A -- "AEROPROPULSION BASE RESEARCH AND TECHNOLOGY" The NRA will be available electronically on the date of April 30, 1999 via "http://nais.msfc.nasa.gov/EPS/GRC/date.html". Prospective Offerors are requested to submit a Letter of Intent by May 7, 1999 to Mr. Peter McCallum. The letter should address: Institution or Organization Name; PI and CoPI names and address; title of proposal; telephone number; fax number; email address; and a brief summary of what you plan to propose (limit 3000 characters). The NASA Glenn Research Center is interested in receiving proposals, solely for grants or cooperative agreements, for Aeropropulsion Base Research and Technology. Proposal submissions are specifically sought from educational institutions and other nonprofit organizations. Although no specific set-aside is comtemplated for HBCU's or other minority institutions, their participation is highly encouraged. NASA is encouraging partnering and teaming arrangements with NASA centers and other U.S. Government Agencies. NOTE: Educational institutions and nonprofit organizations shall be the primary/lead grantee. A continued 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, hybrid propulsion systems, or propulsion system components. 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. The research effort is intended to deliver further progress toward the Agency's 9 Aeronautics and Space Transportation goals. (1. Safety; 2. Emissions; 3. Noise; 4. Capacity; 5. Affordability; 6. High Speed; 7. General Aviation; 8. Design Tools and Experimental Aircraft, and; 9. Low-Cost Space Access) NASA anticipates making between 20 and 30 awards as a result of this NRA totaling approximately $2 to $3 million. Questions related to this NRA in the areas of preparation, submission or technical concerns shall be submitted in writing to Ms. Irene Cierchacki no later than May 31, 1999. Responses to questions will be posted on the website noted. Proposals must be received on or before COB June 14, 1999. Proposals received after this date shall be rejected.
