A -- RESEARCH PROPOSAL ENTITLED "AERODYNAMIC INVESTIGATIONS OF THE INBOARD-WING CONCEPT" SOL 1-168-BAC.0751 DUE 060999 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-BAC.0751. E-MAIL: Kimberly D. Duncan, k.d.duncan@larc.nasa.gov. NASA/LaRC plans to issue a Request for Quotation (RFQ) for a Research proposal entitled "Aerodynamic Investigations for the Inboard-Wing Concept" which shall involve 1) The development of a computational simulation technique applicable to the inboard wing airplane concept; 2) The design, construction, and wind-tunnel testing of inboard-wing airplane models; and 3) The documentation of the experimental and computational results and the correlation of the results to verify the validity of the methods. The purpose is to do a computational simulation of the inboard-wing concept and to conduct wind-tunnel force tests of a new, larger model at higher Reynold's numbers in order to support the computational work. The wind-tunnel investigation shall provide for a visual study of the surface flow on the model and the wake characteristics aft of the model. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/LaRC intends to purchase the items from the Virginia Polytechnic Institute and State University (VPI&SU), Aerospace and Ocean Engineering Department, Blacksburg, VA, unique services available from only one source. This procurement is the result of an unsolicited proposal that demonstrates a unique and innovative concept and demonstrates a unique capability to provide this particular research service not otherwise available to the Government and does not resemble the substance of a pending competitive acquisition. VPI&SU will use a unique coordination of resources available consisting of: 1) The computation of the aerodynamics of this unusual concept through the use of a special vortex panel method, 2) The necessary correlation of the computational results with experimental results would be done through wind tunnel testing of high-fidelity models of the concept. VPI&SU has a wind tunnel which is ideally suited to this study. The size and the speed of the tunnel will permit testing at a desired Reynolds number of about 2.5 million per foot, and the test section length is such that the desired downstream wake visualization can be accommodated. This unique combination of skill and facilities is not otherwise available to the Government. 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 submitan offer which shall be considered by the agency. An Ombudsman has been appointed.
