Abstract
A hot gas turbine wheel shroud ring, for hot gas turbine engines, is adapted to be concentrically positioned around the periphery of a row of buckets or blades on the circumference of a turbine wheel to provide a predetermined small sealing and running clearance between the tips of the turbine blades and the ring. The shroud ring is characterized as incorporating certain opposite warping or deflection characteristics from those found in shroud rings under normal high temperature operating conditions.
