  • Foundry core assembly for manufacturing a turbomachine blade, associated method of manufacturing a blade and associated blade
    Patent number: 9890644
    Abstract: A foundry core for manufacturing a blade of a turbomachine including a tip section offset, including a core element for forming various internal cavities, the core element including a leading-edge cavity internal core, central cavity internal cores, and a trailing-edge cavity internal core. The internal core for the central cavity adjacent to the internal core for the trailing-edge cavity includes a bulge extending toward the core for the leading-edge cavity.
    Type: Grant
    Filed: February 12, 2013
    Date of Patent: February 13, 2018
    Assignee: SNECMA
    Inventors: Huu-Thanh Tran, Michael Hansom, Christian Bariaud, Patrice Eneau
  • Inter-blade sealing for a turbine or compressor wheel of a turbine engine
    Patent number: 9410433
    Abstract: An inter-blade sealing for a turbine or compressor wheel of a turbine engine includes inserts engaged in longitudinal cavities in side edges of platforms of blades and bearing, in operation, against facing side edges of platforms of adjacent blades. Each insert has a cylindrical elongate shape and includes in its outer cylindrical surface at least one annular groove for passing platform cooling air.

  • OPTIMISATION OF THE BEARING POINTS OF THE STILTS OF VANES IN A METHOD FOR MACHINING SAID VANES
    Publication number: 20140369844
    Abstract: A method of machining a blade in a three-dimensional machining center, the blade including an airfoil, a platform including upstream and downstream supports formed respectively under the upstream and downstream portions thereof for supporting a sealing liner, a blade root, and a stilt interposed between the platform and the blade root, the method including the upstream and downstream supports constituting two bearing points for a six-point positioning system for positioning the blade in the three-dimensional machining center.
