Abstract
A sealing arrangement includes a transition duct having an aft frame that circumferentially surrounds the downstream end of the transition duct. The aft frame defines a cooling circuit that has an outlet configured to direct cooling air in a radial direction. A first stage nozzle is spaced apart from the aft frame and defines a gap therebetween. A sealing assembly that extend circumferentially along at least a portion of the aft frame and is coupled to the aft frame. The sealing assembly includes a flexible sealing element that extends from the aft frame, across the gap, to the first stage nozzle. The flexible sealing element is forced into sealing engagement with the first stage nozzle by pressure from a compressed working fluid. A cooling flow director that is disposed between the outlet of the cooling circuit and the flexible sealing element.
