Bionic hydrophobic anti-icing wing

Abstract

The invention discloses a bionic hydrophobic anti-icing wing, and the wing comprises a carbon fiber skeleton, a carbon fiber cloth skin, and a super-hydrophobic coating; the carbon fiber cloth skin wrapping the outer layer of the carbon fiber skeleton and the super-hydrophobic coating sprayed on the surface of the wing skin, and the super-hydrophobic coating has different surface microstructures at different positions of the wing. Through the combined action of the wing framework, the wing skin and the surface super-hydrophobic coating, the wing has the advantages of high strength, light weight and excellent hydrophobic anti-icing performance, solves the problems that when the wing works in a rainy and snowy weather environment, rainwater on the surface is difficult to slide off quickly, the wing is iced and normal work of an airplane is influenced; meanwhile, the problem that due to the fact that long-time rainwater residue causes the phenomenon of oxidation corrosion on the metal surface of the wing, the service life is influenced is solved.

Description

technical field [0001] The invention relates to the field of bionic technology, in particular to a bionic hydrophobic anti-icing wing. Background technique [0002] Today, with the increasing development of aviation technology, the problem of icing on aircraft wings has become an important problem hindering the development of aircraft. After the wing is icy, the structure of the upper and lower surfaces of the wing will change, which will affect the flow of the airflow, and then affect the flight stability of the aircraft. The traditional wing deicing methods, common ones are electric heating deicing and spraying antifreeze before flight, but they all belong to the solution after icing and can no longer meet the actual needs in terms of energy consumption and environmental protection, so the development of Effective new anti-icing technology is a major research hotspot in academia. Among them, the superhydrophobic surface has excellent anti-icing properties and has receive...
