Abstract: The application discloses a vertical take-off and landing aircraft based on variable rotor-wing technology and dual rotor-wing layout. A main aerodynamic surface adopts the design of dual blade variable rotor-wings, and may be switched between a rotor wing and a fixed wing configuration along with variation of flight speed; based on variable rotor-wing technology and dual rotor-wing layout, power requirements for a power system are greatly reduced while vertical take-off and landing and high-speed level flight are realized; meanwhile, through coordinated linkage with the fuselage and actuating mechanism devices, better flight efficiency and maneuverability are obtained in the entire flight envelope. The aircraft has good hover and low-speed performance, but has certain requirements for apron parking facilities, so it is more suitable for use in fixed sites with limited space or carried on low-speed vehicles to complete various aviation tasks such as atmospheric detection.
