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 4):
Aircraft according  claim 1 , wherein the axis of rotation of the input of the first differential epicyclic gear train is coaxial with the axis of rotation of the output of the second differential epicyclic gear train.
