摘要
针对脉冲控制的迫弹的末段弹道修正问题,建立了基于周向脉冲控制的弹道模型。在确定脉冲发动机参数条件下,对不同起控距离下脉冲发动机控制修正的弹道进行仿真计算。得到了脉冲发动机对射程、偏流各向修正能力大小,其中对射程X方向的修正作用大于对偏流Z方向的修正作用;并且对射程X正向的修正作用强于对射程X负向的修正作用。对偏流方向的修正作用基本相同。研究结果对脉冲发动机的点火起控点选择以及脉冲发动机的个数选择都有一定参考价值。
In view of the problem of correction of the end of ballistic trajectory of mortar controlled by impulse en- gine, a ballistic trajectory model based on impulse engine control is built and simulated the trajectory controlled by im- pulse engine, fired at different distance from the target, under the certain impulse engine parameters. By simulation the impulse engine＇s correction capability was obtained. And the simulation result shows that the correction effect to the X axis direction is greater than to the Z axis direction, and that the correction to the X axis positive direction is greater than to the X axis negative direction and the correction to the two directions of Z axis direction is the same. So the research is important to the selection of the fire time and number of the impulse engine and serves as theory reference.
