The invention discloses a helicopter embedded air inlet channel with a power output shaft. The air inlet channel is located in an engine compartment below a helicopter rotor hub, an inlet and the engine compartment are fused, no convex surface exists, and the inner profile of the air inlet channel is bent towards the symmetrical plane direction of the helicopter, so that the whole blade cannot be seen from the inlet direction. The power output shaft is located in the center of the air inlet channel pipeline and penetrates through the flow guide face of the embedded air inlet channel to be connected with the rotor wing speed reducer so as to weaken rotational flow generated by induction of the power output shaft and achieve forward power output. The characteristics of low external resistance and high invisibility of the embedded air inlet channel are fully utilized, the aerodynamic performance and the invisibility of the air inlet channel are both considered, and the embedded air inlet channel is particularly suitable for high-speed and high-invisibility military helicopters.
本发明公开了一种带功率输出轴的直升机埋入式进气道。进气道位于直升机旋翼桨毂下方发动机舱内,且进口和发动机舱融合,没有任何外凸表面,进气道内型面往直升机对称面方向弯曲,使得从入口方向无法看全叶片。功率输出轴位于进气道管道中心,并穿过埋入式进气道导流面和旋翼减速器相连,以削弱功率输出轴诱导产生的旋流,实现前向功率输出。本发明充分利用了埋入式进气道低外阻、高隐身的特点,兼顾了进气道的气动性能和隐身性能,特别适合高速、高隐身军用直升机。
