Method for wind harvesting and wind rejection in flying drones

The present invention concerns a method of manoeuvring a vertical take-off and landing, unmanned aerial drone (100) comprising at least an aerodynamic surface (101), wherein, during a flight of the drone, the aerodynamic surface generates lift and/or drag and an aerodynamic surface area is dynamically varied to compensate for adverse wind currents and/or to use said wind currents and/or to use an effective airspeed velocity as an assistance in manoeuvring the drone flight, said aerodynamic surface area variations allowing to reduce an energy consumption of the drone.
