The invention discloses a contra-rotating wheel rim propeller which comprises a support, a guide pipe, a pressure system, a power system and an electric system. The power system comprises a first power part, a second power part, a plurality of fixed shaft transmission gears and a baffle; an air pressure cavity is formed between the outer circumferential wall of a first flange hub in the first power part and the inner wall of the guide pipe, the baffle is arranged in the air pressure cavity, and when the reciprocating partition plate moves to make contact with the outer circumferential wall of the first flange hub, the air pressure cavity is divided into a first air pressure cavity and a second air pressure cavity through the baffle and the reciprocating partition plate. According to the power system, the rotation directions of the two sets of hubs are opposite in a gear transmission mode. The edge hubs and the blades are driven to rotate through the pressure difference between the two air pressure cavities, a
