The invention relates to a front edge anti-icing device (1). The front edge anti-icing device comprises a pipeline assembly (2) and a front edge skin (8) wrapping the peripheral face of the pipeline assembly. The pipeline assembly comprises an air supply pipe (3) fixed to the inner circumferential surface of the pipeline assembly and extending in the length direction of the pipeline assembly; the gas distribution pipe (4) is positioned at the gas inlet end and is communicated with the gas supply pipe at the gas inlet end; the hot air channel (5) is arranged in the length direction of the pipeline assembly, the hot air channel is composed of a plurality of hot air pipelines (51), and the air inlet end of the air distributing pipe is communicated with the first end of the hot air channel; the gas collecting pipe (6) is positioned at the exhaust end and is communicated with the second end of the hot gas channel at the exhaust end; and the exhaust pipe is communicated with the gas collecting pipe at the exhaust end. The front edge anti-icing device not only can solve the problem that a front edge composite material structure is easy to lose efficacy, but also can improve the utilization efficiency of anti-icing hot gas.

    本发明涉及一种前缘防冰装置(1),包括管路组件(2)以及包覆在管路组件的外周面上的前缘蒙皮(8)。管路组件包括:固定到管路组件的内周面且沿管路组件的长度方向延伸的供气管(3);位于进气端的分气管(4),分气管在进气端与供气管连通;布置在管路组件的长度方向的热气道(5),热气道由多条热气管路(51)构成,分气管在进气端与热气道的第一端连通;位于排气端的集气管(6),集气管在排气端与热气道的第二端连通;以及排气管(7),排气管在排气端与集气管连通。前缘防冰装置不仅能够解决前缘复材结构易于失效的问题,而且还可以提高防冰热气体的利用效率。
