Abstract
According to one aspect of the invention, a turbine assembly includes a first stationary component, a second stationary component positioned radially outside the first stationary component, a first key feature on the first stationary component configured to mate to a second key feature on the second stationary component and a seal assembly positioned between the first and second key features to reduce fluid flow between the first and second key features. The seal assembly includes a V-shape member and a second member adjacent to the V-shape member, the second member and V-shape member having different rates of thermal expansion. The seal assembly also includes a latch feature coupled to the V-shape member configured to expand the seal assembly from a compressed state to an expanded sealing state when the seal assembly is subject to an elevated temperature.
