Active clearance control system for gas turbine engines

摘要

A gas turbine engine (10) generally includes a compressor, a combustor, and a turbine (12). The turbine (12) can include an integrated manifold comprising a plenum (16) defined by a manifold (18) disposed in connection with a divider plate (20) and opposite a shielding plate (22) comprising a plurality of apertures (24). The integrated manifold also includes a means for integrally mounting the manifold to the turbine (12). During operation of the gas turbine engine (10), a quantity of working fluid enters the integrated manifold and circulates throughout the plenum (16) and shielding plate (22), and enters the turbine (12) through the apertures (24) to actively control clearances between turbine engine components.
