ABSTRACT:
The mounting of low expansion full ring shrouds in a turbine engine requires radial compliance to limit the stresses experienced by the shroud due to thermal growth differences between the shroud and its support. A method provides radial compliance with no looseness in a mounting system. The mounting system also allows for axial motion of the shroud, should such motion be needed or desired. The lack of looseness in the mounting system results in an ability to achieve smaller tip clearances and thus better engine performance.
