Power-driven tilt three-rotor unmanned aerial vehicle

Abstract

The invention provides a power-driven tilt three-rotor unmanned aerial vehicle. The power-driven tilt three-rotator unmanned aerial vehicle has flight characteristics of both a helicopter and a fixed-wing aircraft and can take off and land in a vertical and short-distance way. The integral structure of the power-driven tilt three-rotor unmanned aerial vehicle is composed of all-moving canard wings, straight low wings and a fixed V tail. Two motors and rotors of the unmanned aerial vehicle are fixed at the wing tips of the canard wings and can independently tilt by certain angles along with the canard wings, and another motor and rotor of the unmanned aerial vehicle are installed in the V tail and can tilt by certain angles around a rotating shaft. When the rotating shafts of the thee rotors of the unmanned aerial vehicle tilt to a position near a Z axis, the unmanned aerial vehicle can fly like the helicopter; and when the thee rotors tilt to a position near an X axis, the unmanned aerial vehicle can fly like the fixed-wing aircraft. Through simultaneous control of the thrust and directions of the thee rotors, the reaction torque of the rotors is overcome and the posture of the unmanned aerial vehicle is controlled. The unmanned aerial vehicle provided by the invention can take off and land in a limited place or runway to execute special tasks and is improved in flight speed, duration of flight and payload.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a tilt-rotor unmanned aerial vehicle capable of vertical / short take-off and landing. Background technique [0002] At present, UAV technology has been widely used in our lives, such as aerial photography, inspection, investigation, entertainment and so on. The UAVs on the market are mainly divided into two categories: fixed-wing UAVs and rotary-wing UAVs. Most of the fixed-wing UAVs use the runway to take off and land, which has the advantages of large payload, fast cruise speed, long endurance and high efficiency, but it is highly dependent on the runway and cannot maneuver or hover in a small radius. , which limits its usage. Rotor-wing UAVs include ordinary helicopters and multi-rotor UAVs. They can take off and land vertically, and can fly in a smaller space. Their flexibility is higher than that of fixed-wing UAVs. However, their It has the disadvantages of small p...

Problems solved by technology

Most of the fixed-wing UAVs use the runway to take off and land, which has the advantages of large payload, fast cruise speed, long endurance and high efficiency, but it is highly dependent on the runway and cannot maneuver or hover in a small radius. , which limits its use

Rotor-wing UAVs include ordinary helicopters and multi-rotor UAVs. They can take off and land vertically, and can fly in a smaller space. Their flexibility is higher than that of fixed-wing UAVs. However, their There are disadvantages of small payload, slow cruising speed and short battery life

Therefore, both UAVs have their own advantages and disadvantages, which limit their flexibility and efficiency to a certain extent.
