基于姿态火箭的弹射座椅轨迹控制技术研究

摘要

This paper presents a general concept of ejection seat capable of roll control by the normal attitude rocket . Through simulation computation ,the effects of attitude rocket impulse on man‐seat trajectory have been studied at varied e‐jection speeds ,roll angles ,and delayed firing of rocket motor .Results have shown that normal attitude rocked ,coupled by delayed firing of rocket motor ,is significant to seat performances during adverse ejection .%对基于常规姿态火箭进行横滚姿态控制的弹射座椅基本方案进行了阐述，通过仿真计算对不同弹射速度、横滚角度、火箭包延迟点火时间下姿态火箭冲量对人椅相对轨迹高度的影响进行了研究。研究结果表明常规姿态火箭配合火箭包延时点火对提高弹射座椅在不利姿态下弹射时的性能具有显著的效果。
