ABSTRACT:
A gas turbine of the type having high pressure air supplied to the cavity formed by the inner shrouds of the turbine vanes is provided with film cooling of the shrouds. A manifold supplies high pressure cooling air to portions of the gaps between inner shrouds not otherwise supplied and intermittent reliefs in the strip seal between shrouds regulates the leakage of this air, over the outer surfaces of the shrouds.
