Abstract
A turbine shroud assembly is provided for use in conjunction with a turbine engine having a turbine rotor consisting of a disc and plurality of blades attached to and extending radially outwardly from the disc wherein the outer tips of the blades are axially tapered at a predetermined angle. The shroud assembly comprises an annular shroud positioned around the turbine blades and tapered axially at the predetermined angle such that the shroud is evenly spaced radially outwardly from the turbine blades. A plurality of circumferentially spaced bell crank assemblies attach the shroud to a turbine support housing and, in response to thermal expansion of the shroud, axially shift the shroud in a direction to decrease the clearance between the shroud and the turbine blade tips.
