Uncoupled seal support assembly

A gas turbine engine seal support assembly comprising:

• a stator seal support;
• an annular seal backing extending axially away from said seal support and having an integral retention flange at one end thereof, said retention flange having a radially outwardly facing retention groove;
• an annular seal block supported radially inwardly of said seal backing for defining with rotor seal teeth positionable adjacent thereto a seal for restricting fluid flow therebetween;
• a control ring disposed radially outwardly of said seal backing and supported thereby, said control ring having at one end thereof a plurality of radially inwardly extending and circumferentially spaced apart retention tabs cooperating with said retention flange for axially retaining said control ring on said seal backing;
• and
• an annular heat shield fixedly joined at one end to said seal support, and having at a radially inner end a plurality of radially inwardly extending and circumferentially spaced apart retention tabs cooperating with said retention flange for axially retaining said heat shield to said seal backing while permitting unrestrained differential radial movement therebetween.
