ABSTRACT:
A device of monitoring propellant burning within, and erosion of, a rocket motor case by measuring the voltage-induced capacity of gages on the external surface of the case is described. A burning propellant generates a conducting gas within the burn front inside the motor. The resultant voltage is caused by an injected voltage pulse on a metal igniter ring in contact with or capacitatively coupled to the gas.
