  • Method of producing a turbine blade
    Patent number: 6739381
    Abstract: In a method of producing a turbine blade in hollow section, an especially low defect or scrap rate is to be ensured. To this end, a first core element is connected via a number of approximately cylindrical spacers to a further core element and/or to a casting mold, the cavities left in the casting mold by the core elements being filled by blade material, and the openings remaining in the turbine blade after the removal of the core elements and the spacers and produced by the spacers being closed by stopper elements.

  • Turbine blade and turbine
    Publication number: 20020157250
    Abstract: The present invention relates to a turbine blade, in particular for a gas turbine, having an airfoil profile and at least one platform for fastening to a primary component. According to the invention, each platform encloses an obtuse angle with a longitudinal axis of the airfoil profile. The design of the turbine blade as a single crystal is facilitated by this construction.
