Repetitively Pulsed Hypersonic Test Facility for Advanced Laser Diagnostic Development Conference Paper uri icon

abstract

  • A repetitively pulsed hypersonic flow apparatus has been constructed and characterized. This apparatus was designed to enable advanced laser diagnostic development. The underlying principle is to synchronize the intermittent tunnel operation with the laser pulses to achieve effectively continuous operation. We demonstrated repetitively pulsed (2-20 ms pulse length) uniform supersonic flow at Mach 4.6 and hypersonic flow at Mach 6.2 for extended operation. The nozzle flows were characterized using fast response pressure sensors and NO PLIF imaging for two-dimensional temperature and velocity measurements. The pulse-to-pulse impact pressure repeatability was within 1.0% corresponding to exit flow velocity and temperature fluctuations of 0.7% and 1.0%, respectively. The apparatus can operate over a unit Reynolds number range of 6.010 4 m -1 to 3.010 6 m -1 . Copyright 2012 by the American Institute of Aeronautics and Astronautics, Inc.
