Entry/Reentry Corridor Design for Human Deep Space Exploration

Entry/Reentry corridor of crew vehicles describes the permitted limits of flight path angle when a crew vehicle performs entry or reentry task. In order to avoid bearing large acceleration, heat flux and total heat, crew vehicles must satisfy the constraint of entry/reentry corridor. In this paper, entry/reentry corridor design methods are presented for human deep space exploration. The method utilizes the predictive-corrective guidance to verify the feasibility of entry/reentry corridor result and calculates the design margin by analysis of variance based on the concept of factor of safety. Finally, the effectiveness of the proposed method is validated via the example of manned moon-earth reentry. This work will provide technique reference for entry/reentry corridor design and system engineering design for human deep space exploration.
