Control method and control system for balanced descent of aircraft

Abstract

The invention belongs to the technical field of aircraft control, and provides a control method and control system for balanced descent of an aircraft. The control method comprises the following steps that A, when the aircraft descends to a preset height distant from the ground, multiple beams of laser pulse microwaves are emitted to the ground; B, according to the time difference when the laser pulse microwaves are received after being reflected by the ground, the evenness of the ground is obtained; C, according to the evenness of the ground, the lengths of corresponding retractable hydraulic expandable rods are adjusted to make the aircraft land horizontally. Thus, the safe descent and repair of the aircraft are achieved on a complex and uneven terrain to make the aircraft land horizontally, and falling down or damage of the aircraft is avoided, so that the risks and losses are reduced to the minimized degree, and therefore the problems existing in current aircraft descent techniques are solved that because the terrain is not even, the aircraft cannot land in a balanced mode while descending on the ground, so that falling down or damage of the aircraft is caused.

Description

technical field [0001] The invention belongs to the technical field of aircraft control, and in particular relates to a control method and a control system for balanced landing of an aircraft. Background technique [0002] Existing aircraft, especially unmanned aerial vehicles (UAVs), are more and more widely used. Aircraft can collect data while running in the air, including disaster monitoring, traffic patrol, public security monitoring, etc., to provide users with important information. However, when the traditional aircraft lands, due to the unevenness of the terrain, the aircraft cannot land in a balanced manner when it lands on the ground, causing the aircraft to fall or be damaged. [0003] Therefore, the existing aircraft landing technology has the problem that the unevenness of the terrain makes it impossible for the aircraft to land in a balanced manner when it lands on the ground, causing the aircraft to fall or be damaged.
