新一代大型运载火箭长征五号控制技术

Control Technology of New Generation Large Launch Vehicle Long March 5

新一代大型运载火箭长征五号的控制精度、控制品质、系统架构、飞行可靠性已达到国际先进水平。系统介绍了长征五号控制系统的关键技术,即超20吨级有效载荷的大推力直接入轨高精度制导控制、覆盖超地球第二宇宙速度地火转移轨道的全域强适应制导控制、千吨级运载火箭助推和芯级异类发动机联合摇摆控制等多项技术。其成果填补了中国空白、大幅提升了中国自主进入空间的能力。

The control accuracy,performance,system architecture,and flight reliability of the new generation large launch vehicle Long March 5(LM-5),has reached the international advanced level.The key technologies of LM-5 control system are systemically introduced,as known as the high thrust accurate guidance control sending over 20 tons payload directly into orbit,the interplanetary strong adaptive guidance control covering the Earth-Mars transfer orbit with second cosmic velocity,the combined swing control of booster and core stage multiple heterogeneous engines for thousand-ton launch vehicle et al.These achievements have filled the domestic gap and greatly enhanced China’s ability to enter space independently.
