1. A turbine shroud support comprising:
- an annular mounting flange having a radially outer end fixedly mountable to a casing, and a radially inner end;
an annular hanger spaced radially inwardly from said mounting flange for supporting a turbine shroud;
an annular coupling fixedly joining said mounting flange to said hanger, and including a plurality of circumferentially spaced apertures defining a plurality of beams therebetween, said beams being sized and configured for reducing axial force and axial moment transmitted from said mounting flange to said hanger for attenuating radial distortion transmitted to said hanger from said mounting flange.

Abstract
A shroud support for a gas turbine engine includes a mounting flange mountable to a casing, a hanger for supporting a turbine shroud, and an annular coupling joining the mounting flange to the hanger. The coupling includes a set of circumferentially spaced apertures defining a set of beams therebetween, with the beams being sized and configured for attenuating radial distortion from the mounting flange transmitted to the hanger. In a preferred embodiment of the invention, the coupling includes a frustum which includes the apertures and beams.
