GAS TURBINE COMPONENT

摘要

A gas turbine component, for forming part of a stage of the turbine, operable to change cooling scheme, includes an airfoil profiled section, a cooling passageway, film holes and interchangeable connectors. The profiled section includes pressure and suction sides joined together at chordally opposite leading and trailing edges. The cooling passageway extends between the pressure and suction sides along the leading edge to enabling cooling fluid to flow therefrom. The film holes are configured on the cooling passageway to enable the flow of a portion of the cooling fluid to a portion of the profiled section. The interchangeable connectors configured to the cooling passageway, one at a time, to change the cooling scheme. An insert may also be provided to close and open the film holes.

1. A gas turbine component for forming part of a stage of a gas turbine to be operable to change cooling scheme thereof, the gas turbine component comprising:
an airfoil profiled section having a pressure side and a suction side joined together at chordally opposite leading and trailing edges; at least one cooling passageway extending between the pressure side and the suction side along the leading edge, the at least one cooling passageway capable of enabling cooling fluid to flow therefrom; a plurality of film holes extending between the at least one cooling passageway and an exterior of the airfoil profiled section, the plurality of film holes capable of directing at least a portion of the cooling fluid from the at least one cooling passageway to flow over a portion of the airfoil profiled section; andinterchangeable connectors, configured to the at least one cooling passageway, one at a time, to change the cooling scheme by changing the flow of the cooling fluid in coordination with the opening and closing of the plurality of film holes
