An autonomous intermittent deicing device and its installation method and deicing method

Abstract

The invention belongs to the technical field of aircraft deicing, and in particular relates to an autonomous intermittent deicing device, an installation method thereof and a deicing method. One of the autonomous intermittent deicing devices includes a memory material support and an electric heating module. There are several memory material supports connected to the electric heating module; when the memory material support is arranged on the inner wall, the The electric heating module has two states; state one: the contact surface of the electric heating module is not in contact with the inner wall; state two: the contact surface of the electric heating module is in contact with the inner wall. The electric heating module heats the ice layer instantly and rapidly, and the air pressure brought by the vaporization of the contact surface between the ice layer and the inner wall can break the ice layer in a large range; compared with the slow heating in the prior art, the present invention has a higher energy utilization rate for deicing per unit area High advantages; and the present invention also has the advantages of simple and reliable structure.

Description

technical field [0001] The invention belongs to the technical field of aircraft deicing, and in particular relates to an autonomous intermittent deicing device, an installation method thereof and a deicing method. Background technique [0002] When an aircraft passes through clouds containing supercooled water droplets, the windward surfaces of many components may freeze, such as wings, tail leading edge, propellers, engine air intakes, sensor probes such as pitot tubes, windshields, etc. Components and rotor main and tail rotors can also freeze. In the absence of icing protection or improper protection, icing will deteriorate the lift-drag characteristics of the aircraft, reduce the stall angle of attack and stability margin, and reduce the maneuverability, resulting in engine flameout in mid-air and distortion of flight display data. [0003] It can be seen that the icing of the aircraft will not only affect the flight performance of the aircraft, but even threaten the fl...
