Embedded air intake structure and aircraft
By designing an embedded air intake structure, the air intake is located above the bottom wall of the air intake and smoothly transitions with the wing. Combined with the grille and exposed bottom wall, the radar echo problem caused by the exposed air intake of the tiltrotor aircraft is solved, improving air intake efficiency and radar stealth performance.

AI Technical Summary
Technical Problem
The exposed air intake of a tiltrotor aircraft makes it easy for radar waves to enter the air intake, generating strong radar echoes and affecting radar stealth performance.
Method used
Design an embedded air intake structure so that the air intake is located above the bottom wall of the air intake and below the highest point of the upper surface of the wing. Combine the grille and the exposed bottom wall to smoothly transition with the wing to form a streamlined structure, reducing the amount of radar waves entering the air intake.
Benefits of technology
It improves air intake efficiency, reduces radar echo, enhances radar stealth performance, and lowers radar cross section.

Abstract
This invention provides an embedded air intake structure, relating to the field of flight equipment. It includes an air intake body with a bottom wall and an air inlet. The bottom wall of the air intake body is fixedly connected to the trailing edge of an aircraft wing. The upper surface of the bottom wall of the air intake body is streamlined, allowing for a smooth transition with the upper surface of the wing. The opening of the air intake body near the wing end serves as the air inlet. When the aircraft is in horizontal flight, the air inlet is located above the bottom wall of the air intake body and below the highest point of the upper surface of the wing. This invention also provides an aircraft, including a wing, a fuselage, and the aforementioned embedded air intake structure. The bottom wall of the air intake body is fixedly connected to the trailing edge of the wing, and the wing is fixedly connected to the fuselage. The embedded air intake structure and aircraft provided by this invention can improve air intake efficiency, reduce strong radar echoes, and improve radar stealth performance.
