Abstract
A coolable shroud having a sealing surface surrounding the tips of the turbine blades of a gas turbine engine is disclosed. The shroud comprises a plurality of arcuate segments which are supported by the turbine case in end to end relationship concentrically about the axis of the engine. Each segment is adapted to receive and distribute cooling air about the walls of the shroud which are exposed to the hot working medium gases flowing through the turbine during operation of the engine. Cooling air is flowable to the gap between adjacent shroud segments to maintain continuity of the sealing surface across the gap.
