摘要:

本文提出了侵蚀燃烧所产生的压力峰补偿增面燃烧段低压部分的构想,从而达到在实际上消除初始压力峰的目的.并且通过设计实例及其实验结果,说明了这一方法在工程实践中的具体应用及其有效性.

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.
