Development of Airblast and Soil Strength Instrumentation.

Abstract : The development and testing of airblast and soil strength gauges are presented. The airblast sensors include an accelerometer instrumented drag sphere to measure dynamic pressure and bar gauge probes to measure static, stagnation and reflected pressures at levels to 10 to the 8th power Pa (1 kilobar). The soil strength gauge is a shock hardened dynamic cone penetrator. An analysis of a slug type heat flux sensor is given. (Author)
