TURBINE BLADE

摘要

A turbine vane for a rotary turbomachine is described having a turbine blade which is delimited by a concave pressure-side wall and a convex suction-side wall which are connected in the region of a vane front edge which can be assigned to the turbine blade and enclose a cavity which extends in the longitudinal extent of the vane front edge and is delimited on the inner wall by the pressure-side wall and the suction-side wall in the region of the vane front edge and by an intermediate wall which extends in the longitudinal direction to the vane front edge and connects the suction-side wall and the pressure-side wall on the inner wall. The disclosed vane is distinguished by the fact that the intermediate wall has a perforation at least in sections in the connecting region to the suction-side wall and/or pressure-side wall, in order to increase the elasticity of the intermediate wall.

1. A turbine blade for a rotating turbomachine; the turbine blade comprising:
having a blade airfoil which is bounded by a concave pressure side wall and a convex suction side wall which are connected in the region of a blade leading edge which can be assigned to the blade airfoil, and which enclose a cavity which extends in the longitudinal extent of the blade leading edge and is delimited internally by the pressure side wall and suction side wall in the region of the blade leading edge and by an intermediate wall which extends in the longitudinal direction to the blade leading edge and connects the suction side wall and pressure side wall internally, wherein the intermediate wall has, at least in sections, a perforation in a connection region to the suction side wall and/or pressure side wall in order to increase the elasticity of the intermediate wall in the connection region.
