ABSTRACT:
A continuous 360.degree. impingement baffle is attached directly to a shroud support structure such that the combination provides a low-leakage, high pressure plenum for supplying impingement airflow to the turbine rotor shroud for cooling purposes. After impingement, the air is at a low-pressure and is free to feed the conventional leakage paths with little loss of system efficiency.
