Abstract: A flexible seal is used to seal between two adjacent gas turbine components. The flexible seal includes at least one metal ply having a forward end, an aft end axially separated from the forward end, and an intermediate portion between the forward end and the aft end. The intermediate portion defines a continuous curve in the circumferential direction, such that the aft end is circumferentially, and optionally radially, offset from the forward end. A plurality of relief cuts is defined through the at least one metal ply between the forward end and the aft end to increase flexibility and improve sealing in seal slots that are radially offset from one another.

Abstract: Various embodiments include gas turbine seals and methods of forming such seals. In some cases, a turbine includes: a first arcuate component adjacent to a second arcuate component, each arcuate component including a slot including one or more slot segments located in an end face and a seal assembly disposed in the slot. The seal assembly including a plurality of seal segments forming at least one T-junction where a first seal segment intersects a second seal segment and at least one shim seal. The plurality of seal segments define at least one chute gap. The at least one shim seal disposed in a slot proximate the at least one T-junction of the plurality of seal segments. The at least one shim seal positioned on a sidewall of the second seal segment and extending a partial length of the sidewall. The at least one shim seal seals the at least one chute gap to prevent a flow therethrough of a gas turbine hot gas path flow.
