摘要
56,938 A gas turbine stationary vane is provided having cooling air inserts and an impingement plate attached to the outer shroud of the vane. The inserts extend only a short distance above their mounting surface on the outer shroud so that there is adequate access for properly welding the inserts to the outer shroud. Insert extensions are disposed in the end of each insert so as to form cooling air inlets which project above the impingement plate. The insert extensions are installed after the insert has been welded to the outer shroud so as to not interfere with access to the weld area. The insert extensions are attached to the inserts and the impingement plate by flexible seal collars, allowing the collars to form positive seals between the components.
