The embodiment of the invention provides a multi-mode combined adjustable thermal protection device and method for a reentry vehicle. The thermal protection device comprises a load cabin, the head of which is provided with a windward cavity recessed inwards; the head protection part is arranged at the head of the load cabin and is provided with a head opening communicated with the windward concave cavity; the moving part is movably arranged in the windward concave cavity and is provided with a first air spraying hole; the jet device is arranged in the load cabin and is communicated with the first air injection hole; and jet gas jetted by the jet device can push the moving part to move towards the head of the load cabin, so that the first gas jet hole is exposed out of the opening of the head. According to the embodiment of the invention, switching of multiple thermal protection modes can be realized, and compared with a single mode in a traditional mode, the thermal protection effect is more efficient and reliable.
本申请实施例提供一种再入飞行器多模式组合可调节热防护装置及防护方法。热防护装置包括:载荷舱,头部设置有向内凹陷的迎风凹腔;头部防护件,设置于载荷舱头部,具有与迎风凹腔相通的头部开口;移动部件,可活动地设置于迎风凹腔内,设置有第一喷气孔;射流装置,设置于载荷舱,与第一喷气孔连通;其中,射流装置喷射的射流气体能够推动移动部件向载荷舱头部方向移动,使第一喷气孔暴露于头部开口外。本申请实施例,能够实现多种热防护模式切换,相较于传统方式单一模式,热防护效果更高效可靠。
