Autonomous intermittent deicing device and mounting method and deicing method thereof

Abstract

The invention belongs to the technical field of aircraft deicing, and particularly relates to an autonomous intermittent deicing device and a mounting method and a deicing method thereof. The autonomous intermittent deicing device comprises a plurality of memory material brackets and an electric heating module, and the plurality of memory material brackets are connected with the electric heating module; when the memory material brackets are arranged on the inner wall, the electric heating module has two states: wherein in the first state, the contact surface of the electric heating module is not in contact with the inner wall; in the second state, the contact face of the electric heating module makes contact with the inner wall. The electric heating module instantly and quickly heats the ice layer locally, and air pressure brought by vaporization of the contact surface of the ice layer and the inner wall can crush the ice layer in a large range; compared with slow heating in the priorart, the device has the advantage that the energy utilization rate of deicing in unit area is higher; and the device also has the advantage 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...
