## Abstract

A drone with a horizontal rotor includes one or more rotor(s) (115, 116) which rotate in a horizontal plane, each rotor (115, 116) being equipped with one or more rigid or non-rigid blades (120, 121), the blade end being mounted on an electric motor (110, 111) with a propeller.

## Claims

### Claim 1

A drone comprising: one or more first rotors which rotate in a horizontal plane, each first rotor comprising one or more rigid or non-rigid first rotor blades; a first end of each of said first rotor blades being mounted on a hub and a second end of each of said first rotor blades comprises a second rotor which rotates in a vertical plan, said second rotor comprising one or more propeller blades.

### Claim 2 (depends on 1)

The drone as claimed in claim 1, in which the blade end is equipped with a wing.

### Claim 3 (depends on 1)

The drone as claimed in claim 1, which comprises telescopic means that make it possible to adapt the radius of rotation of each said first rotor blades.

### Claim 4 (depends on 1)

The drone as claimed in claim 1, in which each of the first rotors (115, 116) is equipped with a winding, unwinding device in order to vary a radius of rotation of each first rotor blade which is linked thereto.

### Claim 5 (depends on 4)

The drone as claimed in claim 4, in which the winding, unwinding device is in a hub.

### Claim 6 (depends on 1)

The drone as claimed in claim 1, in which the propellers rotate in a reverse direction to the first rotor blade end vortex.

### Claim 7 (depends on 1)

The drone as claimed in claim 1, in which the motors are permanent magnet motors.

### Claim 8 (depends on 1)

The drone as claimed in claim 1, comprising a single first rotor and an electronic device for cyclically varying an aerodynamic parameter of said first rotor, and further comprising at least one sensor to ensure stability of the drone.

### Claim 9 (depends on 1)

The drone as claimed in claim 1, comprising two or more first rotors and a device for controlling a speed of rotation of said two or more first rotors so as to assure stability on an axis under the effect of an incident wind wherein stability on another axis is assured by a horizontal empennage.

### Claim 10 (depends on 1)

The drone as claimed in claim 1, connected by a cable to a wind turbine, said wind turbine comprising at least one turbine blade linked by a connecting means to a support structure, said wind turbine further comprising a generator (50) fixed to at least one of said turbine blades, said connecting means linked to the support structure by a hub and wherein each blade rotates in a vertical plane about the hub according to wind speed.

### Claim 11

A drone comprising a first rotor with at least one first rotor blade rotating in a horizontal plane about said first rotor, said at least one first rotor blade comprising at least one second rotor rotationally connected to a propeller, said propeller being driven by an electric motor wherein said second rotor and said propeller are mounted at a free end of said at least one rotor blade.

### Claim 12 (depends on 11)

The drone as claimed in claim 11, further comprising another first rotor with at least one first rotor blade wherein said first rotor blade comprises a connecting means.

### Claim 13 (depends on 12)

The drone as claimed in claim 12, wherein said connecting means is a telescopic connecting means.

### Claim 14 (depends on 13)

The drone as claimed in claim 13, wherein said telescopic connecting means comprise at least one connecting cable and a device for winding and unwinding said at least one connecting cable in order to vary a distance from said first rotor blade to an axis of rotation.

### Claim 15 (depends on 14)

The drone as claimed in claim 14, further comprising a hub housing said device for winding and unwinding the connecting cable.

### Claim 16 (depends on 11)

The drone as claimed in claim 11, wherein the propeller is driven in a reverse direction to a direction of rotation of a vortex generated at the free end of the first rotor blade.

### Claim 17 (depends on 11)

The drone as claimed in claim 11, wherein the electric motor is a permanent magnet motor.

### Claim 18 (depends on 11)

The drone as claimed in claim 11, comprising a single first rotor and an electronic device for cyclically varying an aerodynamic parameter of said first rotor, and further comprising at least one sensor to ensure stability of the drone.

### Claim 19 (depends on 11)

The drone as claimed in claim 11, comprising several first rotors and a device for controlling a speed of rotation of said first rotors to assure stability.
