摘　　要：研究火箭弹发动机内弹道性能,主要是对燃烧室内压强随时间的变化规律进行研究。一般采用实验法可以获得直观可靠的数据,由于在燃烧室中的压强很大,对实验的设备要求较苛刻,需要具备一定的条件才能进行实验。根据零维内弹道数学模型,应用Simulink仿真模型对某型固体火箭弹发动机内弹道工作过程进行数值仿真,画出燃烧室内压强曲线,进一步分析并得出影响发动机内弹道性能的因素。The interior ballistics performance of rocket engine is studied, and mainly carry on research with the changing law of pressure in the blast chamber while time changes, at the same time experimentation can achieve the intuitionistic and credible data, as the pressure in the blast chamber is extremely high, which requires the apparatus of equipment very harsh, also need to possess certain condition to carrying on the experiment. According to mathematic model of zero-dimensional interior ballistics,the mode of Simulink is applied to take numerical simulating of the interior ballistics working process of a certain rocket projectile. The pressure-time curve of the blast chamber is drawn, further the factors influencing the interior ballistics performance is analyzed and obtained.
