摘　　要：低成本空间运输是实现人类对太空探索和开发的重要关键之一.利用气动力的变轨技术,在大气层的很多变轨任务中可以增加有效载荷质量.气动力辅助变轨(AOT)和最优控制理论,尽管早在20世纪60年代就已经开始研究,但是到现今仍然处于发展中.特别是由推力协同变轨所导致的奇异最优控制问题到目前尚没有完全解决.研究这些理论的目的是为了确立那些精确分析方法,以确定在给定约束条件下的最佳策略.从AOT轨道的精确控制需要和消除各种来源的误差影响看,至关重要的是制导方案的研究.(?)个历史的审视和对这个领域的最新研究都在本文里作出讨论,由此AOT飞行器的未来研发将为人类开辟通向宇宙之路.To lower cost in space transportation is one of the keys to the exploitation and exploration of space. Aeroassist technology, which uses aerodynamic forces, can offer a significant increase in payload mass delivery capability. The optimal aeroassisted orbital transfer (AOT) and optimal control are in the development. stage, although the related theories have been studied since the early 1960's. Up to now the singular optimal control problems in the thrust synergetic orbital transfer have not been completely solved. The goal of the theoretical development is to establish the accurate analysis methods for determining the best strategy with given constraints. Oi critical importance is the development of guidance schemes in view of the precision requirment of AOT trejectories and the need for coping with various sources of dispersion offects. A comprehensive historical review and some recent progress of these fields are presented in this paper, and the future development of AOT vehicles will opening a road to the space.
