A -- RADIATIVELY DRIVEN WIND TUNNEL CONCEPT EVALUATION POC Norman E. Scaggs, Project Engineer, WL/FIMO, (513) 255-6317. Notice of Contract Action for RADIATIVELY DRIVEN WIND TUNNEL CONCEPT EVALUATION. The Wright Laboratory, Flight Dynamics Directorate, Aeromechanics Division is contemplating the award of a 60 month program to conduct experimental studies, develop modeling, and assimilate relevant international expertise for the purpose of exploring the feasibility of a radiatively-driven hypersonic wind tunnel. This new wind tunnel concept was conceived by Princeton University in 1992 as an alternate to conventional approaches for hypersonic wind tunnels. Conventional hypersonic wind tunnels require very high temperatures in the plenum, which leads to rapid throat degradation and partially dissociated, contaminated air in the test section. The technical challenges associated with this project include: ultra-high pressure ()10,000 atmospheres) air generation and control, thermodynamic characterization and modeling of ultra-high pressure ()10,000 atmospheres) air, ultra-high pressure ()10,000 atmospheres) air expansion dynamics, experimental verification of the total ultra- high pressure ()10,000 atmospheres) air process, modeling and experimental validation of radiation and beam coupling into high pressure ()2,000 atmospheres) supersonic flow fields, including such issues as collisional spectral narrowing, radiative breakdown, chemical kinetic mechanisms, and flow quality, development and modeling of ultra-high energy laser, microwave and beam sources, development of new non-intrusive diagnostic capabilities for both qualitative and quantitative measurement of flow quality and system performance. Firms responding should indicate whether they are, or are not, a small business, a socially and economically disadvantaged business, a woman owned business, a historically black college or university, or minority institution. For this item the general definition to be used to determine whether your firm is small is as follows: ''A small business concern is a concern that is independently owned and operated, is not dominant in the field of operation in which it is bidding on government contracts and with its affiliates, the number of employees does not exceed 500 persons.'' SIC Code 8731 applies. ''Concern means any buiness entity organization for profit with a place of business in the United States, its possessions, Puerto Rico, or the Trust Territory of the Pacific Islands, including but not limited to an individual, partnership, corporation, joint venture, association or corporation.'' The Air Force reserves the right to consider a small business set-aside based upon responses hereto. Small business respondents should provide a statement of capabilities to assist the Air Force in making a set-aside decision. Large businesses are only required to submit a statement of interest to receive a copy of the Request for Proposal (RFP). All respondents shall include in any request their assigned Commercial and Government Entity Code. Respondents are further requested to indicate their status as a Foreign-owned/Foreign-controlled firm and any contemplated use of foreign national employees on this effort. Responses should be sent to: ATTN: KEVIN COX, WL/FIKF Bldg 7, 2530 C St, Wright-Patterson AFB OH 45433-7607. Non-technical assistance may be secured by calling the above individual at 513-255-3427. An Ombudsman has been established for this acquisition. The only purpose of the Ombudsman is to receive and communicate serious concerns from potential offerors when an offeror prefers not to use established channels to communicate his concern during the proposal development phase of this acquisition. Potential offerors should use established channels to request information, pose questions, and voice concerns before resorting to use of the Ombudsman. Potential offerors are invited to contact ASC's Ombudsman, ASC/CY, Col Robert C. Helt, at 513-255-1427 with serious concerns only. Closing date for submission of responses is thirty (30) calendar days from the publication of this notice. Firms should reference FIK-96-04 in their responses. RFP release for this program is projected in NOVEMBER 1995. This program will not be republicized prior to solicitation. See Numbered Note(s): 25. (0263)
