Aircraft deicing device based on elastic skin

Abstract

The invention is applicable to the field of aircraft deicing, and particularly relates to an aircraft deicing device based on an elastic skin. The aircraft comprises the elastic skin, an actuating mechanism, a cam system and a motor, the elastic skin and the actuating mechanism are fixed on a wing through a connecting piece, and the actuating mechanism comprises an upper actuating mechanism and alower actuating mechanism; translation pieces are arranged on the upper actuating mechanism and the lower actuating mechanism, and the cam system drives the upper actuating mechanism and the lower actuating mechanism to do linear motion along an airfoil, so that different sections of the elastic skin are driven to be periodically stretched and deformed, accumulated ice and the elastic skin relatively slide in a staggered mode, so that the accumulated ice falls off. According to the actuating deicing device, the energy utilization rate of the actuating mechanism is high, and the service life ofthe motor cannot be influenced; the elastic skin is periodically stretched along the airfoil, and the elastic skin at the front edge of the airfoil can also drive the airfoil to generate certain elastic deformation, so that the deicing effect is greatly improved; and the elastic skin and the actuating mechanisms are fixed to the wing through the screws, the skin is easy to replace, and the sealing effect is good.

Description

Technical field [0001] The present invention relates to an aircraft de-refrigeration, in particular, involving an aircraft desert device based on elastic skin. Background technique [0002] When the plane is flying in the air, if you encounter frozen meteorological conditions, the surface of the air wing surface, the engine intake, and various types of sensors outside the aircraft fuselage will affect the flight safety. Therefore, the aircraft desert is a necessary condition for ensuring normal flight of the aircraft. Currently commonly used refrigeration methods include liquid de-refrigeration, mechanical deception and thermal ice such as ice, etc., although the above mode can achieve ice, there are some shortcomings, such as skin fabrics in liquid degeneration, liquid supply devices Complex; the airbag in the mechanical deception is degenerative, the air supply is complex, while the electrical pulse is high, the power supply is large, the power supply is large; the heat is less...

AI Technical Summary

Problems solved by technology

This method still has the following defects: 1. The motor needs to be rotated continuously, which affects the life of the motor; 2. The deformation of the elastic skin in the patent needs to be driven by the flexible rib 25, resulting in low energy utilization; 3. The general structure of the leading edge of the wing Ice is the most, and deformation is the least here in the patent, therefore, the deicing effect is poor

[0005] Therefore, even if there are some devices about elastic belt deicing in the prior art, the deicing effect of the existing deicing devices is poor, and the energy consumption is high, and the sealing performance is difficult to guarantee.
