| 摘 要： | 确定了影响发动机内弹道性能的独立随机变量。其中，发动机肉厚与燃面的关系是根据发动机的试车数据，按照无因次肉厚概念对实测压强-时间曲线反算而获得。根据固体发动机内弹道性能预示模型，采用Monte-Cardo法进行内弹道性能的模拟计算。通过对某发动机的内弹道性能仿真，说明该计算方法可行、数据可信。

| Abstract: | Some independent random variables of internal ballistic calculation for solid motor were established. Among them the relation of grain burning area versus web was obtained by analyzing the motor test results and inversely calculating from the p-t curve based the dimensionless web. According to the internal ballistic foreshowing models of solid rocket motors, the interior ballistic performances were simulated and computed by using Monte-Carlo method. The results show that the computation method is feasible and the data are confident. |
