ABSTRACT:
Turbine blades having heat localization segments, especially for use in gas turbines, are disclosed. The segments are provided with covering elements in the form of thin cover plates that are supported against the blade root. The segments are formed as one piece together with both the actual blade and with reinforcing elements. The segments are used to impede access of a hot working medium to the turbine rotor.
