Apparatus for the Measurement of Air Blast Pressures by Means of Piezoelectric Gauges

Abstract

Description and requirements are given of an apparatus used for measuring, by means of a piezoelectric gage, peak pressure and positive impulse in air blast from high explosives. Technique of measuring shock-wave velocity, from which peak pressure may be calculated, is described. Application of equation which relates pressure to velocity is discussed. Reproductions of typical oscillograms obtained with this apparatus are presented.
