Abstract:

A gas turbine engine generally includes a compressor, a combustor, and a turbine. The turbine can include an integrated manifold comprising a plenum defined by a manifold disposed in connection with a divider plate and opposite a shielding plate comprising a plurality of apertures. The integrated manifold also includes a means for integrally mounting the manifold to the turbine. During operation of the gas turbine engine, a quantity of working fluid enters the integrated manifold and circulates throughout the plenum and shielding plate, and enters the turbine through the apertures to actively control clearances between turbine engine components.

Abstract:

A stator assembly for a rotary machine having an array of wall segments for bounding a working medium flow path is disclosed. Various construction details which provide a sealing structure for the segments are developed. In one detailed embodiment, a removable seal retainer for a seal chamber bounded by wall segments traps a resilient seal member in the seal chamber. In one particular embodiment, a modular subassembly for the engine is an outer air assembly disposed in a fixture as the subassembly is assembled.
