Exterior Ballistic Theory and Numerical Simulation for a Ramjet Propelled Projectile

简述了冲压增程炮弹增程原理,建立了进气道、发动机一体化外弹道计算模型,通过数值仿真得到了155 mm增程弹弹道曲线。通过对仿真结果进行分析,得到了射程随部分设计变量变化的关系曲线,为增程弹总体优化设计奠定了理论基础。

The range extended theory of a ramjet propelled projectile was simply presented, and the exterior ballistic trajectory prediction model was established, which incorporates the inlet with the ramjet. Based on the model, the trajectory of a 155 mm projectile was numerically simulated. Through the analysis of the results, the relation curves between the range of the projectile and some design variables were attained. The conclusions are available for the optimum design of a ramjet propelled projectile.
