    针对某小型固体火箭发动机的内弹道进行数值仿真研究。绘制固体火箭发动机的物理模型，分析其结构特点，建立简化的基本方程组，运用matlab软件对一阶微分方程组进行数值求解，得到燃烧室压力随时间变化曲线。通过与试验曲线相比较，发现它们的变化规律相吻合，从而为火箭发动机的优化设计提供有价值的参考。

    Numerical simulation is researched for interior ballistic of a small solid rocket motor.The physical model of solid rocket motor is drawn.Its structure characteristics are analyzed and simplified fundamental equ-ations are established.First-order differential equations are solved numerically by using matlab software.The time curve of combustion chamber pressure is acquired.By comparing with the experimental curve,it is found that their variation rules are consistent.So the valuable references for optimal design of rocket engine are provi-ded.
