Hybrid flying device

Flying device having a main body on which a first combustion engine and a first electric motor are fixed, said first combustion engine and electric motor being arranged to create thrust vectors in one and the same thrust direction and being placed on either side of the main body in order to create thrust vectors on each side of a separation plane passing through a centre of gravity of said body so as to control the attitude of the flying device, characterized in that it has:

• a first electric generator mechanically coupled to the first combustion engine in order to be driven by the latter;
• and
• a first electrical energy transfer circuit connected between the first electric generator and the first electric motor, the first energy transfer circuit being configured to create a mechanical resistance that slows down the first combustion engine and to produce electrical energy in order to power the first electric motor,
• wherein the first transfer circuit has a first energy converter controlled to apply a load impedance to the first generator and to provide the energy recovered by the load impedance on an output to the first electric motor, and
• wherein the first transfer circuit has a second energy converter having an energy input connected to the energy output of the first energy converter and to the first electric motor, said second converter converting the energy received at its input into control signals of the first electric motor.
