The invention relates to the technical field of air inlet channel flow control, and discloses a supersonic aircraft air inlet channel structure which comprises an air inlet channel body, the air inlet channel body is provided with an air inlet channel surface, the air inlet channel surface is provided with a first direction and a gas flowing direction, and the first direction is a set reference direction and intersects with the gas flowing direction; the lip-mouth mask is arranged outside the air inlet channel body at intervals, and an air duct is formed between the lip-mouth mask and the surface of the air inlet channel; the convex structure is arranged on the surface of the air inlet channel; the protruding structure comprises a plurality of protruding strips, the protruding strips extend in the first direction of the surface of the air inlet channel, and the protruding strips are sequentially connected in the air flowing direction of the surface of the air inlet channel, so that the section contour of the protruding structure in the air flowing direction is in a corrugated shape. Transition excitation is achieved by changing the geometric shape of the aircraft air inlet channel structure, external input energy is not needed, and therefore the aircraft air inlet channel structure is simplified, the maintenance cost and operation complexity of an aircraft are reduced, and the stability of an aircraft system is improved.
本发明涉及进气道流动控制技术领域,公开了一种超声速飞行器进气道结构,包括进气道本体,具有进气道表面,进气道表面具有第一方向和气体流动方向,第一方向为设定的参考方向,第一方向与气体流动方向相交;唇口罩,间隔设于进气道本体的外部,唇口罩与进气道表面之间形成通气道;凸起结构,设于进气道表面;凸起结构包括多个凸条,凸条沿进气道表面的第一方向延伸设置,多个凸条沿进气道表面的气体流动方向依次连接,以使得凸起结构沿气体流动方向上的截面轮廓呈波纹状。本发明通过改变飞行器进气道结构的几何外形实现转捩激励,不需要外界输入能量,从而简化飞行器进气道结构,降低飞行器维护的成本及操作复杂性,提高飞行器系统的稳定性。
