HOT GAS PATH COMPONENT TRAILING EDGE HAVING NEAR WALL COOLING FEATURES

A hot gas path component (38) includes a substrate (48) having an outer surface (50) and an inner surface (52). The inner surface defines an interior space (54). The outer surface defines a pressure side surface (58) and a suction side surface (60). The pressure and suction side surfaces are joined...

More Information
Summary:A hot gas path component (38) includes a substrate (48) having an outer surface (50) and an inner surface (52). The inner surface defines an interior space (54). The outer surface defines a pressure side surface (58) and a suction side surface (60). The pressure and suction side surfaces are joined together at a leading edge (36) and at a trailing edge (40). A first cooling passage (30) is formed in the suction side surface of the substrate. It is coupled in flow communication to the interior space. A second cooling passage (30), separate from the first cooling passage, is formed in the pressure side surface. The second cooling passage is coupled in flow communication to the interior space. A cover (68) is disposed over at least a portion of the first and second cooling passages. The interior space channels a cooling fluid to the first and second cooling passages, which channel the cooling fluid therethrough to remove heat from the component.
