  • Method of making a multi-vane model, tooling, and an assembly comprising a multi-vane model and a holder element
    Patent number: 10682685
    Abstract: A method of making a multi-vane model for a nozzle guide out of sacrificial material, includes the steps of fabricating a single-vane model out of sacrificial material, assembling at least two sacrificial material single-vane models with each other, and positioning (104, 108) a holder element on at least one sacrificial material single-vane model so as to hold a predetermined spacing between an inner platform and an outer platform. An assembly of a sacrificial material single-vane model for a nozzle guide together with a holder element, and also an assembly of a sacrificial material multi-vane model for a nozzle guide together with a holder element.

  • Shell mold for a sector of a 360°-set of guide vanes
    Patent number: 10449601
    Abstract: A shell mold for a guide vane sector includes a first platform and a second platform that are mutually coaxial and between which there extends at least one airfoil. The shell mold has a first platform molding portion suitable for forming the first platform, a second platform molding portion suitable for forming the second platform, an airfoil molding portion suitable for forming the airfoil, a fastener molding portion suitable for forming a fastener projecting from the first platform towards a first edge of the first platform, a main casting duct, a distribution duct connecting the main casting duct to the fastener molding portion, and an auxiliary duct connecting the main casting duct to the first platform molding portion beside said first edge.
