INTERNAL COOLING OF STATOR VANES

The invention is related to turbine stator (46) for gas turbine engines, including a stator vane (52), a first cooling passage (58) for providing a cooling fluid flow to a first portion of the stator (46), e.g., the leading edge (60), and a second cooling passage (62) for providing a cooling fluid f...

More Information
Summary:The invention is related to turbine stator (46) for gas turbine engines, including a stator vane (52), a first cooling passage (58) for providing a cooling fluid flow to a first portion of the stator (46), e.g., the leading edge (60), and a second cooling passage (62) for providing a cooling fluid flow to a second portion of the stator, e.g., the outer vane platform (54). A connection passage (70) extends at least partially through the stator (46) to connect an inlet (66) of the first cooling passage (58) to an inlet (64) of the second cooling passage (62). Thus, the cooling fluid flow is directed from a common cooling flow source (68) into the first cooling passage (58) and the second cooling passage (62) via the first cooling passage inlet (66). Thus, due to complex geometries, the cooling channels (58,62) may be machined separately improving manufacturability.
