- Description
- NASA/LaRC has a requirement to conduct a wind tunnel test in a Polysonic Wind Tunnel. The Ares I project is preparing an aerodynamic database that characterizes the 1st stage element of the vehicle during reentry where the aerodynamic effects are important for parachute deployment. This speed regime begins at separation, approximately Mach 6, and continues through splashdown. The aerodynamic database will be used to determine the Ares I 1st stage performance, stability & control effectiveness and structural stability. An assessment of the Design Analysis Cycle (DAC) 2 Ares configuration is to be made at the mid-cycle review in September 2007. To support this assessment, the aerodynamic database must be completed, reviewed, and delivered by August 2007. NASA/LaRC intends to purchase the services from Boeing, Inc. who is the only known responsible source. To support the assessment of the Ares DAC 2 1st stage element, the data to develop the aerodynamic database is required over the ascent Mach range. A wind tunnel model has been built to test at NASA MSFC?s Aerodynamic Research Facility, for the Mach range 0.5 ? 4.96. Due to the size of the tunnel, the effect of the shock reflection from the walls is a concern. A larger facility with a similar Mach range capability is needed to test the existing model and thus reduce or eliminate the reflection of the shock off the walls. The primary Mach range of concern is between 0.5 and 1.46. The Boeing Polysonic wind tunnel test covers the Mach range 0.4 ? 1.6 providing data for the reentry phase for Ares I 1st stage flight. This facility allows the use of the existing model and sting hardware. There are no NASA facilities available with this Mach range and size. The Boeing Polysonic tunnel is the only known blow-down facility with the specific Mach number range, Reynolds number, and size to satisfy the wind tunnel testing requirement. Also, to eliminate tunnel to tunnel and database to database comparisons, similar facilities need to be utilized. This eliminates some uncertainty in the aerodynamic database, thus reducing risk to the program. The authority for this action is the test program for commercial items (section 4202 of the Clinger-Cohen Act of 1996), and 10 USC 2304(c)(1). The Government intends to acquire a commercial item using FAR Part 12 and Part 13.5, Test Program for Certain Commercial Items. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on May 24, 2007. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition 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.
