Patent ID: 8701415

Claim:
A turbine system, comprising: a transition duct comprising an inlet, an outlet, and a passage extending between the inlet and the outlet and defining a longitudinal axis, a radial axis, and a tangential axis, the outlet of the transition duct offset from the inlet along the longitudinal axis and the tangential axis, the transition duct further comprising an interface member for interfacing with a turbine section; a flexible metallic seal contacting the interface member to provide a seal between the interface member and the turbine section, the seal comprising a plurality of layers, at least one of the plurality of layers in contact with the turbine section and at least one other of the plurality of layers in contact with the interface member, wherein one of the plurality of layers is a seal plate, at least a portion of the seal plate having a curvilinear cross-sectional profile; and wherein at least a portion of the seal has a contour that generally corresponds to and maintains a contour of a contact surface of the turbine section in an operating condition.
