Method and device for assisting aircraft in landing decelerating or takeoff boosting

Abstract

The invention relates to a method and device which can assist an aircraft in decelerating in the landing sliding process or assist the aircraft in boosting in the takeoff sliding process. At least oneset of landing and takeoff assisting system is arranged on a runway or beside the runway, and each landing and takeoff assisting system is at least composed of an elastic force generating part, a unidirectional movement control part and a contact part. The elastic force generating parts can cooperate with one another through the contact parts and a stress part on the aircraft, and then the aircraft can be decelerated as soon as possible after landing. The stress part comprises a wheel carrier of the aircraft. The unidirectional movement control parts can control the elastic force generating parts or the contact parts to not reset after displacing or reset only at the set time point or reset only when the elastic force generating parts or the contact parts arrive at the set positions or reset only when the set tension value is achieved. Power parts capable of driving the elastic force generating parts to stretch are arranged on the unidirectional movement control parts or arranged nearby the unidirectional movement control parts. When control of the unidirectional movement control parts over the elastic force generating parts or contact parts is relieved, quick resetting of the elastic force generating parts can be achieved in the mode that the contact parts or the stress part on the aircraft pulls or pushes the aircraft, and then the aircraft is assisted in taking off.

Description

Technical field [0001] The present invention relates to a method for landing or take-off of an aircraft, in particular to a method capable of slowing down the aircraft as soon as possible when landing or increasing power during takeoff. [0002] The present invention also relates to a device, especially a device that can help the aircraft to decelerate in landing or assist in take-off. Background technique [0003] At present, there are mainly the following methods to slow down the landing of aircraft in the world: 1. Build a runway long enough to allow the aircraft to stop due to the disappearance of the inertia of motion. This method is primitive and requires a long runway. 2. Install the speed brake and reverse thrust reduction device on the aircraft. The braking effect of this approach is limited. 3. Use brakes to decelerate. The disadvantage of this method is: because the aircraft is very fast when landing, the brakes made of ordinary materials cannot withstand the high temp...

This approach has limited braking effect

3. Use brake parts to decelerate. The disadvantage of this method is: due to the extremely fast speed when the aircraft lands, the brake parts made of ordinary materials cannot withstand the high temperature generated by friction during braking, so this kind of brake parts must be made of special materials. Difficulty and cost are high

4. Use the deceleration parachute to decelerate. The cost of this method is relatively low, but the process of retrieving and folding the deceleration parachute is cumbersome

[0007] As early as the beginning of the last century, the British invented a catapult that used springs and slides to assist flight. However, the technology at that time was relatively backward, and the intelligent comprehensive control system could not keep up. It was only applicable to light-weight propeller aircraft.

However, the information does not show that they have ever conducted experiments using springs and slides to assist in landing, nor have they ever shown that anyone has used the energy generated and accumulated in assisting in landing to assist in flight.
