Abstract: When solid propellant burns in rocket motors, the unwanted corrosive pressure peak frequently and generally appears. In this paper, a pressure-compensating design method with which the peak can be eliminated is developed. The essential thought about this method is to design the grain for progressive burning to compensate the pressure peak in the initial burning stage.A design example and its test results prove out the applicability of this method.
