ABSTRACT:
An air seal assembly 10 for a gas turbine engine comprising a full ring cover plate 20 and seal segment 14 attached to impingement boxes 18. The impingement boxes have counter mounted hooks 24, 26 that interlock with a turbine flange 22 and cover plate 20 to secure the seal assembly 10. Holes 36 in the impingement boxes 18 direct cooling air to the entire backside 38 of seal 14. Seals 14 are mounted to the impingement boxes 18 by pedestals 40 that are positioned to enhance seal flexibility since axial edges are unrestrained.
