Aircraft wheel and landing-assisting method

Abstract

The invention discloses an aircraft wheel and a landing-assisting method. The aircraft wheel comprises a tire, an outer hub and a core part, wherein the tire is arranged on the outer hub in a sleeving manner; the core part is arranged in a cavity of the outer hub; a plurality of pieces of permanent magnet steel are arranged on the inner surface of the outer hub; the core part comprises a plurality of coil groups, a brake resistor, a controller and a wheel shaft; the plurality of coil groups are distributed in the outer edge area of the core part and correspond to the plurality of pieces of permanent magnet steel; the controller is electrically connected with the plurality of coil groups and the brake resistor respectively; the wheel shaft is located on the central axis of the core part; the outer hub is arranged on the wheel shaft in a sleeving manner; the core part further comprises a stator iron core and a fixed frame, the stator iron core is arranged on the fixed frame in a sleeving manner, the plurality of coil groups are arranged on the stator iron core, and the wheel shaft is arranged at the center of the fixed frame. The aircraft wheel is capable of effectively reducing the slide friction force and the deflection torque stressed by contacting to earth when an aircraft lands, thus greatly improving the safety.

Description

technical field [0001] The invention relates to an aircraft wheel and a method for assisting landing. Background technique [0002] When the plane lands, the tires of the plane will accelerate from static to the landing speed of the plane (generally 250-350Km / h) in a very short time after touching the ground, which will cause damage to the tires, hubs and bearings of the plane wheels. extreme shock loads. In the initial stage of tire movement, the tire rotates rapidly as soon as it touches the ground, but the rotation speed does not reach the grounding speed of the aircraft, so the tire is still in a state of sliding friction when it rotates. On the one hand, sliding friction generates a large amount of heat, causing the tire surface to be worn or worn out rapidly, and even cause the wheel tire to burst, endangering flight safety; on the other hand, it is strictly impossible for the main wheels on both sides of the aircraft to touch the ground at the same time , the wheel ...

Problems solved by technology

On the one hand, sliding friction generates a large amount of heat, which causes the tire surface to be worn or worn out rapidly, and even causes the wheel tire to burst, endangering flight safety; on the other hand, it is strictly impossible for the main wheels on both sides of the aircraft to touch the ground at the same time , the wheel that touches the ground first will form a deflection moment relative to the center of gravity of the aircraft, causing a safety accident
