NASA TECHNICAL MEMORANDUM

TM-103514 October 1990Eddy Current Inspection of Graphite FiberComponents. Dr. G.L. Workman and C.C.Bryson. Materials and Processes Labora-tory. N91-10294

The recognition of defects in materialsproperties still presents a number of problemsfor nondestructive testing in aerospace systems.This project attempts to utilize current capabili-ties in eddy current instrumentation, artificialintelligence, and robotics in order to provideinsight into defining geometrical aspects of flawsin composite materials which are capable ofbeing evaluated using eddy current inspectiontechniques. The unique capabilities of E-probesand horseshoe probes for inspecting probes forinspecting graphite fiber materials have beenevaluated and appear to hold great promise oncethe technology development matures.

This preliminary phase report describes theinitial results of modeling eddy current inter-actions with certain flaws in graphite fibersamples.

TM-103515 October 1990Test and Model Correlation of theAtmospheric Emission Photometric ImagerFiberglass Pedestal. H.M. Lee III and L.A.Barker. Structures and Dynamics Labora-tory. N91-13766

This report presents the correlation of thestatic loads testing and finite element modelingfor the fiberglass pedestal used on theAtmospheric Emission Photometric Imaging(AEPI) experiment. This payload is to belaunched in the space shuttle as part of theATLAS-1 experiment. Strain gauge data fromrosettes around the highly loaded base arecompared to the same load case run for theSpacelab 1 testing done in 1981. Correlation ofthe model and test data was accomplishedthrough comparison of the composite stressinvariant utilizing the expected flight loads forthe ATLAS-1 mission. Where appropriate, theTsai-Wu failure criteria was utilized in thedevelopment of the key margins of safety.Margins of safety are all positive for the pedestaland are reported,

TM-103516 September 1990Coaligned Observations of Solar MagneticFields 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, SpaceScience Laboratory. N91-10832

This document constitutes the final report forMSFC Center Director's Discretionary FundProject Number 88-10. The objective of thisprogram was to develop the capability for obtain-ing cotemporal and coaligned observations of thestructure and evolution of the Sun's magneticfield at two different heights in the solaratmosphere: the photosphere, which is thelowest region observable with optical tele-scopes, and the chromosphere, which lies justabove the photosphere and is a region where themagnetic field dominates the gas motions so thata well-ordered structure governed by the field isobserved. By obtaining this three-dimensionalpicture of the solar magnetic field, we candevelop a better understanding of the magneticforces that produce and control the dynamic,high-energy phenomena occurring in the solaratmosphere that can affect the entire helio-sphere, including our own terrestrial environ-ment.

TM-103517 October 1990An Improved Exploratory Search Techniquefor Pure Integer Linear ProgrammingProblems. F.R. Fogle. Systems Analysis andIntegration Laboratory. N91-13910

This report documents the development of aheuristic procedure for the solution of pureinteger linear programming problems. The proce-dure draws its methodology from the ideas of theHooke and Jeeves type I and type II exploratorysearches, greedy procedures, and neighborhoodsearches. It utilizes an efficient rounding pro-cedure to obtain its first feasible integer pointfrom the optimal continuous solution obtained viathe simplex method.

Since this procedure is based entirely onsimple addition or subtraction of one to eachvariable of a point in n-space and the subsequentcomparison of candidate solutions to a given setof constraints, it facilitates significant complexityimprovements over existing techniques. It alsoobtains the same optimal solution found by thebranch-and-bound technique in 44 out of 45small to moderate size test problems. Twoexample problems are worked in detail toshow the inner workings of the procedure.


Furthermore, using an established weightedscheme for comparing computational effortinvolved in an algorithm, a comparison of thisalgorithm is made to the more established andrigorous branch-and-bound method. A computerimplementation of the procedure, in PC-compatible Pascal, is also presented anddiscussed. This procedure for finding optimalsolutions to integer-type problems may beapplied to various systems engineeringsituations in the conceptual, preliminary, anddetail design phases of the system developmentcycle.

TM-103518 November 1990Dendritic Morphology and Microsegregationin Directionally Solidified Superalloy, PWA-1480, Single Crystal: Effect of Gravity-Center Director's Discretionary Fund Report.S.N. Tewari, M.V. Kumar, I.E. Lee, and P.A.Curreri. Materials and Processes Labora-tory. N91-15391

Primary dendrite spacings, secondary den-drite spacings, and microsegregation have beenexamined in PWA-1480 single crystal speci-mens which were directionally solidified duringparabolic maneuvers on the KC-135 aircraft.Experimentally observed growth rate andthermal gradient dependence of primary dendritespacings are in good agreement with predictionsfrom dendrite growth models for binary alloys.Secondary dendrite coarsening kinetics show areasonable fit with the predictions from ananalytical model proposed by Kirkwood for abinary alloy. The partition coefficients oftantalum, titanium, and aluminum are observedto be less than unity; while that for tungsten andcobalt are greater than unity. This is qualitativelysimilar to their nickel base binaries. Micro-segregation profiles experimentally observed forPWA-1480 superalloy show a good fit withBower, Brody, and Flemings models developedfor binary alloys. Transitions in gravity levels donot appear to affect primary dendrite spacings. Atrend of decreased secondary arm spacings withtransition from high gravity to the low gravityperiod was observed at a growth speed of 0.023cm s~l. However, definite conclusions can onlybe drawn by experiments at lower growthspeeds which make it possible to examine theside-branch coarsening kinetics over a longerduration. Such experiments, not possible due to

the insufficient low-gravity time of the KC-135,may be carried out in the low-gravityenvironment of space.

TM-103519 October 1990Engineering Design Based on Risk—AnAlternate Criterion to the Engineering SafetyFactor. D.R. Moore. Materials and Pro-cesses Laboratory. X91 -10073

The design of engineering structures can bebased on risk when enough information about thestructure is available. This report comparesdesigning by risk to the more commonly usedapproach of designing by an engineering factor ofsafety. The safety factor concept of providingstructural assurance is challenged within thisreport. New methods are developed to assist indetermining structural risk in an engineeringdesign when the design is based on the inter-ference of two normally distributed engineeringphenomena. The risk factor (Rp) approach isoffered as an alternate method of establishingengineering design criteria. The engineering riskequation is developed which allows a simpledetermination of risk when coefficients of varia-tion are known. Several curves were developedthat relate Rp to coefficients of variation forvarious reliabilities. The author concluded thatdesigns and redesigns should be based on riskwhenever possible.

TM-103521 November 1990Predicting Thunderstorm Evolution UsingGround-Based Lightning Detection Net-works. Steven J. Goodman. Space ScienceLaboratory. N91-15660

Lightning measurements acquired principallyby a ground-based network of magnetic directionfinders are used to diagnose and predict theexistence, temporal evolution, and decay ofthunderstorms over a wide range of space andtime scales extending over four orders ofmagnitude. The nonlinear growth and decay ofthunderstorms and their accompanying cloud-to-ground lightning activity is described by the threeparameter logistic growth model. The growthrate is shown to be a function of the storm sizeand duration, and the limiting value of the totallightning activity is related to the availableenergy in the environment. A new technique isdescribed for removing systematic bearing errorsfrom direction finder data where radar echoes areused to constrain site error correction andoptimization (best point estimate) algorithms. Anearest neighbor pattern recognition algorithm isemployed to cluster the discrete lightning dis-charges into storm cells, and the advantages andlimitations of different clustering strategies forstorm identification and tracking are examined.

TM103522 November 1990The Rotating Spectrometer: New Biotech-nology for Cell Separations. David A. Noeverand Helen C. Matsos. Space Science Lab-oratory. N91-15673

An instrument for biochemical studies, calledthe rotating spectrometer, separates previouslyinseparable cell cultures. The rotating spec-trometer is intended for use in pharmacologicalstudies which require fractional splitting ofheterogeneous cell cultures based on cell mor-phology and swimming behavior. As a method toseparate and concentrate cells in free solution,the rotating method requires active organismparticipation and can effectively split the largeclass of organisms known to form spontaneouspatterns. Examples include the biochemical"star," an organism called Tetrahymenapyriformis. Following focusing in a rotated frame,the separation is accomplished using differentradial dependencies of concentrated algal andprotozoan species. The focusing itself appears asconcentric rings and arises from the coupling

between swimming direction and Coriolis forces.A dense cut is taken at varying radii andextraction is replenished at an inlet. Unlikestandard separation and concentrating tech-niques such as filtration or centrifugation, theinstrument is able to separate motile fromimmotile fractions. For a single pass, typical splitefficiencies can reach 200 to 300 percent com-pared to the inlet concentration.

TM-103523 November 1990A Biosensor for Cadmium Based on Biocon-vective Patterns. David A. Noever andHelen C. Matsos. Space Science Laboratory.

N91-15674r

An in vitro method for monitoring cadmium,one of the most lethal bivalent heavy metals, candetect biologically active levels. The effects ofcadmium tend to concentrate in protozoa farabove natural levels and therein begin trans-ferring through freshwater food chains to animalsand humans. In a small sample volume (~5 ml)the method uses the toxic response to the proto-zoa, Tetrahymena pyriformis, to cadmium. Theassay relies on macroscopic bioconvectivepatterns to measure the toxic response, giving asensitivity better than 1 u.g/1 and a toxicitythreshold to 7 ug/1 for Cd+2. Cadmium hinderspattern formation in a dose-dependent manner.Arrested organism growth arises from sloweddivision and mutation to nondividing classes.Unlike previous efforts, this method can be per-formed in a shallow flow device and does notrequire electronic or chemical analyses tomonitor toxicity.

TM-103524 January 1991An Evaluation of Bearings Operating in aCryogenic Environment With Silicon NitrideRolling Elements, H.G. Gibson. Materialsand Processes Laboratory. N91 -18436

The bearings used in the space shuttle mainengine (SSME) high pressure oxidizer turbo-pump (HPOTP) do not meet the expected lifegoals that were set for them. In an effort toimprove their performance, many solutions arebeing studied. New bearing materials are beingdeveloped, better manufacturing techniques arebeing investigated, and improved cage materialsfor better lubrication are being tested. This reportfocuses on the replacement of steel balls with


ones made of silicon nitride in 57-mm HPOTPbearings. The bearings were then installed in atest rig and run at near turbopump operatingconditions. The results from this test series havebeen encouraging, with silicon nitride showinggood wear resistance and thermal stability.

TM-103525 November 1990Atmospheric 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 selectedatmospheric conditions observed near spaceshuttle STS-41 launch time on October 6, 1990,at Kennedy Space Center, Florida. Values ofambient pressure, temperature, moisture, groundwinds, visual observations (cloud), and windsaloft are included. The sequence of prelaunchJimsphere-measured vertical wind profiles isgiven in this report. The final atmospheric tape,which consists of wind and thermodynamicparameters versus altitude, for STS-41 vehicleascent has been constructed. The STS-41 ascentatmospheric data tape has been constructed byMarshall Space Flight Center's Earth Scienceand Applications Division to provide aninternally consistent data set for use in postflightperformance assessments and represents thebest estimate of the launch environment to the400,000-ft altitude that was traversed by theSTS-41 vehicle.

TM-103526 February 1991A Damage Tolerance Comparison ofIM7/8551 and IM8G/8553 Carbon/EpoxyComposites. D.G. Lance and A.T. Nettles.Materials and Processes Laboratory.

N91-18222

A damage tolerance study of two newtoughened carbon fiber/epoxy resin systems wasundertaken as a continuation of ongoing workinto screening new opposites for resistance toforeign object impact. This report is intended tobe a supplement to NASA TP 3029 in which fournew fiber/resin systems were tested for damagetolerance. Instrumented drop weight impacttesting was used to inflict damage to 16-plyquasi-isotropic specimens. Instrumented outputdata and cross-sectional examination of thedamage zone were utilized to quantify thedamage. It was found that the two fiber/resin

systems tested in this study were much moreimpact resistant than an untoughened compositesuch as T300/934, but were not as impact resis-tant as other materials previously studied.

TM-103527 March 1991Evaluation of Bearing Configurations Usingthe Single Bearing Tester in Liquid Nitrogen.T. Jett, P. Hall, and R. Thorn. Materials andProcesses Laboratory. N91-21532

Various bearing configurations were testedusing the Marshall Space Flight Center singlebearing tester with LN2 as the cryogenic coolant.The baseline was one Rocketdyne phase I highpressure oxidizer turbopump (HPOTP) pump end45-mm bore bearing. The bearing configurationsthat were tested included a Salox/M cage con-figuration, a silicon nitride ball configuration, anelongated cage configuration, and a Bray 601grease configuration.

TM-103528 February 1991GEOSIM—A Numerical Model for Geo-physical Fluid Flow Simulation. Karen A.Butler, Timothy L. Miller, and Huei-Iin Lu.Space Science Laboratory. N91-21450

A numerical model which simulates geo-physical fluid flow in a wide range of problems isdescribed in detail, and comparisons of some ofthe model's results are made with previousexperimental and numerical studies. The modelis based upon the Boussinesq Navier-Stokesequations in spherical coordinates, which can bereduced to a cylindrical system when latitudinalwalls are used near the pole and the ratio oflatitudinal length to the radius of the sphere issmall. The equations are approximated by finitedifferences in the meridional plane and spectraldecomposition in the azimuthal direction. Theuser can specify a variety of boundary and initialconditions, and there are five different spectraltruncation options. The results of five validationcases are presented: (1) the transition betweenaxisymmetric flow and baroclinic wave flow inthe side-heated annulus; (2) the steady baro-clinic wave of the side-heated annulus; (3) thewave-amplitude vacillation of the side-heatedannulus; (4) transition to baroclinic wave flow ina bottom-heated annulus; and (5) the SpacelabGeophysical Fluid Flow Cell (spherical)experiment.


TM-103529 March 1991An Evaluation of GTAW-P Versus GTAWelding of Alloy 718. W.R. Gamwell, C.Kurgan, and T.W. Malone. Materials andProcesses Laboratory. N91-21287

Mechanical properties have been evaluatedto determine statistically whether the pulsedcurrent gas tungsten arc welding (GTAW-P)process produces welds in alloy 718 with roomtemperature structural performance equivalent tocurrent space shuttle main engine (SSME)welds manufactured by the constant current gastungsten arc welding (GTAW) process.Evaluations were conducted on two base metallots, two filler metal lots, two heat input levels,and two welding processes. The material formwas 0.125-inch (3.175-mm) alloy 718 sheet.Prior to welding, sheets were heat treated toeither the ST or STA-1 condition. After welding,panels were left as welded or heat treated to theSTA-1 condition, and weld beads were left intactor machined flush. Statistical analyses wereperformed on yield strength (YS), ultimate ten-sile strength (UTS), and high cycle fatigue(HCF) properties for all the post weldedmaterial conditions. Analyses of variance(ANOVA) were performed on the data todetermine if there were any significant effects onUTS or HCF life due to variations in base metal,filler metal, heat input level, or welding process.

Statistical analyses have shown that theGTAW-P process does produce welds withroom temperature structural performanceequivalent to current SSME welds manufacturedby the GTAW process, regardless of priormaterial condition or post welding condition.

TM-103530 February 1991Atmospheric Environment for Space Shuttle(STS-38) Launch. G.L. Jasper and G.W.Batts. Space Science Laboratory.

N91-21633

This report presents a summary of selectedatmospheric conditions observed near spaceshuttle STS-38 launch time on November 15,1990, at Kennedy Space Center, Florida. STS-38carried a Department of Defense payload and theflight azimuth in this report will be denoted by areference flight azimuth, since the actual flightazimuth is not known. Values of ambient pres-sure, temperature, moisture, ground winds,visual observations (cloud), and winds aloft are

Welded joints are an essential part ofpressure vessels such as the space shuttle mainengine (SSME) turbopumps. Defects produced inthe welding process can be detrimental to weldperformance. Recently, review of the SSME highpressure fuel turbopump (HPFTP) titanium inletx rays revealed several weld discrepancies suchas penetrameter density issues, film processingdiscrepancies, weld width discrepancies,porosity, lack of fusion, and weld offsets.Currently, the sensitivity of welded structures todefects is of concern. From a fatigue standpoint,weld offset may have a serious effect since localyielding, in general, aggravates cyclic stresseffects. Therefore, the weld offset issue is con-sidered in this report. Using the finite elementmethod and mathematical formulations, para-metric studies were conducted to determine theinfluence of weld offsets and a variation of weldwidths in longitudinally welded cylindricalstructures with equal wall thicknesses on bothsides of the joint. From the study, the finite ele-ment results and theoretical solutions are pre-sented.

TM-103535 April 1991Effects of Water on the Strength of Zerodur.D. Tucker and A. Setzer. Materials andProcesses Laboratory. N91-24430

An experimental design matrix was con-structed to determine the effects of time andtemperature water soak on the strength ofZerodur glass-ceramic. It was found thatstrength does increase in a nonlinear mannerwhich is consistent with existing theories ofcrack tip blunting and residual stress reduction.

TM-103536 May 1991Effect of Flange Bolt Preload on SpaceShuttle Main Engine High Pressure OxidizerTurbopump Housing Analysis. J.B. Min, L.M.Johnston, and B. Czekalski. Structures andDynamics Laboratory. N91-245 84

Cracks at the seal fillet flange and the strutpilot groove of primary turbine drain passage ofthe space shuttle main engine (SSME) highpressure oxidizer turbopump (HPOTP) havebeen observed and reported. Stress informationfor critical structural components in the SSMEunder actual conditions is necessary for designand life prediction analysis. However, littleinformation is available about the stress distri-bution at this location under various combina-tions of loadings and environments. Thus, astress analysis was conducted to determine aninfluence of the various operation and installationloads on the stresses of the HPOTP mainmounting flange. To do this, a three-dimensional(3-D) finite element model of the HPOTP hous-ing was generated. A fairly comfortable margin ofstresses at the flange fillet with respect to theyield stress of Inconel 718 is shown in thisanalysis. However, it was revealed that thebending stress arising from the housing flangebolt preloads could significantly affect the stressdistribution at the strut pilot groove of primaryturbine drain passage in the HPOTP housing.Consequently, the information obtained from thepresent 3-D analysis results should be useful inguiding the development of the SSME HPOTP.

TM-103537 May 1991The Effect of Stress on Hydrogen Uptake andDesorption by A-286. M.D. Danford.

. Materials and Processes Laboratory.N91-28341


The uptake and desorption of hydrogen byA-286 as a function of stress has been studiedusing electrochemical methods. It was found thatthe apparent surface hydrogen concentration C0,the mean hydrogen concentration C, and thehydrogen distribution uniformity all increased upto a stress level 50-percent of yield anddecreased thereafter. The value of the hydrogendiffusion coefficient D was relatively unaffectedby stress while the percent of trapped hydrogenappeared to decrease with increasing stress.

TM-103539 April 1991Analysis of Lightning Field ChangesProduced by Florida Thunderstorms. W.J.Koshak. Space Science Laboratory.

N91-25555

A new method is introduced for inferring thecharges deposited in a lightning flash. Previousnonlinear least-squares methods have usedsimple point charge (Q) and point dipole (P)models to describe ground-based observationsof lightning-caused field changes (AFs). In thenew approach, the AE's are described by a moregeneral volume charge distribution that is definedon a large cartesian grid system centered above

the measuring network. We show that a linearsystem of equations can be used to relate theAE's at the ground to the values of charge on thisgrid. With this approach, it is possible to applymore general physical constraints to the chargesolutions, and it is possible to access theinformation content of the AE data. Computer-simulated AE inversions show that the locationand symmetry of the charge retrievals areusually consistent with the known test sources.Analyses of three natural lightning events showthat the linear method provides sourcedistributions that are in reasonable agreementwith Q- and P-model results.

TM-103540 June 1991The Corrosion Protection of 2219-T87Aluminum by Anodizing. M.D. Danford.Materials and Processes Laboratory.

N91-26312

Various types of anodized coatings havebeen studied for 2219-T87 aluminum. Theseinclude both type II and type III anodize coatswhich have been water sealed and a newlydeveloped and proprietary Magnaplate HCR™coat. Results indicate that type III anodizing isnot much superior to type II anodizing as far ascorrosion protection for 2219-T87 aluminum isconcerned. Magnaplate HCR™ coatings shouldprovide superior corrosion protection over anextended period of time using a coating thicknessof 51 microns (2.0 mils).

TM-103541 June 1991Illuminance and Luminance Distributions of aPrototype Ambient Illumination System forSpace Station Freedom. R.C. Mullican andB.C. Hayes. Mission Operations Laboratory.

N91-26193

Preliminary results of research conducted inthe late 1970's indicate that perceptual qualitiesof an enclosure can be influenced by the distribu-tion of illumination within the enclosure.Subjective impressions such as spaciousness,perceptual clarity, and relaxation or tenseness,among others, appear to be related to differentcombinations of surface luminance. A prototypeindirect ambient illumination system wasdeveloped which will allow crew members toalter surface luminance distributions within anenclosed module, thus modifying perceptual cuesto match crew preferences. A traditional lensed


direct lightning system was compared to theprototype utilizing the full-scale mockup of SpaceStation Freedom developed by Marshall SpaceFlight Center. The direct lensed system wasinstalled in the habitation module with theindirect prototype deployed in the U.S. laboratorymodule. Analysis centered on the illuminanceand luminance distributions resultant from thesesystems and the implications of variousluminaire spacing options. All test configurationswere evaluated for compliance with NASAStandard 3000, "Man-System IntegrationStandards."

N91-27330

A vapor deposition process has been definedthrough a spinoff effort of space weldingdevelopment. In this development for welding ina space environment, a hollow electrode wasused to add gas precisely at the welding arc.This provides gas for ionization which carries thewelding arc current. During this weldingdevelopment metal vapor coatings wereobserved. These coatings are unique in that theyare produced by a new process. This reportcharacterizes some coatings produced and thepotential of this new and innovative vapordeposition process. Advantages over prior artare discussed.

angle-of-attack variation for control. Theseapplications are: return from geosynchronous orlunar orbit to low Earth orbit and planetary aero-capture at Earth and Mars. A number of aero-brake design considerations are reviewed. It wasfound that the flow impingement behind theaerobrake and the aerodynamic heating loads arethe primary factors that control the sizing of anaerobrake. The heating loads and other loads,such as maximum acceleration, are determinedby the vehicle ballistic coefficient, theatmosphere entry conditions, and the trajectorydesign. Several formulations for defining an opti-mum trajectory are reviewed, and the variousperformance indices that can be used are evalu-ated. The "nearly grazing" optimal trajectorywas found to provide the best compromisebetween the often conflicting goals of minimizingthe vehicle propulsive requirements and min-imizing vehicle loads. The relationship betweenvehicle and trajectory design is investigated fur-ther using the results of numerical simulations oftrajectories for each aerobrake application. Thedata show the sensitivity of the trajectories toseveral vehicle parameters and atmosphericdensity variations. The results of the trajectoryanalysis show that low lift to drag ratio aero-brakes, which use angle-of-attack variationfor control, can potentially be used for a widerange of aerobrake applications.

TM-103546 July 1991BATSE-GRO Observations of Bremsstrah-lung from Electron Precipitation Events. J.M.Horack and G.J. Fishman. Space ScienceLaboratory.

The Burst and Transient Source Experiment(BATSE) on the Gamma Ray Observatory(GRO) has detected a large number of terrestrialelectron precipitation events. Bremsstrahlung isgenerated as the precipitating electrons interactin the atmosphere, or at the spacecraft, and thisradiation is detected by the gamma ray detectorsonboard. Several examples of such events arepresented here, and the different classes ofevents are described. A correlation of events tostrong magnetospheric activity is presented, andthe association of a subset of events to apowerful VLF transmitter on the western coastof Australia is described.

This report investigates several applicationsof low lift to drag ratio aerobrakes which use

NASA has recently completed a shuttle-borne stellar ultraviolet astronomy missionknown as Astro-1. A three-axis instrumentpointing system (IPS) was employed to accu-rately point the science instruments. In order toanalyze the pointing control system and verifypointing performance, a simulation of the IPS hasbeen developed using the multibody dynamicssoftware TREETOPS. The TREETOPS IPSsimulation is capable of accurately modeling themultibody IPS system undergoing large angle,nonlinear motion. This report documents thesimulation and presents example casesdemonstrating disturbance rejection, fine pointingoperations, and multiple target pointing andslewing of the IPS.

TM-103548 July 1991STS-35 Scrub 3 Hydrogen Leak Analysis. D.Seymour. Propulsion Laboratory.

During the summer of 1990, space shuttleColumbia experienced both an externaltank/orbiter disconnect hydrogen leak and mul-tiple internal aft compartment hydrogen leaks.After the third scrub of STS-35, a leak investi-gation team was organized. In support of thisteam, an analysis of the data obtained duringscrub 3 was performed. Based on this analysis,the engine 2 prevalve was concluded to be themost likely leak location and to account for mostof the observed leakage.

Corrosion evaluation studies were conductedon chemical conversion coated and anodized7075-T73 and 2219-T87 aluminum alloys. Thecorrosive environments ranged from a 95-percentrelative humidity combined with 35 °C (95 °F) toa 5-percent salt fog environment at 35 °C(95 °F). An evaluation of the effect of tempera-ture on corrosion protection and adhesion prop-

erties was conducted by exposing test samplesto various temperatures for specified timeperiods followed by environmental exposure andadhesion testing.

TM-103550 July 1991Empirical Predictions of HypervelocityImpact Damage to the Space Station. W.K.Rule and K.B. Hayashida. Structures andDynamics Laboratory.

This report describes a family of user-friendly, DOS PC based, Microsoft BASIC pro-grams written to provide spacecraft designerswith empirical predictions of space debrisdamage to orbiting spacecraft. The spacecraftwall configuration is assumed to consist ofmultilayer insulation (MLI) placed between aWhipple style bumper and the pressure wall.Predictions are based on data sets of experi-mental results obtained from simulating debrisimpacts on spacecraft using light gas guns onEarth. A module of the program facilitates thecreation of the data base of experimental resultsthat are used by the damage prediction modulesof the code. The user has the choice of threedifferent prediction modules to predict damage tothe bumper, the MLI, and the pressure wall. Oneprediction module is based on fitting low orderpolynomials through subsets of the experimentaldata. Another prediction module fits functionsbased on nondimensional parameters through thedata. The last prediction technique is a uniqueapproach that is based on weighting theexperimental data according to the distance fromthe design point.

TM-103551 July 1991Electrodeposited Zinc-Nickel as an Alter-native to Cadmium Plating for AerospaceApplication. V.C. McMillan. Materials andProcesses Laboratory.

Corrosion evaluation studies were conductedon 4130 alloy steel samples coated with elec-trodeposited zinc-nickel and samples coatedwith electrodeposited cadmium. The zinc-nickelwas deposited by the selection electrochemicalmetallizing process. These coated samples wereexposed to a 5-percent salt fog environment at35±2 °C (95±5 °F). The exposure period rangedfrom 96 to 240 hours. An evaluation of the effectof dichromate coatings on the performance ofeach plating was conducted. The protection


afforded by platings with a dichromate seal wascompared to platings without the seal. Duringthe later stages of testing, deposit adhesion andpotential for hydrogen entrapment were alsoevaluated.

TM-103552 August 1991Multiplexing Readout Channels in Propor-tional Counters. J. Caristi. Space ScienceLaboratory.

Proportional counters are important instru-ments used in sensing "hard" x rays. Thisdocument describes the possibility of doublingthe number of readout channels in the detectorwithout increasing the electronics needed toamplify channel signals. This suggests that itshould be possible, conversely, to reduce thenumber of amplifiers, thereby reducing the weightand energy budget of the instrument. Variousnumerical multiplexing schemes are analyzed,and a computer program is presented that canreconstruct multiplexed channel outputs withvery good accuracy.

In an effort to best utilize all areas of exper-tise within the Materials and ProcessesLaboratory, a Composite Materials Charac-terization Task Team was developed to helpbring together the various branches within theLaboratory to develop a comprehensive database on composite materials. A "test run" wasperformed on IM6/3501-6 carbon/epoxy in whichthe material was processed, machined intospecimens, and tested for damage tolerancecapabilities. Nondestructive test data played amajor role in this element of composite charac-terization. A time chart was produced showingthe time the composite material spent withineach Branch or Division in order to identify thoseareas which produce a long turnaround time.Instrumented drop weight testing was performedon the specimens with nondestructive evaluation(NDE) being performed before and after theimpacts. Destructive testing in the form of cross-

sectional photomicrography and compression-after-impact (CAI) testing were used. Resultsshow that the processing and machining stepsneeded to be performed more rapidly if data on acomposite material is to be collected within areasonable timeframe. The results of the damagetolerance testing showed that IM6/3501-6 is abrittle material that is very susceptible to impactdamage.

N91-26654

A new (1990) version of the NASA/MSFCGlobal Reference Atmospheric Model (GRAM-90) is presented and discussed. GRAM-90incorporates extensive new data, mostlycollected under the Middle Atmosphere Program(MAP), to produce a completely revised middleatmosphere model (20 to 120 km). Because ofearlier data sparseness in this altitude region,previous versions of GRAM relied on a 6-monthdisplacement of Northern Hemisphere data torepresent the Southern Hemisphere. GRAM-90alleviates this shortcoming by utilizing actualdata from the Southern Hemisphere for eachmonth. The NASA Marshall EngineeringThermosphere (MET) model has also beenincorporated into the GRAM-90 program, at allorbital altitudes greater than 120 km. Part I ofthis report serves as a technical description ofthe GRAM-90 program, with extensive docu-mentation on the program operation and usage.Sample results are presented, in the form ofheight-latitude and latitude-longitude plots.Comparisons are made between the empiricallybased GRAM-90 model and results from a "firstprinciples" stratospheric circulation model(SCM) in the 20- to 80-km height region.Specific areas of improvement of GRAM-90 overthe earlier GRAM model results are also noted.A test case example is also included. Part n ofthis report presents the entire GRAM-90 pro-gram listing along with the major data base list-ings.

TM-4289 May 1991Atmospheric Turbulence Review of SpaceShuttle Launches. M. Susko. Space SciencesLaboratory. N91-23215

The primary objective of this paper is toreport on the research and analysis on identifyingturbulent regions from the surface to 16 km forspace shuttle launches. This research hasdemonstrated that the results from the FPS-16radar/jimsphere balloon system in measuringwinds can indeed indicate the presence or con-ditions ripe for turbulence in the troposphere andlower stratosphere. It is further demonstratedthat atmospheric data obtained during the shuttlelaunches by the rawinsonde in conjunction withthe jimsphere provides the necessary meteoro-

logical data to compute aerodynamic parametersto identify turbulence, such as Reynolds number,drag coefficient, turbulent stresses, total energy,stability parameter, vertical gradient of kineticenergy, Richardson number, and the turbulenceprobability index. There is no magic fool-proofcriteria in atmospheric turbulent probability ofoccurrence. However, enhanced temperaturelapse rates and inversion rates, strong vectorwind shears, and large changes in wind directionidentify the occurrence of turbulence at thetropopause. When any two of the above condi-tions occur simultaneously, a significant proba-bility of turbulence can occur as shown in thispaper.

PLT is a high level plotting package. AProgrammer can create a default plot suited forthe data being displayed. At run times, users canthen interact with the plot overriding any or all ofthese defaults. The user is also provided thecapability to fit functions to the displayed data.This ability to display, interact with, and to fit thedata make PLT a useful tool in the analysis ofdata. The Quick and Dandy Plotter (QDP) pro-gram will read ASCII text files that contain PLTcommands and data. Thus, QDP provides aneasy way to use the PLT software. QDP filesprovide a convenient way to exchange data. TheQDP/PLT software is written in standardFortran 77 and has been ported to VAX VMS,SUN UNIX, IBM AIX, NeXT NextStep, andMS-DOS systems.

TP-3066 November 1990Electrochemical Studies of Corrosion In-hibitors. M.D. Danford. Materials and Pro-cesses Laboratory. N91-17208

The effect of single salts, as well as multi-component mixtures, on corrosion inhibition hasbeen studied for type 1010 steel; for 5052,1100,and 2219-T87 aluminum alloys; and for copper.Molybdate-containing inhibitors exhibit animmediate, positive effect for steel corrosion, butan incubation period may be required foraluminum before the effect of a given inhibitor canbe determined. The absence of oxygen was foundto provide a positive effect (smaller corrosionrate) for steel and copper, but a negative effectfor aluminum. This is attributed to the twopossible mechanisms by which aluminum canoxidize. Corrosion inhibition is generally similarfor oxygen-rich and oxygen-free environments.The results of this study show that the elec-trochemical method is an effective means ofscreening inhibitors for the corrosion of singlemetals, with caution to be exercised in the caseof aluminum.

TP-3075 January 1991Plate and Butt-Weld Stresses Beyond Elas-tic Limit, Material and Structural Modeling.V. Verderaime. Space Science Laboratory.

N91-16413

Ultimate safety factors of high performancestructures depend on stress behavior beyond theelastic limit—a region not too well understood.An analytical modeling approach was developedto gain fundamental insights into inelasticresponses of simple structural elements.Nonlinear material properties were expressed inengineering stresses and strains variables andcombined with strength of material stress andstrain equations similar to numerical piece-wiselinear method. Integrations are continuous whichallows for more detailed solutions. Included withinteresting results are the classical combinedaxial tension and bending load model and thestrain gauge conversion to stress beyond theelastic limit. Material discontinuity stress factorsin butt-welds were derived. This is a working-type document with analytical methods andresults applicable to all industries of high relia-bility structures.

TP-3108 March 1991A Novel Method of Testing the ShearStrength of Thick Honeycomb Composites.A.J. Hodge and A.T. Nettles. Materials andProcesses Laboratory. N91-21242

Sandwich composites of aluminum andglass/phenolic honeycomb core were tested forshear strength before and after impact damage.The assessment of shear strength was per-formed in two ways; by four-point bend testing ofsandwich beams and by a novel "double lapshear" (DLS) test. This novel testing techniquewas developed so smaller specimens could beused thus making the use of common laboratoryscale fabrication and testing possible. The twotechniques yielded similar data. The DLS testgave slightly lower shear strength values of thetwo methods but were closer to the supplier'svalues for shear strength.

TP-3123 June 1991A Scheme for Bandpass Filtering Magne-tometer Measurements to ReconstructTethered Satellite Skiprope Motion. M.E.Polites. Structures and Dynamics Labora-tory. N91-25629

This paper presents a unique scheme forreconstructing tethered satellite skiprope motionby ground processing of satellite magnetometermeasurements. The measurements are modifiedbased on ground knowledge of the Earth'smagnetic field and passed through bandpassfilters tuned to the skiprope frequency.Simulation results are presented which verify thescheme and show it to be quite robust. The con-cept is not just limited to tethered satellites.Indeed, it can be applied wherever there is aneed to reconstruct the coning motion of a bodyabout a known axis, given measurements of aknown vector in body-fixed axes.

TP-3128 August 1991The Interaction of Hydrogen With MetalAlloys. M.D. Danford and J.W. Montano.Materials and Processes Laboratory.

N91-29318

Hydrogen diffusion coefficients have beenmeasured for several alloys, and these havebeen determined to be about the same at 25 °Cfor all alloys investigated. The relation of struc-ture, both metallurgical and crystallographic, to

12


the observed hydrogen distribution on charginghas been investigated, as well as the role ofhydride formation in the hydrogen resistance ofmetal alloys. An attempt has been made tocorrelate the structures and compositions ofmetals alloys as well as other parameters withthe ratios of their notched tensile strengths inhydrogen to that in helium, R(H2/He), which arebelieved to represent a measure of theirhydrogen resistance. Evidence supports thebelief that hydrogen permeability and hydrogenresistance are increased by smaller grain sizesfor a given alloy composition.

brief explanation is given along with graphs toillustrate the application of the envelopes to thepower and crew resources. The benefits andcosts of each method are analyzed in terms ofresource utilization. In addition to the effect onindividual activities, resource envelopes areanalyzed at the experiment level.

TP-3148 September 1991Stress Corrosion Study of Carburized AISI9310 and Carburized M-50 NiL Steels. P.O.Torres. Materials and Processes Laboratory.

A stress corrosion cracking (SCC) evalua-tion of Carburized AISI 9310 and Carburized M-50 NiL steels was undertaken. AISI 9310 is acandidate substitute to 440C for the bearinginner race in the space shuttle main enginealternate turbopump development program, andM-50 NiL may also find applications as a bear-ing alloy. Round tensile specimens of thesealloys at several stress levels, as well as corro-sion samples of AISI 9310, were exposed to100-percent relative humidity at 38 °C (100 °F).The maximum tensile stresses that produced noSCC failures in 1 year of exposure were 172 MPa(25 ksi) for AISI 9310 and 345 MPa (50 ksi) forM-50 NiL. Each AISI 9310 steel fractureshowed a circumferential crack between the caseand the core. Both alloys developed rust on thesurface and pitting; however, AISI 9310 rusted toa greater extent than M-50 NiL. Thin, densechrome (TDC) was also evaluated in this pro-gram as a corrosion barrier alternative; however,its protection was minimal. Corrosion spotsvisible to the naked eye appeared in less than 5days of exposure. Although TDC plating on testspecimens prevented the intensive corrosionattack which occurred in bare samples after along time exposure, the TDC plating did not offersufficient protection to avoid failures. The resultsobtained in this evaluation must be carefullyconsidered when designing bearing componentsmade of these materials.

TP-3161 September 1991Automating a Spacecraft Electrical PowerSystem Using Expert Systems. L.F. Lollar.Information and Electronic Systems Labora-tory.

Since Skylab, Marshall Space Flight Center(MSFC) has recognized the need for large elec-trical power systems (EPS's) in upcoming

13


spacecraft. The operation of the spacecraftdepends on the EPS. Therefore, it must be effi-cient, safe, and reliable. In 1978, as a conse-quence of having to supply a large number of EPSpersonnel to monitor and control Skylab, theElectrical Power Branch of MSFC began theautonomously managed power system (AMPS)project. This project resulted in the assembly of a25-kW high-voltage dc test facility and providedthe means of getting man out of the loop as muchas possible. AMPS includes several embeddedcontrollers which allow a significant level ofautonomous operation. More recently, the

Electrical Division at MSFC has developed thespace station module power management anddistribution (SSM/PMAD) breadboard toinvestigate managing and distributing power inthe Space Station Freedom habitation andlaboratory modules. Again, the requirement for ahigh level of autonomy for efficient operation overthe lifetime of the station and for the benefits ofenhanced safety has been demonstrated. Thispaper describes the two breadboards and thehierarchical approach to automation which wasdeveloped through these projects.
