Abstract:
The invention relates to an aircraft comprising a fuselage ( 1 ), which is propelled by a turbine engine with two coaxial fans, namely an upstream fan ( 7 ) and a downstream fan ( 8 ), driven by two contra-rotating rotors ( 5, 6 ) of a power turbine ( 3 ). The two fans ( 7, 8 ) and the turbine ( 3 ) are integrated into a nacelle ( 14 ) which projects downstream from the fuselage ( 1 ) and through which air flows. According to the invention, at least one of the fans ( 7, 8 ) of the aircraft and, in particular, the downstream fan ( 8 ) comprises variable-spacing blades, and at least one stator-forming variable-spacing blade ring ( 25 ) in the aircraft is placed upstream of the upstream fan ( 7 ). The variable-spacing stator blades ( 25 ) and the variable-spacing blades of the downstream fan ( 8 ) are mutually configured to direct the air flow in a first mode in which the air flows through the nacelle ( 14 ) from upstream to downstream and in a second mode in which the air is pushed back upstream through the nacelle ( 14 ).

Claim (Index 2):
Aircraft according to  claim 1 , wherein a mechanism for rotating a pitch rod for the vanes of the downstream fan is installed in a central body, located downstream of the power turbine and surrounded by a primary flow passing through the turbine.
