Abstract
An air cooled turbine stator vane with an impingement cooling insert secured within a hollow cavity, where seal slots are formed between the cavity and the insert in which a flexible seal is located, and where the cavity and the insert includes chordwise movement bumpers and sideways movement bumpers each having a gap to allow for relative movement of the insert within the cavity from thermals while maintaining a seal between the cavity and the insert. The flexible seal is an X-shaped seal having four contact surfaces with the seal slots so that a high relative movement can occur while still maintaining a tight seal. The insert includes a number of cross-over tubes connecting return air holes on the pressure side to impingement holes on the suction side of the insert.
