Airplane deicing method and deicing device

Abstract

The invention belongs to the technical field of aircraft deicing, and particularly relates to an aircraft deicing method and device. According to the airplane deicing method, a reactant and an oxidizing agent are sprayed into a reaction chamber formed by a shell and an airplane skin, the reactant and the oxidizing agent react under the action of an igniter to generate gas and high temperature, impact loads generated by the high-temperature gas act on the airplane skin, and ice on the airplane skin is removed under the coupling action of vibration and heating. The high-temperature gas generated by the reaction of the oxidizing agent and the reactant instantly expands and acts on the aircraft skin to remove ice on the aircraft skin, the aircraft skin is rapidly heated, the thermal-mechanical coupling effect is remarkable, and the deicing effect is better.

Description

technical field [0001] The invention belongs to the technical field of aircraft deicing, and in particular relates to an aircraft deicing method and a deicing device. Background technique [0002] When the aircraft flies over the icy clouds, icing will occur on the fuselage, wings, etc., which seriously affects the flight safety of the aircraft. Therefore, in order to prevent the aircraft from icing or remove the icing of the aircraft, most of the aircraft are equipped with anti-icing devices. , de-icing device or anti-de-icing device. [0003] Existing deicing devices mostly use vibration or heating to remove ice. The vibration method is mainly electromagnetic excitation, and the heating method is mainly electric heating. These vibration and heating methods also have some disadvantages, which limit the application of vibration and heating deicing methods, for example: (1) The electromagnetic excitation power supply and control system are complex and heavy, and it is diffic...

Problems solved by technology

These vibration and heating methods also have some disadvantages, which limit the application of vibration and heating deicing methods, for example: (1) The electromagnetic excitation power supply and control system are complex and heavy, and it is difficult to apply them to aircraft with small carrying capacity; (2) Electric heating takes a long time, consumes a lot of energy, and the utilization rate of electric energy is low; (3) The supporting equipment is complex and costly

Therefore, the current vibration and heating methods are difficult to apply to small aircraft / drones with small load capacity or models with strict energy consumption requirements
