Mechanical structure of disc-shaped aircraft

The utility model discloses a mechanical structure of a disc-shaped aircraft. The structure comprises a cab, a double-layer hollow structure, an annular wing plate, a disc body, a cavity chamber, a chassis stabilizing fan, an inclination adjusting fan, a bearing structure, blades, a front notch, a rear notch, a channel and an outer-layer circular ring connector. The cab is fixedly connected with an upper shell and a lower shell of the disc body, and a closed cavity is formed between the upper shell and the lower shell of the disc body. The outer side wall of the cab is connected with an outer-layer circular ring connector of an annular wing plate through a bearing structure, and the annular wing plate covers an upper shell of the disc body, so that the annular wing plate can rotate relative to the cab; a blade is arranged on the annular wing plate, and a front notch and a rear notch are correspondingly formed below the blade; an outer-layer circular ring connecting opening is formed in the center of the annul
