Space Processing Applications Rocket

(SPAR) Project SPAR IX Final Report.

Compiled by R. Poorman. Marshall Space

Flight Center. N84-17239

The Space Processing Applications Rocket

Project (SPAR) IX Final Report contains tine

compilation of the post-flight reports of each of

the Principal Investigators (PIs) of the three

selected science payloads, in addition to the

engineering report as documented by the Marshall

Space Flight Center (MSFC). This combined

effort also describes pertinent portions of groundbased research leading to the ultimate selection of

the flight sample composition, including design,

fabrication and testing, all of which arr expected

to contribute to an improved comprehension of

materials processing in space.

The SPAR project is coordinated and managed by MSFC as part of the Materials Processing

in Space (MPS) program of the Office of Space

Science and Applications (OSSA) of NASA Headquarters.

This technical memorandum is directed

entirely to the payload manifest flown in tine

ninth of a series of SPAR flights conducted at the

White Sands Missile Range (WSMR) and includes

the experiments entitled "Directional Solidification of Magnetic Composites" (Experiment No.

76-22/2, "Directional Solidification of Immiscible

Aluminum-Indium Alloys" (Experiment Nos.

76-51/1 anc! 76-51/2), and "Comparative Alloy

Solidification" (Experiment No. 76-36/1).

Some Properties of a Five-Parameter Bivarlate Probability Distribution, J. D. Tubbs,

D. W. Brewer, and Orvel E. Smith. Marshall

Space Flight Center. N84-15866

The development of a bivariate gamma

probability distribution and the development of

a new discrete wind gust model are both considered original and significant research accomplishments. In 1981, Smith and Adelfang published

in the Journal of Spacecraft a new wind gust

model based on a four-parameter bivariate gamma

distribution. This gust model related gust magnitude and gust length under the assumption of

equal shape parameters of tine four-parameter

bivariate gamma distribution. This assumption
NASA TECHNICAL MEMORANDUM

proved to be inadequate to properly describe the

wind gust data sample. Since then a five-parameter bivariate gamma distribution having two shapk

parameters, two location parameters and a correlation parameter has been developed. This more

general bivarlate gamma distribution reduces to

the known four-parameter distribution. The fiveparameter distribution gives a better fit to the

gust data, The statistical properties of this general

bivariate gamma distribution and a hypothesis

test have been investigated, Although these

developments have come too late in the Shuttle

program to be used directly as design criteria for

ascent wind gust loads, the new wind gust model

has helped to explain the wind profile conditions

which cause large dynamic loads. Other potential

applications of the newly developed five-parameter bivariate gamma distribution are in the areas

of reliability theory, signal noise, and vibration

mechanics.

Containerless Electromagnetic Levitation

Melting of Cu-Fe and Ag-Ni Alloys, G. J.

Abbaschian and E. C. Ethridge. Space

Science Laboratory. N84-12288

This report summarizes one aspect of the

work carried out in the Space Science Laboratory

of Marshall Space Flight Center under a Technical

Exchange Agreement with Eaton Corp. The

general aim of this aspect of the program was to

investigate the feasibility of producing silver or

copper alloys containing finely dispersed nickel

or iron particles, respectively, b" utilizing containerless electromagnetic levitation casting techniques. A levitation coil was designed to successfully levitate and melt a variety of alloys including Nb-Ge, Cu-Fe, Fe-C, and Ag-Ni. The highest

melt temperature achieved by the coil was about

2400°C during melting of Nb-Ge alloys. Samples

of 70 Cu-30 Fe and 80 Ag-20 Ni (atomic `I),

prepared by mechanical pressing of the constituent powders, were levitated and heated either

to the solid plus liquid range of the alloys or to

the fully liquid region. Tire samples were then

solidified by passing helium gas into the bell jar

or they were dropped into a quenching oil, The

structure of the samples which were heated to

the solid plus liquid range consists of uniform

distribution of Fe or Ni particles in their respective matrices. They also contained a considerable

amount of entrapped gas bubbles. Upon heating

for longer periods or to higher temperatures, the

bubbles coalesced and burst, causing the samples

to become fragmented and usually fall out of the

coil. The structure of the Cu-Fe samples that were

fully liquid and solidified while levitated

consisted of the fine iron dendrites distributed

uniformly in the copper matrix. For Ag-Ni

samples, due to the existence of immiscibility gap

Potential Means of Support for Materials

Processing in Space—A History of Government Support for New Teclmology, Eugene

C. McKamnan. Materials and Processes

Laboratory. N84.13205

A debate has been going on in government

on the subject of "Should government funds be

spent on early research and high-risk development

of new technology?" Opponents claim that if a

product is worth the effort, then private enterprise will invest in it. Proponents claim that we

are all beneficiaries of new technology. Today,

the answer impinges on doing materials processing

and other commercial endeavors in space. Here,

we discuss past experience in nurturing new ideas,

and find two themes. In the first, the military

initiates development of a given technology for

national defense, and the marketplace makes use

of the technology. In the second, the government

supports large systems developments when the

task is too large or risky for entrepreneurs, yet

is clearly in the best interest of the nation. NASA

has completed advanced research to identify areas

of interest. Examples of commercial opportunities are the McDonnell-Douglas Corporation

purification process for pharmaceutical products

and the Microgravity Research Associates process

for growing gallium arsenide crystals in space.

Additional technology developments are in the

pipeline.

This model includes the effects of an upstream

elbow, arbitrary geometry, and multiple plies.

A refined computer code for predicting flowinduced stress is described which allows life

prediction if a material S-N diagram is available.

Solidification Rate Influence on Orientation

and Mechanical Properties of MAR-M246+hf. David Hamilton, Materials and

Processes Laboratory. N84-14290

The influence of solidification rates on the

orientation and mechanical properties of MAR-M246+11f was studied. The preferred orientation

was found to be (001) for single crystals, with all

samples with 45° of (001).

Tensile tests were performed at room temperature. The anisotropy of directionally solidified MAR-M-246+Hf was demonstrated by gage

section deformation.

Dendrite arm spacing and crystal growth

were found to depend on solidification rates and

source material conditions. The greatest strength

occurred at lower solidification rates. Some single

crystals were grown by control of growth rates

without seeding.

L. M. 'Thompson, Dr. J. M. Stuckey, Don.

Wilkes and Dr. Randy Humphries. Materials

and Processes Laboratory. N84-15269

This task was directed toward demonstrating

the feasibility of using a scrim-reinforced, single

metallized, 4-mil Tedlar film as a replacement

for the Teflon coated Beta-cloth/single metallized

3-mil Kapton film presently used as the protective cover/light block for multilayer insulation

(MLI) on the Orbiter, Spacelab, and other space

applications. The proposed Tedlar concept will be

lighter and potentially lower in cost. Thermal

analysis with the proposed concept was much

simpler than with the present system. Tests have

already demonstrated that white Tedlar has low

aipha (adsorption) degradation in space from

U.V. This study indicated that proposed concept

was 4400 percent cheaper with nominal weight

savings of 50 percent.

Evidence Linking Coronal Mass Ejections

with Interplanetary "Magnetic Clouds."

Robert M. Wilson and Ernot Hildner.

Space Science Laboratory. N84-18141

Using proxy data for the occurrence of those

mass ejections from the solar corona which are

directed earthward, we investigate the association

between the post-1970 interplanetary magnetic

Clouds of Mein and Burlaga and coronal mass

ejections. The evidence linking magnetic clouds

following shocks with coronal mass ejections is

striking; six of nine clouds observed at Earth

were preceded an appropriate time earlier by

meter-wave type 1I radio bursts indicative of

coronal shock waves and coronal mass ejections

occurring near central meridian. During the

selected periods when no clouds were detected

near Earth, the only type II bursts reported were

associated with solar activity near the limbs.

Where the proxy solar data to be sought are not

so clearly suggested, that is, for clouds preceding

interaction regions and clutids within cold magnetic enhancements, the evidence linking the

clouds and coronal mass ejections is not as clear;

proxy data usually suggest many candidate massejection events for each cloud. Overall, the data

are consistent with and support the hypothesis

suggested by Klein and Burlaga that magnetic

clouds observed with spacecraft at 1 AU are

manifestations of solar coronal mass ejection

transients. A condensed version of this study is

to be published in Solar Physics.

Low Loss Injector for Space Shuttle Main

Engine, Center Director's Discretionary

Fund, Final Report. George L. von Pragenau. Systems Dynamics Laboratoryy.

N84-19469

An efficient propellant injection method is

discussed to raise the Space Shuttle Main Frigine

(SSME) thrust and payload. Relatively large

diameter injector elements with low pressure loss

are recommended for the main combustion chamber and the pri;-burners, Smaller losses admit

more propellant flow which then raises thrust.

Payload is not only gallned by specific impulse but

also by thrust. The chamber pressure is stabilized

by selecting the proper cavity size for the injector

elements while reducing the injection pressure

loss which normally is kept high for stability.

The rather large injector element recesses provide

acoustic damping which makes baffles and

a tenfold reduction of flow induced stresses

which are rather high ; 1 the present design.

The New MSFC Solar Vector Magnetograph

Center Director's Discretionary Fund, Final

Report. M. J. Hagyard, E, A. West, and

N84-19786

The unique MSFC solar vector magneograph allows measurements of all three components of the Sun's photospheric magnetic field over

a wide field-of-view (^ 6x6 are min) with spatial

resolution determined by a 2.7x2.7 are sWeond

pixel size. Supported by two Center Director's

Discretionary Fund Projects, this system has

recently undergone extensive modifications to

improve its sensitivity and temporal response.

The modifications included: replacing an SEC

vidicon detector with a solid-state CCD camera;

replacing the original digital logic circuitry with

an electronic controller and a computer to

provide complete, programmable control over the

entire operation of the magnetograph; and installing a new polarimeter which consists of a single

electro-optical modulator coupled with Interchangeable waveplates mounted on a rotating

assunbly. In this report, we describe the new

system, and present results of calibrations and

tests that have been performed. Initial observations of solar magnetic fields with the new magnetograph are presented; they indicate that the

system is an order of magnitude more sensitive

than the original one and has a much higher

temporal response (by a factor of X30). These

new capabilities enhance our continued research

in solar vector magnetic fields and our support

of NASA's solar missions,

basic morphology and fatigue properties. Of particular Interest was the degradation of fatigue

properties with deviation from the [001 1 growth

shape and Interdendritic segregation on growth

rat,;. Heat treatment studies focused on the

r,°^ 1ma prime structure, determining that it

reaches maximum growth after twenty-four

hours but Its size and stability depends on the

temperature of the treatment Fatigue test specimens were oriented crystallographically in the

failed and unfailed regions and found to have

rotated their orientation during the testing if

they were located a significant distance from

Application of VISSR Atmospheric Sounder

(VAS) Data. Gary J. Jedlovec. Systems

Dynamics Laboratory, N84-23073

Recent studies using sounding data derived

from VAS radiance measurements have projected

a hope for increased time and space resolution

of the mesoscale environment. Working with this

new data, however, presents some problems

normally not encountered when using conventional measurements because of the irregular

spacing of the data, biases in the data, as well as

errors due to cloud contaminated measurements.

This report addresses these problems and presents

an objective analysis technique which utilizes

LFM guess fields to produce a consistent fourdimensional data set which adequately describes

the mesoscale environment over a large area.

Parameters derived from this data set can be

useful in a diagnostic mode by both the operational and research communities,

An investigation of thermospheric; winds,

relative to the space station orbital altitudes, has

been made In order to provide information that

may be useful in an cnti;ronmental disturbance

assessment. Current plans are for this low Earth

orbiting facility to orbit at an inclination of 28,5

defined due to the evolutionary configuration of

the Space Station. The upper and lower bounds

of the orbital altitudes will be based oil

 set by the drag and expected orbital

Separation Processes During Binary Monotectic Alloy Production. Donald O. Frazier,

Barbara R. Faeemire, William F. Kaukler,

William K. Witherow, and Ursula Fanning.

Space Science Laboratory, N84-24773

Generally, attempts to solidify immiscible

mixtures to make binary alloys, in-situ, yield

poorly dispersed composites. By and large, the

situation is more pronounced for hypermonotectic compositions than for either monotectic or

hypomonotectic solutions. There Is considerable

interest among metallurgists to understand processes causing liquid-liquid and solid-liquid phase

separations during monotectic alloy solidification.

Knowledge of such dynamics must precede accurate predictability of the behaviors of solidifying
NASA TECHNICAL MEMORANDUM

metallic systems and control of their microstructure.

If a homogeneous melt is cooled into an

immiscible region, the newly formed second

phase will generally have a density different from

the parent phase, and will separate readily by

sedimentation. Observation of microgravity solidification processes indicates that outside of sedimentation, at least two other important effects

can separate the phases: ( 1) critical-point wetting

and spreading, and (2) thermal migration of

second-phase droplets due to interfacial tension

gradients. It is difficult to study these surface

tension effects while in a unit gravity field. Considerable work has been done using neutrally

buoyant systems, but such systems are generally

neutrally buoyant at only one temperature.

Therefore, in order to investigate the processes

occurring over a temperature range, i .e., between

a consolute point and the monotectic temperature, it is necessary to use a low-gravity environment. The MSFC drop tube (and tower), the

ballistic trajectory KC-135 airplane, and the

Space Shuttle are ideal facilities to aid formation

and testing of hypotheses.

Much of the early work in this area focuses

on transparent materials so that process dynamics

may be studied by optical techniques such as

photography for viewing macro-processes;

holography for studying diffusional growth,

spinodal decomposition and coalescence; ellipsometry for surface wetting and spreading effects;

and interferometry and spectroscopy for smallscale spatial resolution of concentration profiles.

Finally, computer models developed from

the transparent model studies will be quite

helpful when applied to existing metallic specimens already prepared in low gravity. Additional

metallic samples solidified in the MSFC drop

tower will test the accuracy of predictions based

on such studies.

An Investigation Into the Probabilistic

Combiaiation of Quasi-Static and Random

Accelerations, Richard W. Shock and Lenox

P. Tuell. Systems Dynamics Laboratory,

N84-28111

The development of design load factors for

aerospace and aircraft components and experiment support structures, which are subject to a

s multaneous vehicle dynamic vibration (quasistatic) and acoustically generated random vibration, require the selection of a combir,7tion

methodology. Typically, the procedure is to

define the quasi-static and the random generated

response separately, and arithmetically add or

root sum square to get combined accelerations.

Since the combination of a probabilistic and a

deterministic function yield a probabilistic function, a viable alternate approach would be to

determine the characteristics of the combined

acceleration probability density Ainction and

select an appropriate percentile level for the

combined acceleration. The following paper

develops this mechanism and provides graphical

data to select combined accelerations for most

Popular percentile levels.

Nighttime Observations of Thunderstorm

Electrical Activity from a High Altitude

Airplane, M. Brook, C. Rhodes, O. H,

Vaughan, Jr., R. E. Orville, and B. Vonnegut.

Marshall Space Flight Center.

Two sets of observations from a NASA U-2

airplane flying at approximately 20 km altitude

over nocturnal thunderstorms are reported.

Photographs show frequent lightning activity in

the upper part of the cloud. In some cases, only

the diffuse illumination produced by the lightning can be seen. In other cases unobscured

segments of lightning channels 1 km or longer are

visible in clear air around and above the cloud.

Multiple images of lightning channels, accidentally displaced on the film during transport of the

film in the camera, indicate multiple discharges

in the same channel. Photographs taken through

a diffraction grating show that the lightning has

a spectrum similar to that which has been

observed in the lower troposphere. Lightning

spectra obtained with a slitless line-scan spectrometer show strong singly ionized nitrogen

emissions at 463.0 and 500.5 nm. Field changes

measured with an electric field-change meter

correlate with pulses measured with a photocell

optical system.

Optical signals corresponding to dart leader,

return stroke, and continuing current events are

readily distinguished in the scattered light emerging from the cloud surface. The •. v ariation of light

intensity with tinnc in lightning events, such as

dart leaders, which radiate light first from a location within the cloud and later from outside

(beneath) the cloud are consistent with the

predicted modification of optical lightning signal;,

by clouds as given by Thomason and Krider [ 1 ] .

As a result, it appears that satellite based optical

sensor measurements cannot provide reliable

information on current rise times in return

strokes. On the other hand, discrimination

between cloud-to-ground and intracloud flashes

and the counting of ground strokes is possible

using the optical pulse pairs which have been

identified with leader, return-stroke events in the
NASA TECHNICAL MEMORANDUM

cloud-to-ground flashes studied. If confirmed by

further studies as a regularly Identifiable occurrence, the pulse pairs together with other criteria,

could form the basis for the reliable Identification of ground strokes from a satellite by the use

of an optical detector alone.

It has been found unexpectcdly that a multitude of weak lightning channels commonly exists

in the clear air above or around cloud tops. This

indicates that lightning is capable of introducing

chemical species, ions, and space charge directly

into the upper troposphere and lower

stratosphere.

Testing and Evaluation of Vespel up to

450°F When Used in Ntits and Bolts as a

Self-Locking Element. Carl M. Wood,

Marshall Space Flight Center.

The object of this investigation was to

evaluate Vespel for potential application on the

Solid Rocket Booster to replace all-metal

deformed self-locking nuts and anchor nuts and

be used as self-locking elements for bolts and

screws. The Vespel self-locking elements were

tested for prevailing torque retention at room

temperature, after heating to 450°F and exposure

for 3 hr, breakaway torque at 450°F and for

vibration at a level consistent vith the maximum

expected on the SRB at lift-off and reentry.

The investigation revealed Vespel has properties that can provide a self-locking capability

for threaded fasteners up to 450°F and it can be

used in nuts and anchor nuts for installation on

the SRB. Vespel elements in bolts did not meet

all our SRB requirements for reuse, however, we

have defined a design for Vespel elements in

nuts/anchor nuts that fully meets all requirements.

It is recommended that No. 10, 1/4 in. and

5/16 in. nuts/anchor nuts be procured for use on

the SRB. This system will eliminate the galling

problems now encountered and achieve a much

higher reuse life than the present deformed nut

design.

On Long-Term Periodicities in t1.- Sunspot

Record. Robert M. Wilson. Space Science

Laboratory.

Sunspot records have been systematically

maintained, with the knowledge that an 11-year

average period exists, since about 1850. Thus,

the sunspot record of highest quality and considered to be the most reliable is that of cycle 8

through the present. On the basis of cycles 8

through 20, we have used various combinations

of sine curves to approximate the observed

RMAX values (where RMAX is the smoothed

sunspot number at cycle maximum). We find that

a three-component sinusoidal function, having

an 11-cycle and a 2-cycle variation on a 90-cycle

periodicity, yields computed RMAX v.Aues which

fit, reasonably well, observed RMAX values for

- -two ^-
NASA TECHNICAL MEMORANDUM

.... ........ ... sunspot cycles. Extrapolation of the

empirical function forward in time allows us to

project values of RMAX for cycles 21 and 22.

For cycle 21, the function projects a value of

157.3, very close to the actually observed value

of 164.5 and to that predicted earlier by Sargent

[64) - 154, For cycle 22, the function projects

a value of about 107. Linear regressions identified

in Wilson [44] have been applied to cycle 22,

yielding the result that it will probably be a longperiod cycle (cycle duration > 132 months).

50 grams of this high polymer in a single run.

The reactive monomer approach was also inves

tigated using the following aminoNilanes: bis-

(dimethylamino)dimetliylsilane, N, N-bis(pyrroUdinyl)dimethylsilane and N, N-bis (gammabutyrolactam)dimethylsilane. Thermal analyses

were performed in both air and nitrogen, The

experimental polymers decomposed at 540° to

562'C, as opposed to 4080 to 426°C for coinmercial silicones. Differential scanning calorimetry showed a glass transition (Tg) at -500 to

-55°C for the silphenylene-siloxane copolymer

while the commercial silicones had Tg's at -960

to -112°C.

Automatic Rendezvo,.is and Docking: A

Parametric Study, Richard Dabney. Systems

Dynamics Laboratory. N84-23677

A technique for achieving autonomous rendezvous and docking of two orbiting space

vehicles is described. Results of a digital computer

simulation of the technique are presented and

used to evaluate its performance under a wide

variety of conditions, including docking with

tumbling spacecraft. The interrelationships

between initial range, tumbling rates, fuel consumption, and time requirements are explored;

factors which limit performance are identified

and beneficial modifications proposed.

A Spatial Model of Wind Shear and Turbulence for Flight Simulation. C. Warren

Campbell. Systems Dynamics Laboratory.

N84-24044

A three-dimensional model which combines

measurements of wind shear in the real atmosphere with three-dimensional Monte Carlo

simulated turbulence was developed, The
NASA TECHNICAL PAPERS

measurement of three-dimensional wind shear Is

a recent development, Measurements were mide

on a rather coarse (^200 m) grid scale so that

high frequency, short length scale turbulence

Information was not included, Some of the

missing frequencies are important to aircraft

response and hence for flight simulation, The

missing turbulence must be added to the wind

shear measurements. The spatial model adds

three-dimensional, Monte Carlo simulated turbulence conforming to the von Karman model. The

turbulence was generated in the frequency

domain and transformed to the space domain

using Fast Fourier Transform techniques. The

resulting turbulence is three-dimensional and

contains lateral and vertical as well as longitudinal

correlations associated with isotropic turbulence.

The resulting Gaussian, isotropic turbulence is

multiplied by a spatially varying gust intensity

and added to the wind shear data set winds. The

resulting simulated wind field is nonisotropic,

non-Gaussian, and nonlinear as are winds in the

real atmosphere. Previous turbulence simulations

were either one-dimensional or accounted for

two- or three-dimensionality in an artificial way.

With the present model, the wind field over the

body of an aircraft can be simulated and all

aerodynamic loads and moments calculated, The

inclusion of three-dimensional variation of winds

and turbulence is believed to be a significant

advance over previous wind simulation models.

Shock Response Spectra Variational Analysis for Pyrotechnic Qualification Testing of

Flight Hardware. James Lee Smith. Systems

Dynamics Laboratory. N84-23676

Shock response spectra data from flight

certification tests were analyzed to determine

envelope variation with respect to mean values

in each axis. An overall variation of ±8.61 dB or

169 percent exists for the data. This large variation may be attributed to one or more of the

following;

(1) Instrumentation Problems may exist.

(2) Variations in the source charge (blasting

caps) such as shape or explosive load may exist.

(3) Two blasting caps were used to excite

the pyrotechnic plate tester. Delay time between

charge firings may have varied,

The cause or causes of the variations need to be

identified and researched to prevent future pyro.,

shock problems,

Finite-Difference Fluid Dynamics Computer

Mathematical Models for the Design and

Interpretation of Experiments for Space

Flight. Glyn O. Roberts, WIlliam W. Fowlis,

and Timothy L. Miller. Space Science Laboratory. N84-23852

A major objective of NASA's Spacelab is to

exploit the microgravity environment of an orbiting vehicle for science and technology, There are

many fundamental fluid dynamics experiments

and materials processing studies involving fluid

motions which can only achieve their fu'll potential in a low-gravity environment. The many

constraints and high costs of space experimentation mean that quantitative and detailed scientific

and engineering design studies should be .performed before proceeding to the construction of

flight apparatus. However, for experiments involving fluid dynamics, such studies are not easily performed. Analytical methods are severely limited

in their range of applicability by fundamental

mathematical difficulties. Experimental measurement cannot, in principle, be performed until

the apparatus is built and flown, but even laboratory analogs can present substantial difficulties

to a detailed measurement program. The solution

to the above difficulties can often be found in

numerical modeling. Recent advances in

numerical modeling methods mean that accurate

numerical models for many fluid flow problems

can now be developed in a systematic manner,

and the continued improvement in computer

hardware means that these models can be run in

a relatively short time. In particular, models of

non-turbulent, incompressible fluid flows in

simple geometries can be developed to provide

accurate and detailed data.

Numerical methods are used to design a

spherical baroclinic flow model experiment of

the large-scale atmosphere flow for Spacelab.

NASA TECHNICAL PAPERS

The dielectric simulation of radial gravity Is only

dominant in a low-gravity environment. Computer codes are developed to study the processes

at work In crystal growing systems which are

also candidates for space flight. Crystalline materials rarely achieve their potential properties

because of Imperfections and component concentration variations. Thermosolutal convection in

the liquid melt can be the cause of these Imperfections, Such convection Is suppressed in a lowgravity environment.

Two- and three-dimensional finite-difference

codes are being used for this work. Nonuniform

meshes and implicit iterative methods are used.

The iterative method for steady solutions is based

on time-stepping but has the options of different

time steps for velocity and temperature and of a

time step varying smoothly with position according to specified powers of the mesh spacings.

This allows for more rapid convergence, The code

being developed for the crystal growth studies

allows for growth of the crystal at the solid-liquid

interface, The moving interface is followed using

finite differences; shape variations are permitted.

For convenience in applying finite differences in

the solid and liquid, a time-dependent coordinate

transformation is used to make this interface a

coordinate surface.

A Comparative Look at Sunspot Cycles.

Robert M. Wilson. Space Science Laboratory. N84-24520

On the basis of cycles 8 through 20, spanning about 143 years, observations of sunspot

number, smoothed sunspot number, and their

temporal properties have been used to compute

means, standard deviations, ranges, and frequency

of occurrence histograms for a number of sunspot

cycle parameters (e.g., RMIN, RMAX, ASC, DES,

etc.). The resultant "schematic" sunspot cycle

has been contrasted with the "mean" sunspot

cycle, obtained by averaging smoothed sunspot

number as a function of time, tying all cycles

(8 through 20) to their minimum occurrence

date. A relatively good approximation of the time

variation of smoothed sunspot number for a

given cycle is possible if sunspot cycles are

regarded in terms of being either HIGH- or

LOW- AX cycles or LONG- or SNORTPERION cycles, especially the latter. Further,

sunspot cycles denoted HIGHAMAX usually are

SHORT-PERIOD cycles and those denoted LOWRmAX usually are LONG-PERIOD cycles.

Linear regression analyses have been performed

comparing late cycle parameters with early cycle

parameters and solar cycle number (SCN), and

the early occurrri

g

ng cycle parameters RMIN,

A R13 and r RZ(t), especially the latter

tw0

two, can be used to estimate later occurring cycle

parameters with relatively good success, based on

cycle 21 as an example. The sunspot cycle record

clearly shows that the trend for both RMIN and

RMAX was toward decreasing value between

cycles 8 through 14 and toward increasing value

between cycles 14 through 20, Linear regression

equations have also been obtained for several

measures of solar activity — RA, RZ (now RI),

R 13, F2800, and f' 13 on the basis of provisional

and final values.

Geometric Interpretations of the Discrete

Fourier Transform (DFT). C. Warren Campbell. Systems Dynamics Laboratory.

N84-24114

A recent tendency in technical literature

has been to ignore the relationship of the DFT

to the real world. Rather the DFT has become an

end unto itself. This attitude is somewhat surprising since the DFT's reason for existence is

its relationship to the real, i.e., v, °tinuous, world.

One-, two-, and three-dimension.:, DFTs and

geometric interpretations of their periodicities

are presented. These operators are examined in

light of their relationship with the two-sided,

continuous Fourier transform. Discrete or continuous transforms of real functions have certain

symmetry properties. These symmetries are

examined in detail for the one-, two-, and threedimensional cases. Extension to higher

dimensions is straight-forward,

A Stochastic Model for Photon Noise

Induced by Charged Particles In Multiplier

Phototubes of the Space Telescope Fine

Guidance Sensors. Leonard W. Nowell and

Hans F. Kennel. Systems Dynamics Laboratory, N84-26398

The Space Telescope (ST) will be subjected

to charged particle strikes in its space environment. ST's onboard Fine Guidance Sensors utilize

multiplier phototubes (PMT) for attitude determination. These tubes, when subjected to charged

particle strikes, generate "spurious" photons in

the form of Cerenkov radiation and fluorescence

which give rise to unwanted disturbances in the

pointing of the telescope.

This paper presents a stochastic model for

the number of these spurious photons which

strike the photocathode of the multiplier phototube which in turn produce the unwanted photon

noise. The model is applicable to both galactic

cosmic rays and charged particles trapped in the

Earth's radiation belts.

The model which has been programmed

allows for easy adaptation to a wide range of

particles and different parameters for the phototube of the multiplier.

The probability density functions for

photon noise caused by protons, alpha particles,

and carbon nuclei were generated using thousands

of simulated strikes. These distributions will be

used as part of an overall ST dynamics simulation.

The sensitivity of the density function to

changes in the window parameters has also been

investigated.
