans, Louisiana; the 

Western Test Range (Point Arguello, California) ; 

Sacramento, California; Wallops Test Range 

(Wallops Island, Virginia) ; White Sands Missile 

Range, New Mexico; and intermediate transportation areas. In addition, sections have been included 

to provide information on the general distribution of 

natural environment extremes in the United States 

(excluding Alaska and Hawaii) , cloud cover, and 

some worldwide climatic extremes.

Optimal Transfer Trajectories From Earth 

Parking Orbit to Various Terminal Conic 

Constraints and Modifications to the ROBOT 

Computer Program. Rodney Bradford. 

Program Development. N70-15035. 

Reference optimal (minimum fuel consumption) 

transfer trajectories were computed by the minimum 

Hamiltonian-steepest ascent method for departure 

from a circular parking orbit about the earth to 

various terminal conic constraints. Terminal conditions were a circular orbit at synchronous altitude, 

3! 862 km, an elliptical orbit with apogee at 

synchronous altitude ( in-and-out-of -parking-orbitplane), and an injection burn into a typical 1973 Mars 

mission hyperbolic orbit. The vehicles used to 

perform these transfers were the S-IVB stage and 

the Command Service Module. Also included is a 

typical ascent.trajectory profile utilizing a two-stage 

Saturn IB launch vehicle. Detailed orbital and 

trajectory profile parameters are presented in 

tabular form.

A New Interpretation of the Explorer XVII

and Its Implications to Orbital Analysis. 

James 0. Ballance. Aero-Astrodynamiss 

Laboratory. N69-38272. 

The response of the modified Redhead magnetron 

density gauges used on the Explorer XVII and Explorer XXXII satellites has been analyzed by using the 

transmission probabilities and time response characteristics caused by geometry and gas-molecule/ 

surface interactions. It was found that the very 

evident fluid dynamic response characteristics of the 

data required an interpretation which uses low energy 

and momentum exchange for the gas on the initial 

wall collisions with total loss of atomic oxygen. An 

additional signal caused by a process - most likely 

to be recombination - taking place on the wall of the 

gauge is suggested. For the example used, there is 

a factor of two between the derived density based on 

the original assumptions and the density based on the 

new interpretation.

NASA TECHNICAL MEMORANDA 

The effects of varying the radio frequency (rf) 

sputtering parameters on the dielectric properties 

of resultant deposited thin films of Teflon is discussed. Electrode voltage, electrode spacing, and 

sputtering pressure were the parameters studied, 

and film thickness was the controlled variable. The 

dielectric constant, dissipation factor, dielectric 

strength, and resistivity were determined. In 

general, the dissipation factor increases with film 

thickness, while resistivity and dielectric strength 

decrease with increasing thickness. All paraFeters 

measured indicate a strong anomaly at 3 000-A film 

thickness.

Radiographic Interpretation Guide for 

Aluminum Alloy Welds. P. C. Duren and 

E. R. Risch. Astronautics Laboratory. 

The problem of radiographic interpretation has 

plagued the X-ray method of nondestructive testing 

since its beginning. In an attempt to achieve a more 

accurate interpretation of radiographic images of 

aluminum alloy welds, a program designed to correlate specific images with corresponding discontinuities was initiated. Radiographs were made of 

welds that contained different types of discontinuities. 

Subsequent metallographic studies were made to confirm the image types and shapes as depicted in the 

radiographs. These experiments required very 

precise welding techniques to produce the various 

types of discontinuities found in typical aluminum 

welds. Exact radiographic techniques and careful 

metallographic methods were also necessary to 

achieve program objectives. Lack of agreement on 

terminology has also plagued the advancement of 

radiographic interpretation. Therefore, the 

radiographic terms used in this report have been 

carefully defined to eliminate as many interpretational e r r o r s a s possible. The resultant data show 

clearly that radiographic interpretation can be placed 

on a scientific basis.

Duren. Astronautics Laboratory. 

N70-17360. 

NOPCO BX-250, a polyurethane spray foam is 

now used as cryogenic insulation for S-I1 stages of 

the Saturn vehicle. This application has required 

considerable effort in the development of nondestructive methods to evaluate the mechanical 

integrity of foam to metal bonds. Certain inspection 

problems associated with low density foamaluminum composites are evaluated in this report. 

The development of audio frequency methods required to overcome these difficulties are described. 

Additional effort was required to adapt one of these 

audio frequency methods and to develop radiographic 

techniques for the detection of voids in the foam.

Spectral Emission Properties of Selected 

Igneous Rocks in the 2.8- to 13.5-Micron 

Region. William D. Hunton. Space Sciences 

Laboratory. X70-13226. 

Several laboratories are performing studies in 

the area of remote identification of rocks and 

minerals from their infrared reflections and emission spectra. The results of the studies should be 

useful in such programs as Apollo Applications. 

However, more laboratory data on known specimens 

are needed to identify rocks and minerals in situ. 

In this report emission properties of selected 

igneous rocks in the 2.8- to 13.5-micron region are 

discussed. A circular variable filter wheel infrared 

spectroradiometer was used to obtain spectra from 

rough rock chunks heated to between 46" and 47" 

Celsius. The sampIes showed either several shallow 

emission minima or just a general departure from 

blackbody radiation. None showed any narrow 

bandwidth emission minima. This work has shown 

that the circular variable filter spectroradiometer is 

a useful tool in the field of identification of rocks 

whose temperatures are not highly elevated. It is 

useful in either distant or close scanning of rocks 

of unknown composition. Also, the spectra included 

should provide a useful catalog for work in infrared 

emission analysis.

Nucleate Pool Boiling of Saturated Freon 

113 in a Reduced Gravity Environment.

NASA TECHNICAL MEMORANDA 

Pool boiling of Freon 113 was investigated in 

a body force field less than standard gravity using 

the 4-sec drop tower. Emphasis was placed on the 

behavior of the nucleate portion of the pool boiling 

curve. The growth and departure of individual 

bubbles were also investigated. A transient 

calorimeter technique was used to obtain boiling 

curve information. This technique allowed the use 

of a heater of sufficient size to eliminate the problem 

of heater geometry influencing the boiling behavior 

while avoiding the necessity of achieving steady state 

during the short drop time available. The results 

indicate that the location of the pool boiling curve is 

a function of both acceleration level and surface 

orientation.

Walter L. Green. Astrionics Laboratory. 

N70-206 55. 

A dead reckoning navigation system for the 

manned lunar roving vehicle is presented. The basic 

hardware for the system is two free gyros mounted 

to the frame of the vehicle, the wheel odometers and 

tachometers, and a signal processor. The math- 

‘ematical equations for the navigation system are 

developed and related directly to the vehicle velocity 

and the gimbal angle readings. A digital simulation 

program is written for the navigation system for performing error analysis. The simulation can be used 

for determining the effects of gyro drifts and system 

misalignments for any selected lunar surface profile. The results of a study with selected ranges of 

gyro drift rates and misalignments for a particular 

surface profile are given.

Electron Bremsstrahlung Shielding at 

Synchronous Altitude by Electron Trapping in 

Dielectrics. D. L. Hollis. Space Sciences 

Laboratory. N70 - 150 5 8. 

A theoretical study is made of synchronous altitude electron bremsstrahlung shielding by electron 

trapping in a layer of dielectric material on the outer 

surface of a spacecraft. Traps in the insulating 

material retain bombarding electrons and thereby 

produce an internal spacecharge field of large 

magnitude. The electric field repels or slows additional electrons. This acts to reduce bremsstrahlung 

production, lower the photon energy, and enhance 

photon absorption. The breakdown phenomenon 

causes the shielding effect of the trapped electrons 

to be cyclic. Qualitative calculations indicate that a 

40-percent decrease in mass results when a thin 

layer of polyethylene instead of lead is used in reducing bremsstrahlung in an aluminum wall to the 

same level. Suggestions are given to modify existing 

Monte Carlo codes for this particular application.

Large Angle Method for Space Vehicle 

Angular Momentum Desaturation Using 

Gravity Gradient Torque. Hans F. Kennel. 

Astrionics Laboratory. N70-19867. 

The angular momentum desaturation method is 

based on the use of the gravity gradient torques. 

Large angular maneuvers maximize the effectiveness 

of the desaturation method for the case where the 

mission requires the minimum moment-of-inertia 

axis to point toward some celestial object far the 

nonocculted part of the orbit. The desaturation 

method is developed under the assumption that the 

diffekence between two of the principal moments of 

inertia is negligible. A constant attitude with respect 

to the gravity gradient direction is held during the 

desaturation period. This allows maximization of 

the available gravity gradient desaturation torque 

which is necessary since the assumed moment-ofinertia distribution (in relation to the mission requirements) is a very poor candidate for angular 

momentum desaturation using the gravity gradient, 

especially when relatively large aerodynamic 

disturbance torques are present.

NASA TECHNICAL MEMORANDA 

In an attempt to leap-frog long tack welds, a 

reliable tack weld detector was developed to sense 

approaching tack welds. This sensor is perhaps the 

most significant development to result from the phase 

of the program. It is concluded that the present 

MSFC system should not be located close to the 

torch when tack welds are employed to hold the weld 

joint; however, it is recommended that the present 

electro-inductive system should be considered a 

boon for the development of an aitoaatic tack welder 

because of its homing capabilities. With a memory 

system, it seems feasible that the MSFC developed 

system could be used with short tack welds. As an 

evaluation and a comparison of MSFC's transducer 

with the latest optical tracking transducer is drawn

Astrionics Laboratory. N70-18797. 

For an optimum design, the weight, energy 

consumption, and operational flexibility of the traction 

drive system for a lunar roving vehicle must be 

considered along with the power supply, motor, and 

power train. Other problems considered in this 

paper include: environment and motor dissipation, 

motor type (i.e., ac or dc) and commutation if dc, 

motor controller (i. e. , switching of large currents) , 

delivery of torque at varying speeds, power train, 

use of regenerative braking and conservation of 

energy, and power supply voltage variation. These 

problems are studied in view of certain general 

system specifications, which fall into weight, performance, and environment categories. Tradeoff 

studies are considered for optimization in each of 

these areas. Special consideration is given to the 

controller and system design as it pertains to 

regenerative braking and the conservation of energy. 

Some aspects of changing the modes of motor operation to satisfy extreme performance requirements of

The channeling of debris by a double-sheet 

structure separated by a honeycomb material has 

been reported by many investigators in the hypervelocity field. It has been suggested that this 

channeling will reduce the protective capability of 

such a structure when compared to an identical 

structure without honeycomb. A series of tests was 

conducted by this laboratory to gain an understanding 

of the characteristics of the channeling phenomena 

and the extent to which the channeling would affect 

the ballistic limit of a honeycombed structure. It 

was found that the particular honeycomb tested exhibited greater protective ability than an identical 

double-sheet structure without the honeycomb for 

velocities between 3.5 and 8.23 km/sec.

The preliminary analysis and conceptual design 

of a baseline spacecraft along with supporting technical data and discussion of mission and spacecraft 

alternatives are presented. 

The High Energy Astronomy Observatory treated 

in this work is the first of four planned spacecraft 

in the High Energy Astronomy Observatory program, 

designated in this report as HEAO-A. The primary 

mission objective of the HEAO-A spacecraft is to 

completely survey the celestial sphere for high

with primary emphasis on the galactic belt region; 

the secondary mission objective is selective pointing 

at specific celestial targets. 

To ensure a comprehensive system analysis

spacecraft was defined with a realistic, but hypothetical, experiment package. Total weight of the 

baseline spacecraft is approximately 19 000 pounds 

and launch is assumed from ETR on the Titan-IIID

four detectors are required for monitoring winds of 

unknown azimuthal direction. They are conveniently 

placed at the corners of a square sitting on level

A formula for the frequency shift of a maser

because of the gravitational potential difference and 

special relativistic effects, this formula is shown to 

contain terms that depend on the spatial part of the 

metric tensor. These extra terms cannot be derived 

using only the equivalence principle. It is shown that 

the frequency shift given by these additional terms 

appears to be observable with presently attainable 

maser accuracies. The measurement of the additional effects will yield the same information about 

the metric as will the geodetic precession of a

Torsional Vibration Analysis of Saturn 

Vehicles. Larry Kiefling and Frank Bugg. 

Aero-Astrodynamics Laboratory. 

Methods for finding the torsional vibration modes 

for either a beam-like vehicle, such as Saturn V, 

or a multibeam vehicle, such as Saturn IB, are 

developed. The single beam analysis is a Stodola 

iteration method. The Saturn IB vehicle is mathematically modeled as a system of beams and connecting members. The modes of the vehicle are 

composed of the superimposed components of normal 

beam modes plus rigid body motion. A comparison 

is made with dynamic test data. The calculated 

frequencies differed from the experimental values 

by an average of 8 percent for the cases compared.

A decision algorithm, that has been specifically

Atmospheric data were obtained by various 

investigators from 38 rocket-probe flights and two 

satellite-borne absorption spectrometers. The 

data sample is by no means complete, but should 

provide valuable inputs to studies concerning the 

structure and variability of the atmosphere. Atmospheric temperature, mass density, and constituent number densities of Nz, Oz, 0, He, and H 

as calculated from the MSFC Modified Jacchia 

Model Atmosphere, 1967, for the conditions of a 

particular observation are tabulated from 120 to 

1000 km for most of the observations. These data 

should also provide valuable inputs to various 

studies. In using these data, however, the investigator should consider the limitations (constant 

120-km boundary conditions, empirical temperature, 

etc.) of the MSFC Model Atmosphere.

The Generation of X Rays in Planetary 

Nebulae. Klaus Schocken. Space Sciences 

Laboratory. 

The evolution of planetary nebulae and the production of X rays will be summarized from the 

literature. Planetary nebulae emit continuous 

radiation which originates by free-free transitions 

involving kinetic energy losses of free electrons in 

16 
NASA TECHNICAL MEMORANDA 

the electrostatic fields of ions. These free-free 

emissions are responsible for the radiation observed 

in the radio frequency spectra. They also contribute 

in the visible and infrared regions. Therefore, if 

X rays are generated by planetary nebulae, it can be 

assumed that they will also be produced by freefree transitions. However, free-free radiation will 

be measured along with free-bound radiation. A 

formula is given for the intensity of the combined 

continuum for an ionized gas with a Maxwellian 

distribution of the electron velocities.

X Radiation in Binary Stars. Klaus Schocken. 

Space Sciences Laboratory. 

The properties of close binary stars and old 

novae as they are known will be summarized from the 

literature sources listed in the bibliography. A 

binary system originates with or results from the 

splitting of a single star into two components caused 

by rotational instability during the contraction of the 

star. The assumption is made that, to become a 

nova, it is a necessary conditionfor the star to be a 

member of a close binary system consisting of a 

blue and a red star, with a stream of gas flowing 

from the red to the blue star and forming a shell 

around the blue star to generate the observed bright 

emission lines that indicate that this gaseous shell 

moves with the blue star. Assuming that the explosive process has taken place in the nova, a shock 

wave will penetrate the surface, forming an 

expanded atmosphere in a time that is too short for 

appreciable loss of radiation. When an electric field 

exists in a plasma with a density such that the electrons whose velocity surpasses a certain critical 

value will gain more energy from the field than they 

lose by collisions, runaway electrons will be generated. The hypothesis is made that runaway electrons are the source of deceleration X radiation in 

the atmosphere of a nova.

The Technical Micronics Control (TMC) process 

for electropolishing a variety of metals and metal 

alloys was investigated. The electropolishing solution 

produced lustrous surfaces on stainless steel, brass, 

copper, nickel, aluminum, and steel; it produced only 

semibright surfaces on Invar and Ren6 41, but 

produced a considerable amount of metal smoothing. 

The passivation of stainless steel was improved

substantially by this method over that of conventional 

acid passivation methods. TMC polished surfaces 

of stainless steel, brass, and carbon steel did not 

accept an electroplate with good adherence but such

than mechanically polished surfaces. Based on results of this study, the TMC process is recommended 

for polishing and smoothing most metals and for

Nineteen observations of the temperature profile are used to analyze and to develop a model of 

the potential temperature profile e( z) in the planetary boundary layer. The observations consist of 

mean flow temperatures observed at the 3-, 18-, 

30-, 60-, i20-, and 150-meter levels at the NASA 

meteorological tower site at Kennedy Space Center, 

Florida. It is provisionally concluded that the 

dimensionless potential temperature gradient

RL= -fLo/u,ko , where T,,, and u:ko denote 

surface values of the friction temperature and friction velocity, L is the surface Monin-Obukhov

The distance constant for the cups (wind speed sensor) was found to be approximately 0.8 and 1.3 

meters for the two types tested. Values for the 

damping ratio of approximately 0.48 and 0.40 were 

found for the two types of vanes. The main point of 

interest in the investigation of the propeller-type 

anemometer, other than its response, was how the 

indicated speed varied as a function of angle of attack. 

For an angle of attack (angle formed by the longitudinal axis of the anemometer and the wind flow

Turbulence Measurements in Supersonic,

Johnston. Aero-Astrodynamics Laboratory. 

N70-20577. 

A new optical crossed-beam technique was used 

to measure the turbulence properties of two supersonic, shock-free, cold air jets. The method is 

based on the absorption of ultraviolet radiation by 

air. The measurements were highly successful in 

that reasonable and consistent values of the turbulence properties such as convection speeds, length 

scales, and spectra were obtained, and the data 

generally followed the trends set by hot-wire 

measurements in subsonic jets. The most interesting 

feature of the crossed-beam technique is the possibility of a direct measurement of three-dimensional 

spectral density. However, the demonstration that 

the crossed-beam technique can be used for turbulence measurements in supersonic flow is considered 

to be the major accomplishment.

Longitudinal Mass -Spring Modeling of 

Launch Vehicles. Rudolf F. Glaser. 

Astronautics Laboratory. N69-34970 

To determine longitudinal axisymmetric vibration modes on launch vehicles, simplified models 

must be established. As a first step, a launch 

vehicle can be idealized by a chain of masses, helical 

springs, and liquid-filled containers. However, the 

realistic mass-spring representation of the liquid 

propellants supported by the elastic container wall is 

the problem. In this report, application of Galerkin's 

method to the equations of motion of the above simplified system is proposed, using the containerliquid modes with special normalization factors as 

coordinate functions. This method, identical with 

the Ritz method in this case, is favorable in several 

aspects. First, the resulting model is based on the 

energy law. The use of the container-liquid modes, 

however, results in accurate representation of 

sigaificant structural and inertial characteristics of 

the container-liquid system. The special normalization of the coordinate functions converts the 

container-liquid systems directly in lumped parameter systems, having a number of degrees of 

freedom equal to the number of coordinate functions 

used. In this report, the containers are assumed 

cylindrical membranes with flat, rigid bottoms. For 

simplicity, typical tandem parts of vehicles, consisting of only one or two solid masses and springs 

and one liquid-filled container, are examined. If 

one-term approaches are considered, the resulting 

model can be interpreted as an actual spring-mass 

model. Because of the rapid decrease of the 

equivalent modal masses (with increasing mode 

number) , restriction to one-term approaches does 

not mean considerable loss of accuracy. Comparison of analytical results with experiments provides 

satisfactory agreement. In this way, the use of 

large matrices in the final eigenvalue problem can 

be avoided.

of the problem is to describe the mathematical

a basis for comparing the integration techniques; 

and to generate sufficient comparison data to establish which integrationtechnique is the most practical to 

use in this model from a standpoint of computer run 

time and accuracy. An analysis of the data showed 

a fourth-order formula to be the most practical 

integration technique to use in computer programs of 

this type from a standpoint of computation time, 

accuracy, and stability of the solution.

Final Report: Saturn V, S-IVB Panel Flutter 

Qualification Test. J. J. Nichols. Astronautics Laboratory. N69-38808. 

This report gives results obtained from an 

evaluation of data taken during the Saturn S-IVB 

forward skirt flutter test conducted at Arnold Engineering Development Center, Tullahoma, Tennessee, 

during the period from October 30 through November 

6, 1967. A fullscale segment of the S-IVB stage 

forward skirt was tested to determine the flutter 

characteristics of the thin skin panels bounded by 

internal rings and external stiffeners. 

Since the skin panels were subjected to more 

severe flutter conditions than would be expected 

during flight, it is concluded that the S-IVB stage 

panel flutter is not critical for all Saturn IB and

A Theoretical and Experimental Study of 

Unsteady Flow Processes in a Ludwieg

N70-10710. 

The application of a numerical procedure 

generally referred to as the method of characteristics 

to calculate the nonsteady discharge of compressed 

air through a Ludwieg tube type of wind tunnel is 

presented. The mathematical model that underlies 

the numerical procedure assumes the flow through 

the wind tunnel to be time-dependent, onedimensional, and compressible. The theoretical 

results presented were obtained from a computer 

program developed for this problem. Diaphragm 

rupture, variations in cross-sectional areas, contact surfaces, shock waves, and the interaction and 

reflection of contact surfaces and shock waves are 

included in the computer program. The theoretical 

results are compared with static and total pressures 

measured in a Ludwieg tube wind tunnel that has 

recently begun preliminary operation at MSFC. 

Good agreement between theory and experiment is 

achieved for the cases in which the flow in the test 

section was subsonic. Only fair agreement between 

the one-dimensional theory and experiment was 

achieved in the supersonic test sections. This difference is believed to be attributed to the twodimensional character of the flow and the extensive 

flow separation that occurs in the supersonic nozzles 

during the early development of the flow.

Numerical Solution of Differential Equations 

Using Obrechkoff Corrector Formulas. 

Joseph S. Rosen. Computation Laboratory. 

N70-10685. 

The solution of differential equations by 

predictor-corrector formulas which give highorder accuracy is considered. The corrector 

formulas are obtained from an extension of 

Obrechkoff's formula. These formulas are characterized by the fact that they contain higher derivatives of the unknown function y( x) , and if their 

derivatives are readily determinable, fewer terms 

are needed for a given order as compared to other 

multistep methods which do not involve derivatives. 

Corresponding to these corrector formulas, certain 

new predictor, or extrapolation, formulas are suggested. These formulas also make use of the derivatives used in the corrector formulas.

Longitudinal and Lateral Spectra of 

T.urbulence in the Atmospheric Boundary 

Layer. George H. Fichtl and George E. 

McVehil. Aero-Astrodynamics Laboratory. 

N70-19272. 

An engineering spectral model of turbulence is 

developed with horizontal wind observations obtained 

at the NASA 150-meter meteorological tower at 

Cape Kennedy, Florida. Spectra, measured at six 

levels, are collapsed at each level with Monin 

coordinates, where the longitudinal or lateral spectral 

energy density, the surface friction velocity, and the 

mean wind speed at some height are represented. 

A vertical collapse of the dimensionless spectra is 

produced by assuming they are shape invariant in 

the vertical. An analysis of the logarithmic spectruii 

in the inertial subrange, at the 18-meter level, 

implies that the local mechanical and buoyant production rates of turbulent kinetic energy are balanced by the local dissipation and energy flux divergence, respectively.

Shear Layer and Jet Instability in Stratified 

Media. George H. Fichtl. AeroAstrodynamics Laboratory. N70-2 16 19. 

The stability to small perturbations of shear 

layer and jet flows in atmospheres with potential 

temperature is investigated. The problem is reduced 

to a characteristic value problem for the dimensionless wave frequency which appears in a second-order 

differential equation with the dependent variable being 

the horizontal and temporal Fourier transform amplitude of the vertical component of the perturbation 

momentum vector. Broken-line profiles of jet flow 

and potential temperature are used in the analysis of 

this problem. 

Integral equations, over the domain of the fluid, 

which contain both quadratic forms and interfacial 

contributions, are derived. The interfacial terms 

vanish for continuous flows, and the theorems of 

Synge, Howard, and Miles follow. A necessary and 

sufficient condition for instability is also obtained 

for continuous flows; however, its usefulness is 

compromised by integrands which depend on both the 

basic state flow and the dependent variable of the 

governing differential equation.

Discontinuous Flows and Free Streamline 

Solutions for Axisymmetric Bodies at Zero 

and Small Angles of Attack. Heinz G. Struck. 

Aero-Astrodynamics Laboratory. 

N70-21527. 

Except for a few numerical results, nothing has 

been published, comparable in magnitude to the twodimensional case, concerning free streamline solutions of the axisymmetric problem. Since the method 

of using conformal transformations is not available in 

axisymmetric and three-dimensional flows, it is 

necessary to adopt approximate methods for the free 

streamline analysis. In this study an integral equation procedure has been applied to calculate the free 

streamline flow behind axisymmetric bodies at zero 

and small angles of attack. The method uses a modified condition for irrotational flow and iterates until 

the proper streamline location is found. Some of the 

results obtained by this procedure will be discussed 

in this report.

Effect of Wall Roughness on the Damping of 

Liquid Oscillations in Rectangular Tanks. 

Frank M. Bugg. Aero-Astrodynamics Laboratory. N70-20583. 

An experimental investigation was made to 

determine the effectiveness of wall roughness for 

damping liquid oscillations in rectangular tanks. 

Roughness with height equal to 0.427 percent of the 

wetted wall area gave damping 65 percent greater than 

the smooth wall damping. Comparisons were made 

with viscous damping theory.

Stability of Constant-Gain Systems With 

Vector Feedback. George L. von Pragenau. 

Astrionics Laboratory. N70-21840. 

Vector feedback is defined as a multivariable 

feedback loop that cannot be opened at a single nodal 

point. Such systems are treated for the constant-gain 

24 
NASA TECHNICAL NOTES 

(linear and time-invariant) case by decomposing 

such systems into stable subsystems. Ordinary 

algebraic operations always permit such decompositions. Relatively simple necessary and sufficient 

conditions result, and stability is analyzed for a 

closed-loop system in which the input is a disturbance vector and the output is a feedback vector. The 

proposed method permits a drastic reduction in the 

dimensions of a problem because of a building block 

approach. The state-space method is compared and 

found to be the limit case where the building block 

formulation assumes its maximum dimensions. 

Noncontrollable and nonobservable system parts are 

not nonconsequential because all subsystems are 

stable. The method presented was successfully used 

for the stability analysis of the Apollo-Saturn V pogo 

phenomenon where eigenvalues numbered well over 

a hundred. This problem was reduced to a single 

Nyquist plot analysis of a 4 by 4 determinant, 

demonstrating the power in reducing dimensions of 

a problem that would have been a formidable task 

for the state-space approach. The proposed method 

is generally applicable.

A Study of Radiation Heat Transfer From a 

Cylindrical Fin With Base Surface Interaction. 

Charles A. Cothran. Astronautics Laboratory. 

N70-24257. 

This paper presents a study of the temperature 

distribution of a cylindrical fin transferring heat 

simultaneously by internal conduction and by surface 

radiation. The temperature distribution was studied 

considering the fin only and the more complex case 

of surface interactions with a circular base. Equations are derived for the temperature distribution of 

the fin only, the fin with base surface interactions 

when both surfaces are black, and also the case of 

gray diffuse surfaces. Solutions to the equations are 

obtained by numerical techniques, the analysis is 

verified experimentally, and the results are given.

A Finite Element Approach to the Structural 

Instability of Beam Columns, Frames, and

Laboratory. 

A nonlinear stiffness matrix for a beam column 

element subjected to nodal forces and to a uniformly 

distributed load is developed from the principle of 

virtual displacements and the bifurcation theory of 

elastic stability. Three cases of applied load behavior 

are considered. The buckling load of a uniform 

circular arch is calculated as an example.

Nonlinear Fluid Oscillations in a Partially 

Filled Axisymmetric Container of General 

Shape. John Ray Admire. Astronautics 

Laboratory. 

A solution for finite-amplitude free oscillations 

of fluid in a partially filled axisymmetric container 

is presented. The formulation of the problem resulted in a nonlinear boundary value problem where 

the nonlinearity occurred in the boundary condition at 

the free surface of the fluid. The boundary condition 

at the container wall and the differential equation are 

linear. The solution is obtained by first linearizing 

the free surface boundary condition and solving the 

resulting linear boundary value problem. Then, 

using the linear solutions, which satisfy the differential equation and the boundary condition at the 

container wall, a solution is found that satisfies the 

nonlinear boundary condition at the free surface 

asymptotically. A solution through the third-order 

term is developed. Numerical results are obtained 

for finite-amplitude standing waves near the first 

antisymmetric linear mode in three axisymmetric 

vessels. Results are found for three containers, a 

cylindrical tank with an ellipsoidal bulkhead, a 

cylindrical tank with a conical bulkhead, and a cylindrical tank with a truncated conical bulkhead.

Method for Calculating Rocket Engine 

Structural Loads. Jerrell M. Thomas. 

Astronautics Laboratory. 

A method for calculating structural loads iu a 

rocket engine-actuator-vehicle system is developed. 

The engine is attached to the vehicle by a universaltype gimbal joint and by two actuators. The engine 

is assumed to be a rigid body. Either the actuator 

loads or the engine angular acceleration is assumed 

to be known with a calculation of the other required. 

A set of algebraic equations is developed from which 

25 
NASA TECHNICAL NOTES 

the unknown actuator loads or angular acceleration 

and the forces and moments at the gimbal point can 

be calculated.

N69-30753. 

New first-, second-, third-, and fourth-order 

Runge-Kutta formulas with stepsize control procedures are derived. These new Runge-Kutta 

formulas have very small truncation errors; therefore, their application reduces computer time 

substantially. These low-order formulas are also 

applicable to parabolic partial differential equations 

as encountered in heat transfer problems. Examples 

for ordinary and partial differential equations are 

presented. In these examples the new formulas 

require only a fraction of the computer time of 

conventional formulas.

A mathematical model is used to represent 

Opik's 1958 physical theory of meteors in a form 

convenient for programming the computation of 

meteoroid photometric mass values. Subsamples of 

333 photographic meteors from McCrosky and Posen's 

sample are selected with respect to magnitude scaled 

for minimum velocity. A statistical comparison 

between the 1958 Opik result and the 1933 opik 

provisional result, the Harvard-Meteor project 

basis for mass values, is given. Meteor and orbit 

parameter distributions and mean cumulative flux 

in absolute units for mass, momentum and energy are 

given separately for the terrestrial influx and for the 

lunar and interplanetary vehicle onfluxes.

Calibration of Pegasus and Explorer XXLII 

Detector Panels. Robert J. Naumann, 

David W. Jex, and Clyde L. Johnson. Space 

Sciences Laboratory. N69-36 985. 

Several series of tests were conducted to establish the ballistic limit for the various Pegasus and 

Explorer XXIII detector panels-. In these tests, 

extremely small, carefully sized beads were launched 

in a velocity range that included the perforation 

threshold. By varying the size, a ballistic limit 

curve was established on a mass-velocity plot. Such 

curves were then extrapolated to average meteor 

velocity to obtain the characteristic mass for each 

sensor. Additional tests were conducted on the 

Pegasus panels using the Pegasus test tool, which 

contains the identical electronic circuitry used by 

the flight models. These tests included hot and cold 

tests, thermal cycling after impact, oblique impacts, 

etc. Several types of anomalous events noted in the 

operation of the spacecraft could be simulated in this 

manner. Some indication of the dependence of detection threshold upon size was obtained, and the 

implications of these tests in the analysis of the 

results will be discussed. 

The One-Dimensional Time-Dependent 

Interaction of a Satellite with the Ionospheric 

Plasma. Nobie H. Stone and John W. Sheldon. 

Space Sciences Laboratory. N70-24381. 

A theoretical study and numerical solution are 

presented for the one-dimensional, time-dependent 

problem of a streaming, nonuniform, fully ionized, 

collisionless plasma impinging upon a stationary, 

flat conducting plate oriented perpendicularly to the 

flow of the plasma. The problem is intended to 

model the interaction of the frontal surface of a satellite with the ionospheric plasma. The timedependent equations that describe the one-dimensional 

problem are established, and from them the steadystate equations are derived. These steady-state 

equations are solved for the spatial dependence of the 

electric field, which is seen to be a reasonable form 

and to agree with previous work on more complicated 

configurations. Finally, a numerical method of 

solving the time-dependent equations is presented 

and applied to two special cases: (1) for a plate that 

has no initial charge, and (2) for a system that is 

initially in an equilibrium state and proceeds to a 

second equilibrium state because of a step transition 

in the plasma parameters.
