Abstract: The present disclosure relates generally to a variable area turbine vane row assembly. In an embodiment, the variable area turbine vane row assembly includes rotatable vanes that are circumferentially biased and/or axially biased with respect to adjacent fixed vanes. In another embodiment, the variable area turbine vane row assembly includes multiple rotatable vanes positioned between adjacent fixed vanes, which may optionally be circumferentially biased and/or axially biased with respect to each other as well as to the adjacent fixed vanes.

Abstract: An airfoil array is disclosed. The airfoil array may include an endwall, and a plurality of airfoils radially projecting from the endwall. Each airfoil may have a first side and an opposite second side extending axially in chord between a leading edge and a trailing edge. The airfoils may be circumferentially spaced apart on the endwall thereby defining a plurality of flow passages between adjacent airfoils. The airfoil array may further include a convex profiled region extending from the endwall near the leading edge of at least one of said plurality of airfoils, and a concave profiled region in the endwall near a middle of at least one of said plurality of flow passages.

Abstract: An assembly is provided for rotational equipment. This assembly includes a plurality of seal shoes, a seal base and a plurality of spring elements. The seal shoes are arranged about a centerline in an annular array. The seal shoes include a first seal shoe configured with an aperture that extends radially through the first seal shoe. The seal base circumscribes the annular array of seal shoes. The spring elements include a first spring element. The first spring element includes a first mount, a second mount and a spring beam. The first mount is connected to the first seal shoe. The second mount is connected to the seal base. The spring beam extends laterally between and is connected to the first mount and the second mount.
