The embodiment of the invention provides a reentry vehicle air suction injection type thermal protection device and a control method thereof. The thermal protection device comprises a load cabin; the protection part is arranged at the front end of the load cabin, the front end of the protection part forms the head of the aircraft, the tail end of the protection part forms the shoulder of the aircraft, a head air suction hole is formed in the head, and a shoulder jet hole is formed in the shoulder; and the head air suction hole communicates with the shoulder jet flow hole through the guide assembly, and the head air suction hole is used for guiding incoming flow air sucked by the head air suction hole to the shoulder jet flow hole to be jetted out, so that thermal protection is formed on the shoulder. According to the embodiment of the invention, no extra working medium is needed, incoming air is absorbed by the head and guided to the shoulder for thermal protection of the shoulder of the aircraft, and meanwhile, the problem of head burning is solved.

    本申请实施例提供一种再入飞行器吸气引射式热防护装置及其控制方法。热防护装置包括:载荷舱;防护件,设置于载荷舱的前端,防护件前端构成飞行器的头部,防护件的尾端构成飞行器的肩部,其中,头部设置有头部吸气孔,肩部设置有肩部射流孔;引导组件,头部吸气孔通过引导组件与肩部射流孔连通,用于将头部吸气孔吸收的来流空气引导至肩部射流孔射出,以使肩部形成热防护。本申请实施例无需携带额外工质,依靠头部吸收来流空气并导引至肩部进行飞行器肩部的热防护,同时也解决头部烧灼问题。
