The invention concerns an aircraft propelled by a turbine engine having contrarotating fans (7, 8). The turbine engine is incorporated at the rear of a fuselage (1) of the aircraft, and in the extension part of the fuselage, comprises at least two gas generators (2a, 2b) that supply, via a shared central stream (4), a power turbine (3). The turbine (3) comprises two contrarotating rotors (5, 6) for driving two fans (7,8) disposed downstream from the gas generators (2a, 2b). The aircraft comprises a means (15) arranged for separating the gas flow in the power turbine (3) into at least two concentric streams (16, 17) and a device comprising a first means for distributing the gas flow (21-24) between said streams (16, 17) from the central stream (4), and a first distribution means is configured to be able to open or close the supply of at least one so-called sealable stream (16) of the streams (16, 17) of the power turbine (3).
