Abstract
The development of a piezoelectric gage for the measurement of powder pressures in guns is reviewed. A gage is obtained having a high natural frequency, insensitivity to shock, and accuracy. Details concerning the construction of the gage, the recording apparatus, and the method of calibration are given. Records are reproduced showing pressure waves in a gun and a closed chamber. Such records have been of value in the improvement of the design of powder charges and the determination of interior ballistic data.
