Abstract: A manned/unmanned aerial vehicle adapted for vertical takeoff and landing using the same set of engines for takeoff and landing as well as for forward flight. An aerial vehicle which is adapted to takeoff with the wings in a vertical as opposed to horizontal flight attitude which takes off in this vertical attitude and then transitions to a horizontal flight path. An aerial vehicle system which has removable wing sections which allow for re-configuration with different wing section types, allowing for configurations adapted for a particular flight profile. A method of customizing a configuration of an unmanned aerial vehicle based upon flight profile factors such as duration, stability, and maneuverability.

Abstract: A flying machine disclosed in the present application includes a main body, a flying module and a function module which is for controlling working state of the flying module. The flying module includes at least one pair of flying units, wherein the flying unit includes a flying frame, rotors and a steering oar which works with the rotors to propel the flying machine. Compared with the conventional flying machine which requires four rotors, while loaded with the same power source, the present flying machine doubles the flight time, which solve the problem of short working time.

Abstract: A method for dynamically converting the attitude of a rotary-wing drone that includes a body including an electronic board controlling the piloting of the drone and four link arms forming lift-producing wings, each arm including a rigidly connected propulsion unit. The method includes executing, on reception of an instruction allowing a conversion between flight using the rotary wings and flight using the lift of the wings, the conversion being defined by a pitch angle to be achieved θref, of a repeated sequence of steps until the pitch angle θref is achieved, including estimating the current pitch angle θest of the drone, determining an angular trajectory depending on the pitch angle to be achieved θref, and sending one or more differentiated commands based upon the angular trajectory and the current estimated pitch angle θest to one or more propulsion units such that the drone is rotated about the pitch axis.

Abstract: Methods, systems and apparatus, including computer programs encoded on computer storage media for unmanned aerial vehicle beyond visual line of sight (BVLOS) flight operations. In an embodiment, a flight planning system of an unmanned aerial vehicle (UAV) can identify handoff zones along a UAV flight corridor for transferring control of the UAV between ground control stations. The start of the handoff zones can be determined prior to a flight or while the UAV is in flight. For handoff zones determined prior to flight, the flight planning system can identify suitable locations to place a ground control station (GCS). The handoff zone can be based on a threshold visual line of sight range between a controlling GCS and the UAV. For determining handoff zones while in flight, the UAV can monitor RF signals from each GCS participating in the handoff to determine the start of a handoff period.

Abstract: A light unmanned vertical take-off aircraft includes at least two fixed coplanar propulsion devices and at least one wing providing the lift for the drone. The coplanar propulsion devices and the wing are each laid out on the frame of the drone so that the plane of the profile chord line of the wing is substantially parallel to the plane defined by the two coplanar propulsion devices. The wing is pivotingly mobile relative to the frame along an axis parallel to the pitch axis of the drone. Also a method is provided for controlling orientation of a wing of a light unmanned vertical take-off aircraft as described here above. The method includes controlling an orientation of a wing as a function of at least one flight parameter of the aircraft.
