The invention belongs to an air suction type combined cycle engine in the field of aviation hyperpower, and particularly relates to a composite anti-icing structure for a jet flow precooling device. Comprising an air supply structure and a heat transfer structure; the air supply structure is provided with an air supply channel, the heat transfer structure is provided with an outer side wall and an inner side wall, the inner side wall forms an inner side heat transfer channel extending from the top of the heat transfer structure to the root, and an outer side heat transfer channel extending from the top of the heat transfer structure to the root is formed between the outer side wall and the inner side wall; the inner side wall is provided with inner side through holes communicating with the inner side heat transfer channel and the outer side heat transfer channel, the outer side wall is provided with outer side through holes communicating with the outer side heat transfer channel and the outside, and the inner side heat transfer channel and the outer side heat transfer channel both communicate with the air supply channel. And meanwhile, due to the effect that the air film seam blows off overflow water drops, icing can be reduced in the area without hot air protection.
本申请属于航空高超动力领域的吸气式组合循环发动机,特别涉及一种用于射流预冷装置的复合防冰结构;包括供气结构与传热结构;供气结构,具有供气通道,传热结构具有外侧壁与内侧壁,内侧壁形成由传热结构顶部延伸至根部的内侧传热通道,外侧壁与内侧壁之间形成由传热结构顶部延伸至根部的外侧传热通道,内侧壁具有连通内侧传热通道与外侧传热通道的内侧通孔,外侧壁具有连通外侧传热通道与外界的外侧通孔,内侧传热通道与外侧传热通道均连通所述供气通道,本申请可以充分利用热气能量,合理调整能量分配,保证水撞击区域均能被防冰保护覆盖,同时由于气膜缝吹除溢流水滴的作用,可以在无热气防护区域减少结冰。
