Abstract:
The present invention relates to an aircraft comprising a fuselage ( 1 ), a propulsion unit ( 7 ) at the rear tip of the fuselage and at least two engines ( 3, 5 ) each driving an engine shaft ( 32, 52 ), the propulsion unit including at least one propeller ( 71, 73 ) driven mechanically by the engine shafts ( 32, 52 ), characterised in that the propulsion unit ( 7 ) includes two propellers ( 71, 73 ), each of the propellers being driven by a propeller shaft ( 72, 74 ), the two propeller shafts being driven by the engine shafts ( 32, 52 ) via a first differential epicyclic gear train ( 40 ). Specifically, the input of the first differential gear train ( 40 ) is connected to the output of a second differential epicyclic gear train ( 60 ), the second differential gear train ( 60 ) including two inputs ( 61 c 2, 62 c 2 ), each of said two inputs being connected mechanically to one of said engine shafts ( 32, 52 ).

Claim (Index 1):
Aircraft comprising a fuselage, a propellant at the tail cone of the fuselage and at least two motors each driving a motor shaft, the propellant comprising at least one propeller driven mechanically by the motor shafts, characterised in that the propellant comprises two propellers, each of the propellers being driven by a propeller shaft, the two propeller shafts being driven by the motor shafts by means of a transmission mechanism comprising first and second differential epicyclic gear trains, the first differential epicyclic gear train comprising an input which is connected to the output of the second differential epicyclic gear train and the second differential gear train comprising two inputs, each of said two inputs being mechanically connected to one of said motor shafts.
