脉冲火箭弹模型仿真

通过对脉冲修正力的研究,建立了使用末段脉冲修正的制导火箭弹的空间质心运动方程和旋转运动方程,并通过计算机仿真证明了此模型的可行性,得出以下规律:(1)修正距离随着修正力大小的增加而不断增加,当力的大小为5 000 N时修正距离最大;(2)修正距离随着修正力作用点与质心的距离的增加而增加,当距离为0.5 m时修正距离最大。

A Simulation of the Theory of Rockets Using Impulse Correction

Based on the study of impulse correction force,this paper establishes both the motion equation of center of mass and the rotation equation of the guided rockets using impulse correction,and demonstrates the feasibility of the model through computer simulation.(1) The correction distance increases as the force increases,and the correction distance is the maximum when the force is 5 000 N.(2) The correction distance increases as the distance between the force point and the center of mass increases,and the correction distance is the maximum when the distance between them is 0.5m.
