Abstract:
An aircraft comprising a fuselage and propelled by a turbine engine having two coaxial and contrarotating fans, the turbine engine comprising a power turbine having two contrarotating rotors, one of which drives a fan upstream from the turbine, the other a fan downstream from the turbine, each fan comprising a ring of blades, and the assembly of the fans and the power turbine being incorporated at the rear of the fuselage, in the extension of same. The aircraft comprises, for at least one of the fans, a device for blocking the rotation of the fan and a device configured to modify the pitch of the blades of the fan in such a way as to make it operate as a flow straightener with respect to the other fan.

Claim (Index 1):
An aircraft comprising:\n a fuselage having a rear; a turbine engine having first and second coaxial and contra-rotating fans, the turbine engine also having a power turbine having two contra-rotating rotors, one rotor driving the first fan upstream of the power turbine, the other rotor driving the second fan downstream of the power turbine, each first and second fan having a ring of blades, wherein the assembly of the first and second fans and the power turbine being integrated at the rear of the fuselage, in the extension thereof, wherein for at least one fan of the first and second fans, a locking device for locking the rotation of the at least one fan, means designed to modify the pitch of the blades of said at least one fan so as to operate said fan as a guide vane assembly in relation to the other fan of the first and second fans, the locking device having braking means which make it possible to rigidly connect the rotor of the power turbine driving the corresponding at least one fan to an immovable casing of the turbine engine.
