An aircraft

Abstract

The invention relates to an 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 bar, an upper telescopic bar, a left telescopic bar and a right telescopic bar. The fuselage is provided with a fixed rod, and the left wing and the right wing are movably connected to the fixed rod through a bearing structure. 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 of gravity position of the multi-rotor device through a bearing structure; the multi-rotor devices provide upward lift or forward pull to the aircraft; one end of the telescopic rod is connected to the support rod and the other end is connected to the multi-rotor device; a left telescopic rod and a right telescopic rod are symmetrically arranged, one end of which is connected with a support rod, and the other end of which is correspondingly connected with an upper wing surface of the airfoil and is close to a leading edge. The angle of attack of the left wing and the right wing is changed by the telescopic movement of the left and right telescopic rods. The invention can carry out vertical take-off and landing, has long sailing time, stable flight process and high safety factor.

Description

technical field [0001] An aircraft belongs to the field of aircraft technology, and in particular relates to an 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 an aircraft capable of vertical lifting, hovering in the air, and long-time, long-distance cruise. [0004] An aircraft, comprising a fuselage, a left wing, a right wing, an empennage, a multi-rotor device, a supp...

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. Invisibly increases the burden on the aircraft
