The invention discloses an air inlet channel of an aero-engine nacelle and the aero-engine nacelle. The air inlet channel of the aero-engine nacelle comprises an inner wall plate and a butt joint ring, the inner surface of the inner wall plate forms an air flow channel face, the outer surface of the inner wall plate comprises a first matching face, the butt joint ring is used for connecting the inner wall plate and a fan casing and comprises a second matching face, and the second matching face and the first matching face are attached to each other and connected. And the first matching surface and the second matching surface are single curved surfaces. The matching surface of the butt joint ring of the air inlet channel and the inner wall plate adopts a single curved surface, so that the butt joint ring is convenient to machine and manufacture. Moreover, when the butt joint ring and the inner wall plate are horizontally assembled and installed along the axis of the engine, the butt joint ring can be installed to a theoretical position from the rear end of the inner wall plate, and the assembling and installing path is shortened to the maximum extent.
本发明公开了一种航空发动机短舱的进气道和航空发动机短舱。航空发动机短舱的进气道包括内壁板和对接环,内壁板的内表面形成气体流道面且外表面包括第一配合面,对接环用于连接内壁板和风扇机匣,且对接环包括第二配合面,第二配合面与第一配合面相互贴合并连接,第一配合面和第二配合面均为单曲面。进气道的对接环与内壁板的配合面采用单曲面,方便对接环的机械加工制造。而且,在与内壁板沿发动机轴线水平装配安装时,对接环可从内壁板后端安装至理论位置,最大限度的缩短装配安装路径。
