About this opportunity
The US Air Force Academy seeks design, fabrication, and delivery of a six-component force balance system for the Mach 6 Ludwieg Tube (M6LT) hypersonic wind tunnel facility, with proposals due September 21, 2026. The procurement underwent set-aside and evaluation methodology changes: it was initially a 100% small business competitive set-aside with questions due by July 28, then amended to full and open on September 16, with evaluation shifted to a three-lowest-price phased methodology (price first, then technical and past performance for lowest-priced quotes only). Funds are not presently available; no award will be made until funding is secured.
Place of performance is the Air Force Academy, Colorado. The balance must have a one-inch outside diameter, acquire steady-state force and moment data within 80 milliseconds of nominally steady run time, and integrate with existing National Instruments LabView software and cDAQ chassis (NI-9239, NI-9237, or equivalent cards) with no additional purchases required upon delivery. The contractor must provide a fully functional turn-key system including sting, calibration models, checkout testing, and detailed training. Critical design parameters—axial/normal/side force ranges (Fx, Fy, Fz), moment ranges (Mx, My, Mz), maximum startup/transient loads, accuracy and repeatability specifications, and calibration standards—are to be established collaboratively during the design phase. Minimum confirmed requirements include 10 kHz bandwidth, 60–120 degrees Fahrenheit operating temperature, 1–1500 mbar pressure range, and minimum 2x safety factor. The contractor must conduct pre-design tunnel testing using existing balances to characterize startup loads on canonical geometries before finalizing design. Test models range from slender cones to blunt bodies, typically under 10 pounds.
The contract is firm fixed price with delivery by August 31, 2027, and will be awarded to HQ USAFA Division of Engineering. NAICS code 334519 (Other Measuring and Controlling Device Manufacturing); PSC 6670 (Scales and Balances). USAFA's preference is domestic end products per Buy American Statute (41 USC Chapter 83); foreign offers will be evaluated per R-DFARS 225.502. All completed proposals must include the Buy American—Balance of Payments Program Certificate (R-DFARS 252.225-7000). Payment is on completion of contract line items; progress payments are not permitted.
