The embodiment of the invention provides a reentry vehicle shoulder jet flow thermal protection device and a control method thereof. The protection device comprises a load cabin; the protection wings are arranged on the periphery of the load cabin in a surrounding manner; the protection wing comprises a plurality of unfolding rods, each unfolding rod comprises a rod body and a jet device arranged in the rod body, the front end of each rod body is movably connected with the load cabin, a jet hole is formed in the tail end of each rod body, an unfolding hole is formed in the side wall of each rod body, and the jet holes and the unfolding holes are communicated with the jet devices respectively. When jet gas jetted by the jet device is jetted out of the unfolding holes, the protection wings are switched from the folded state to the unfolded state; when jet flow gas jetted by the jet flow device is jetted out of the jet flow hole, the jet flow gas forms thermal protection on the tail end of the unfolding rod. According to the embodiment of the invention, the medium jet is carried in the internal space of the unfolding rod to unfold the aircraft and thermally protect the whole aircraft, so that the space utilization rate is improved, and the load carrying of the original aircraft is not influenced.

    本申请实施例提供一种再入飞行器肩部射流热防护装置及其控制方法。防护装置包括:载荷舱;以及防护翼,围绕设置在载荷舱的外周;防护翼包括多个展开杆,每个展开杆包括杆体和设置于杆体内的射流装置,杆体的前端与载荷舱活动连接,杆体的尾端设置有射流孔,杆体的侧壁设置有展开孔,射流孔和展开孔分别与射流装置连通,其中,射流装置喷射的射流气体从展开孔喷出时,使防护翼由收拢状态切换为所述展开状态;在射流装置喷射的射流气体从射流孔喷出时,射流气体对展开杆的尾端形成热防护。本申请实施例,利用了展开杆内部空间携带介质射流进行飞行器的展开以及整体飞行器的热防护,提高了空间利用率,不影响原来飞行器的载荷携带。
