Ultra-short-distance landing system of fixed-wing unmanned aerial vehicle

Abstract

The invention discloses an ultra-short-distance landing system of a fixed-wing unmanned aerial vehicle, and particularly relates to the shortening of a skating distance after the fixed-wing unmanned aerial vehicle flies and lands. According to the system provided by the invention, in an electromagnetic field environment, the fixed-wing unmanned aerial vehicle generates Ampere force through skating, so that the fixed-wing unmanned aerial vehicle quickly slows down and stops stably in an ultra-short distance. The ultra-short-distance landing system of the fixed-wing unmanned aerial vehicle comprises a composite power supply module, the fixed-wing unmanned aerial vehicle, an airborne ampere force generating device, an airborne ampere force generating device control module, an airborne signal receiving device, a ground sensor device, a ground signal transmitting device, a ground magnetic field generating device and a ground magnetic field generating device control module. The composite power supply module provides a stable high-current large-turn rectangular circuit for the frame of the wing of the fixed-wing unmanned aerial vehicle, the fixed-wing unmanned aerial vehicle lands in the environment of the ground magnetic field generating device, the wing continuously cuts the magnetic field, Ampere force opposite to the skating direction is generated, and acceleration opposite to the movement direction is provided, so that the effect of rapid short-distance arresting is achieved. The ultra-short-distance landing system for the fixed-wing unmanned aerial vehicle has the advantages that the effective acceleration is large during landing, the deceleration effect is outstanding, the landing effect is improved, and the landing time is shortened.

Description

technical field [0001] The invention relates to an ultra-short-distance landing system for a fixed-wing unmanned aerial vehicle, in particular to shortening the sliding distance of the fixed-wing unmanned aerial vehicle after landing. Background technique [0002] At present, there are four ways for fixed-wing UAVs to land and decelerate. The first is wheel sliding friction deceleration, which is the most commonly used deceleration method. Stopping steadily requires a long runway; the second type of power reverses the thrust to slow down. When the fixed-wing UAV taxis, its engine ejects high-speed airflow backwards, generating reverse thrust to make it decelerate quickly, which consumes a lot of energy; the third type increases air Resistance decelerates. When landing, the fixed-wing UAV lowers the leading edge flap, which increases the air resistance of the aircraft.

[0002] At present, there are four ways for fixed-wing UAVs to land and decelerate. The first is wheel sliding friction deceleration, which is the most commonly used deceleration method. Stopping steadily requires a long runway; the second type of power reverses the thrust to slow down. When the fixed-wing UAV is taxiing, its engine ejects high-speed airflow backwards, generating reverse thrust to make it decelerate quickly, which consumes a lot of energy; the third type increases air Resistance decelerates. When landing, the fixed-wing UAV lowers the leading edge flap, which increases the air resistance of the aircraft. Large-scale fixed-wing UAVs are often used, and small fixed-wing UAVs are inconvenient to use.

The fourth is to use the arresting cable to decelerate. When the fixed-wing UAV is about to land, put down the tail hook, hook the arresting cable at the end of the runway, and use the huge pulling force of the arresting cable to quickly decelerate until it stops. success

Among the four deceleration methods, none of them are enough to make the fixed-wing UAV stand still quickly, the deceleration effect is insufficient, the implementation conditions are many restrictions, the operation is difficult, and there are many preparations before and after landing, etc.
