Preliminary Measurements in a Supersonic Gun Simulator
Abstract
The development of a high-speed gun simulator (Mark III) has been completed and it has been shown to produce transonic projectile velocities in excess of 400 m/s with initial pressures up to 60 bar. Preliminary measurements of pressure and gas velocity have been obtained using the instrumentation of the subsonic Mark II rig and were limited to initial pressures of around 1 bar with consequent gas velocities less than 50 m/s at a location close to the initial chamber. In order to extend the range of measurements to supersonic gas and projectile velocities in excess of 400 m/s new instrumentation have been developed to determine time-dependent pressure, gas velocity, and heat flux information simultaneously and relay them to a computer within 10 us in order to resolve the characteristics during the short cycle of typically 7 micro.
