TURBOMACHINE FAN ROTOR

The invention relates to a fan rotor (1) for a turbomachine. The fan rotor (1) comprises a fan disk (2), fan blades (3) with a leading edge (3a) and a trailing edge (3b), platforms (4) inserted between the blades (3) and fixed to the periphery of the disk (2), each comprising an aerodynamic surface (4a) extending from the leading edges (3a) to the trailing edges (3b) of the blades (3). The aerodynamic surface (4a) comprises an upstream longitudinal portion (40) at the side of the leading edges (3a) and a downstream longitudinal portion (41) at the side of the trailing edges (3b), the upstream longitudinal portion (40) is supported by a first member (5) of the platform (4) fixed to the disk (2) in a pivotable manner, and the downstream longitudinal portion (41) is independent of the upstream longitudinal portion and is supported by a second member (6) of the platform (4) which is independent of the first member (5) and fixed to the disk (2) in a pivotable manner. 本发明涉及用于涡轮机的风扇转子(1)，该风扇转子包括：风扇盘(2)；风扇叶片(3)，该风扇叶片
