The invention discloses an embedded microchannel array and an aircraft, which are driven by energy of airflow in a boundary layer, and low-energy fluid is guided to flow into a microchannel by designing the microchannel with embedded inlet characteristics and is discharged to two sides of an aircraft body through the microchannel. Therefore, the adverse coupling effect between the low-energy fluid in the boundary layer and the main flow is cut off, self-driven migration of the low-energy flow of the aircraft forebody is flexibly achieved, and therefore the aerodynamic performance of the air inlet channel is improved. The embedded micro-channel designed by the design method is highly fused with an aircraft body, and the surface of the embedded micro-channel in the incoming flow direction has no protrusions. Compared with a traditional boundary layer displacement method, the method has the advantages of being passive, small in windward area, small in flow resistance and the like.
本发明公开了一种埋入式微通道阵列及飞行器,利用边界层内气流自身能量进行驱动,通过设计具有埋入式入口特征的微通道,引导低能流体流入微通道,并经由微通道排移至机体两侧,以此隔断边界层内的低能流体与主流之间的不利耦合作用,灵活实现飞行器前体低能流的自驱动迁移,从而提升进气道的气动性能。本设计方法设计出的埋入式微通道与飞行器机体高度融合,沿来流方向表面无任何凸起。与传统边界层排移方法相比,其具有无源、迎风面积小、流动阻力小等优点。
