摘　　要：药柱的几何形状、尺寸和燃烧面积直接决定着水下航行器动力系统的启动特性,也影响着推进剂供应管路的设计,所以对药柱的燃烧特性进行精确建模。在建立药环和2种药柱的燃烧模型的基础上,同时引用其它部件数学模型,建立动力系统启动过程的完整数学模型,并采用Mat-lab进行仿真实验计算,研究2种药柱对启动过程的影响。结果表明,改进后的实心药柱能够很好地改善水下航行器热动力系统启动过程。The starting characteristics of thermal power underwater vehicle system is determined by the geometry, size and burning area of the solid ignition grain, which has a direct effect on the liquid propellant pipeline design. It is of course necessary to establish the accurate burning models of solid ignition grain. Based on the burning models of two different solid ignition grains and powder ring, the starting process mathematic models of the power system were built. With the help of Matlab a series of imitating calculations were made for the effects of different grains on the starting process characteristics. The results show that end-burning grain will give better behavior to the starting process of the thermal power underwater vehicle system.
