Abstract

The invention provides an airplane metamaterial skin used for microwave heating ice prevention and removal. An FR4 material or a polyimide material serves as a dielectric layer, various parameters of the dielectric layer and a metal pattern layer are determined through the finite element method, the dielectric layer and metal patterns are sequentially arranged on the inner side face of a metal skin, then the skin can completely absorb microwaves at a specific frequency point and convert the microwaves into the heat on the surface of the skin, and accordingly ice layers on the surface of the skin can be melted and removed. By the adoption of the airplane metamaterial skin, the heat consumed on the ice prevention and removal skin is reduced, and the heat transmission efficiency and the heat utilization ratio are improved.

Description

technical field [0001] The invention relates to the technical field of microwave heating anti-icing / deicing, in particular to an aircraft supermaterial skin for microwave heating anti-icing and a manufacturing method thereof. Background technique [0002] The icing on the outside of the aircraft, especially the icing on the wing surface will seriously affect the flight safety. Even very fine ice particles may cause the deterioration of the aerodynamic performance of the aircraft wing, which may cause the aircraft to stall or cause safety accidents. Studies have shown that even if frost particles or ice particles with a diameter of 1-2 mm are distributed on the surface of the wing, assuming that the distribution density is only 1 / cm 2 , will also make the maximum lift coefficient loss of the aircraft by 22% to 33%, causing flight hazards. Therefore the anti-icing of aircraft is very important for the safe flight of flight. [0003] At present, the commonly used heating ant...
