Abstract : In July of 1983 Air Force Systems Command (AFSC) approved construction of the Subsonic Aerodynamic Research Laboratory (SARL). The SARL is designed to provide a low turbulence flow (O.05%) for flow visualization and precision measurements. The test section walls are 80% optical quality plexiglass. The large viewing area lends the facility to flow measurement by laser velocimetry, a nonintrusive flow measurement technique. A computer system is available for force and pressure data. The octagonal test section is 7'w X 10'h making it possible to test large models at high angles-of-attack. The SARL is designed for efficient low cost operation. The flow conditioning section of the tunnel contains both screens and honeycomb material. The facility was designed to operate up to Mach 0.6. A natural frequency problem with the drive system presently limits top speed to Mach 0.5. The SARL construction project is somewhat unique, being an in-house effort not requiring an MCP. A significant cost savings was realized because several major components needed for the SARL, were available from other unused facilities. The fan was obtained from NASA langley Research Center. The 20,000 hp drive system was supplied by Wright- Patterson AFB. Subsonic Aerodynamic Research Laboratory, Wind Tunnel, Aerodynamic Test Capability.
