  • Patent number: 8215910
    Abstract: An aircraft turbomachine fan is disclosed. The fan includes a turbomachine inlet cone that has an exterior surface intended to be closely followed by a flow section of the turbomachine, and an annular balancing flange that rotates as one with a fan disk about an axis of rotation and is equipped with a plurality of weight-fixing holes. The fan also includes one or more balancing weights mounted fixedly on the annular balancing flange. The annular balancing flange is positioned inside the inlet cone in such a way that its weight-fixing holes are isolated from the flow section. The flange is produced as a single piece with a fan blade retaining ring.

  • Patent number: 8162616
    Abstract: A turbomachine fan including blades and inter-blade platforms having radial flanges fastened to flanges of a rotor disk by threaded rods inserted into bushes mounted in orifices in the flanges of the platforms is disclosed. Each bush includes at least one deformable part interposed transversely between the threaded rod and an edge of the orifice in which the bush is mounted. The deformable part is intended to allow the platform to pivot in the event of an impact of a blade against the platform and to absorb some of the energy of the impact.
