- FIG. 1 shows an embodiment of an airborne device 10.
- the airborne device 10 comprises at least three wings, for example from three to eight wings 12.
- the airborne device comprises at least four wings 12.
- the airborne device 10 comprises an even number of wings 12.
- the wings 12 are interconnected by flexible cables.
- a flexible cable is a cable that, under the action of an external force, can deform, including bending, without breaking or tearing.
- each wing 12 is connected to each adjacent wing by a flexible cable 14 and is connected to the opposite wing by a flexible cable 16.
- each wing 12 is connected to a connecting device 18 by a flexible cable 20.
- the connecting device 18 is connected to an anchoring system, not shown, by a flexible cable 22.
- the anchoring system may be on the ground, on a buoy, or on a ship.
- the connecting device 18 comprises a first part 24 to which the cables 20 are fixed and connected to a second part 26 to which the cable 22 is fixed.
- the first part 24 is adapted to pivot relative to the second part 26 around the axis of the cable 22.

- Each wing 12 corresponds to a supporting wing comprising a lower surface 30 connected to an upper surface 32 by a leading edge 34, a trailing edge 36, an outer lateral edge 38 facing outwardly of the device 10, and a lateral edge 40 inside, oriented towards the inside of the device 10.
- Each wing 12 may correspond to a profiled wing, for example according to a NACA profile.
- the cables 14 and 16 are connected substantially to the same point of the inner side edge 40.
- the cable 20 is connected to the wing 12 at a point on the underside 30 away from the leading edge 34, the trailing edge, the outer side edge 38 and the inner side edge 40.
- the cable 20 may be connected to the inner side edge 40.
- the wings 12 of the airborne device 10 rotate in the manner of the blades of a wind turbine on the ground.
- the present embodiment is based on the fact that, for a conventional wind turbine on the ground, the parts of the blades, which in operation are the most effective for capturing the kinetic energy of the wind, are located near the free ends of the blades, there where the driving torque due to the wind is the highest.
- the wings 12 are therefore located in the useful areas where the driving torque due to the wind 42 is the largest and the cables 14, 16, 20 are located in the areas where the wind-driven driving torque 42 is reduced. Therefore, the surface described by the wings 12 during their movement can be important while the airborne device has a simple structure and a reduced mass.
- the maximum operating diameter of the airborne device 10 is between 20 m and 200 m, preferably between 100 m and 150 m.
- the weight of the airborne device 10, not counting the cable 22, can be between 20 kg and 20 tons.
- the rotational speed in operation of the wings can be between 1.5 and 200 revolutions per minute.

- each wing 12 may comprise an electric generator comprising a turbine driven during the movement of the wing 12. The electrical energy produced can then be transmitted to the ground by the cables 20 and 22.
- FIG 3 shows an embodiment of a transport system 47 in which the cable 22 of the airborne device 10 is connected to a vehicle 48, in this example a ship. The airborne device 10 is then used as traction means of the vehicle 48.
- the longitudinal axis D of the wing is called an axis perpendicular to the two most distant parallel planes, one of which is tangential to the outer lateral edge 38 and the other tangential to the inner lateral edge 40.
- the wingspan E of the wing 12 is the distance between these planes.
- the span E is between 5 m and 50 m, preferably between 25 m and 35 m.
- the wing rope 12, measured in a plane perpendicular to the longitudinal axis D, is not constant along the axis D.
- the rope increases from the inner side edge 40 to a maximum chord and then decreases to the outer side edge 38.
- the maximum chord is between 0.25 m and 5 m, preferably between 1.25 m and 3.5 m.
- a leading edge arrow, F 1 is the angle between the axis D and a plane tangent to the leading edge 34.
- the arrow is positive when the angle, oriented from the axis D to the tangent plane , is counter-clockwise when looking at the extrados of the wing and negative in the opposite case.
- the arrow of the leading edge F 1 varies along the axis D of the inner lateral edge 40 to the outer lateral edge 38.
- the arrow of the leading edge F 1 is successively, by moving away from the inner lateral edge 40 along the negative axis D and decreasing in absolute value as one moves away from the inner lateral edge 40 along the axis
- the leading edge arrow 34 is between - 20 degrees and 5 degrees, and 60% of the span from the inner side edge 40, the leading edge arrow 34 is between 0 degrees and 10 degrees.
- the trailing edge arrow, Fp is the angle between a plane tangent to the trailing edge and the axis D. According to one embodiment, the trailing edge arrow Fp varies along the axis D of the edge. lateral side 40 to the outer lateral edge 38.
- Wing 12 includes:
- actuators 53, 54, 55, 56 each actuator 53, 54, 55, 56 being controlled by the control module 50 and being connected to one of the cables 14, 16, 20;
- the battery 60 may be replaced by an electric generator.
- the electrical power for supplying the control module 50, the motors 54 for actuating the cables 14, 16, 20 and the actuating motors for the fins 57, 58 can be brought to each wing via the cables 20 and 22.
- Each actuator 53, 54, 55, 56 is adapted to modify the length of the stretched portion of the cable 14, 16 or 20 outside the wing 12.
- each actuator 53, 54, 55, 56 is adapted to unroll or wind the cable 14, 16, 20 to which it is connected. The length of the portion of each cable 14, 16 extending between two flanges 12 and the length of the portion of each cable 20 extending between a flange 12 and the connecting device 18 can thus be modified.
- Figures 5 and 6 show another embodiment of the wing 12 wherein the wing 12 further comprises two fins 62 which may each comprise a movable flap 64.
- the first fin 62 projects projecting from the extrados 32 and the second drift 62 is projected from the underside 30.
- the actuation of the movable flap 64 of each fin 62 is controlled by the control module 50.
- the actuation of the movable flap 64 allows in particular to control the lateral position of the airborne device 10 with respect to the wind 42.
- FIG. 7 represents an embodiment of the wing 12 in which the propulsion system of the wing comprises a motorized propeller 70 which projects from the leading edge 34 of the wing towards the front of the wing in the direction of rotation of the wing 12 in operation.
- the motorized propeller 70 can be controlled by the control module 50 or can be remotely controlled from a ground station.
- An advantage of the use of a motorized propeller is that it allows, in addition, to move the center of gravity of the wing 12 forward in the direction of rotation of the wing 12 in operation. This may be advantageous for improving the stability of the wing.
- the propeller 70 can be removable and folded, at least in part, in the wing 12 when it is not used.
- the propulsion system may comprise a jet engine, including a rocket engine or a propulsion system with compressed air.
- Each wing 12 may further comprise a landing gear, not shown, which allows the movement of the wing 12 to the ground.
- the landing gear can be removable so as to be folded, at least in part, into the wing 12 when not in use.
- FIG. 8 shows an embodiment in which each cable 14, 16, 20 or 22 or at least one of the cables 14, 16, 20 or 22 has a profiled section including a leading edge 72 and a trailing edge 74 thinned. This allows in particular to reduce the drag of the cable.
- FIG. 9 shows an embodiment in which each cable 14, 16, 20 or 22 or at least one of the cables 14, 16 or 30 further comprises a core 76 contained in a profiled envelope 78.
- the core 76 may be in a first material and the envelope 78 may be in a second material, the density of the first material being greater than the density of the second material. This allows to bring the center of gravity of the cable towards the leading edge and thus improve the aerodynamic stability of the cable.
- the airborne device 10 can both comprise a propulsion system, such as the propeller 70 shown in FIG. 7, cables 14, 16, 20 shaped as shown in FIGS. 8 and 9, and a train of landing.
- a propulsion system such as the propeller 70 shown in FIG. 7, cables 14, 16, 20 shaped as shown in FIGS. 8 and 9, and a train of landing.
