【摘要】 为了快速预估冲压炮弹冲压发动机在设计点时的性能参数,根据冲压炮弹冲压发动机工作原理,利用一维气体定常流理论建立了冲压发动机内弹道的物理、数学模型。利用C++语言开发了发动机内弹道计算程序进行了典型算例的计算。通过将计算结果与实验数据比较,表明该方法在对固体冲压发动机内弹道计算上有一定的精度,能够满足工程设计阶段的要求。更多还原

【Abstract】 In order to fast estimate the performance parameters of ducted solid rocket ramjet on the design point.A method of internal ballistic calculation in ramjet extended range projectiles was established,and established physical and mathematical model of ducted solid rocket ramjet,according to the theory of gas one-dimension steady flow.Using C++language has developed a ballistic computer program within ducted solid rocket ramjet.The calculation results,by contrast with test dates,show that the method of interior ballistic calculation of solid rocket ramjet have a certain accuracy to meet the requirements of the ramjet design phase.更多还原
