Device and method for realizing aircraft flow control based on plasma exciter

Abstract

The invention discloses a device and a method for realizing aircraft flow control based on a plasma exciter. The device comprises a dielectric barrier discharge exciter, a plasma synthetic jet exciter, an insulating medium and a high-voltage power supply, the dielectric barrier discharge exciter comprises a high-voltage electrode block and a grounding electrode block; the plasma synthetic jet exciter comprises a first electrode bar and a second electrode bar, the insulating medium is penetrated by the first hole and the second hole, the high-voltage electrode block is located on the upper surface of the insulating medium, the grounding electrode block is located in the insulating medium, an internal cavity of the second hole forms an exciter cavity, and the first electrode bar and the second electrode bar respectively extend into the exciter cavity from the insulating medium. Jet flow generated by the dielectric barrier discharge exciter can be used for controlling separation of a flowfield on the surface of an aircraft, reducing flight resistance and improving lift force; jet flow generated by the plasma synthetic jet flow exciter can be used for changing the flight attitude of the aircraft and providing thrust required by flight.

Description

technical field

[0001] The invention belongs to the field of flow control of an external flow field of an aircraft, and in particular relates to a device and method for realizing flow control of an aircraft based on a plasma actuator. Background technique

[0002] Nowadays, various aircrafts develop rapidly and are gradually applied in our life. People's requirements for the performance of aircraft are also getting higher and higher, specifically manifested in fast flight speed, drag reduction and noise reduction, energy saving and high efficiency, and maneuverability. Existing aircraft wings are prone to airflow separation when the angle of attack is large, so that the wings lose sufficient lift prematurely, which threatens the safety of the aircraft. The active flow control actuator is essentially an energy conversion device, which realizes the manipulation of the external flow field by converting the input chemical energy, electrical energy, mechanical energy, etc. into ...
