摘要
The purpose of this paper is to develop a station-keeping performance analysis model for stratospheric airship with thermal and wind effects.during its conceptual design and help provide insight into the control strategies analysis of stratospheric airship. Firstly, an extreme differential pressure estimation model for stratospheric airship was introduced. Secondly, a thermal analysis model to describe the heat transfer behavior of stratospheric airships was developed. The temperature and pressure variations about the upper envelop, lower envelop and internal helium during its station-keeping are obtained. Finally, the ways for airship pressure adjustment was analyzed and the corresponding control strategy to different scenario was discussed.
