  • Patent number: 9322286
    Abstract: A turbine nozzle for a turbomachine, the nozzle including two coaxial platforms interconnected by radial vanes, an inner platform being connected to an annular partition that is festooned or crenellated and on which there is fastened an annular support carrying elements made of abradable material. The support is capable of sliding circumferentially over the partition between a mounting-and-dismounting position and a position for locking the support on the partition.
    Type: Grant

  • Patent number: 9062553
    Abstract: A blade sector of a turbine distributor to be carried by a turbine casing of an aeronautical turbine engine, including a front connection mechanism and a rear connection mechanism, wherein the front connection mechanism is adapted so as to bear against a holder carried by the turbine casing. The sector further includes an anti-wear device formed by a piece of a metal material surrounding the front end of the front connection mechanism and provided between the front connection mechanism and the holder to ensure a sliding contact between the two parts. The anti-wear device is axially maintained in position on the blade sector using an attachment mechanism engaging with the front connection mechanism.

  • Patent number: 8397790
    Abstract: A method of manufacture of a wax model of an annular bladed turbomachine stator assembly includes in succession the positioning, in a mold, of a core intended to form the impression of a cavity of a blade of the assembly, the injection of a wax in the mold, and the removal of the wax model fitted with the core from the mold. The core is manufactured in metal and is positioned such that its radially internal end is housed in the portion of the mold defining the blade including the cavity, away from the radially internal end of this portion of the mold.
