Problems solved by technology

[0002] As the main part of the aircraft to generate lift, the wing will change its flatness, shape and aerodynamic layout due to icing, which will lead to a decrease in the lift-to-drag ratio of the aircraft and cause serious harm to the flight safety of the aircraft.
The existing anti-icing methods for aircraft wings mainly include hot air anti-icing and electric heating anti-icing. Hot air anti-icing is to use the hot air generated by the engine to enter the leading edge of the aircraft's wing after a series of adjustments such as pressure, and Flowing along the leading edge channel of the aircraft wing, the heat is transferred to the inside of the wing inner skin of the aircraft wing during t

Embodiment 1

[0025] This embodiment provides an anti-icing device, such as Figure 1~2 As shown, the anti-icing layer 4 is included, and the anti-icing layer 4 is filled with a phase-change energy storage material. The phase-change energy storage material is in a liquid state, and the phase-change temperature of the phase-change energy storage material 5 is higher than the freezing point. The phase change energy storage material is filled in the anti-icing layer 4, and the phase change temperature of the phase change energy storage material 5 is higher than the freezing point temperature. When the ambient temperature drops to the freezing point temperature, the phase change energy storage material 5 can release heat. Prevent icing and remove the ice that has already formed. When the temperature rises, the phase change energy storage material 5 absorbs and stores heat, which can realize the recycling of the anti-icing layer 4 . In this embodiment, the anti-icing process of the anti-icing de...
