Abstract

A stator assembly 18 for a gas turbine engine is disclosed. The stator assembly includes an engine case 24 and a wall 26, such as a wall that includes an array of stator vanes 42. A high pressure region 74 (cooling chambers) extends between the wall and the engine case. The cooling chambers 74 are in flow communication through a leak path with a working medium flow path 14. An annular outer support 56 bounding the chambers beneath the vanes forms with the vanes an intermediate chamber 132 through which the leak path for cooling fluid passes. The annular support further includes a plurality of orifices 94 for diverting flow away from the leak path to lower the pressure of the intermediate chamber. In one embodiment, the chamber is formed in part by an annular groove 84 in the support and a plurality of flanges 124 associated with the vanes. The flanges are urged rearwardly into sealing contact with the annular support.
