in helping NASA maintain this important role.

The NASA STI Program Office is operated by

Langley Research Center, the Lead Center for

NASA’s scientific and technical information. The

NASA STI Program Office provides access to the

NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA’s institutional

mechanism for disseminating the results of its

research and development activities. These results

are published by NASA in the NASA STI Report

Series, which includes the following report types:

• TECHNICAL PUBLICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data

or theoretical analysis. Includes compilations

of significant scientific and technical data and

information deemed to be of continuing

reference value. NASA’s counterpart of peerreviewed formal professional papers but

has less stringent limitations on manuscript

length and extent of graphic presentations.

• TECHNICAL MEMORANDUM. Scientific

and technical findings that are preliminary or

of specialized interest, e.g., quick release

reports, working papers, and bibliographies

that contain minimal annotation. Does not

contain extensive analysis.

• CONTRACTOR REPORT. Scientific and

technical findings by NASA-sponsored

contractors and grantees.

• CONFERENCE PUBLICATION. Collected

papers from scientific and technical

conferences, symposia, seminars, or other

meetings sponsored or cosponsored by

NASA.

• SPECIAL PUBLICATION. Scientific,

technical, or historical information from

NASA programs, projects, and missions,

often concerned with subjects having

substantial public interest.

• TECHNICAL TRANSLATION. Englishlanguage translations of foreign scientific

and technical material pertinent to NASA’s

mission.

Specialized services that complement the STI

Program Office’s diverse offerings include

creating custom thesauri, building customized

databases, organizing and publishing research

results . . . even providing videos.

ABSTRACT

This research effort was a feasibility study of the concept of an all-optical micro motor with a

rotor driven by a traveling wave. The wave was a result of a photo induced surface deformation

of a photosensitive material produced by a traveling holographic grating. Two phases modulated

coherent optical beams were used to generate the grating in two types of photosensitive materials. The materials that were studied were photorefractive crystals and thin polymer films. Theoretical studies were performed on lithium niobate giving predictions of deformations of the order

of nanometers. The experimental deformation size was also on the order of nanometers. The

deformations were deep enough to provide conditions for the implementation of the all-optical

motor using lithium niobate. We also were able to align micron-size dielectric particles along the

holographic gratings by means of the periodic electric forces generated by the grating. These

forces can also move the particles along the surface if the grating is moving. We then turned our

attention on thin films and obtained a deformation visible on the order of 100 microns. An experimental breadboard demonstration of a prototype was done in the summer of 2001 at GRC. The

demonstration included the movement of clocks mechanical workings by an optically driven

motor based on a polymer film. The application of this technology can be adapted to government as well as industrial uses. One such project is to make a chemical sensor for the detection

of hazardous chemicals. The thin polymer film is highly suited for this purpose since a marker

dye could be easily placed on the film in order to detect chemical compounds. This system could

be a self-regulating chemical monitoring system used on launches of the space shuttle or

locations where hazardous chemicals are present. The project provided support for two black

minority graduate students targeting MS and PhD degrees in Applied Optics.

ABSTRACT

The main objective of this NASA FAR project is to conduct ultrasonic assessment of

impact-induced damage and microcracking in fiber-metal laminated (FML) composites at various temperatures. It is believed that the proposed study of impact damage assessment on FML

composites will benefit several NASA’s missions and current interests, such as ballistic impact

testing of composite fan containment and high strain rate deformation modeling of polymer

matrix composites. Impact-induced damage mechanisms in GLARE and ARALL fiber-metal

laminates subject to instrumented drop-weight impacts at various temperatures were studied.

GLARE and ARALL are hybrid composites made of alternating layers of aluminum and glass-

(for GLARE) and aramid- (for ARALL) fiber reinforced epoxy. Damage in pure aluminum panels

impacted by foreign objects was mainly characterized by large plastic deformation surrounding a

deep penetration dent. On the other hand, plastic deformation in fiber-metal laminates was often

not as severe although the penetration dent was still produced. The more stiff fiber-reinforced

epoxy layers provided better bending rigidity; thus, enhancing impact damage tolerance. Severe

cracking, however, occurred due to the use of these more brittle fiber-reinforced epoxy layers.

Fracture patterns, e.g., crack length and delamination size, were greatly affected by the lay-up

configuration rather than by the number of layers, which implies that thickness effect was not

significant for the panels tested in this study. Immersion ultrasound techniques were then used

to assess damages generated by instrumented drop-weight impacts onto these fiber-metal

laminate panels as well as 2024-T3 aluminum/cast acrylic sandwich plates adhered by epoxy.

Depending on several parameters, such as impact velocity, mass, temperature, laminate configuration, sandwich construction, etc., various types of impact damage were observed, including plastic deformation, radiating cracks emanating from the impact site, ring cracks surrounding

the impact site, partial and full delamination, and combinations of these damages.

ABSTRACT

Our research focuses on development of novel p-conjugated polymers with desired emission. In the current study, the structure of a highly green-emitting poly[(m-phenylenevinylene)-

alt-(p-phenylenevinylene)] has been modified by increasing the content of p-phenylene to

achieve red- and infrared-emission. The polymer is synthesized via Wittig-Horner condensation,

which is known to lead to trans-olefin linkage. The polymer is soluble in common organic solvents such as toluene, chloroform and THF. The spectroscopic properties of the polymer in both

solution and film states will be discussed in comparison with its model compound.

ABSTRACT

Carbon nanotubes have the potential to significantly enhance the mechanical, thermal, and

electrical properties of polymers. However, dispersion of carbon nanotubes in a polymer matrix

is hindered by the electrostatic forces that cause them to agglomerate. Chemical modification of

the nanotubes is necessary to minimize these electrostatic forces and promote adhesion between the nanotubes and the polymer matrix. In a collaborative research program between

Clark Atlanta University, Rice University, and NASA Glenn Research Center several approaches

are being explored to chemically modify carbon nanotubes. The results of this research will be

presented.

ABSTRACT

Ultra-lightweight materials have played a significant role in nearly every area of human

activity ranging from magnetic tapes and artificial organs to atmospheric balloons and space

inflatables. The application range of ultra-lightweight materials in past decades has expanded

dramatically due to their unsurpassed efficiency in terms of low weight and high compliance

properties. A new generation of ultra-lightweight materials involving advanced polymeric materials, such as TEEKTM polyimide foams, is beginning to emerge to produce novel performance

from ultra-lightweight systems for space applications. As a result, they require that special

conditions be fulfilled to ensure adequate structural performance, shape retention, and thermal

stability. It is therefore important and essential to develop methodologies for predicting the

complex properties of ultra-lightweight foams. To support NASA programs such as the Reusable

Launch Vehicle (RLV), Clark Atlanta University, along with SORDAL, Inc., has initiated projects

for commercial process development of polyimide foams for the proposed cryogenic tank integrated structure (see figure 1). Fabrication and characterization of high temperature, advanced

aerospace-grade polyimide foams and filled foam sandwich composites for specified lifetimes in

NASA space applications, as well as quantifying the lifetime of components, are immensely

attractive goals. In order to improve the development, durability, safety, and life cycle performance of ultra-lightweight polymeric foams, test methods for the properties are constant concerns in terms of timeliness, reliability, and cost. A major challenge is to identify the mechanisms

of failures (i.e., core failure, interfacial debonding, and crack development) that are reflected in

the measured properties. The long-term goal of the this research is to develop the tools and

capabilities necessary to successfully engineer ultra-lightweight polymeric foams. The desire is

to reduce density at the material and structural levels, while at the same time maintaining or

increasing mechanical and other properties.

Effects of Impact Damage in Midplane Asymmetric Sandwich Composites

Atlanta, Georgia 30314

ABSTRACT

Several structural sandwich composites arc in service on military and commercial aerospace

vehicles, however, these components have been limited to secondary structures partly because

the impact damage and damage tolerance of these composites have not been extensively

characterized. To improve durability, safety, and life cycle performance of PMCs while reducing

maintenance costs, combined analysis, and test methods that provide a means of predicting

critical engineering properties after impact damage of the structure, must be developed. A key

enabling technology here is the establishment of the correlation between the impact test results

conducted in the laboratory and the mechanics-based phenomenological solutions. This research was undertaken to investigate the compression and flexural properties following low

velocity impact of a nomex/phenolic honeycomb core, fiberglass/epoxy facesheet, midplane

asymmetric sandwich composite. One facesheet (thin side) was composed of two plies of the

fiberglass/epoxy (0/90), while the other facesheet (thick side) was composed of four plies

(0/90/0/90) of fiberglass/epoxy. Due to the differences in facesheet thickness, impact damage

was separately induced on the thick side as well as the thin side. The compression and flexural

strength properties for each damage arrangement were compared using different levels of

impact energy ranging from 0 to 452 Joules (see figure 1). In all cases, higher impact energy

resulted in decreased compression and flexural strength. Impact on the thin side showed slightly

more retention of compression strength at low impact levels, whereas higher residual compressive strength was observed from impact on the thick side at higher impact levels. Different

facesheet thicknesses or midplane asymmetry, played an important role in the flexural strength,

however, low velocity impact on the both the thick and thin fiberglass/epoxy facesheet side

showed an almost linear loss of flexural strength to saturation.

ABSTRACT

This research used mixed structured singular value theory to develop new estimator (or

observer) based approaches to fault detection for dynamic systems. The initial developments

were based on minimizing the H-infinity, l-1 and H2 system norms. The resultant fault detection

algorithms were each shown to be successful, but the fault detection algorithm based on the l-1

norm was best able to detect abrupt faults. This latter technique was further improved by using

fuzzy logic for the fault evaluation. Based on an anomaly observed in this research and apparently ignored in the literature, current research focuses on the determination of a fault using a

norm of the change in the residual (the difference between the output of the system and observer) and not simply a norm of the residual itself. This research may lead to a fundamental

contribution to research in fault detection and isolation.

ABSTRACT

This report presented contains the main results of joint research between the Hampton University Fluid

Mechanics and Acoustics Laboratory (FM&AL), NASA GRC, and the Institute of Mechanics at Moscow State

University (IM/MSU) in Russia. This research is also supported by a CRDF grant. Four subprojects were

conducted using analytical methods, numerical simulation and experimental tests: (A) Shock wave mitigation by

spike-shaped blunt bodies with application for the purpose of drag, lift and longitudinal momentum optimization.

The main result in this subproject is: application of a single needle against a supersonic flow provides higher

benefits for blunt body drag reduction and heat transfer to the body than the application of multiple needles.

(B) Solid particles, liquid and air jet injection through the front of a blunt body against a supersonic flow. In this

case, the research conducted and analysis of multiple previous investigations in this area have shown essential

benefits and preferable application of solid particle injection. (C) Comparison of different methods of fuel

injection into supersonic duct flows. Preliminary numerical simulations and theoretical analysis show promising

results for Telescope-shaped inlet applications in SCRAMJET; and (D) Development of an acoustic source

location method for different applications including propulsion systems. The main outcomes during this reporting period are: (1) Presentation of papers: An AIAA Paper 01–1893 at the AIAA/NAL–NASDA–ISAS 10th

International Space Planes and Hypersonic Systems and Technologies Conference, 24–27 April 2001, Kyoto,

Japan. Also, an AIAA Paper 01–3204 at the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference,

08–11 July 2001, Salt Lake City, Utah; and 2 reports at the HBCUs/OMUs Research Conference, OAI/NASA

GRC, 17–18 April 2001. (2) Four abstracts were submitted and accepted. These will be presented at national

and International Conferences and Congresses. The review for NASA entitled: “Spike and Jet Nosed Bodies in

Supersonic Flow” is in the final stage of preparation. (3) Submission of Proposals and White Papers: An

unsolicited proposal to the NASA GRC, 4 Notices of Intent, two White Papers to NASA and two proposals to

the CRDF. (4) Theory and numerical simulations: Analytical theory, numerical simulation, comparison of

theoretical with experimental results, and modification of theoretical approaches, models, grids etc. have been

conducted for several complicated 2D and 3D nozzle and inlet designs using NASA and IM/MSU codes based

on marching and full Euler and Navier-Stokes solvers: CFL3D, VULCAN, GODUNOV, and others. (5) Experimental tests and student training: The course: “Advanced Aerodynamics and Aircraft Performance” was presented in the fall semester, 2001; training and experimental tests using the HU LSWT. (6) Improvement of the

FM&AL computer system: installation of third generation software TECPLOT 9.0 for the UNIX SGI workstation,

NASA software “Alchemize” as a support for the NASA codes: GRIDGEN, CFL3D and VULCAN and others.

(7) Student Research Activity: Involvement of two graduate and one undergraduate students as research

assistants in the current research project fulfillment. Note that this research by the FM&AL research team was

conducted jointly with the team working on another project under the NASA grant NAG–2249. Therefore

outcomes for both projects are partially the same.

ABSTRACT

A laboratory implementation of a fuzzy logic-tracking controller using a low cost Motorola

MC68HC11E9 microprocessor is described in this report. The objective is to design the most

optimal yet practical controller that can be implemented and marketed, and which gives respectable performance, even when the system loads, inertia and parameters are varying. A distinguishing feature of this work is the by-product goal of developing a marketable, simple,

functional and low cost controller. Additionally, real-time nonlinearities are not ignored, and a

mathematical model is not required. A number of components have been designed, built and

tested individually, and in various combinations of hardware and software segments. These

components have been integrated with a brushless motor to constitute the drive system. A

microprocessor-based FLC is incorporated to provide robust speed and position control. Design

objectives that are difficult to express mathematically can be easily incorporated in a fuzzy logicbased controller by linguistic information (in the form of fuzzy IF-THEN rules). The theory and

design are tested in the laboratory using a hardware setup. Several test cases have been conducted to confirm the effectiveness of the proposed controller. The results indicate excellent

tracking performance for both speed and position trajectories. For the purpose of comparison,

a bang-bang controller has been tested. The fuzzy logic controller performs significantly better

than the traditional bang-bang controller. The bang-bang controller has been shown to be

relatively inaccurate and lacking in robustness. Description of the implementation hardware

system is also given.

ABSTRACT

Solar energy is a renewable, nonpolluting, and most abundant energy source for human

exploration of a remote site or outer space. In order to generate appreciable electrical power in

space or on the earth, it is necessary to collect sunlight from large areas and with high efficiency

due to the low density of sunlight. Future organic or polymer (plastic) solar cells appear very

attractive due to their unique features such as light weight, flexible shape, tunability of energy

band-gaps via versatile molecular or supramolecular design, synthesis, processing and device

fabrication schemes, and much lower cost on large scale industrial production. It has been

predicted that supramolecular and nano-phase separated block copolymer systems containing

electron rich donor blocks and electron deficient acceptor blocks may facilitate the charge carrier

separation and migration due to improved electronic ultrastructure and morphology in comparison to polymer composite system. This presentation will describe our recent progress in the

design, synthesis and characterization of a novel block copolymer system containing donor and

acceptor blocks covalently attached. Specifically, the donor block contains an electron donating

alkyloxy derivatized polyphenylenevinylene (RO-PPV), the acceptor block contains an electron

withdrawing alkyl-sulfone derivatized polyphenylenevinylene (SF-PPV). The key synthetic strategy includes the synthesis of each individual block first, then couple the blocks together. While

the donor block has a strong PL emission at around 560 nm, and acceptor block has a strong

PL emission at around 520 nm, the PL emissions of final block copolymers are severely

quenched. This verifies the expected electron transfer and charge separation due to interfaces

of donor and acceptor nano phase separated blocks. The system therefore has potential for

variety light harvesting applications, including high efficient photovoltaic applications.

An Innovative Manufacturing of CCC Ion Thruster Grids by

North Carolina A&T’s RTM Carbon/Carbon Process

ABSTRACT

Electric ion thrusters are the preferred engines for deep space missions, because of very

high specific impulse. The ion engine consists of screen and accelerator grids containing thousands of concentric very small holes. The xenon gas accelerates between the two grids, thus

developing the impulse force. The dominant life-limiting mechanism in the state-of-the-art molybdenum thrusters is the xenon ion sputter erosion of the accelerator grid. Carbon/carbon composites (CCC) have shown to be have less than 1/7 the erosion rates than the molybdenum, thus for

interplanetary missions CCC engines are inevitable. Early effort to develop CCC composite

thrusters had a limited success because of limitations of the drilling technology and the damage

caused by drilling. The proposed is an in-situ manufacturing of holes while the CCC is made.

Special low CTE molds will be used along with the NC A&T’s patented resin transfer molding

(RTM) technology to manufacture the CCC grids. First, a manufacture process for 10-cm diameter thruster grids will be developed and verified. Quality of holes, density, CTE, tension, flexure,

transverse fatigue and sputter yield properties will be measured. After establishing the acceptable quality and properties, the process will be scaled to manufacture 30-cm diameter grids. The

properties of the two grid sizes are compared with each other.

Carbon Fiber Reinforced Ceramic Composites for Propulsion Applications

Kunigal N. Shivakumar

North Carolina A&T State University

Center for Composite Materials Research

Fort IRC Building, Room 205

1601 East Market Street

Greensboro, North Carolina 27411

ABSTRACT

Fiber reinforced ceramic composites are materials of choice for gas turbine engines because

of their high thermal efficiency, thrust/weight ratio, and operating temperatures. However, the

successful introduction of ceramic composites to hot structures is limited because of excessive

cost of manufacturing, reproducibility, nonuniformity, and reliability. Intense research is going on

around the world to address some of these issues. The proposed effort is to develop a comprehensive status report of the technology on processing, testing, failure mechanics, and environmental durability of carbon fiber reinforced ceramic composites through extensive literature

study, vendor and end-user survey, visits to facilities doing this type of work, and interviews.

Then develop a cooperative research plan between NASA GRC and NCA&T (Center for Composite Materials Research) for processing, testing, environmental protection, and evaluation of

fiber reinforced ceramic composites.

ABSTRACT

This work is being conducted by the RF Microelectronics Laboratory in the Electrical Engineering Department at North Carolina A&T State University under NASA Grant No. NAG3–2584.

North Carolina State University at Raleigh, North Carolina is also participating in this research

supported by a subcontract. The work aims at developing a low-power SOI CMOS Transceiver

for deep-space communications. RF Receiver must accomplish the following tasks: (a) Select

the desired radio channel and reject other radio signals, (b) Amplify the desired radio signal and

translate them back to baseband, and (c) Detect and decode the information with Low BER. In

order to minimize cost and achieve high level of integration, receiver architecture should use

least number of external filters and passive components. It should also consume least amount

of power to minimize battery cost, size, and weight. One of the most stringent requirements

for deep-space communication is the low-power operation. Our study identified that two candidate architectures listed in the following meet these requirements: (1) Low-IF receiver,

(2) Subsampling receiver. The low-IF receiver uses minimum number of external components.

Compared to Zero-IF (Direct conversion) architecture, it has less severe offset and flicker noise

problems. The Subsampling receiver amplifies the RF signal and samples it using track-and-hold

Subsampling mixer. These architectures provide low-power solution for the short- range communications missions on Mars. Accomplishments to date include: (1) System-level design and

simulation of a Double-Differential PSK receiver, (2) Implementation of Honeywell SOI CMOS

process design kit (PDK) in Cadence design tools, (3) Design of test circuits to investigate

relationships between layout techniques, geometry, and low-frequency noise in SOI CMOS,

(4) Model development and verification of on-chip spiral inductors in SOI CMOS process,

(5) Design/implementation of low-power low-noise amplifier (LNA) and mixer for low-IF receiver,

and (6) Design/implementation of high-gain LNA for sub-sampling receiver. Our initial results

show that substantial improvement in power consumption is achieved using SOI CMOS as

compared to standard CMOS process. Potential advantages of SOI CMOS for deep-space

communication electronics include: (1) Radiation hardness, (2) Low-power operation, and

(3) System-on-Chip (SOC) solutions.

ABSTRACT

Methylene dianiline (MDA) and its derivatives have been used in the synthesis of polyimides

to yield polymers with characteristic low-density, high tensile strength, improved solubility in

organic solvents, low-melt viscosities and high thermal stability (> 550 °F) in air. Polyimides with

such properties are desirable for use in aerospace systems, e.g., jet engines, airframe, missiles,

and rockets where weight is critical. Recent research at Prairie View A&M University is focused

on developing monomers to generate polyimides with enhanced performance over that of

NASA’s PMR-15. The objective of this work is to synthesize three ring aromatic diamines which

are non-toxic and when reacted with the appropriate dianhydrides will yield polyimides with

lower viscosity, improve processability, good retention of mechanical properties, and oxidative

stability at high environmental temperatures. Modifications of the three ring aromatic diamines

include replacing the methylene linkages with aromatic ethers by nucleophilic aromatic substitution reactions and incorporating mono- and di-substituents to the center aromatic ring. An

update of current reactions involved in synthesis efforts to generate three ring aromatic monomers for polyimides with methylene, carbonyl, and ether linkages separating the aromatic

moieties will be displayed.

ABSTRACT

The under representation of African Americans and other minority groups in science and technology is well

known. No more so is this fact true than in the renewable energy industry. African Americans are essentially not

involved in the advanced energy industry, albeit they can contribute immensely to the growth of the industry due to

their cultural ties with developing countries where these emerging energy technologies find vast applications and

markets. Not only is there a need to empower HBCUs with the ability to prepare the communities they serve for full

participation in this emerging industry, but also HBCUs can play an important role in removing the impediment to a

widespread use of renewable energy in developing countries for the mutual benefit of United States energy industry

and the developing countries of Africa in particular. Because of their historical and cultural ties with Africa, these

institutions can be very effective in training personnel from African and other developing countries to produce a cadre

of trained and certified technicians of distributed energy technology. Furthermore, the graduates of HBCUs trained in

this field could be very effective in marketing U.S. energy technologies in the rapidly growing markets of emerging

democracies. Even though several generically designed programs have been enacted to encourage and enhance the

diversification of our technological workforce, with some success, there is a need for a focused effort to include the

under represented segments of our society at the early stages of the emergence of distributed energy technologies.

An effective means for building the capacity of minority populations to participate in this industry would be the

introduction of relevant renewable energy courses in the curricula of HBCUs and Mls. A necessary first step is the

design and pilot teaching of a select number of courses in distributed energy technologies. For this reason, Savannah

State University (SSU), an HBCU, in partnership with the Florida Solar Energy Center (FSEC) chose to focus on

course design as part of the RE SCADA/Training project. Leveraging additional funding by the National Science

Foundation (NSF), SSU and FSEC in collaboration with Brevard Community College (BCC) will design fully integrated, industry-based course curricula for training certified technicians that will address the emerging distributed

energy commercial and residential needs. The curricula to be produced will address the following advanced energy

technologies: Building Trades, Photovoltaics, Microturbines, Fuel Cells, Solar Thermal, Distributed Generation, and

Combined Heat and Power. Towards this end, the following five distributed energy courses are under development:

Introduction to Distributed Energy Technology, Energy Efficient Buildings, Alternative Fuels and Electric Vehicle

Technology, Solar Thermal Technologies, and Distributed Electric Power Generation and Storage.

ABSTRACT

The NASA Glenn Research Center (GRC) funded the 2001–2002 Tennessee State University (TSU) Research Project for increasing the pool of minority engineers. The NASA GRC/TSU

Research Project is designed to develop a cadre of SMET professionals who have academic

and research expertise in technical areas of interest to NASA, in addition to having some familiarity with the mission of the NASA Glenn Research Center. The goal of increasing minority

participation in SMET disciplines was accomplished by: (1) introducing and exposing 96 minority

youth to SMET careers and to the required high school preparation necessary to make high

school graduation, college attendance and engineering careers a reality through the campus

based pre-college SMET program: Minority Introduction to Engineering (MITE); (2) by providing

financial support through scholarships for four (4) TSU engineering students to NASA; (3)

familiarization with the SMET profession and with NASA through summer internships at NASA

GRC for two TSU NASA Glenn Research Scholars; and experiences through research internships at NASA GRC.

A Nonlinear Model for Fuel Atomization in Spray Combustion

Essam A. Ibrahim and Dave Sree

Tuskegee University

Department of Mechanical Engineering

Tuskegee, Alabama 36088

ABSTRACT

Most gas turbine combustion codes rely on ad-hoc statistical assumptions regarding the

outcome of fuel atomization processes. The modeling effort proposed in this project is aimed at

developing a realistic model to produce accurate predictions of fuel atomization parameters. The

model involves application of the nonlinear stability theory to analyze the instability and subsequent disintegration of the liquid fuel sheet that is produced by fuel injection nozzles in gas

turbine combustors. The fuel sheet is atomized into a multiplicity of small drops of large surface

area to volume ratio to enhance the evaporation rate and combustion performance. The proposed model will effect predictions of fuel sheet atomization parameters such as drop size,

velocity, and orientation as well as sheet penetration depth, breakup time and thickness. These

parameters are essential for combustion simulation codes to perform a controlled and optimized

design of gas turbine fuel injectors. Optimizing fuel injection processes is crucial to improving

combustion efficiency and hence reducing fuel consumption and pollutants emissions.

Tuskegee, Alabama 36088

ABSTRACT

In the first year of this research, we successfully synthesized and characterized Polymer/

Layered Silicate nanocomposite using the polyimide PMR-15 as the polymer and several layered silicate nanoparticles. We have scaled up the process to allow fabrication of monoliths

using these nanocomposites. The morphology of these systems was found to evolve during

processing to an exfoliated structure for one system and intercalated for the rest. Correlation

with Transmission Electron Microscopy studies is underway. Dynamic mechanical analysis

(DMA) results showed a significant increase in the thermomechanical properties (E ́ and E ́ ́) of

2.5 wt.% clay loaded nanocomposites in comparison to the neat polyimide. Increasing the clay

loading to 5 wt.% decreased these properties. Higher glass transition temperatures were observed for 2.5 wt.% nanocomposites compared to the neat polyimide. A lower coefficient of

thermal expansion was observed only for the PGV/PMR-15 nanocomposite. An improvement in

the flexural properties (modulus, strength and elongation) was observed for the 2.5 wt.%

nanocomposite but not for the 5 wt.% nanocomposites. The improved barrier properties polymer/silicate nanocomposites suggest that moisture uptake should be decreased for PMR-15

nanocomposites. The results of some recent experiments to examine delineate the ability of the

silicate nanoparticles in improving the hydrolytic degradation of PMR-15 will be discussed.

Computational Methods for Jet Noise Simulation

University of New Mexico

415 Humanities Building

Albuquerque, New Mexico 87131

ABSTRACT

The purpose of our project is to develop, analyze, and test novel numerical technologies

central to the long term goal of direct simulations of subsonic jet noise. Our current focus is on

two issues: accurate, near-field domain truncations and high-order, single-step discretizations of

the governing equations. The DNS of jet noise poses a number of extreme challenges to computational technique. In particular, the problem involves multiple temporal and spatial scales as

well as flow instabilities and is posed on an unbounded spatial domain. Moreover, the basic

phenomenon of interest, the radiation of acoustic waves to the far field, involves only a minuscule fraction of the total energy. The best current simulations of jet noise are at low Reynolds

number. It is likely that an increase of one to two orders of magnitude will be necessary to reach

a regime where the separation between the energy-containing and dissipation scales is sufficient to make the radiated noise essentially independent of the Reynolds number. Such an

increase in resolution cannot be obtained in the near future solely through increases in computing power. Therefore, new numerical methodologies of maximal efficiency and accuracy are

required.

Characterizing Non-Uniformity of Performance of Thin-Film Solar Cells

Gregory B. Lush

University of Texas at El Paso

Department of Electrical and Computer Engineering

El Paso, Texas 79968

ABSTRACT

Thin-film Solar Cells are being actively studied for terrestrial and space applications because

of their potential to provide low-cost, lightweight, and flexible electric power system. Currently,

thin-film solar cell performance is limited partially by the nonuniformity of performance that they

typically exhibit. This nonuniformity of performance necessitates more detailed characterization

techniques than the well-known macroscopic measurements such as current-voltage and

efficiency. This project seeks to explore methods of characterization that take into account the

spatial nonuniformity of thin-film solar cells. In this presentation we show results of electroluminescence images, short-circuit maps, and Kelvin Probe maps. All these mapping characterization and analysis tools show that the non-uniformities can correlated with device performance

and efficiency.

Structural Reliability Using Probability Density Estimation Methods Within NESSUS

Cody Ric Godines

University of Texas at San Antonio

4900 North Loop, 1604 West

San Antonio, Texas 78249

ABSTRACT

A reliability analysis studies a mathematical model of a physical system taking into account

uncertainties of design variables and common results are estimations of a response density,

which also implies estimations of its parameters. Some common density parameters include the

mean value, the standard deviation, and specific percentile(s) of the response, which are measures of central tendency, variation, and probability regions, respectively. Reliability analyses are

important since the results can lead to different designs by calculating the probability of observing safe responses in each of the proposed designs. All of this is done at the expense of added

computational time as compared to a single deterministic analysis which will result in one value

of the response out of many that make up the density of the response. Sampling methods, such

as monte carlo (MC) and latin hypercube sampling (LHS), can be used to perform reliability

analyses and can compute nonlinear response density parameters even if the response is

dependent on many random variables. Hence, both methods are very robust; however, they are

computationally expensive to use in the estimation of the response density parameters. Both

methods are 2 of 13 stochastic methods that are contained within the Numerical Evaluation of

Stochastic Structures Under Stress (NESSUS) program. NESSUS is a probabilistic finite element analysis (FEA) program that was developed through funding from NASA Glenn Research

Center (GRC). It has the additional capability of being linked to other analysis programs; therefore, probabilistic fluid dynamics, fracture mechanics, and heat transfer are only a few of what is

possible with this software. The LHS method is the newest addition to the stochastic methods

within NESSUS. Part of this work was to enhance NESSUS with the LHS method. The new LHS

module is complete, has been successfully integrated with NESSUS, and been used to study

four different test cases that have been proposed by the Society of Automotive Engineers (SAE).

The test cases compare different probabilistic methods within NESSUS because it is important

that a user can have confidence that estimates of stochastic parameters of a response will be

within an acceptable error limit. For each response, the mean, standard deviation, and

0.99 percentile, are repeatedly estimated which allows confidence statements to be made for

each parameter estimated, and for each method. Thus, the ability of several stochastic methods

to efficiently and accurately estimate density parameters is compared using four valid test cases.

While all of the reliability methods used performed quite well, for the new LHS module within

NESSUS it was found that it had a lower estimation error than MC when they were used to

estimate the mean, standard deviation, and 0.99 percentile of the four different stochastic

responses. Also, LHS required a smaller amount of calculations to obtain low error answers with

a high amount of confidence than MC. It can therefore be stated that NESSUS is an important

reliability tool that has a variety of sound probabilistic methods a user can employ and the

newest LHS module is a valuable new enhancement of the program.

CARET (Consortium for Advancing Renewable Energy Technology)

1055 North Bickett Road

Wilberforce, Ohio 45384

ABSTRACT

The Student Outreach with Renewable Energy Technology (SORET) program is a joint grant

that involves a collaboration between three HBCU’s (Central State University, Savannah State

University, and Wilberforce University) and NASA John H. Glenn Research Center at Lewis

Field. The overall goal of the grant is to increase the interest of minority students in the technical

disciplines, to encourage participating minority students to continue their undergraduate study in

these disciplines, and to promote graduate school to these students. As a part of SORET,

Central State University has developed an undergraduate research associates program over the

past two years. As part of this program, students are required to take special laboratory courses

offered at Wilberforce University that involve the application of renewable energy systems. The

course requires the students to design, construct, and install a renewable energy project. In

addition to the applied renewable energy course, Central State University provided four undergraduate research associates the opportunity to participate in summer internships at Texas

Southern University (Renewable Energy Environmental Protection Program) and the Cleveland

African-American Museum (Renewable Energy Summer Camp for High School Students) an

activity cosponsored by NASA and the Cleveland African-American Museum. Savannah State

University held a high school summer program with a theme of “the Direct Impact of Science on

Our Every Day Lives.” The purpose of the institute was to whet the interest of students in science, mathematics, engineering, and technology (SMET) by demonstrating the effectiveness of

science to address real world problems. The 2001 institute involved the design and installation of

a PV water pumping system at the Center for Advanced Water Technology and Energy Systems

at Savannah State. Both high school students and undergraduates contributed to this project.

Wilberforce University has used NASA support to provide resources for an Applied Renewable

Energy Laboratory offered to both Central State and Wilberforce students. In addition, research

endeavors for high school and undergraduates were funded during the summer. The research

involved attempts to layer photovoltaic materials on a conducting polymer (polypyrrole) substrate. Two undergraduate students who were interested in polymer research originated this

concept. Finally, the university was able to purchase a meteorological station to assist in the

analysis of the solar/wind hybrid power system operating at the university.

Generic Divide and Conquer Internet-Based Computing

*Presently with Chapman University, Orange, California

ABSTRACT

The growth of Internet-based applications and the proliferation of networking technologies

have been transforming traditional commercial application areas as well as computer and

computational sciences and engineering. This growth stimulates the exploration of Peer to Peer

(P2P) software technologies that can open new research and application opportunities not only

for the commercial world, but also for the scientific and high-performance computing applications community. The general goal of this project is to achieve better understanding of the

transition to Internet-based high-performance computing and to develop solutions for some of

the technical challenges of this transition. In particular, we are interested in creating long-term

motivation for end users to provide their idle processor time to support computationally intensive

tasks. We believe that a practical P2P architecture should provide useful service to both clients

with high-performance computing needs and contributors of lower-end computing resources. To

achieve this, we are designing dual-service architecture for P2P high-performance divide-andconquer computing; we are also experimenting with a prototype implementation. Our proposed

architecture incorporates a master server, utilizes dual satellite servers, and operates on the

Internet in a dynamically changing large configuration of lower-end nodes provided by volunteer

contributors. A dual satellite server comprises a high-performance computing engine and a

lower-end contributor service engine. The computing engine provides generic support for divideand-conquer computations. The service engine is intended to provide free useful HTTP-based

services to contributors of lower-end computing resources. Our proposed architecture is complementary to and accessible from computational grids, such as Globus, Legion, and Condor. Grids

provide remote access to existing higher-end computing resources; in contrast, our goal is to

utilize idle processor time of lower-end Internet nodes. Our project is focused on a generic divide

and conquer paradigm and on mobile applications of this paradigm that can operate on a loose

and ever changing pool of lower-end Internet nodes.

P2P Technology for High-Performance Computing: An Overview

Jason Berry

Winston-Salem State University

601 Martin Luther King Jr. Drive

Winston-Salem, North Carolina 27110

ABSTRACT

The transition from cluster computing to peer-to-peer (P2P) high-performance computing

has recently attracted the attention of the computer science community. It has been recognized

that existing local networks and dedicated clusters of headless workstations can serve as

inexpensive yet powerful virtual supercomputers. It has also been recognized that the vast

number of lower-end computers connected to the Internet stay idle for as long as 90% of the

time. The growing speed of Internet connections and the high availability of free CPU time

encourage exploration of the possibility to use the whole Internet rather than local clusters as

massively parallel yet almost freely available P2P supercomputer. As a part of a larger project

on P2P high-performance computing, it has been my goal to compile an overview of the 2P2

paradigm. I have studied various P2P platforms and I have compiled systematic brief descriptions of their most important characteristics. I have also experimented and obtained hands-on

experience with selected P2P platforms focusing on those that seem promising with respect to

P2P high-performance computing. I have also compiled relevant literature and web references.

I have prepared a draft technical report and I have summarized my findings in a poster paper.

Cost Management

CD-02-81965

Checking account analogy

• Code R Policy allows 2 months of forward funding

on contracts (beyond 9/30) and a carryover of 30%

of your budget allocation to cover expenditures

in the following fiscal year.

• How many months of forward funding do you

maintain in your personal checking account?

• Flight centers and major agency programs

operate with less than 2 weeks of forward

funding into the following fiscal year

• External audit organizations can't understand

why we ask for funds in our budget request that

we won't spend in the current fiscal year

Cost Management

CD-02-81966

Checking account analogy

• NASA MUREP

• At least 80% of funds should be costed by the end

of Federal fiscal year (September 30)

• NASA MUREP Grantees

• Incremental funding of large $ value grants or

cooperative agreements

• Minimize forward funding beyond 2 months into

the following fiscal year

• 100% of funds should be encumbered by the end

of the grant year; funds not encumbered will be

deducted from the first incremental funding,

actual carryover will be deducted from the second

incremental funding

How can I Improve My Program's Cost Performance?

CD-02-81967

RB Recommendations

1. Timelier initiation of procurements

– "Long lead time" acquisitions (1st qtr)

– Planning PR's / initiations use while awaiting 506 (1st qtr)

– Small purchases / off-the-shelf buys (2nd qtr)

– Tasks on support service contracts (1st half of year)

2. Expanded use "Incremental Funding" of contracts

– Recommended 2 actions per year (1-1st qtr; 2-midyear)

– Avoid multi year / 100% funding up-front scenarios

– Use incremental funding on major fixed-price contracts also

3. Limit forward funding on incrementally-funded contracts

(or major tasks on support service contracts) to only one month

4. Implement a one-time adjustment to start dates on major grants/

contracts that are not incrementally funded (startup in 1st qtr,

NOT 4th qtr)

5. Ensuring that all legitimate accrued cost on your program is

recorded in your Center fiscal systems in a timely and accurate

manner

6. Base budget requests upon how much $ your program will be

able to cost over the 12/1/97 – 12/1/98 time frame
42

GRC HBCU’s/OMU’s RESEARCH CONFERENCE

NASA/TM—2003-212207

Recommendation

CD-02-81968

• Submit all necessary information billing to your college

finance, accounting, or billing offices on a timely basis

(at least once per month)

• Insure that your college billing office submits required

billing information to NASA Glenn each month so that

Glenn may properly reflect accurate up-to-date costing

on your HBCU grant
