Development of Microprocessor-Based Laser Velocimeter and Its Application to Measurement of Jet Exhausts and Flows over Missiles at High Angles of Attack

摘要

During the past three years, personnel have developed a unique three-component laser velocimeter for the in situ measurement of particle and/or gas velocities in flow fields produced behind bodies at high angles of attack and in jet exhaust plumes. This report describes the development of the laser velocimeter and its subsequent application of the measurement of the velocity distribution and vortex structure in free jets and in flows over missiles at high angles of attack.
