Design and Calculation of Large-span Throwing Solid Rocket Engine

Dong Qinxing;Gu Wenbin;Lu Ming;Liu Jianqing;Hu Yafeng;Chen Xueping;College of Field Engineering,PLA University of Science and Technology;  
The charge and nozzle of solid rocket motor used to rocket throwing system are designed based on its features of low mass and short range. The charge parameters design of single grain and three grains are proposed,and the internal ballistic calculation of solid rocket motor are carried out by fourth-order Runge-Kutta method. The design of three grains is selected by contrast of impulse. The chamber pressure and thrust of the solid rocket motor are obtained by experiment. The results show that the numerical results are consistent with the experimental data,and the design of engine fulfill the technical requirements of rocket throwing system.
