Supersonic-speed deformable bulge air inlet channel and control method

The invention discloses a supersonic-speed deformable bulge air inlet channel and a control method. Comprising a front body, a lip cover, a deformable bulge connected with the rear end of the front body and located on the inner side of the lip cover, a downstream diffusion section connected with the rear end of the deformable bulge and extending backwards, a cavity located on the inner side of the deformable bulge, and an inflation and deflation device for inflating and deflating a closed cavity. A metal supporting piece for supporting the deformable bulge is arranged on the inner surface of the deformable bulge, and the metal supporting piece is provided with a plate piece which protrudes outwards and is attached to the deformable bulge, so that the deformable bulge forms an initial bulge molded surface; a plurality of communicating holes are formed in the plate, a plurality of distributed supporting columns are arranged in the closed cavity, the tops of the distributed supporting columns penetrate through t
