Problems solved by technology

[0002] Although the flight speed of the aircraft is fast and the flight time is long, it cannot hover at a fixed point; although the multi-rotor aircraft can hover in the air, its flight time is short and the flight speed is slow.
Although there are currently some aircrafts that combine multi-rotor aircraft and aircraft, they all have certain defects. When flying in fixed-wing mode, the power of the multi-rotor part must be stopped, and this part becomes a burden on the aircraft. increase the burden on the aircraft

Abstract

A fort-axle vertical take-off and landing (VTOL) fixed-wing aircraft belongs to that technical field of aircraft, and comprises a fuselage, a wing, a tail wing, a left rotor thrust device, a right rotor thrust device, a tilting mechanism, a flight control device and a movable pin, wherein the four-axis vertical take-off and landing fixed-wing aircraft comprises a right rotor thrust device, a tilting mechanism, a flight control device and a movable pin. In VTOL and hover flight, left rotor thrust unit, the right rotor thrust unit is locked in the horizontal position, From hovering to fixed-wingflight, Unlock the left rotor thrust first, Horizontal position of the right rotor thrust device; the left rotor thrust device and the right rotor thrust device are locked after the left rotor thrustdevice and the right rotor thrust device are erected, and the flight attitude of the aircraft is controlled by controlling the aileron and the tail wing. The left rotor thrust device and the right rotor thrust device are locked after the left rotor thrust device and the right rotor thrust device are erected. The invention can perform vertical take-off and landing, the flight process is stable, the safety factor is high, and the invention is suitable for the work of logistics transportation, air fire extinguishing, post-disaster rescue and the like.

Description

technical field [0001] A four-axis vertical take-off and landing fixed-wing aircraft belongs to the technical field of aircraft, and in particular relates to a vertical take-off and landing fixed-wing aircraft. Background technique [0002] Although the flight speed of the aircraft is fast and the flight time is long, it cannot hover at a fixed point; although the multi-rotor aircraft can hover in the air, its flight time is short and the flight speed is slow. Although there are currently some aircrafts that combine multi-rotor aircraft and aircraft, they all have certain defects. When flying in fixed-wing mode, the power of the multi-rotor part must be stopped, and this part becomes a burden on the aircraft. Increased the burden on the aircraft. Contents of the invention [0003] In view of this, the present invention provides a four-axis vertical take-off and landing fixed-wing aircraft, which can perform vertical lift, hover in the air, and cruise for a long time and a...
