Abstract

The invention discloses a one-way conduction plasma air suction device capable of being used for wing drag reduction. The device comprises an insulating shell; a device air inlet and a device air outlet are formed in the two opposite ends of the insulating shell correspondingly, and the device air inlet and the device air outlet communicate with an inner cavity of the insulating shell correspondingly; external gas can enter from the device gas inlet, flows through the inner cavity of the insulating shell and then flows out from the device gas outlet; an inner cavity of the insulating shell is composed of a plurality of first cavities which are linearly arranged and sequentially communicated; one plasma exciter is arranged on the inner wall of each first cavity; two plasma exciters are arranged on the inner wall of the device air inlet; and two plasma exciters are arranged on the inner wall of the device air outlet. The device can reduce the frictional resistance of the wing surface.

Description

technical field [0001] The invention belongs to the technical field of plasma active flow control, and in particular relates to a one-way conduction plasma suction device which can be used for drag reduction of wings. Background technique [0002] At present, most of the drag reduction devices based on the principle of plasma aerodynamic excitation are a series of arrays of plasma actuators arranged on the upper surface of the wing or flat plate along the direction of the incoming flow or perpendicular to the direction of the incoming flow. By reducing the number of low-velocity strips of large-scale vortex coherent structures within the unit span area of ​​the wing surface, inhibit the self-sustaining circulation process of the flow direction vortex, inhibit the development of the turbulent burst process, reduce the intensity and frequency of the turbulent burst, and delay the laminar flow state of the surface flow , so as to achieve the effect of turbulent drag reduction. ...
