93 -- EROSION RESISTANT TPS TEST SAMPLES SOL RFQ2-36685-SLC DUE 092998 POC Sharon L. Connolly, Contracting Officer, Phone (650) 604-6927, Fax (650) 604-4646, Email sconnolly@mail.arc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/ARC/date.html#RFQ2-36685-SLC. E-MAIL: Sharon L. Connolly, sconnolly@mail.arc.nasa.gov. NASA Ames Research Center plans to issue a Request for Quotation for ten (10) each of the Erosion Resistant TPS test samples which will be tested in the arc jet facility in late 1998. This procurement is being conducted under the Simplified Acquisition Procedure (SAP). NASA Ames Research Center intends to purchase test samples of the Erosion Resistant TPS from HC Chem Research and Services Corporation at 15211 Sky View Drive, San Jose, CA 95129 on a sole source basis in accordance with 10 U.S.C 2304 (c)(1). This material will be used in the development of the advanced operable thermal protection systems (TPS) including operable leading edge TPS materials. Material will be capable of providing protection to a spacecraft against high heating up to 32000F at the outer surface and insulate the spacecraft interior structure and keep it below 3500F. The material will also be capable of providing protection against subsonic speed impact from fine dust particles as well as rain droplets. The desired erosion resistant properties will allow the spacecraft to fly through rain, fog and other severe weather conditions. The materials will consist of the Silicone Impregnated Reusable Ceramic Ablator with a 2D carbon-carbon face sheet and/or other material with similar characteristics to provide resistance against the subsonic impact from dust particles and rain droplets at the surface. The model will be in a leading edge configuration with maximum dimensions of 10 inches in length, 1.5 inches radius for the leading edge and minimum of 1.2 inches thick. These samples will be subjected to a simulated entry heating environment that is similar to those experienced by a spacecraft during the descent phase. After testing in the heating environment, the test samples will be subjected to the erosion test such as the Rain Facility at Wright Patterson Air Force Base and/or the flight testing on the F-15. The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 15 days from the publication of this synopsis to submit their qualifications/capabilities in writing to the identified point of contact. 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 15 days or without the required information will be considered nonresponsive 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 communication is 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 -- See Internet Note "B" Posted 09/15/98 (D-SN250159). (0258)
