The invention provides a novel propeller utilizing a Magnus effect. The novel propeller comprises blades, a propeller shaft, a propeller hub and a blade autorotation driving mechanism, wherein the propeller hub comprises a propeller hub base plate fixed at the end part of the propeller shaft, and a plurality of propeller hub bosses which are uniformly distributed and fixed on the propeller hub base plate, and the propeller hub base plate and the propeller shaft are coaxial; blade root connecting shafts penetrate through bearing holes and are in bearing fit with the corresponding propeller hub bosses; the blade autorotation driving mechanism comprises a motor, a main bevel gear and auxiliary bevel gears, an output shaft of the motor drives the main bevel gear to rotate, and the auxiliary bevel gears are equal to the blades, coaxially fixed on the end parts of the corresponding blade root connecting shafts and meshed with the main bevel gear. As the novel propeller utilizes the Magnus effect, when the propeller revolves at a constant speed, the pressure difference between the upper surfaces and the lower surfaces of the blades can be changed to the utmost through adjusting the autorotation speed of the blades, and as a result, a large pulling force is generated even at an extremely low revolution speed.
