A combined vertical take-off and landing aircraft

Abstract

The invention relates to a combined vertical take-off and landing aircraft, belonging to the technical field of aircraft, comprising a fuselage, a left wing, a right wing, a tail wing, a multi-rotor device, a support rod and a traction device; a fixing rod is arranged above the fuselage center of gravity position, and the left wing and the right wing are movably connected to the fixing rod througha bearing structure; at the lower end of the leading edge of the left wing and the right wing and the fuselage located below the left wing and the right wing root, the two springs are arranged in a V-shape. The lower end of the support rod is fixed above the fuselage of the aircraft at the center of gravity position, and the upper end of the support rod is connected to the frame at the center ofgravity position of the multi-rotor device through a bearing structure; Multi-rotor devices provide upward lift or forward pull to the aircraft. The multi-rotor unit is equipped with a flight controller. There are two tractors, one end of which is connected to the axle bracket of the multi-rotor unit and the other end is connected to the left or right wing above the leading edge. The invention cancarry out vertical take-off and landing; have long sailing time, stable flight process and high safety factor.

Description

technical field [0001] A combined vertical lift aircraft belongs to the technical field of aircraft, and in particular relates to a combined vertical lift aircraft. Background technique [0002] Although the fixed-wing aircraft has a fast flight speed and a long flight time, it cannot hover at a fixed point; although a 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 fixed-wing 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. Virtually increased the burden on the aircraft. Contents of the invention [0003] In view of this, the present invention provides a combined convertiplane, which can perform vertical lift, hover in the air, and cruise for a long time and a long distance.
