Abstract

A HGP segment, such as a nozzle or shroud, for a GT system includes a body. A seal slot is defined in the face of side edge(s) of the body. Each seal slot has radial inner and outer walls, an inner sidewall between the radially inner and outer walls, and receives part of a sealing member extending between the seal slots of adjacent segments. Groove(s) are defined in one or both of the radial inner and outer walls of the seal slot and extend transverse to the slot. The groove(s) extend between the inner sidewall of the respective seal slot and the face of the respective side edge. A cooling passage is defined in the body and has an outlet defined in the inner sidewall within the at least one groove of the slot and an inlet in fluid communication with an inner coolant source defined in the body.
