Abstract
A stator seal land and supporting structure suitable for use in an axial flow rotary machine is disclosed. Included are concepts for matching the thermal response of the seal land to the rotor assembly and for inhibiting rolling or twisting of the seal land under changing thermal conditions. The seal land is free to expand and contract in diameter independently of the supporting stator structure.
