  • Patent number: 9784114
    Abstract: A rotating assembly for a turbomachine, including a disc having an external periphery with alternating recesses and teeth, blades extending radially from the disc and the feet of which are axially engaged and radially retained in the recesses of the disc, platforms extending on the circumference from the blades and being arranged end to end on the circumference, with respect to each other, axial sealing device upstream and/or downstream of an annular zone extending radially from the platforms up to the disc. The sealing device radially includes an internal annular portion and an external annular portion structurally distinct from each other, and the external annular portion of which is elastically constrained radially inwards by the internal annular portion.

  • Patent number: 9650895
    Abstract: A turbine wheel including a plurality of blades having roots engaged axially and held radially in slots in a disk alternating between teeth of the disk, in which the blades have platforms arranged circumferentially end to end and each connected to a blade root by a tang, is provided. Separator walls extend from the tangs in a circumferential direction and from upstream to downstream so as to define radially between the platforms and the teeth of the disk at least a radially inner cavity and a radially outer cavity between two adjacent tangs.

  • Publication number: 20140356172
    Abstract: The invention relates to a turbine wheel (104) comprising a plurality of blades having roots engaged axially and held radially in slots (34) in a disk (22) alternating between teeth (36) of the disk (22), the blades having platforms (100) arranged circumferentially end to end and each connected to a blade root (26) by a tang (102). According to the invention, separator walls (90) extend from the tangs (102) in a circumferential direction and from upstream to downstream so as to define radially between the platforms (100) and the teeth (36) of the disk at least a radially inner cavity (92) and a radially outer cavity (94) between two adjacent tangs.
