Instrumentation for Measuring Pressure Waves in Guns

Abstract

The continuous measurement of the pressure difference between the breech and forward ends of a cannon chamber is used by the charge designer to make an evaluation of the ignition process and to determine the existence of pressure waves. The technique of making this measurement involves the analog differencing waves. The technique of making this measurement involves the analog differencing of two optimally located transducers with a recording system that is properly adjusted, calibrated, and scaled. The resulting differential pressure versus time relationship reveals wave structure that may not be obvious by visual inspection of the two original pressure-time curves.
