The invention relates to a nacelle for accommodating an aircraft engine and an aircraft equipped with the nacelle. The nacelle comprises a lip located at the front end, a plurality of protrusions are arranged on the surface of the lip at intervals in the circumferential direction, the protrusions are located at the lip front edge, connected with the air inlet channel, of the outer wall of the nacelle, protrude relative to the surface of the lip and have the preset width in the circumferential direction, and the protrusions extend in the air inlet flowing direction, and the protruding height of the protrusions is gradually increased in the air inlet flowing direction. According to the invention, the front edge and the two sides of the protruding part arranged on the surface of the lip can form a flow direction vortex in the air flow, and the flow direction vortex can reduce the separation tendency of a boundary layer, so that the problem of air inlet distortion is reduced or avoided.

    本发明涉及一种用于容纳飞行器发动机的短舱及配备该短舱的飞行器。短舱包括位于前端的唇口,唇口的表面沿周向的至少一部分间隔地设置有多个突出部,该突出部位于短舱的外壁与进气道连接的唇口前缘处,相对于唇口的表面突出并具有沿周向的预定宽度,突出部沿进气流动方向延伸,并且突出部的突出高度沿进气流动方向逐渐增加。根据本发明,唇口表面设置的突出部的前缘和两侧能够在气流中形成流向涡,流向涡能够减小附面层的分离倾向,从而减小或避免进气畸变的问题。
