Unmanned aerial vehicle with four-shaft cone power structural layout

Abstract

The invention relates to an unmanned aerial vehicle with a four-shaft cone power structural layout and belongs to the technical field of spacecraft design. The unmanned aerial vehicle with the four-shaft cone power structural layout adopts a four-shaft cone radial power mechanism layout design. An unmanned aerial vehicle body comprises four frames with the same length; the four frames are connected to the same point and distributed in a radial shape; connecting lines between four external side vertexes of the four frames form a pyramid-shaped regular tetrahedron; and the connecting lines of any three external side vertexes form a regular triangle. The flight attitude of the unmanned aerial vehicle can be flexibly adjusted through coordination between the unmanned aerial vehicle and a sensor; and the unmanned aerial vehicle easily realizes flying actions such as horizontal movement, vertical movement, steering and turnover in the air. If a single power system of the unmanned aerial vehicle is damaged during the flight period, a control system of the unmanned aerial vehicle can dynamically adjust the remaining three power systems according to sensor data so as to guarantee the attitude balance of the unmanned aerial vehicle in the air.

Description

technical field

[0001] The invention relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle with a four-axis cone power structure layout, and belongs to the technical field of aviation aircraft design. Background technique

[0002] Traditional unmanned aerial vehicles, such as common four-axis, six-axis, eight-axis and other unmanned rotors (or use micro-jet power systems), mainly provide power through the rotor system distributed on the same horizontal plane around the body during flight. Attitude adjustment is performed by controlling the rotor speed.

[0003] Limited by the traditional physical structure layout design, the flight attitude adjustment of this type of aircraft is not stable and flexible enough, and it is easily affected by factors such as strong winds. extreme case. And the normal flight of the traditional rotorcraft depends on the normal work of all the rotors. When the rotors are damaged, the flight activities will not be carr...
