    摘要: A turbine blade comprises an external pressure side plate comprising a plurality of external pressure ribs, an internal pressure side plate comprising a plurality of internal pressure ribs, and a plurality of pressure flow redirection areas. The external pressure side plate is disposed over the internal pressure side plate to form a pressure side double wall. The external pressure ribs are disposed at a first angle with respect to a blade span reference line and the internal pressure ribs are disposed at a second angle with respect to the blade span reference line to form the pressure flow redirection areas. The pressure side double wall is configured to pass a coolant through the pressure side double wall. A fabrication method aligns the external pressure side plate and the internal pressure side plate to form the pressure flow redirection areas between the external pressure side plate and the internal pressure side plate.

    摘要: A coolable double walled structure, for use and exposure in a hot gas flow environment, includes a jet issuing wall, a target wall spaced from the jet issuing wall defining at least one cavity therebetween. The jet issuing wall includes at least one impingement rail having a greater thickness than the jet issuing wall such that a bottom portion of the impingement rail extends within the cavity formed between the jet issuing wall and the target wall. A number of impingement ports are disposed within each impingement rail to provide flow communication through the jet issuing wall to the target wall. Due to the relatively thick dimensions of the impingement rail, the impingement ports disposed within respective impingement rails can be directionalized so as to provide for local cooling needs. In one embodiment, the entry areas of the impingement ports are bell shaped so as to lower inlet pressure loss. In another embodiment, the exit area immediately surrounding the impingement ports is rounded for lower post-impingement pressure drop.

    摘要: A component is disclosed. The component includes a substrate comprising an outer surface and an inner surface. The inner surface defines at least one hollow, interior space, and the outer surface defines one or more grooves that extend at least partially along the outer substrate surface and have a respective base. One or more access holes are formed through the base of a respective groove, to connect the groove in fluid communication with the respective hollow interior space. The component further includes a coating comprising one or more layers disposed over at least a portion of the outer substrate surface. The groove(s) and the coating together define one or more channels for cooling the component. One or more trenches are formed through one or more coating layers and at least partially define at least one exit region for the cooling channel(s).
