Turbine blade and method of manufacture for the same

摘要

The aim of the invention is to produce a turbine blade (1), comprising an outer wall (4), surrounding a hollow cavity, through which a cooling fluid (6) flows and which has an increased life expectancy, even under heavy loading and is simple to produce. The aim of the invention is achieved, whereby the thickness (8) of the outer wall (4), at least over an extent of the blade leading-edge region (7), is such that, at least in pre-determined areas of the external wall (4), pre-determined temperature thresholds (TM) and/or pre-determined temperature gradients ( DELTA TM) are not exceeded.
