Abstract

The invention discloses a one-way conduction plasma suction device that can be used for wing drag reduction. The air port and the exhaust port of the device are respectively connected with the internal cavity of the insulating shell, and the external gas can enter the internal cavity of the insulating shell through the air inlet of the device and then flow out from the exhaust port of the device; the internal cavity of the insulating shell It consists of a number of first cavities connected in sequence in a linear arrangement. An ion plasma exciter is arranged on the inner wall of each first cavity, and two ion plasma exciters are arranged on the inner wall of the air inlet of the device. Two plasma exciters are arranged on the inner wall of the exhaust port. 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. ...
