Abstract
A stator assembly 20 for a gas turbine engine is disclosed. The stator assembly includes an outer case 22 and an array of stator vanes 32 extending inwardly across an annular flow path 18 for working medium gases. The stator assembly includes a duct 34 which engages the stator vanes and which is trapped between a stator vane and a stator element 38 extending inwardly from the outer case. The duct includes a transition piece 78 which extends axially to shield a portion of the stator vane. In one embodiment the duct includes an extension 80 which extends into proximity with an outer air seal assembly 31 to form a cooling air chamber 36 adjacent to the stator element.
