The aircraft propulsive unit having on the one hand, a fixed central structure in the axis of which is housed a gas generator whose nozzle delivers a hot jet and, on the other hand, an upstream fan or blower concentric with the gas generator and rotating inside an annular channel defined by the fixed structure and by a peripheral cowling or fairing with double wall carried by the fixed structure, the blower providing the forced circulation of a cold flow in the channel for improving the performance of the power unit, the fairing being formed of two parts, the upstream one of which is fixed and surrounds the blower, whereas the downstream one is mobile and slides parallel to the axis x-x′of the generator, the propulsive power unit further having a system for reversing the thrust of the cold flow which is formed of pivoting doors having respectively external and internal walls which, in the retracted position of the doors, are aligned respectively with the external and internal walls of the fairing. The doors are housed in openings of the sliding part of the fairing, defined by annular parts joined together by beams, the doors pivoting about pivots housed in the beams and each door being coupled by at least one link to the fixed central structure so that the backward movement of the sliding part of the fairing causes rotation of the doors, which frees openings and closes the annular channel, the doors projecting radially outwardly of the fairing.

Aircraft propulsive power unit of the type comprising, on the one hand, a fixed central structure along the axis of which is housed a gas generator whose nozzle delivers a hot jet and, on the other hand, an upstream fan or blower concentric with the gas generator and rotating inside an annular channel defined by the fixed structure and by a peripheral cowling or fairing with double wall carried by the fixed structure, said blower providing the forced circulation of a cold flow in the channel for improving the performance of the power unit, the fairing being formed of two parts, the upstream one of which is fixed and surrounds the blower, whereas the downstream one is mobile and slides parallel to the longitudinal axis of the generator, said propulsive power unit further comprising a system for reversing the thrust of the cold flow which is formed of pivoting doors having respectively external and internal walls which, in the retracted position of the doors, are aligned respectively with the external and internal walls of the fairing, characterized in that said doors are housed in openings of the sliding part of the fairing, defined by annular parts joined together by beams, said doors pivoting about pivots housed in said beams and each door being coupled by at least one link to the fixed central structure so that the backward movement of the sliding part of the fairing causes rotation of the doors, which uncovers the openings and closes the annular channel, the doors projecting radially outwardly of the fairing.
