Method and device for assisting landing deceleration or takeoff augmentation of aircraft

Abstract

The invention relates to a method and device for assisting the landing deceleration or takeoff augmentation of an aircraft. An air pressing piece or a hydraulic piece or a blocking piece or a brakingpiece is arranged on an airport runway or beside the runway or below the ground of the runway, a piston or an ignition device or a flow guide pipe or a flow guide hole or a driving cylinder or a driven cylinder is arranged on the air pressing piece or the hydraulic piece, and the gliding speed or the gliding distance of the aircraft after landing is controlled by controlling the flow of gas or liquid in the flow guide pipe or the flow guide hole. The piston in the driving cylinder can move by adopting a spiral lifting mode, a pulley lifting mode, a winch lifting mode, an air pressure pushing mode, a hydraulic pushing mode, a high-pressure pushing mode generated by burning fuel, a physical explosion pushing mode or a chemical explosion pushing mode, so that the piston in the driven cylinderis driven to move, vacuum is formed in a cavity of the driven cylinder to generate atmospheric pressure, and the atmospheric pressure is used for assisting the aircraft to catapult and take off.

Description

technical field [0001] The invention relates to a method and a device for helping an aircraft to land or take off, in particular to a method and a device capable of decelerating the aircraft as soon as possible when landing or increasing the thrust when taking off. Background technique [0002] At present, the ways to slow down the landing of aircraft in the world mainly include the following: 1. Build a long enough runway to allow the aircraft to stop automatically due to the disappearance of motion inertia. This method is relatively primitive and requires a very long runway. 2. Install speed brakes and reverse thrust deceleration devices on the aircraft. This approach has a limited braking effect. 3. Use brake parts to decelerate. The disadvantage is: due to the extremely fast speed of the aircraft when it lands, the brake parts made of ordinary materials cannot withstand the high temperature generated by friction during braking. Therefore, this kind of brake parts must b...

AI Technical Summary

Problems solved by technology

The braking effect of this method is limited

3. Use brake parts to decelerate. The disadvantage is: due to the extremely fast speed of the aircraft when it lands, the brake parts made of ordinary materials cannot withstand the high temperature generated by friction during braking. Therefore, this kind of brake parts must be made of special materials, and the manufacturing process is difficult and expensive. are very high

4. Using the parachute to decelerate, the cost of using this method is relatively low, but the process of recycling, folding and backing up the parachute is cumbersome

The disadvantages of this technology: First, there are many parts required, and the body shape is relatively cumbersome

The second is that it is not directly applied to the take-off of the aircraft, and the energy will be lost in the transmission and conversion of various components.

The third is that it can only help the plane take off, but it does not involve how to slow down the plane when it lands
