The Use of Piezo Gages in Closed Bomb Tests of Solid Propellants

摘要

A mathemtical circuit analysis of the closed bomb measuring circuit was performed. This analysis provides a means of calcuating and elimi-mating the error inherent in the measuring circuit.nAn oscilloscope method for calibrating pieges was developed and a mathematical circuit anaysis of its circuit perfrmed. This method provides an accurate way to calobrate the gage used and the analysis determines the error inherent in this system of cailbration
