TURBINE BLADE, METHOD FOR PRODUCING SAME AND METHOD FOR DETERMINING THE POSITION OF A CASTING CORE USED WHEN CASTING A TURBINE BLADE

摘要

A turbine blade has a blade geometry defined in a coordinate system and at least one cavity which is open to the outside and which has a blade internal surface. At least one planar detection surface, which is accessible for the measuring head of a coordinate measuring device, is formed in the blade internal surface, wherein the at least one planar detection surface is assigned a defined design position and/or a defined design orientation with respect to the coordinate system in which the blade geometry is defined.
