Non-intrusive, Very-High-Speed (100 kHz), Time-Resolved Velocity and Temperature (Rotational and Vibrational) Measurements in Large-Scale Hypersonic Wind Tunnels

The Department of Defense, specifically the United States Air Force, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program for the development of a non-intrusive, very-high-speed instrument capable of measuring velocity and temperature in large-scale hypersonic wind tunnels. The objective is to create a system that can perform time-resolved measurements at rates up to 100 kHz, which is essential for accurately characterizing turbulence and flow physics in hypersonic environments, particularly in the AEDC Hypervelocity Tunnel 9. This initiative is critical for advancing the understanding of hypersonic flight vehicle dynamics and improving computational fluid dynamics (CFD) models. The solicitation is currently in the pre-release phase, with an open date of January 8, 2025, and a close date of February 5, 2025. Interested parties can find more information and submit proposals through the official SBIR website.
