Top Wind Tunnels

The U.S. Army Contracting Command-Redstone, supporting the U.S. Army Test, Measurement, and Diagnostic Equipment Activity, is conducting market research through a Request for Information to identify potential sources capable of providing two wind tunnels for use in OCONUS support of hot-wire anemometer calibration. This RFI is purely for planning purposes and does not constitute a solicitation, guarantee of future procurement, or obligation by the government. Respondents must provide company details including full legal name, business size, socio-economic status, point of contact information, CAGE code, and Unique Entity Identifier, with all submissions due by June 25, 2026, at 2:00 PM Eastern Time via email to the designated contracting officer and specialist. The wind tunnels must generate air speeds from 1.5 to 50 meters per second with a measurement uncertainty of no more than 0.75 percent, maintain turbulence intensity at or below 1 percent, and operate on a 220V 16A single-phase power supply with a maximum noise level of 90 dB at peak speed. The test chamber must measure at least 4 by 4 inches and no more than 12 by 12 inches in cross section, and the entire unit must fit through a standard 32-inch door with overall dimensions not exceeding 10 by 3 by 6 feet. If a closed-circuit design is not feasible within budget, an open-circuit design is acceptable, and units weighing more than 45 kilograms must be mounted on a frame with casters. The equipment must be delivered to the TMDE Support Centers in Kaiserslautern, Germany, and Camp Carroll, South Korea, and include calibration software that requires no annual subscription or online connectivity; if the software license is not transferable, a dedicated computer must be provided. The software must be capable of reporting both standard and actual wind speed, correcting for pressure and temperature variations, and exporting test data. The NAICS code associated with this requirement is 334519, and no set aside designation has been determined. Responses are voluntary, and the government will not compensate respondents for any cost incurred. Any future solicitation will be posted on SAM.gov, and interested parties are advised to monitor the site for updates.
