					 APPENDIX A
					NRA-97-LeRC-2
			AEROPROPULSION BASE RESEARCH AND TECHNOLOGY


A continuing demand exists for improved air breathing engines to power a wide range of advanced 
aerospace vehicles in all speed ranges - subsonic including general aviation aircraft, supersonic, and 
hypersonic.  Proposals are invited for research topics that will open the paths to innovative concepts for 
new or improved air breathing propulsion systems or propulsion system components.  Propulsion system 
components include inlets, propellers, fans, compressors, combustors, turbines, nozzles, and recuperators 
and/or regenerators.  Objectives include greater component and cycle efficiency; lower gaseous and 
particulate emissions; reduced coolant penalties through advanced cooling concepts; reduced noise levels; 
and reduced weight, volume, and aerodynamic drag.  Improvements in thermodynamic cycles and 
component aerodynamics, acoustics, structures technologies, combustion technologies and aircraft icing 
are sought.  In addition, innovative concepts are sought for analysis, design, and measurement technology 
which will significantly reduce design cycle time with improved design quality in aeropropulsion systems 
for low subsonic through hypersonic speeds.


FLUIDS

Improved air-breathing engines will require a clearer understanding of the basic flow physics of 
propulsion system components, improved numerical models and design tools, and innovative concepts 
which apply that knowledge.  Areas of interest include:

Inlets and nozzles: Research that will lead to concepts which will result in higher performance, quieter, 
shorter, lighter weight inlets and nozzles.  Advanced steady-state and time-dependent flow analyses and 
benchmark quality data for flow fields including shocks, boundary layers, boundary-layer control, 
separation, heat transfer, surface cooling and jet mixing.

Turbomachinery: Research that will lead to concepts which will allow increased efficiency, fewer 
compressor and turbine stages for core engines, lower fan noise, and improved turbine cooling.  Advanced 
flow codes, physical models, and supporting validation data for both steady and unsteady flows including 
shocks, viscous effects, heat transfer, and tip-clearance effects in fans, compressors, and turbines.  Novel 
concepts for instrumentation and flow visualization.

Combustors and augmentors: Research that will lead to concepts which will reduce emissions and 
combustor cooling requirements.  Highly efficient flow codes and novel measurement techniques for the 
flows and physical processes in a combustor, including fuel injection, spray evaporation and mixing, 
reaction mechanisms and kinetic rates for hydrocarbon oxidation and soot formation, formation of solid 
and gaseous exhaust emissions, and the effects of endothermic fuels in high-speed systems.
Drive Train Technology: Research that will lead to concepts which would decrease gearbox and drive 
system weight, or increase strength and reliability, or reduce noise.  High temperature gear, bearing and 
seal materials, improved tooth forms, prediction methods for gear noise, elastohydrodynamic film 
thickness for contacting teeth, and transmission health monitoring systems.

Computational Methods for Internal Flows: Algorithms utilizing high-order upwind techniques, 
unstructured and solution-adaptive grid schemes.  New methods for surface modeling and grid generation.  
Software strategies to simplify the parallel implementation of the above methodologies.

Acoustics/Aircraft Noise Reduction: Research that will lead to concepts which will reduce the noise of 
propulsion systems including engine noise components such as the fan, jet, and combustor.  Advanced 
computational aeroacoustics codes for noise generation, propagation in engine ducts, and radiation to the 
far field.  Diagnostic techniques and experiments for mechanism identification and source location such 
as microphone arrays and signal processing algorithms.  Active noise control concepts and 
implementation strategies.

Propulsion System Numerical Simulation: Methods for integrated system analyses that couple parts, 
components, subsystems and systems at appropriate levels of detail to minimize the time and cost of 
performing large scale simulations are required.  For example, coupling a 1-D or axisymmetric engine 
simulation to a 3-D compressor or combustor simulation to capture the effects of inlet distortion, 
unsteadiness and non-uniform exit profiles on overall engine performance and operability.  Techniques 
that efficiently utilize affordable, high-performance, massively parallel computer systems to simulate 
engine performance rapidly are also required.

Aircraft and Engine Icing: Fundamental research in aircraft icing physics and effects of icing.  Innovative 
concepts in icing test techniques including scaling and instrumentation issues.  Analytical and 
computational work for predicting ice accretion (droplet trajectories, ice growth and removal).  New 
methodologies for aircraft ice protection and sensors are also of interest.


MATERIALS

Innovative research topics are sought for high temperature materials for aeropropulsion applications. The 
proposed efforts should be focused on new material concepts and/or on critical issues currently impeding 
the use of high temperature polymer composites, nickel-base superalloys, high temperature intermetallics, 
ceramic matrix composites, environmentally protective coatings, thermal barrier coatings, and self-
lubricating wear resistant coatings for long life applications.

The fundamental issues of processing-microstructure-property relationships for long-life uses of all of 
these materials is of primary interest. Low cost, innovative processing techniques for composites and 
reinforcing fibers and fiber coatings are also of interest. Computational modeling of materials
and processes are also of interest.


STRUCTURES

Innovative grant proposals are sought on Structures for Aero-Propulsion. Some of the Structures Research 
will be covered under the Hi TEMP NRA solicitation:  NRA-97-LeRC-1.

Machine Dynamics:  Analytical and experimental research that will advance the state-of-the-art in 
Aeroelasticity of fans, compressors, and turbines.  In addition, concepts are sought for active and passive 
blade vibration control and active rotor control of engine stall (e.g. magnetic rotor suspension).
 
Mechanical Components:  Research that will lead to concepts which would improve efficiency, increase 
reliability, reduce cost, increase power density, or reduce noise for aircraft propulsion systems.  High 
temperature seals, advanced bearings, gears, lubrication systems, and health monitoring systems.

Structural Mechanics:  Research that will enable innovative structural concepts and design/analysis 
procedures for engine components, with an emphasis on accounting for multidisciplinary effects, 
quantifying effects of uncertainty of critical design parameters, optimizing performance, designing
for life-cycle reliability and cost, and computational methods for tailored composite materials and 
structural components for optimum performance.

Life Prediction:  Research that will develop life-prediction models and failure theories for advanced high 
temperature materials including their fatigue and fracture characteristics.  In Test and Evaluation, 
benchmark structural testing and non-destructive evaluation of advanced materials is desired as well the 
evaluation of failure modes in critical components that use advanced materials.


INSTRUMENTATION AND CONTROLS TECHNOLOGY

The following technical areas are of particular interest to NASA LeRC.  Innovative concepts which have 
potential for technology gap breakthroughs are also encouraged.

Propulsion research instrumentation is needed to support a wide variety of experimental efforts that range 
from fundamental studies of basic phenomena and design code validation to complete engine systems 
tests.  These instrumentation efforts should focus on both miniature in-situ sensors (including thin film 
sensors) and nonintrusive remote sensing measurement systems.  Special interest is placed on techniques 
useful in conjunction with advanced propulsion system materials such as ceramics and composites, and 
optical techniques which provide measurements both on and off model of multiple parameters at multiple 
spatial points in order to provide 2D and 3D data of propulsion-related phenomena.

Advanced controls are needed to achieve maximum levels of propulsion system performance and life 
while maintaining adequate safety margins.  The controls efforts should focus on the development of 
integrated flight/propulsion control systems, and on the development of active engine component control 
systems for improved stability, environmental impact and safety, using adaptive and intelligent control 
systems.  Efforts in integrated engine health management and fault detection are sought.  Other controls 
efforts focus on developing advanced point and optical sensors, including fiber-optic sensors, for use in 
aeropropulsion control systems.  Emerging technologies such as integrated optics and Micro-electro-
mechanical Systems (MEMS) for control, sensor, and actuator applications are of considerable interest.  

Dynamic modeling efforts should focus on unconventional concepts as well as on the coupling among 
propulsion-related disciplines such as controls, structures and materials.

Electronics that can operate at very high temperatures is an increasing need in aerospace systems for a 
wide variety of applications; silicon carbide-based electronics has high potential here.  The silicon carbide 
electronics efforts now focus on both materials development and device development, with a goal of 
developing a wide variety of integrated electronic circuits for high temperature and high power propulsion 
applications.


MULTIDISCIPLINARY DESIGN AND ANALYSIS

Computer simulation tools for modeling the cost and life-cycle performance of parts, components, 
subsystems and systems from material selection to end of useful life.  New approaches are required for 
coupling multidisciplinary phenomenon that interact at different length and time scales.  In addition, 
integrated strategies and tools are required for seamless transition from analysis to design to 
manufacturing.  This includes algorithms for component-specific design optimization/tailoring, expert 
systems/artificial intelligence applications for analysis/design process automation and advanced tools for 
manufacturing process modeling.  The implementation of these tools on affordable, high performance, 
parallel computing platforms is also of interest to enable reasonable turnaround times.

                       INSTRUCTIONS FOR RESPONDING TO

                        NASA RESEARCH ANNOUNCEMENTS

                                (JUNE 1995)

                                1. Foreword

a. These instructions apply to "NASA Research Announcements." The "NASA Research Announcement 
(NRA)" permits competitive selection of research projects in accordance with statute while preserving the 
traditional concepts and understandings associated with NASA sponsorship of research.

b. These instructions are Appendix I to 1870.203 of the NASA Federal Acquisition Regulation 
Supplement.

                                 2. Policy

a. Proposals received in response to an NRA will be used only for evaluation purposes. NASA does not 
allow a proposal, the contents of which are not available without restriction from another source, or any 
unique ideas submitted in response to an NRA to be used as the basis of a solicitation or in negotiation 
with other organizations, nor is a pre-award synopsis published for individual proposals.

b. A solicited proposal that results in a NASA award becomes part of the record of that transaction and 
may be available to the public on specific request; however, information or material that NASA and the 
awardee mutually agree to be of a privileged nature will be held in confidence to the extent permitted by 
law, including the Freedom of Information Act.

                                 3. Purpose

These instructions supplement documents identified as "NASA Research Announcements." The NRAs 
contain programmatic information and certain requirements which apply only to proposals prepared in 
response to that particular announcement. These instructions contain the general proposal
preparation information which applies to responses to all NRAs.

                          4. Relationship to Award

a. A contract, grant, cooperative agreement, or other agreement may be used to accomplish an effort 
funded in response to an NRA. NASA will determine the appropriate instrument.

b. Grants are generally used to fund basic research in educational and nonprofit institutions, while 
research in other private sector organizations is accomplished under contract. Contracts resulting from 
NRAs are subject to the Federal Acquisition Regulation and the NASA FAR Supplement (NHB 5100.4). 
Any resultant grants or cooperative agreements will be awarded and administered in accordance with the 
NASA Grant and Cooperative Agreement Handbook (NHB 5800.1).

                         5. Conformance to Guidance

a. NASA does not have mandatory forms or formats for responses to NRAs; however, it is requested that 
proposals conform to the guidelines in these instructions. NASA may accept proposals without discussion; 
hence, proposals should initially be as complete as possible and be submitted on the proposers' most 
favorable terms.

b. To be considered responsive, a submission must, at a minimum, present a specific project within the 
areas delineated by the NRA; contain sufficient technical and cost information to permit a meaningful 
evaluation; be signed by an official authorized to legally bind the submitting organization; not merely 
offer to perform standard services or to just provide computer facilities or services; and not significantly 
duplicate a more specific current or pending NASA solicitation.

address the evaluation factors in these instructions and any specific factors in the NRA. Any substantial 
collaboration with individuals not referred to in the budget or use of consultants should be described. 
Subcontracting significant portions of a research project is discouraged.

(2) When it is expected that the effort will require more than one year, the proposal should cover the 
complete project to the extent that it can be reasonably anticipated. Principal emphasis should be on the 
first year of work, and the description should distinguish clearly between the first year's work and work 
planned for subsequent years.

f. Management Approach. For large or complex efforts involving interactions among numerous 
individuals or other organizations, plans for distribution of responsibilities and arrangements for ensuring 
a coordinated effort should be described. Intensive working relations with NASA field centers that are not 
logical inclusions elsewhere in the proposal should be described.

g. Personnel. The principal investigator is responsible for supervision of the work and participates in the 
conduct of the research regardless of whether or not compensated under the award. A short biographical 
sketch of the principal investigator, a list of principal publications and any exceptional qualifications 
should be included. Omit social security number and other personal items which do not merit 
consideration in evaluation of the proposal. Give similar biographical information on other senior 
professional personnel who will be directly associated with the project.  Give the names and titles of any 
other scientists and technical personnel associated substantially with the project in an advisory capacity.  
Universities should list the approximate number of students or other assistants, together with information 
as to their level of academic attainment. Any special industry-university cooperative arrangements should 
be described.

h. Facilities and Equipment. (1) Describe available facilities and major items of equipment especially 
adapted or suited to the proposed project, and any additional major equipment that will be required. 
Identify any Government-owned facilities, industrial plant equipment, or special tooling that are proposed 
for use.

(2) Before requesting a major item of capital equipment, the proposer should determine if sharing or loan 
of equipment already within the organization is a feasible alternative. Where such arrangements cannot be 
made, the proposal should so state. The need for items that typically can be used for research and non-
research purposes should be explained.

i. Proposed Costs. (1) Proposals should contain cost and technical parts in one volume: do not use separate 
"confidential" salary pages. As applicable, include separate cost estimates for salaries and wages; fringe 
benefits; equipment; expendable materials and supplies; services; domestic and foreign travel; ADP 
expenses; publication or page charges; consultants; subcontracts; other miscellaneous identifiable direct 
costs; and indirect costs. List salaries and wages in appropriate organizational categories (e.g., principal 
investigator, other scientific and engineering professionals, graduate students, research assistants, and 
technicians and other non-professional personnel). Estimate all manpower data in terms of man-months 
or fractions of full-time.

(2) Explanatory notes should accompany the cost proposal to provide identification and estimated cost of 
major capital equipment items to be acquired; purpose and estimated number and lengths of trips planned; 
basis for indirect cost computation (including date of most recent negotiation and cognizant agency); and 
clarification of other items in the cost proposal that are not self-evident. List estimated expenses as yearly 
requirements by major work phases. (Standard Form 1411 may be used).

(3) Allowable costs are governed by FAR Part 31 and the NASA FAR Supplement Part 1831 (and OMB 
Circulars A-21 for educational institutions and A-122 for nonprofit organizations).

j. Security. Proposals should not contain security classified material. If the research requires access to or 
may generate security classified information, the submitter will be required to comply with Government
security regulations. 

k. Current Support. For other current projects being conducted by the principal investigator, provide title 
of project, sponsoring agency, and ending date.

l. Special Matters. (1) Include any required statements of environmental impact of the research, human 
subject or animal care provisions, conflict of interest, or on such other topics as may be required by the 
nature of the effort and current statutes, executive orders, or other current Government-wide guidelines.

(2) Proposers should include a brief description of the organization, its facilities, and previous work 
experience in the field of the proposal.  Identify the cognizant Government audit agency, inspection 
agency, and administrative contracting officer, when applicable.

                            8. Renewal Proposals

a. Renewal proposals for existing awards will be considered in the same manner as proposals for new 
endeavors. A renewal proposal should not repeat all of the information that was in the original proposal. 
The renewal proposal should refer to its predecessor, update the parts that are no longer current, and 
indicate what elements of the research are expected to be covered during the period for which support is 
desired. A description of any significant findings since the most recent progress report should be included. 
The renewal proposal should treat, in reasonable detail, the plans for the next period, contain a cost 
estimate, and otherwise adhere to these instructions.

b. NASA may renew an effort either through amendment of an existing contract or by a new award.

                                 9. Length

Unless otherwise specified in the NRA, effort should be made to keep proposals as brief as possible, 
concentrating on substantive material. Few proposals need exceed 15-20 pages. Necessary detailed 
information, such as reprints, should be included as attachments. A complete set of attachments is 
necessary for each copy of the proposal. As proposals are not returned, avoid use of "one-of-a-kind" 
attachments: their availability may be mentioned in the proposal.

                            10. Joint Proposals

a. Where multiple organizations are involved, the proposal may be submitted by only one of them. It 
should clearly describe the role to be played by the other organizations and indicate the legal and 
managerial arrangements contemplated. In other instances, simultaneous submission of related proposals 
from each organization might be appropriate, in which case parallel awards would be made.

b. Where a project of a cooperative nature with NASA is contemplated, describe the contributions 
expected from any participating NASA investigator and agency facilities or equipment which may be 
required. The proposal must be confined only to that which the proposing organization can commit itself. 
"Joint" proposals which specify the internal arrangements NASA will actually make are not acceptable as 
a means of establishing an agency commitment.

                             11. Late Proposals

A proposal or modification received after the date or dates specified in an NRA may be considered if the 
selecting official deems it to offer NASA a significant technical advantage or cost reduction.

                               12. Withdrawal

Proposals may be withdrawn by the proposer at any time. Offerors are requested to notify NASA if the 
proposal is funded by another organization or of other changed circumstances which dictate termination 
of evaluation.

                           13. Evaluation Factors

a. Unless otherwise specified in the NRA, the principal elements (of approximately equal weight) 
considered in evaluating a proposal are its relevance to NASA's objectives, intrinsic merit, and cost.

b. Evaluation of a proposal's relevance to NASA's objectives includes the consideration of the potential 
contribution of the effort to NASA's mission.

c. Evaluation of its intrinsic merit includes the consideration of the following factors, none of which is 
more important than any other:

(1) Overall scientific or technical merit of the proposal or unique and innovative methods, approaches, or 
concepts demonstrated by the proposal.

(2) Offeror's capabilities, related experience, facilities, techniques, or unique combinations of these which 
are integral factors for achieving the proposal objectives.

(3) The qualifications, capabilities, and experience of the proposed principal investigator, team leader, or 
key personnel critical in achieving the proposal objectives.

(4) Overall standing among similar proposals and/or evaluation against the state-of-the-art.

d. Evaluation of the cost of a proposed effort includes the realism and reasonableness of the proposed cost 
and available funds.

                         14. Evaluation Techniques

Selection decisions will be made following peer and/or scientific review of the proposals. Several 
evaluation techniques are regularly used within NASA. In all cases proposals are subject to scientific 
review by discipline specialists in the area of the proposal. Some proposals are reviewed entirely in-house, 
others are evaluated by a combination of in-house and selected external reviewers, while yet others are 
subject to the full external peer review technique (with due regard for conflict-of-interest and protection of 
proposal information), such as by mail or through assembled panels. The final decisions are made by a 
NASA selecting official. A proposal which is scientifically and programmatically meritorious, but not 
selected for award during its initial review, may be included in subsequent reviews unless the proposer 
requests otherwise.

                          15. Selection for Award

a. When a proposal is not selected for award, and the proposer has indicated that the proposal is not to be 
held for subsequent reviews, the proposer will be notified. NASA will explain generally why the proposal 
was not selected. Proposers desiring additional information may contact the selecting official who will 
arrange a debriefing.

b. When a proposal is selected for award, negotiation and award will be handled by the procurement office 
in the funding installation. The proposal is used as the basis for negotiation. The contracting officer may 
request certain business data and may forward a model contract and other information which will be of 
use during the contract negotiation.

                          16. Cancellation of NRA

NASA reserves the right to make no awards under this NRA and to cancel this NRA. NASA assumes no 
liability for cancelling the NRA or for anyone's failure to receive actual notice of cancellation. 
Cancellation may be followed by issuance and synopsis of a revised NRA, since amendment of an NRA is 
normally not permitted.
