面向起飞质量的小型飞航导弹参数优化方法

A parameter optimization method of small winged missile rienting to take-off mass

针对起飞质量对小型导弹总体参数设计的制约问题,以最小起飞质量为目标函数,应用复合形法,对小型飞航导弹纵向平面运动的方案弹道进行了总体参数优化设计研究。研究中考虑了法向过载、射程、最大速度、末速度、巡航高度和导弹离轨速度等因素。仿真结果表明:优化之后,导弹在飞行过程中的各特性参数满足总体指标要求的同时,实现了导弹起飞质量最小的目标。

In order to solve the restriction of the take-off mass to the overall parameter design of the small winged missile, this paper takes the minimum take-off mass as the object function , employs complex optimization to opti-mize the overall parameters of the small winged missile＆#39;s project trajectory in the vertical planar movement .The fol-lowing factors have been researched：the normal overload, range, the maximum and the terminal velocity , and the cruising altitude and off-track velocity .Simulation results show that the characteristic parameters during the flight can meet the overall indicators and achieve the minimum take-off mass after the optimization .
