| 摘 要： | 提出了一种旋转固体火箭发动机的内弹道计算方法。在推导出旋转条件下的燃面变化规律的基础上,采用龙格库塔法求解了内弹道计算基本方程,并编制了计算程序。旋转和不旋转情况下的计算结果对比表明,旋转使发动机内压强增高,工作时间缩短,拖尾段加长。最后还就实验研究方法和实验结果处理进行了探讨。

| Abstract: | A method of internal ballistic calculation for spinning solid rocket motor has been presented in this paper. On the basis of given burning area for spinning solid rocket motor, the internal ballistic calculation equations are solved by Runge-Kutta method and the calculation program is obtained. Computation shows that the spinning of SRM makes the pressure in combustion chamber high, action time short and the pressure descending stage long. Lastly the experimental method and data disposal are discussed. |
