某制导侵彻航弹飞行弹道研究

根据某制导侵彻航弹射程远、弹着角大的要求,提出该航弹的总设计指标,设计和优化了飞行方案.初始投弹段设计了俯仰角稳定回路,给出了频率特性曲线,中间段沿方案弹道飞行,根据模型风洞吹风试验数据设计和优化弹道,弹道末段采用改进型比例导引律并提出修正限制终点落角.数值仿真表明该飞行方案满足侵彻航弹对射程和末段着靶姿态的指标要求.

Research on Trajectory of Guided Penetrating Bomb

The design indexes of the bomb are presented based on the guided penetrating bomb's wide range and large terminal angle's request,the flight scheme is introduced and optimized.At the initial bomb-dropping stage the stabilized loop of the pitching angle is designed and the frequency characteristic curve is presented.In midcourse flight the scheme trajectory is tracked by the bomb.Ballistic trajectory is designed and optimized based on the aerodynamics parameters from model bomb's wind tunnel test.At the end ...
