An interface seal for a turbine engine including a rotor shroud hanger including at least one opening, an outer band including an aft rail, and a seal spring mounted in the opening and extending over an interface between the outer band and the shroud hanger, is described. The seal provides a barrier that prevents the leakage of high pressure cooling air through the interface into the combustion gas flowpath bypassing turbine engine components, and thus forces the high pressure cooling air through the necessary turbine engine components.

[ What is claimed is:] [19.] A method for sealing an interface between high pressure cooling air and combustion gases in a turbine nozzle, the interface including a high pressure nozzle including an outer band and an inner band, and a blade row including a rotor shroud attached to a hanger, the outer band further including an inside face, an outside face, and an aft rail having a first end, a second end, and a pad located between the first end and the second end, the hanger extends radially 360 degrees and includes a first slot and a second slot extending radially 360 degrees, the second slot includes a shoulder, said method comprising the steps of:attaching at least one pin to the aft rail of the outer band;inserting a seal spring into the second slot, wherein the first end of the seal spring is adjacent the shoulder; andconnecting the outer band to the hanger such that the outer band pad contacts the hanger between the hanger first and second slots.
