TURBINE BLADE AND TURBINE WITH IMPROVED SEALING

摘要

PROBLEM TO BE SOLVED: To avoid high stresses in a blade trailing edge portion and assure safe and efficient cooling of the downstream end of a blade foot and of a rotor disk holding the blades.SOLUTION: The disclosure pertains to a turbine with a gas turbine blade 1 and a rotor heat shield 7 for separating a space region through which a hot working medium flows from a space region inside a rotor arrangement of the turbine. The rotor heat shield 7 includes an axial heat shield section 14 which is arranged substantially parallel to a surface of a rotor 6, and a radial heat shield section 15 at the upstream end of the axial heat shield section 14, which is extending away from a surface of the axial heat shield section 14 towards a hot gas.
