99 -- RESEARCH AND DEVELOPMENT FOR LOW-SPEED ENGINE ANALYSIS FOR HYPER-NEXT SOL 1-168-LA.1185 DUE 081799 POC Kimberly D. Duncan, Contracting Officer, Phone (757) 864-3566, Fax (757) 864-8863, Email k.d.duncan@larc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LaRC/date.html#1-168-LA.1185. E-MAIL: Kimberly D. Duncan, k.d.duncan@larc.nasa.gov. NASA/LaRC plans to issue a Request for Quotation (RFQ) for research and development for low-speed engine analysis for Hyper-NEXT. Evaluate potential advanced turbo-ramjet cycles to provide the takeover speeds for the dual-mode ram-scram engine. This cycle analysis and scaling studies shall include the Air Core Enhanced Turbo-Ramjet (AceTR) and its derivatives. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/LaRC intends to purchase the items from Pratt & Whitney, West Palm Beach, FL, unique services available from only one source. The Air Core Enhanced Turbojet (AceTR) and its derivatives are central to the engine matrix of the proposed study to define the turbine cycle most suited for hypersonic airplanes and airbreathing launch vehicles in a single-stage for unassisted horizontal takeoff because of its promise of high-thrust-per-unit cross section and high thrust-to-weight ratio. The AceTR concept is proprietary to Pratt & Whitney. Pratt & Whitney is the only company that has been focusing on high thrust-to-weight and high-thrust-per-unit cross section engine concepts. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 15 days or without the required information will be considered non-responsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
