某制导火箭弹采用发动机有控分离技术,分离点可以选择在主动段和被动段。为研究分离点位置对外弹道特性的影响,建立了分离点分别在主动段和被动段分离时的弹道模型,并分别对两种情况下的弹道进行了仿真,通过分析仿真结果得出主动段分离时射程、射高和最大速度都小于被动段分离,而射程范围覆盖范围大于被动段分离,这对确定该制导火箭弹的弹道模型和最终的分离位置方案提供了依据。

Controlling separation technology of engine is used on one guided rocket. The engine is casted off in power phase or free phase. Two trajectory models are built in order to study the effect of different position of separation to trajectory characteristic. The simulation is done by the two trajectory model. The result tells that range, height and max speed when the engine is casted off in power phase is less than that when the engine is casted off in free phase, but the range scope is bigger. The final trajectory model and separation position will determined on the basis of the result.
