Problems solved by technology

This is because the electric energy provided by the power generation equipment on the aircraft is far from meeting the requirements of the large-scale application of electric heating anti-icing technology, so the electric heating anti-icing technology has certain limitations in the applicability of aircraft

Embodiment Construction

[0026] The present invention will be further described below. see figure 1 , for existing aircraft, the anti-icing position generally needs to include the leading edge of the wing and the leading edge of the empennage.

[0027] An ultrasonic and electric heating composite anti-icing device, such as figure 2 shown, including:

[0028] Icing signal device 1, electric heating assembly 3, ultrasonic oscillator 4, ultrasonic controller 5, anti-icing control box 6;

[0029] The icing signal device 1 is used to detect whether the aircraft has entered the icing area, and if it enters the icing area, an icing warning signal and icing rate information are sent to the anti-icing control box 6 through the signal line 2;

[0030] The anti-icing control box 6 is used to send a pulse heating signal to the electric heating component 3 first according to the icing alarm signal and the icing rate information, and then send the start work command to the ultrasonic controller 5;

Abstract

The invention belongs to the field of aircraft anti-icing and de-icing, and proposes an ultrasonic and electric heating composite anti-icing device, including: an icing signal device 1, which is used to detect whether the aircraft has entered the icing area, and if it enters the icing area, Send the icing alarm signal and icing rate information to the anti-deicing control box 6 through the signal line 2; the anti-icing control box 6 is used to send a pulse heating signal to the electric heating component first according to the icing alarm signal and icing rate information 3, and then send the start work command to the ultrasonic controller 5; the electric heating component 3 is used to heat the skin of the icing protection area according to the pulse heating signal; the ultrasonic controller 5 is used to oscillate to the ultrasonic wave according to the start work command The device 4 sends a work order; the ultrasonic oscillator 4 is used to turn on the ultrasonic wave on the skin of the icing protection area according to the work order. Short deicing time and low energy consumption.

Description

technical field [0001] The invention belongs to the field of aircraft anti-icing and deicing, and relates to an anti-icing and deicing device. Background technique [0002] When an aircraft flies in clouds containing supercooled water droplets, many parts will freeze, such as wings, leading edge of tail, propeller, engine air intake, windshield, etc. The icing of the aircraft will destroy the aerodynamic shape of the aircraft, hinder the flow of air, increase the friction and reduce the lift, especially the ice on the wings and tail has a greater impact on the aircraft, which will not only make the lift and drag characteristics Deterioration, but also reduce the flight safety of the aircraft, and even cause accidents of aircraft crashes and fatalities. [0003] Electric heating anti-icing technology is currently widely used in domestic and foreign aircraft, mainly for anti-icing on the tail of the aircraft. Few aircraft wing anti-icing systems use electric heating anti-icin...
