The invention discloses an air inlet channel, and relates to the technical field of aircrafts, the air inlet channel comprises an air inlet channel body, the air inlet channel body is provided with an air inlet and an air outlet, the inner wall of the air outlet is provided with an overflow hole, the overflow hole is provided with an elastic cover plate, and the overflow hole is slidably connected with the elastic cover plate; and the elastic cover plate is used for automatically closing and opening the overflow hole. Compared with an air inlet channel provided with an overflow groove in the prior art, the air inlet channel can effectively avoid the problem that the aerodynamic performance and stability of the air inlet channel are reduced due to the fact that external air flows back into the air inlet channel through the overflow hole while the distortion of the outlet is reduced.

    本发明公开了一种进气道,涉及飞行器技术领域,包括:进气道本体,所述进气道本体具有进气口和出气口,所述出气口的内壁上设有溢流孔,所述溢流孔上设有弹性盖板,所述溢流孔和所述弹性盖板滑动连接,所述弹性盖板用于溢流孔的自动闭合和打开。相比于现有技术中开设有溢流槽的进气道,本申请中的进气道,在减小出口畸变的同时,可以有效的避免外部气体通过溢流孔回流进入进气道而降低进气道气动性能和稳定性的问题。
