Laser Doppler Velocimetry (LDV) Compatibility & Optical Access Support

The contract requires ensuring wind tunnel supports are fully compatible with Laser Doppler Velocimetry (LDV) systems by providing optimal optical access, light transmission, and precise beam alignment. This involves engineering and integrating structural components within the wind tunnel environment to maintain unobstructed line-of-sight for LDV laser beams, maximizing measurement accuracy and data reliability during aerodynamic testing. The work must guarantee consistent optical performance under operational conditions, accounting for potential distortions, vibrations, or environmental factors within the test facility. The solicitation is issued as a subcontract under NAICS code 333318, focused on instrumentation for wind tunnel testing, with performance required at Redstone Arsenal, Alabama 35898. The Department of Defense through W6QK Acc-rsa is the issuing agency, and responses are due by May 18, 2026, at 5:00 PM. The effort demands technical expertise in optical mechanics, fluid dynamics instrumentation, and wind tunnel engineering to deliver a reliable LDV-ready configuration without compromising structural integrity or test flow characteristics.
