5 IBLIOGRAPHY OF LEWIS RESEARCH CENTER TECHNICAL PUBLl CATIONS ANNdUNCED I N 1978

Lewis Research Center Cleveland. Ohio 44135 May 1979

PREFACE

In 1978, the Lewis publications output was 213 research reports and 243 journal articles and conference presentations. The number of confiren* presentations (199) that were given at seminars and society symposiums was the high9st in the Centerts history. The production of 267 contractor reports increased 16 percent over that of 1977. In addition, 50 patent applications were filed and 35 patents issued,*

In 1977, the Lewis Director initiated the Annual Award for Best Lewi:; Publication. The purpose of ,,lie award is to encourage r ~ d reward outstanding research and tech- nology contriilutions by Lewis staff members. The criteria for selsction are quality and innovativeness, potential impact on the research and technology field, and the ex- cellence of the presentation. The publicatior date must be htween July 1 of the pre- ceding year and J m e 30 of the award year. The winning publication i s selected by the Lewis Research Advisory Board. The award is a framed certificate and $1000,

In 1977, the first year of the award, the Best Lewis Publication was "I!rotheymai Elastohydrodynamic Lubrication Point Contacts, Parts III and IVw by Bernard J. Hamrock and Duncan Dowson (TWs D-8317 and D-8318). They are described in Ab- stracts N77- 11400 (p. 111) and N76- 35509 (n. 89) of the YBibliography of L2wis Research Center Publications Announced in 197711 and the "Bibliography of Lewis Research Center Publications Announced in 1976, " respectively.

In 1978, the Annual Award for Best Lewis Publication was presented for the fol- lowing two papers: tlUnsteady Flow in a Supersonic Cascade with Strong In-Passage Shocksl'by Marvin E. Goldstein, Willis B r w , and J. J, Adarnczyk, which is described in Abstract A78-17270 (p. 6) and "Models for Some Aspects of Atmospheric Vortiz=es1l by Robert G. Deissler, which i s described in Abstract A78- 1458 1 (p. 150).

P11 the publications in this collection were anno'mced in the 1978 issues of STAR (Scientific and Technical Aerospace Reports) and/or IA A (hternational Aerospace Abstrzcts).

The arrangement of the matcrial i s by NASA svbject category, as noted in the Contents. The Lewis-authored items are listed first. followed by the contractor items. \Vithin each of these groups is listed report liter&% in N-number t equence, followed by the journd and conference preseatations, in A-number sequence.

The various indexes will help locate specific publications by s~hject , author, con- tractor organization, contract number, and report number.

Linaarized theory is used to study the unsteady flow In a supersonrc cascade with III pdsage shoc:; waves. We use the Wiener- Hopf technique to obtain a clored.form analytical solution for the wperranic regioo. To obtain a soli~tion for the rotat~onal flow in the subsonic region bve must solve an infinte set ol linear algebrc~c equations. The analysis show that i t is posslale to co~relatt. quantitatively the orcillatory shock motion wlth the Kuna conditiw at the tlailing edges of the blades. This feature al!ows us I n account for thc effect of shock motion on the stabllity o f thc iascade. Unlike the theory for a conipletelv supersonic flow, the present study predicts the occurrence of supersol~ii: L~el>d~ny flutter. It therefore provider a possible ehplanatton for the bendlng flutter that has recently been detected ill aircraftengine comp:essors at hlgher blade loadings. (Author)

A numatiral method of solution of tho lnviscid. comprwsible. two-dimenswnrl unsteady flow on a blade-to-blade stream surface through a stage (rotor and stator) or a slnglq blade row of an .axial now compreawr or fan is described. A cyclic procedure has been developed Snr repmsentatlon of adjacent Made-to.Made paasages which asymptotically achieves the correct phesa between all passages of a stage. A rhock-capturing finite difference method is employea in the interior of tho paasage, and a method of characteristics technique is used at the boundaries The Made sl~pstreams form two of the passpge bounderies and are treated as moving contact surfaces capable of s~pporting lumps in entropy and tangential velocrW~The Kutta conjrtron IS Imposed by raqurring the slipstreams to onginate at the tralllng edges. whtch are assumed to be sharp.

in the full order state space and thus elimineta any need for model reduction tachniqus. Using the potformonce measure and control structure of the MVCS program LOR d s i g , an equivalent OFR feedback control is obtained. The flexibility of the OFR as a control design procedure is dsmonstrated and differing feedback control structures are evaluated. (Author)

In order to understand the prqg8tion of broodband sound horn a device such as a jet engine, it is necewry to make fluctuating pressure measurements in the ducted airstream. However, in a flow:ng duct, fluctuat~ng pressure energy can be due to both turbulence and sound travelling in the duct. By using the principal that sound waves and turbulent flow pressure perturbations travel at different velocities. a probe has been dweloped thaI provides the data iecessary to separate the energy due to sound from that due to turbulence. A minisomprter based FFT analysis of the probe measurements provides the overall lwei of she broadband sound in the duct as well as the spectral distribution of the sound energy.

Linear optimd control theory is applied to the control synthesis of a high bypctrs ratio. variable pitch, turbofan engine. The basic control philosophy is to use only a low order dynamic model of the plant coupled with the concept of integral-r~tput states so as to maintain cmtrol simplicity yet guarantee integral control of thrust. turbine temperature and other important engine outputs. Lirwar simulation results indicate that the control system developed provides rapid control of small thrust perturbations and quickly elim~nates the effect of unmodrlled th~urt- and tamperature d~stur- bances. Large thrust accelerations are obtained in aboul one half second while the control maintains l~egligible overshoot in tempera. ture and stall margins. (Author)

In th~s paper, a failure detectioc aM correction strategy for turbofall engines is discussed. Th~s strategy allows continuihg control of the elgines In the event of a sensor failure. An extended Kalman filter is used to provide the best estimate of the state of the engltre bawd on currently available sensor outputs. Should a sensor failure occur the control IS based on the best estimate rather than the sensor oi~tput. The extended Kalman filter consists of essentially two parts, a notilinear model of the englne and update log~c which causes the model to track the actual engine. Details on the model and up-date logic :.e presented. To allow implerrenta:~on. spproximat~ons are made to tlie feedback gain matrlx which result In a slngle feedback matrix which is suitable for use over the entire fli@t envelop. The effect of these approx~mations on stability and response is dlrussed. Results from a detalled nonlinear simulation ~nd~cate that good control can be maintained even under mult~ple ta~lures.

I an engine diagnostics program which has the obiective to identify and quantih, the causes and sources of pe:formance deterioration in the JT9D turbofan engine and to develop basic data which will be applied to minimize performance degradation of current and future engines. Genrral areas where performance losses occur are examined, taking into account seals, blades and vanes, and cases. Potential performance improvement concepts are related to improved compo- nent aer~dynamics. improved flowpath sealing, blade tip clearance control, improved turhine cooling effectiveness, improved turbine materials and coatings. duct and nozzle aerodynamic refinemefits. nacelle aerodynamic refinements, forced exhaust mixers. advanced iucells mdterials, and advanced fuel control.

The resulting eftcctiw thermal conductivity was approximately ,00008 W;m-K for the MLI systems (IiquiZ h y d r w test results) and ,00054 Wlm-K for the LEI lystern (liquid nitrogen test results corrected to liquid hydr-n temperature). The f f i K ML i system experienced a rnaxmum thermal degradation of 38 percent, the DAM MLI system 14 percent. and the LEI system 6.7 percent due to repeated thermal cycling reprcgnting typical WWX flight condit;ons. Repeated exposure of the DAM MLI system to a hi* humidity environment for periods as long as 8 weeks provided a maximum degradation of only 24 percent. (Author)

A plannsd flight test of m 8 c m oiameter, electron- bombardment mercury ion thruster system is described. The primary objective of the test is to flipht qualify the 5 mN thruster systvn for auxiliary pa~pulsion applications. A seven year north.routh station. keeping mission was selected as the basis for the flight test opetatirq profile. The flight test, which will employ two thruster systems, will

I alu, generate thruster systeln space performdrra data, rnedsure thruster.spacecraft ~nteractions, and demonstrate thruster operation in a numLer o' operating modes. The flight test is desig2aed as SAMS0.601 and will be flown abo~rd the Shuttlo-launched Air Force Space Test Program P8Ol satellite In 1981. The spacecrah will be 3-axis stabllired in its final 740 k m cirnrlar orbit, which will have an ~nclination of at least 73dqreer The spacecraft design lifetime IS

The historical record of the SERT II spacecraft ;nd ion thruster systems for 8 years since the February 1970 lamch is reviewed. The original SERT II minion, one year duration, w s planned with the w m c r a f l i n r continuous sunl iM orbit to uovide cont imu: solar p o w . An extended mission, usinp intermittent power rvailable from en earth shadowed orbit has been p e r f o r d duing the past 5 years wh~le w i t i ng for the orbit to change w i n to arntinuour sunlight i n early 1979. Continuous thruster :%Sting IS planned in 1979. Both Ipacecrah and ton thruster systems are near4ully functional whe~i the solar array is illuminated. Thruster system 2 is fullv operational. Thruster system 1 continues to demonrtrate reiight capability, but the high.valtagegrid short remains. (Author)

One life limiting phenomenon of merctlry bombardment thrusters is sputtering erosion of the upstream side of the molyb- denum screen p i d by discharw chamber ions. Data were obtained wt.~ch revealed that rhe xreen grid erosion was very senstlive to the partial pressure of certain uackground gases in the space simulation va:uum fsl l i ty. The results of tests m n d u c t d to e~aluate this effect are presented. An estimate of the xreen grid elosh!sn in space was aadt! which showed that adequate lifetlme for proposed mlsslons exist!..

The current status of knowledge and ability to predict higfn-temperature environmental attack of metals is reviewed withparticular reference to the gas turbine engine, Environmental attack

Is caused by high temperatures, combustion products, and impurities.A schematic fiepresentation of life limiting factors of turbine com-ponents shows that environmental attack can lead to very earlyfailures. Attention is given to high temperature oxidation withprevailing modes of oxidation attack, and to hot corrosion and otherimpurity effects. Erosion attack results from the direct mechanicalremoval of component material by impact of hard substances likeash, sand, or orrt. Solutions to hot corrosion problems can be foundsemiempincally by using improved alloys or ceramics, protectivesurface coatings, additives to the engine environment, and air/fuelcleanup to eliminate detrimental impurities, S.D.

An inexpensive device for pruducntg surface cracks of conUoliedsize and shape is described along with results of its use which showhow the shape of the surface crack changes as it grows in bendingfatigue from a variety of crack starter shapes. The ill owth pattern forany crack is uniquely defined by the crack starter confrgtut+tion andappears to be independent of alloy, Shape changes are substantialand all growth curves tend toward a common growth curve. Circularcracks tend to become elliptical with all increase m stressintensity factor, This increase accole.rates the crack growth rate andproximity to the critical flaw size. Through cracks praducen by theextension of a surface crack fit pending stress held will have lengthtell times the section thickness. The results demonstrate the necessityOf liking into account changmq crack shape it) the calculation ofsvuctural life when bending is a significant component of the stressfield. IAuthoi )

The effect of thermal shock oil spalling of oxides from thesurfaces of several commercial ploys was determined. The averagecooling rate was varied from approximately 240 Clsee to less thenlA C/sec (filling cyclic, oxidation tests in air. The tests consisted ofone hundred cycles of one hour at the maximum temperature (1100of 1200 Q. The alloys were HOS-875, TD-Ni, TO NiCiAI, IN-801,IN 702, and B 1000 plus HL Thermal shock resulted nit deformationof the ninlal which Ili resulted, in most cases, in changing theoxide failure rttudu from commipresitiie to tensifa Tenst!s failures ::arecharacterized by cracking of the oxide and little loss, whilecornpressivo failures were characterized by explosive loss of plateletsof oxide. The thitmall y shocked oxides spalled less than the slowcooled samples with the exception of TO NiCi Al. This material failedIli a brittle manner rather than by plastic deformation. The HOS 875and the TD Ni did not spill during either type of cooling. Thus, theeffect of thermal shock on spalltng is detern)med, in faille part, bythe mechanical properties of :he initial, (Author)

Previous studies and sutveys on avadibility of domestic rescrvcshave shown that chionuum is a most critical element within the U.S.metal industry More Precisely, the bulk o i chromium rs consumed mthe production of stainless steels, specilicdlly Type 304 stainless steel(304SS) which contains 18% Ct, The present paper deals with meansof iw:lucinq chromium m commercial stainless stock by substitutingmore abundant or less expensive elements with the intent ofmaintaining the properties of 304SS, The discussion focuses on someof the oxidation and corrosion properties of new substitute stainlesssteels with only 12% Cr, which represents a potential saving of 331Y0of the chromium consumod in the production of 304SS. The alloyingelements substituted for Cr tit 304SS are selected according to theirpotential for protective oxide formation during high tomperatureoxidation, these are AI, Si, Ti, Y, and misch metal which is 99.7'x,rare-earth mortals containing 50 to 55%s cerium, Other alloyingelements to impart corrosion resistance are Mn, Mo, and V.

Studies have been performed to examine the effect of NaCl vapor on the Na2S04-induced hot cormsion of the alumina former NiAI. In the incubaiion period associated with wch hot corrosion, NaCI(g) has been shown to be effective in rern~ving aluminum from below the protective alumina scale and redepositing it 8s A1103 whiskers on the surface of the NaZS04coated sample. Similar effects seen in simple oxidation are associated with isothermal rupturing of the protective alumina scale. (Author)

Rearltr are glvcn for !on beam texturing of polytmdc (Kapton) and fluorinated ethylene aopylene (Teflon) by means of s 30-ern cftdrn electro*r thunbardrnent argon ion source. Ion beam-texturd Kaptori a d Teflon surfaces ae evduated tor varlous beam energies,

mrrmt dmntles. and expowre times. The optical poprrties and heel resastance are measured after e s h exposure. Rovlded in the paper are opt~cal specha1 data, rssis?~v~ty meastrements, calculared &rorptancr and emlttanca neaurrenients. and surface structure SEM micrographs or varrous exposures to argon ions. I t is found that Kapton b m e s conducting and Teflon nonconductina when ion !warn-textured. Textured Kapton enhrbits l a w changes in the transmittance and solar abrsrpta~xe. but only sllght changes in r '?l Iect~nc~. Surface texturtng of Teflon may allow better adherence ot subsequent spunered metallic fllmr for a high abrorptance value. The results are valuable in spacecraft charging applications. S.D.

The use of crushable energy absorbing layers ~ncreased the limpact resistance of HPSN. Impregnation of RSSN with wlutlons that oxrdizr to A1203 or Zr02 resulted in incread berding strength ~t room temperatura Beta.prime Si-AI-0-N slnterd to full denrrty by means of the rinterrng aids CeO2.

The paper describes the portable earth terminal (PET) and the Vansportable ear* terminal (TET) which enable two-way tdevision and voice communication. Both terminals were dweloped by NASA and utilize the high power of the Hermes satellite. PET is a bus.typc vehicle which has receiving equipment for full duplex color television and whtch can transmlt programs orig~nating in either the on-board PET studio a In nearby buildings PET has a collapsible 2.4-m diameter parabolic antenna interfacing w;th a 500watt 14-GHz wideband TV transmitter and a 12.GEz wideband N receiver svstem. TET uses two parabdic reflector antennas. 3 m a d 1.2 m in diameter. mounted M a flat trailer towed by a truck. TET can receive and relay color TV signals, and its nar-owband transmitter can ser:e a e return audto link permitting a question.ad-an* format. Also described are uplink and downlink performane characteristics, operation procedures, and field demonstrations which enablrd personnel at several hospitals to participate in a distant medtcal conference.

The mesent study identities potential satellite services, examines the technology necessary for efficient implementation or these services, and determines minimum service cost versus user network size. The generic satellite services evaluated comprise TV and radio distribution (for retransmission), video teleconferencing (interactive). audio/facsimile teleconferencing (interactive), multiplexed datalvoice Ipoint.to-point), and satdlite-lupported land mobile. Satellite costs are based on extrapolations from ongoing commercial satellite progams. Production methods. new techndogy, and effezt of product~on quantities on present and future production costs are examined to provide information on earth station equipment cost versus the variable blly'. Six different launch vehicles fmm a Delta 2914 to a dedicated Shuttle and three frequency bands and both broadcest (no eclipse capability) and fixed servce satellites are wmidered to assess the effect ot satellite size on con and performawe. It is asscrmed that the user pays only for his prorata share of the spacc segment cons. SO.

The problem of closure in turbulence in the case of twwpoint correlations resides i n the existence o f two unknowns E and W. the energy soatrum function and tho transfer function. respectively, in the spectrum equation. I n the cesa of weak turbulence. W is neglqible. Iv case of higher correlations. closure can be effective by neglecting the inertia term in the h i m order term used. Specifying a csrtain number of speara at an initial time is also a way o f getting a w n d the closure problem. A simple camof turbclent hear flow is then consdwed, where two-point conelation equations are used and the velocoty is bmken into mean and fluctuating components. This yidds a dinerential equation for the energy spectrum. the three terms of w;irh are the energy spectrum, product~on term and disipatiorr term. They are plotted for a particuhr time. Similar analyoes and c4mfmisons with experiment are mad? for pipe and boundary layer flows. P.T.H.

An experomental and analytical investigation was conducted to determine the free surface shapesof circular jets impinging normal to sharpsdged disks in zero gravity. Experiments conducted in a zero yavity drop tower yielded three distinct flow patterns which were clars~fied in terms of the relative effects of surface tension and inertial forces. An order of magnitude analrsis was conducted indicating regions where VISCOUS forces were not significant when computing free surface shapes. The free surface analysis was simpltfled by transforming the governing potential flow equations and boundary conditmns into the ir.erse plane. The resulting nonlinear equations were solved numerically and comparisns were made with the experimental data for the inertia dominated regime.

The justification for describing a spray by treating drop velocity a a random variable on an equal statortical hasir r i t h drop size was studied experimentally. A doubleexpowre technique using fluorescent drop photography was used to make i r e and velocity measurements at selected locations in a steady ethanol spray formed by a swirl atomizer. The size-velreity data were categorized to construct bivariate spray density functions to descr;w the spray immediately after formatim and during downmeam propagation. It was found that a statistical treatment of drop velocity was supported by the data. Spray density function shapes and modal characteristics depended strongly on position mJ the amount of dropletgas interaction that had occurred. Bimodal density functions were formal by env~ronmental interaction during downstream prop* tion. Large differences were also found between ~patral mass density and mars flux size distributions at the same lrcatioh (Author)

Iagw~se bend~ng, a r l ax~al extension of an untwisted. tonionally rigid, nonuniform, rotatlng beam havlng an arbitrary angle of precone w~ th the plane perpendicular to the axls of rotdtuon are derived us~ng Hamilton's pinc~ple. The derlvrt~on of the equations 1s based on the geometrtc nonlinear t h e y of dast~c~ty and the resulting equattons are mmistent with the &sumpiloci that the stratns ate negligible compared to unity. No ~str~ctions are imposed on the relniw dtrdacements or angular mraftons of the cross sections of the beam other than those implied by the arumptton of tmall strains. Illustrat~w numertcal rerults. obtained I)y us~ng an integrating matrlx as the bas~s for the method of solution, are presented both for the purpose of validat~ng the present method of solution and ~ndrattng the range of appltcabil~ty of the equations of motion and the method of solution.

The paper is cancerreed with the development of electr~c vehicles and electrrc vehicle batteries. The present and pedtcted performance levels of mms battery systems such as lesd.sc~d, nickel-rron. nickel.zinc, and zincchlorine are considered, as are the charac. teristics that an electric vehicle must possess in order to appeal to customers. The implications of b n e w improvements for manufac- turers of elatric vehsles arc dircursd. Lack of knowledge of passenger range requirements for electrtc vehtcles is noted. M.L.

W~th the development of a large magnetized p l m a mume it has h o m e possible to invest~gate space plasma physia problems in the laboratory. First. the nonlinear effects asociated with the exc~t*:lon of a large ampl~tude whistler wave have been explored. It is found that the radiation prerrule of the wave and tkrmal effects give rise to a field-aligned density depresrion in which the wave becomes completely trapped. Hyperfine filaments with diameters mall compared with the parallel wavelength are observed. Second, the stabil~tv of oMiaw Hhlstler waves in the presence of an rlectron .,

beam has been st"d~ed. A broadband whistler instab~lity is observed and identified as a Cherenkov ~nteraction between beam electrons m d whlstlerr propaqattny near the resoname cone. The% observa. ticns confilm the prescnt model tor the generation of VLF hiss in the aurora. (Author)

In addition, nattc aaodynunic performanse data WQ obtained to evaluate the pe~ l t ies produced by these suppression d e v h ~ . Broadband low frequency noise reductions were r h i w d by reducing the separatton distance beween the nozzle and flaps.

A comparison is made between approximate equations for far.field soustic radiation patterns and exact equatiom for single and mult~niadal excitations In order to determine the validity range tor the appoxirnate approach. It is found that tor singlemode caws: (1) the goss behavior of the primary lobes is adequately described by the approximate equations, (2) m e error is found for lower and m o radial order modes, and (3) some sgewnent n yielded between exact and approximate sdelobes, although the approximate equation was not intended to simulate sidelobes. Multimodal approximme equations are compared to exact equations for various distributions of modal power; for all cases excellent agreement is found. For multimodal patterns it is noted that many modes influence the final level and shape of the d~rectrv~ty curve, although the major contr~butions are from the higher radial order modes. S.C.S.

Jet mixing noise data at different muwremcnt distances are compared with values cakubted from the Lockheed prediction method. Although the method does not include any acoustic new-field effects. the measured and predrted revrlts agree well where the memured data deviates from the in- square law. I t is therefore suggested that departures from the inverse square law ere primarily the result of (1) the nonnegligibb dirtan- between the rozrlr exit pbne and t h true axial cwm logtion and (2) the jet mixing noire direetionality. ec modebd in the prediction method. Allowing for thew effects, jet noise data at 8 a d 96 diameters ova a wide r a w of frequencies, angles and jet coml~tions are shown to collapse with reasonable accuracy. (Author1

In particular, the stbbiltcy. structures. structural tra~formation, and binding energy verwr temperature are determined using a Monte Carlo method. The square w r m i d isomer f a N = 5 is found to be unstable at any finite temwature. The other metastable isomers are all found to make spontaneous transitions to the ground state if the temperature is welter than about one half that of melting% Comparisons with prtviws work are also made.

In many caws it has been found that advances made in one tschnical field can contribute to other fiddr An investigation is in this connection conducted concerning subictr fmm contemporary NASA programs and projects which might haw relevance and potentla1 usefulness to tho a~tomottva industry. Exart@- regarding aecospace dewlopments whch have been utilized by the automot;ve indus!ry are relaed to electronic design, computer systems. quality control experience. a NASA combustion scanner and tdevisioh display. exhaust gas adyzers. and a device for ruppming noise popag~ted through ducts. Projects undertlen by NASA's center for propulsion and power research Me examined with respect to their value for the automotive industry. As a result of some of t h projects. a gas turbine engtne and a Stirling engine might each become a posr~ble alternative to the conventional spark ignition mine. G.R.

Data developed by ERDA used to evaluate the performance pnrametels of morlern elearic vehides :s pesentbd with referem to range, acule~ation, mastdown, and haking. Eight of the tened uhlcles had some type of regerrelative braking system. which ptovided range lncteases from 1 to 31 percent. In comparison with conventional vr!hicles, performance was found to oe lower, and rel~abil~ty poorer. Energy consumption was the same, but electric power is less dsmag~ng to the ecvirnnmen! than hydrocarbon fuels, and does not use up an itlcreasinyly scarce resource. D.M.W.
