Embodiment 1

[0049] A fast take-off and landing system for a quadcopter on a vertical wall based on electrostatic adsorption, such as figure 1 and 3 As shown, it includes a four-axis aircraft 2, and two groups of elastic foot bionic structures respectively arranged on two adjacent axes of the four-axis aircraft 2, one end of the elastic foot bionic structure is installed on the motor of the four-axis aircraft 2 On the fuselage, one end of the elastic foot bionic structure extends out of the four-axis aircraft 2 and is connected to an electrostatic adsorption electrode 6, and a high-voltage electrostatic generator 7 is also installed on the four-axis aircraft 2 for generating high-voltage feed The electrostatic adsorption electrode 6 is charged, and the high-voltage electrostatic generator 7 can directly and conveniently obtain working power from the quadcopter 2 .

[0050] Among them, such as figure 2 As shown, the elastic foot bionic structure includes a flexible rod 5 and an elastic f...

Embodiment 2

[0054] This embodiment 2 provides a quick take-off and landing method based on the above-mentioned quadrocopter vertical wall quick take-off and landing system, such as Figure 5-10 Shown, the landing process of described quadrocopter 2 is:

[0055] The high-voltage electrostatic generator 7 generates high voltage to charge the electrostatic adsorption electrode 6;

[0056] When the quadcopter 2 is at an initial velocity v 0 When landing and colliding with the wall 1, the electrostatic adsorption electrode 6 contacts and adsorbs on the wall 1; until the elastic foot support 3 collides with the wall 1, a reverse acceleration is generated in its horizontal forward direction, triggering the quadcopter 2 Its own propeller turns off the thrust so that it loses lift;

[0057] At the same time the initial velocity v 0 The component velocity along the fuselage direction of the quadcopter 2 makes the elastic foot support 3 constantly be compressed, and at this moment most of the ini...

Abstract

The invention discloses a quadrocopter vertical wall surface rapid takeoff and landing system and method based on electrostatic adsorption. The quadrocopter vertical wall surface rapid takeoff and landing system comprises a high voltage electrostatic generator, two groups of elastic foot bionic structures and electrostatic adsorption electrodes, wherein the high voltage electrostatic generator ismounted on a quadrocopter; and the electrostatic adsorption electrodes is connected with the elastic foot bionic structures. The high voltage electrostatic generator generates high voltage to electriccharges of the electrostatic adsorption electrodes so as to provide an adsorption force for the quadrocopter during landing on the wall surface; through the elastic foot bionic structures designed bysimulating elastic legs of an insect, the dynamic potential energy during landing collision of the quadrocopter is converted into elastic potential energy to realize a buffering effect so as to prevent the quadrocopter from directly colliding with the wall surface to be damaged; and by using an inertial attitude sensor of the quadrocopter, a linear acceleration and an angular velocity in the landing collision process are detected in real time to trigger a corresponding landing strategy so that the quadrocopter rapidly and stably lands on the wall surface; and when the quadrocopter needs to take off from the wall surface, the high voltage electrostatic generator is stopped to eliminate the adsorption forces of the electrostatic adsorption electrodes to the wall surface, and the quadrocopter realizes taking-off.

Description

technical field [0001] The invention relates to the technical field of aircraft take-off and landing, in particular to a system and method for fast take-off and landing on a vertical wall of a four-axis aircraft based on electrostatic adsorption. Background technique [0002] The excellent maneuverability of UAVs makes it widely used in more and more fields, but the high power consumption leads to the shortcomings of UAVs such as insufficient battery life and limited flight distance, which makes it difficult to respond to the required distance or duration There will be some powerlessness for longer tasks, such as the need to hover for a long time to monitor the rescue scene after an earthquake or monitor the traffic flow at intersections, which has become a bottleneck for the development of drones. On the other hand, with the continuous development of society, plane space is becoming more and more precious, and the traditional take-off and landing method is that the drone ta...
