The Design, Fabrication and Field Testing of a Gas Particle Velocity Sensor.

Abstract

The vortex shedding anemometer (VSA) was developed by Kaman Sciences Corporation (ca. 1967) for measuring transient gas particle velocity in the flow behind an air shock wave. The original VSA was calibrated up to Mach 1 where the minimum response time was on the order of 700 microseconds. A higher velocity model has been designed and tested up to Mach 2.2 with a response time approaching 100 microseconds. This new device was calibrated in the quasi-steady state flow field of a transonic wind tunnel and in the transient flow in a shock tube. Four devices were fielded on test event DIRECT COURSE at the 240 KPa (35 psi) predicted overpressure level. Unfortunately, no unambiguous velocity measurements were recorded on this test due to interchannel modulation cross talk in the multiplexed recording system.
