Abstract
A seal support assembly for a gas turbine engine includes a stator seal support having an annular seal backing extending axially away therefrom and having an integral retention flange at one end thereof. The retention flange includes a retention groove. An annular seal block is supported radially inwardly of the seal backing for cooperating with rotor seal teeth to define a fluid seal. A control ring is disposed radially outwardly of the seal backing and is supported thereby, with the control ring having a plurality of circumferentially spaced apart retention tabs cooperating with the retention flange for axially retaining the control ring on the seal backing. An annular heat shield is fixedly joined at one end to the seal support, and includes a plurality of circumferentially spaced apart retention tabs cooperating with the retention flange for axially retaining the heat shield to the seal backing while permitting unrestrained differential radial movement therebetween.
