Dielectric barrier discharge plasma anti-icing device and method

Abstract

The invention discloses a dielectric barrier discharge plasma anti-icing device and method. A plurality of layers of polyimide adhesive tape are overlapped and pasted to serve as an insulation layer. Upper electrodes and lower electrodes are pasted along the two side faces of the insulation layer in a staggered mode. The upper electrodes are connected in parallel to be connected with a positive electrode of a plasma power source. The lower electrodes are connected in parallel to be connected with a negative electrode of the plasma power source. The insulation layer is fixed into a groove in the surface of an aircraft skin, and efficient anti-icing of the surface of an aircraft is achieved. Due to the fact that the thickness of the electrodes and the thickness of the insulation layer are very small, the effect of the electrodes and the insulation layer on the aerodynamic performance of the aircraft can be ignored. The dielectric barrier discharge plasma anti-icing device is simple in structure, and the electrodes can be flexibly distributed according to the different geometrical shapes of the frozen positions of the aircraft. When the voltage of the plasma power source is adjusted to 70 V and the current strength ranges from 1.5 A to 2.5 A, the voltage actually loaded to the electrodes can reach 10 KV or more, the responding time is short, the anti-icing effect is good, the implement method is convenient to implement and easy to achieve and has good application prospects, and no pollution exists.

Description

technical field

[0001] The invention relates to a device and method for anti-icing on the surface of an aircraft, in particular to an anti-icing device and method using dielectric barrier discharge plasma. technical background

[0002] When the aircraft passes through the clouds containing supercooled water droplets, the windward parts of the aircraft, such as windshield glass, wings, rotors, vertical tails, engines, etc., will freeze without anti-icing systems, and the key parts of the aircraft Icing has become a major hidden danger in flight safety. The icing on the key parts of the aircraft will change the aerodynamic shape of the aircraft, seriously affect the aerodynamic characteristics of the aircraft, and deteriorate the maneuverability and stability of the aircraft. The angle of the windshield is reduced, and the handling performance is reduced; the icing of the engine will directly affect the normal operation of the engine and greatly reduce the efficiency of the e...
