Structure and working method of a tiltrotor unmanned aerial vehicle

Abstract

The invention discloses a tiltrotor unmanned aerial vehicle structure and its working method. By setting the duct roller on the outer ring of the turbine cover and being able to rotate relative to the turbine cover, the axis of the duct roller and the axis of the transmission shaft of the tilting mechanism Parallel; directly connected to the turbine cover through the transmission shaft of the tilting mechanism, and a fan blade power mechanism for providing power is provided in the turbine cover. At the same time, the ducted rollers are set on the outer ring of the turbine cover, and the turbine cover and the ducted rollers form a circular protection for the fan blade power mechanism at the same time. The shaft rotates to adjust the direction of the turbine cover, thereby adjusting the overall power output direction of the smart drone. The flight of this model realizes multifunctional use.

Description

technical field [0001] The invention belongs to the technical field of vector tilting unmanned aerial vehicles, and particularly relates to a tilting rotor unmanned aerial vehicle structure and a working method thereof. Background technique [0002] The unmanned aircraft operated by radio remote control equipment and self-provided program control device, that is, the development of UAV technology, has no cockpit on board, but is equipped with autopilot, program control device and other equipment. The personnel on the ground, on the ship or in the remote control station of the mother machine use radar and other equipment to track, locate, remote control, telemetry and digital transmission. It can take off like a normal plane under radio control or launch with a booster rocket. When recovered, it can be automatically landed in the same way as the landing process of ordinary aircraft, or it can be recovered by remote control with parachute or block; it can be used repeatedly. ...

Problems solved by technology

[0003] With the rapid expansion of the application field of UAVs, the load of UAVs and the multi-purpose of UAVs are getting higher and higher. By setting up multi-rotors on the aircraft, the lift of the aircraft will be significantly improved under the premise that the weight of the aircraft does not increase much. , has the advantages of strong load capacity, high controllability, flexible movement, and good fault tolerance. However, the rotors of multi-rotor UAVs are currently installed in a fixed way, and the direction adjustment ability of the generated lift vector is limited, and only vertical take-off and landing can be achieved. And the ability to fly in the air mainly depends on the rotation speed of different rotor blades of the UAV to adjust the direction of the UAV. It is vulnerable to environmental influences such as wind and unstable during the work process. Moreover, UAVs are now mainly used for aerial flight surveys work, unable to meet the requirements of working close to the surface of the building
