Velocity Measurements in Aerodynamic Wind Tunnel (1T) Using a Laser Doppler Velocimeter

Abstract

The report describes the application of a laser Doppler velocimeter (LDV) in a transonic wind tunnel. The LDV, an in-house-developed instrument, measured two velocity components using the dual scatter principle. The flow was not seeded for this test, and the output data was processed by a special data processor developed at AEDC. The velocity data and flow angularity are presented for five Mach numbers together with the velocities obtained using conventional wind-tunnel instrumentation.
