Abstract
The present invention provides a hypersonic large internal contraction ratio air inlet channel having stepless adjustable air release valve, including an air inlet channel front body, an air-discharging slit cover plate, sidewalls, a lip cover, air-discharging cavities, valve plates, partition plates, a rotatable shaft, an expansion section and a driver. The valve plates are rotated through the driver according to the actual working conditions of air inlet channel, the minimum cross-section of the air discharging flow path is thus changed, and a stepless dynamic adjustment of the air discharging flow of the air inlet channel can be realized, so that the aerodynamic performance of the air inlet channel is improved, and the air discharging resistance of the air vehicle is reduced.
