External Heat Flux on Manned Transport Spacecraft with Multiple Modes and Attitudes

doi:10.3780//j.issn.1000-758X.2011.01.004

Abstract

Abstract: External heat flux analysis is not only the foundation of thermal control design and thermal analysis, but also the significant thermal boundary condition for ground thermal test. Based on theoretical analysis, a spacecraft external heat flux model was developed and the heat flux was calculated in different flight modes and attitudes. In addition, the heat flux characteristics was obtained in the extreme case. The results show that heat flux increases with the augmentation of percent time in sunlight when the spacecraft is in three-axis stabilized attitude, but decreases abruptly when it turns into the yaw maneuver, and then the heat flux will decrease with the augmentation of percent time in sunlight reversely.

Key words: External heat flux, Flight model, Flight attitude, Rendezvous and docking, Manned spacecraft
