Tilting type vertical taking-off and landing unmanned aerial vehicle

Abstract

The invention relates to unmanned aerial vehicles, in particular to a tilting type vertical taking-off and landing unmanned aerial vehicle. The tilting type vertical taking-off and landing unmanned aerial vehicle comprises a task warehouse and a vehicle body. The task warehouse is integrally connected with the vehicle body. A flight control equipment cabin is arranged at the position, close to thetask warehouse, of the vehicle body. Wings are arranged on the positions, located on the left and right sides of the flight control equipment cabin, of the vehicle body. The two wings are symmetrically arranged. Auxiliary wings are arranged on the wings. Tail wings are arranged on the tail part of the vehicle body. Steering rudders are arranged at the tail wings. The two steering rudders are symmetrically arranged. Fixing wings are arranged at the positions, close to the vehicle body, of the wings. The unmanned aerial vehicle requires no external assistance to take off and land, and thereforeelectric power loss is reduced when the unmanned aerial vehicle is in the air. Resistance due to engine failure to tilt is reduced. A screw propeller is folded backwards after tilting of the tiltingengine by folding propellers, and therefore resistance caused by a conventional non-folding propeller is greatly reduced.

Or install 4 fixed electric motors on the tail boom, and then its working method is that the 4 additional motors are only responsible for the control of the take-off and landing of the aircraft, and these 4 motors do not participate in the control when the aircraft is cruising, and these 4 The two engines are generally vertically upward without aerodynamic rectification, which brings relatively large air resistance to the drone's cruise, thereby reducing the cruise time of the drone
