The invention provides an embedded type air inlet channel structure, and relates to the field of flight equipment, the embedded type air inlet channel structure comprises an air inlet channel body, the air inlet channel body is provided with a bottom wall and an air inlet, the bottom wall of the air inlet channel body is used for being fixedly connected to the rear edge of a wing, and the upper surface of the bottom wall of the air inlet channel body is streamline; the upper surface of the bottom wall of the air inlet channel body can be connected with the upper surface of a wing and is in smooth transition with the upper surface of the wing, an opening, close to one end of the wing, of the air inlet channel body is an air inlet, and the air inlet is located above the bottom wall of the air inlet channel body and lower than the highest point of the upper surface of the wing when the aircraft flies horizontally. The invention further provides an aircraft which comprises wings, a fuselage and the embedded air inlet duct structure, the bottom wall of the air inlet duct body is fixedly connected to the rear edges of the wings, and the wings are fixedly connected with the fuselage. According to the embedded type air inlet channel structure and the aircraft, the air inlet efficiency can be improved; strong radar echoes are reduced, and radar stealth performance is improved.
本发明提供了一种埋入式进气道结构,涉及飞行设备领域,包括进气道本体,进气道本体具有底壁和进气口,进气道本体的底壁用于固定连接于机翼的后缘,进气道本体的底壁的上表面呈流线型,进气道本体的底壁的上表面能够与机翼的上表面衔接并平滑过渡,进气道本体靠近机翼一端的开口为进气口,当飞行器水平飞行时进气口位于进气道本体的底壁的上方且低于机翼的上表面的最高点。本发明还提供了一种飞行器,包括机翼、机身和上述的埋入式进气道结构,进气道本体的底壁固定连接于机翼的后缘,机翼与机身固定连接。本发明提供的埋入式进气道结构和飞行器能够提高进气效率;减少较强雷达回波,提高雷达隐身性能。
