Vertical take-off and landing aircraft based on variable rotor-wing technology and dual rotor-wing layout

A vertical take-off and landing aircraft based on variable rotor-wing technology and dual rotor-wing layout, comprising dual blade variable rotor-wings, a dual rotor-wing system, a lifting fuselage, a wing-fuselage connecting mechanism, a forward flying propulsion device, a central power system, and a take-off and landing auxiliary device;

• wherein
• the aircraft uses a design of variable configuration to achieve vertical take-off and landing and high-speed level flight, simultaneously;
• a main aerodynamic wing surface adopts a design of dual blade variable rotor-wing, which is a core component for the aircraft to generate lift and switch configurations, and can be switched between a rotor wing configuration and a fixed wing configuration with variation of a forward flight speed, and aerodynamic efficiency in entire flight envelope is greatly improved by introducing the dual blade variable rotor-wing technology and the dual rotor-wing layout;
• aerodynamic shape of the lifting fuselage and the wing-fuselage connecting mechanism are in coordinated linkage with the rotor-wing configuration, which may maintain stable level flight of the aircraft when the configurations is switching, and risk and difficulty in the switching process are reduced;
• the aircraft uses a propulsion device at a rear portion to provide forward thrust, and a central power system provide energy for the forward flying propulsion device and the dual rotor-wing system, which improves overall efficiency of the entire aircraft.
