子母弹抛撒参数优化与抛撒/盲区半径误差分析
|
摘要
以抛撒半径和抛撒盲区作为优化目标,以母弹抛撒时的高度、速度、当地弹道倾角、子弹最大抛撒速度和子弹最小抛撒速度等抛撒参数为优化变量,研究了子母弹抛撒参数优化设计方法。以该优化方法计算了一个算例,利用计算得到的偏导数进行了抛撒半径和盲区半径的误差分析。
Considering the deficiency of traditional calculation methods, a novel optimal calculation method of dispersion radius and blind-area radius is proposed. In the proposed method, some trajectory parameters such as dispersion height, velocity, flight path angle of missile, maximum and minimum ejecting velocities of bullets are adopted as the major input constraints. At last, the efficiency of the proposed method is verified by a simulation example, in which dispersion radius and blind-area radius errors are analyzed by utilizing the partial derivatives of the equations.
