Light and flexible fixed-wing aircraft side wing flap

The utility model discloses a light and flexible fixed wing aircraft side wing flap. The aircraft comprises aircraft propellers and an aircraft body, the aircraft propeller is fixedly installed in themiddle of the front end of the aircraft body. The side wing flap composed of the side edge connecting component, the metal wing shell, the triangular reinforcing block and the reinforcing cross rod is not prone to deformation in the high-speed flight process. High-speed flight, by means of the reinforcing cross rods and the triangular reinforcing blocks in the metal wing shell, good supporting strength is achieved for the outside, deformation is not prone to occurring during high-speed flight, the triangular reinforcing blocks and the reinforcing cross rods are made of novel alloy materials and have the advantages of being high in strength and low in weight, and therefore use control is more flexible. And the side edge connecting component is fixedly arranged in the middle of the triangular reinforcing block, so
