The invention provides a propelling support and a stratospheric airship. The propelling support comprises a force bearing support, a transition frame is installed on the top of the force bearing support, and the force bearing support and the transition frame are composed of three-dimensional multidirectional woven carbon fiber tubes. According to the propelling bracket provided by the invention, the transition frame and the bearing support are formed by the three-dimensional multidirectional woven carbon fiber tubes, so that the problem that the large-scale power propelling bracket for the stratospheric airship is heavy is solved, the self weight of the propelling bracket is reduced, the load of the stratospheric airship is reduced, and the power propelling efficiency of the stratospheric airship is improved. Meanwhile, the fatigue response during coupling of the propelling support and the stratospheric airship body is reduced, and the problem of stress concentration at the coupling position is effectively solved.
本发明提供一种推进支架及一种平流层飞艇。本发明提供的推进支架包括:承力支架,所述承力支架的顶部安装有过渡架,所述承力支架和所述过渡架采用三维多向编织的碳纤维管构成。本发明提供的推进支架,通过采用三维多向编织的碳纤维管构成过渡架和承力支架,解决了平流层飞艇大尺度动力推进支架重量较重的问题,减轻了推进支架的自重,降低了平流层飞艇的负荷,提高了平流层飞艇的动力推进效率。同时,降低了推进支架与平流层飞艇艇体耦合时的疲劳响应,耦合处应力集中的问题得到了有效改善。
