变射面弹道横向转弯飞行程序的设计与优化

Design and Optimization of Lateral Turning Flight Program on Changeable Launching Plane Trajectory

为有效提高导弹的突防能力和禁避飞区规避能力,实现小射程能量的有效利用,提出一种变射面横向机动弹道,通过初始离面角使弹道一级偏离传统射面,后面级再变换射面以命中目标。针对该机动弹道变换射面的横向转弯段,建立了横向转弯飞行程序仿真模型,为确定最优初始离面角和转弯飞行程序模型参数,采用混合优化算法对其进行了优化。仿真结果表明,模型能够满足弹道横向机动变换射面转弯要求,优化算法能够实时、快速求得最优初始离面角和最优飞行程序,满足射前诸元准备时间要求,实际应用性强。

In order to improve the capability of avoiding no-fly zone and penetration,a changeable-launching-plane transversely-maneuvering-trajectory was proposed to increase the fuel efficiency of short-range.The first-stage of missile was deviated from traditional launching plane through the initial out-of-plane angle,and then the launching plane was changed in the following stage to hit the target.The flight program simulation model was designed to complete the lateral turn and optimization through the designed hybrid optimization algorithm.The simulation results show that the proposed lateral turning flight program model can meet the requirements of transversely maneuvering trajectory for changing the launching plane.The initial out-of-plane angle and flight program can be obtained in real time through the optimization algorithm.
