| 摘 要： | 为了解决基于模块化研制的运载火箭其飞行剖面载荷与承载能力不匹配而导致发射概率过低的问题，提出一种基于弹道风修、发动机节流、主动减载、横向动载荷精细化四项减载技术的飞行载荷联合优化控制技术。以箭体承载能力为约束，提高发射概率为目标，多种载荷控制技术联合为手段对运载火箭进行逆向设计，可以有效提高模块化研制火箭的发射概率。以长征八号运载火箭首飞为例，该技术成功将发射概率由研制初期的33%提高到83%。

| Abstract: | The launch probability of the modular launch vehicle is too low due to the mismatch between the flight load and the bearing capacity. To solve this problem, a joint optimization control method for lunch vehicle’s flight load based on ballistic wind correction, engine throttling, active deloading and refining of transverse dynamic load is proposed. With the constraint of vehicle body bearing capacity, this method joints multiple load control technologies to design a launch vehicle reversely for the purpose of improving launch probability.Taking the first flight of the Long March 8 launch vehicle as an example, this technology has successfully increased the launch probability from 33% in the initial stage of development to 83%. |
