ABSTRACT:
A gas turbine engine stator assembly includes an annular casing, a stator nozzle segment, and a shroud joined therewith. The nozzle segment includes an outer band having a forward hook joined to a complementary forward hook extending from the casing. The outer band also includes a plurality of circumferentially spaced apart stator lugs defining therebetween stator slots. The stator lugs are disposed between an aft flange and complementary lugs extending from the casing. Slots defined respectively between the stator and casing lugs are axially aligned for receiving axially extending lugs on the shroud for restraining rotation of the stator segment about the centerline axis of the casing.
