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 4):
Aircraft according to  claim 1 , wherein the pitch of the vanes of the downstream fan can be adjusted so that this fan pushes back the air upstream, the nacelle being equipped with means that allow the air to be discharged radially, between the upstream fan and the downstream fan.
