Abstract

The invention proposes a combined deicing device and method with reduced adhesion force and a plasma high-energy exciter, aiming at saving deicing energy, reducing the weight and complexity of the deicing device, and improving the deicing effect. The invention includes a device for weakening adhesion, a plasma deicing device and a power control system, a device for weakening adhesion is arranged on the surface requiring deicing, and a high-energy plasma is arranged on the surface requiring deicing The exciter, the plasma high-energy exciter is connected to the power control system, and the power control system provides working power for the plasma high-energy exciter and controls the plasma high-energy exciter to work. When de-icing is performed, the adhesion of ice is first weakened, and then the plasma de-icing device is turned on to achieve the purpose of rapid ice-breaking with low energy consumption. Many devices in various fields have deicing requirements, and the present invention can be widely used in various fields and devices for deicing, such as aircraft, specifically, wings.

Description

technical field [0001] The invention belongs to the technical field of anti-icing, and relates to a combined deicing device and method using an adhesive force weakening and a plasma high-energy exciter, which are used to quickly break ice accumulation and save deicing energy. Background technique [0002] Icing is a phenomenon that widely exists in aircraft flight, and it is also one of the main hidden dangers that cause flight safety accidents. The icing on different parts of the aircraft will bring different degrees of harm to flight safety. The specific manifestations are: icing on the lift surface will lead to increased aircraft resistance, decreased lift, decreased stall angle of attack, increased stall speed, and maneuverability. Stability deterioration and other consequences; the icing of the intake duct will affect the intake characteristics of the engine, increase fuel consumption, reduce engine life, and even cause the engine to stall; when important instruments su...
