The invention discloses a wing with a high lifting force, belonging to the technical field of air vehicles and relating to a wing. The wing comprises a wing body and a blade rotator, wherein a groove is formed in the upper surface of the wing body, and the blade rotator is arranged in the groove and is located between a root end plate and a tip end plate; the blade rotator comprises a main shaft, a central half-tooth gear and two, three or four rotating blades which are uniformly distributed at the periphery of the central half-tooth gear and have the same structure; the main shaft is horizontally arranged and is vertical to the root end plate and the tip end plate; the central half-tooth gear is arranged on the root end plate; the main shaft is connected with the central half-tooth gear through a bearing; power is input from the left end of the main shaft; each rotating blade comprises an arm shaft, a left blade shaft, a center-near gear, an arm shaft sleeve, a center-far gear, a blade gear, a blade, a right blade shaft and a rotating arm; the transmission ratio of the central half-tooth gear to the blade gear is 1:1; and the blade of the rotating blade and the arm shaft are located in the same vertical plane in the horizontal direction when the arm shaft of the rotating blade is located right above the main shaft. The wing can generate a relatively high lifting force so as to be suitable for a low-speed air vehicle.
