Abstract

The invention relates to the technical field of aircrafts, and concretely relates to a single-layer four-rotor aircraft. The aircraft comprises a rack, a power device is arranged on the rack, flying devices are arranged at the front end and the rear end of the rack respectively, each flying device comprises a supporting rod, a U-shaped connecting rod and flying units arranged at the two ends of the U-shaped connecting rod, and the supporting rods are fixed to the rack. The center of the U-shaped connecting rod is hinged to the supporting rod, each flight unit comprises a steering engine, a rotating bearing and rotor wings symmetrically arranged on the two sides of the rotating bearing, the rotating bearings are fixed to the ends of the U-shaped connecting rod through the steering engines,and the power device is connected to the U-shaped connecting rod and can drive the U-shaped connecting rod to move up and down. The power device drives the U-shaped connecting rod to move up and downso as to drive the flight units at the two ends of the U-shaped connecting rod to move up and down, the rotor wings can rotate around the rotating bearings in the circumferential direction, the rotating speed becomes higher and higher, when a certain rotating speed is reached, lift force can be generated, the vertical take-off effect of the aircraft is achieved, the structure is simple and compact, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a single-layer quadrotor aircraft. Background technique [0002] The lift device of an aircraft is a device based on aerodynamics. According to the structure, it can be divided into fixed wings and rotors. Fixed wing aircraft generally have a fuselage and symmetrically arranged fixed wings, which are powered by propellers to obtain greater flight speeds. and mobility. Its flight principle is that there is a relative speed between the fixed wing and the air, and the interaction between the air and the various surfaces of the fixed wing generates lift so that the aircraft obtains flight capability. The disadvantage of fixed-wing aircraft is that it cannot hover in the air, and needs to taxi on the runway to take off or land and the support of airport facilities. A rotorcraft such as a helicopter is characterized in that it does not need a runway when it takes off and can hover i...
