Problems solved by technology

This phenomenon has been partially used, but through the inspection of multiple airfoil patents and existing airfoil objects, it is found that when the airfoil is working, the drag of the airfoil is caused by the forward movement of the Magnus roller that provides lift. Increase, although some patents have made improved designs to reduce resistance to the aforementioned problems, but none of them can solve the above problems

Abstract

The invention discloses a lifting-force-reinforced wing section based on the Magnus principle. The lifting-force-reinforced wing section comprises a front wing body, a Magnus cylinder and a tail wing body; the longitudinal ends of the front wing body and the longitudinal ends of the tail wing body are respectively, vertically and fixedly connected with opening sealing bodies to form the lifting-force-reinforced wing section with the cross section in a streamline shape; the Magnus cylinder is embedded between the front wing body and the tail wing body, and a driving device of the Magnus cylinder is arranged in one opening sealing body and the tail wing body; and a plurality of air inlet pipe horizontally penetrating through the front wing body are longitudinally arranged in the front wing body at intervals. The Magnus cylinder is embedded between the front wing body and the tail wing body, so that wing wake flow is improved, and tail vortex is reduced. Furthermore, the Magnus cylinder is convenient to install, disassemble and replace. The air inlet pipes on the upper side of the central line of the Magnus cylinder can supplement the air volume to guarantee that the Magnus cylinder can generate pressure difference. Thus, the lifting force can be further reinforced.

Description

technical field [0001] The invention relates to a device for increasing the lift of an airfoil, in particular to a device for increasing the lift of an airfoil by using the Magnus effect, and belongs to the technical fields of aerospace and ship engineering. Background technique [0002] The airfoil structure is widely used in aircraft and ship engineering. When sailing at high speed, the aircraft or hydrofoil can provide lift through the airfoil to lift the aircraft off the ground or lift the hydrofoil out of the water to reduce navigational resistance. [0003] The Magnus principle refers to a phenomenon in which a rotating cylinder moving in a viscous incompressible fluid is subjected to a lifting force. This phenomenon has been partially used, but through the inspection of multiple airfoil patents and existing airfoil objects, it is found that when the airfoil is working, the drag of the airfoil is caused by the forward movement of the Magnus roller that provides lift. ...
