Abstract

The turbine blade has an internal space through which a coolant fluid is guided and in which stiffening ribs are formed to reinforce and support the external walls. Coolant screens that reduce the cooling of the stiffening ribs, are arranged in front of the stiffening ribs in order to reduce thermal stresses. The turbine blade is preferably a gas turbine blade.
