ABSTRACT:
A stator assembly for a gas turbine engine having a support structure and a stiffening ring 46 extending about the support structure 34 is disclosed. Various construction details which increase the rigidity of the support structure and enable the stiffening ring to accept axial and radial loads are developed. In one embodiment the stiffening ring 46 is the seal ring 52 for a seal end 74. In one particular embodiment, the thermal expansion characteristic of the support structure is greater than the thermal expansion characteristic of the stiffening ring to insure that the stiffening ring is in tension under normal operative conditions of the engine.
