Cooled blade of a turbomachine and method of cooling

摘要

The turbine blade has a coolant supply with a cover strip coolant channel (122) formed at least along one section of the cover strip element (114) and surrounding both the inlet opening (123) and the outlet opening (124). The inlet opening of the coolant channel opens into the first through flow channel (119a) and the outlet opening opens into the second through-flow channel (119b). Independent claim describes turbine stator with blade. Independent claim describes gas turbo assembly. Independent claim describes method for cooling cover strip element of gas turbine blade. Independent claim describes use of method to cool stator blade of gas turbo assembly. Independent claim describes method for manufacturing blade where top layer of blade head and closure webs are formed as one-piece cast unit.
