The present invention relates to a flute-shaped pipe for aircraft deicing. The flute-shaped pipe comprises a flute-shaped pipe body having a hollow interior cavity, a first end, a second end, and a plurality of holes disposed in a circumferential surface of the flute-shaped pipe body, wherein the first end is closed and the second end is in fluid communication to a hot fluidsource; and a plurality of nozzles, wherein each nozzle of the plurality of nozzles is attached to the plurality of holes in the flute-shaped pipe body and is in fluid communication with the hollow inner cavity. The heat exchange efficiency of the device can be improved through the flute-shaped pipe. Under the same anti-icing power requirement, compared with a traditional flute-shaped pipe, the provided flute-shaped pipe can adopt lower air entraining temperature, thermal protection on slats and leading edge materials is better, and the possibility of using composite materials with lower heat-resistant temperature is also provided.

    本发明涉及一种用于飞行器除冰的笛形管,该笛形管包括:笛形管本体,笛形管本体具有中空的内部腔体、第一端、第二端以及设置在笛形管本体的周向表面上的多个孔,其中,第一端闭合,而第二端流体连通到热流体源;多个喷管,多个喷管中的每个喷管分别附连到笛形管本体上的多个孔并与中空的内部腔体流体连通。通过该笛形管能增加装置换热效率。在同等防冰功率需求下,本发明较传统笛形管可采用更低的引气温度,对缝翼及前缘材料的热保护会更好,也提供了使用耐热温度更低的复合材料的可能。
