Abstract
Official abstract text for this publication.
The present invention relates to a turbine blade of a gas turbine with an airfoil arranged on a blade root and having at least one cooling air duct running in the longitudinal direction of the turbine blade, arranged inside the turbine blade and extending through the blade root, characterized in that at least one swirl-generating element is arranged in the transitional area between blade root and airfoil in the cooling air duct, with the swirl-generating element including an outer ring and several swirl-generating stator vanes arranged thereon, which are connected to a centric area, as well as to a method for its manufacture.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a turbine blade, comprising the steps of: casting the turbine blade, the turbine blade including: a blade root; an airfoil arranged on the blade root; a cooling air duct running in a longitudinal direction of the turbine blade positioned inside and extending through the blade root and the airfoil; providing a swirl-generating element manufactured as a separate component from the turbine blade from the step of casting the t…
