Pressure Gauge with One-Tenth Microsecond Risetime for Shock Reflection Studies

Abstract

A pressure gauge having a risetime of 0.1 μsec, no overshoot, a dwell time of 5 μsec, and capable of sensing a pressure jump of 10 mm Hg is described. Pressure‐time traces obtained with the gauge on the end wall of the 17‐in.‐diam low pressure shock tube at the Graduate Aeronautical Laboratories, California Institute of Technology, are presented showing details of the pressure profiles on the end wall for reflecting shock waves.
