VELOCITY MEASUREMENTS IN THE AEDC LOW SPEED WIND TUNNEL (V/STOL) USING A LASER DOPPLER VELOCIMETER

Abstract

An in-house developed laser Doppler velocimeter (LDV) was used to make velocity measurements in a low speed wind tunnel. The installation and instrumentation are discussed, and velocity profiles obtained with the LDV are compared with those obtained using conventional techniques. A discussion on the factors which affect the accuracy of the LDV and improvements that would be desirable are also included.
