摘　　要：针对临近空间滑翔飞行器的变形需求,提出一种具有较高环境适应性的伸缩式可变形滑翔飞行器(MGV),建立了含有冗余控制变量的MGV轨迹优化模型,利用伪谱法量化分析了MGV在射程覆盖能力、规避绕飞能力和末段打击能力三方面的性能收益,得到了飞行过程中的最优控制律和最优变形律,可指导制定变形策略和设计变形控制系统,为滑翔飞行器的后续发展和变形飞行器的相关研究提供参考。Based on the morphing requirements of the glide vehicles,a morphing glide vehicle（ MGV） with high environmental adaptability is proposed. The trajectory optimization model of an MGV with redundant control variables is established. The pseudospectral method is used to the trajectory optimization,and the maneuverability and gliding ability of the MGV are quantitatively analyzed. The simulation results show that in some typical combat modes,the MGV ＇s performance can be effectively enhanced. At the same time,the optimization results can guide the morphing strategy and control system design. This article provides a reference for the scheme design and mission planning of the morphing vehicles.
