Summary
The U.S. Army Contracting Command-Redstone is conducting market research to identify potential sources that can provide a brand-name closed-circuit wind tunnel for use by USATA Engineers and Technicians with a Laser Doppler Velocimetry (LDV) system for air velocity measurement [1][2]. The required tunnel must accommodate seed particles via a Swagelok fitting, achieve a maximum operating speed of approximately 50 m/s, feature a 60.96 cm x 60.96 cm test section, and include a centrifugal fan with a variable-frequency drive controllable via National Instruments LabVIEW [2]. The equipment will be delivered to the Army Primary Standards Laboratory (APSL) at Building 5435 Fowler Road, Redstone Arsenal, AL 35898 under solicitation number PANRSA-26-P-0000-037658 [1][2].
