ABSTRACT:
The clearance between a seal assembly 48 and a turbine wheel 16 in an engine of the type having a radial outflow compressor 24 and a radial inflow turbine 16 is minimized by forming the seal assembly 48 in part out of a plurality of segments 74 disposed in a circular array and which are relatively movable but sealed to each other. The thermal stress in the segments 74 will be less than in a single ring resulting in an extended life before the onset of cracking and eventual mechanical failure.
