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 6):
Aircraft according to  claim 5 , wherein the planet gears of the second differential epicyclic gear train have a radial axis of rotation with respect to the axis of rotation of the planet carrier.
