Chapman理论在再入走廊计算中的应用

再入走廊给出了飞行器满足任务要求、并安全返回地球的再入飞行范围，它是再入轨道优化、再入方案设计、再入飞行任务规划等的重要部分。文章通过再入动力学建模，引入Chapman假设，进行了航天器从外层空间返回的再入走廊的研究，分析了影响再入走廊边界的重要因素，并以航天飞机为例计算了再入走廊，验证了该分析方法的正确性。

Computing Reentry Corridor Using Chapman Theories

Reentry corridor defines an reentry zone where the vehicle can fulfill flying mission and reenter the Earth safely, which is an important part of reentry trajectory optimization, reentry design and fly mission. In this paper, Chapman assumptions and dynamics model of reentry are introduced, and reentry corridor of vehicle from space is studied. The important points effecting reentry corridor boundary are introduced, the result proves the effectiveness of the analysis.
