<p>A fan rotor, in particular for a turbo engine. The invention concerns a fan rotor for a turbo engine comprising a disk (1) carrying blades, a substantially frustoconical cover (20) mounted on the disk (1), and means for axially retaining the blades comprising a ring (11) mounted in an annular groove (5) of the disk (1) and forming a support for the blade roots. The ring (11) is scalloped or crenellated and engages with a scalloped annular radial rim (7) of the disk (1). The rotor also comprises at least one axial tooth (16) inserted into hollow portions of the rim (7) of the disk (1) and of the ring (11). Two coaxial parts (37, 38) disposed radially inside the disk (1) respectively comprise first and second attachment flanges (39, 40) for attachment to the disk (1), interposed axially between the cone (20) and the disk (1), circumferentially offset from each other, and secured independently of one another to the disk (1).</p> |
