Claim Text:
1. A turbine engine stator vane that rotates about an axis, comprising: an airfoil extending axially between a first airfoil end and a second airfoil end, and comprising a concave side surface, a convex side surface and a cavity, wherein the concave and the convex side surfaces extend between an airfoil leading edge and an airfoil trailing edge, and the cavity extends axially into the airfoil from a cavity inlet in an end surface at the second airfoil end; a flange connected to the second airfoil end, wherein the flange extends circumferentially around at least a portion of the cavity inlet, and radially away from the concave and the convex side surfaces to a distal flange edge, wherein the flange has a non-circular cross-sectional geometry which lies in a plane that is perpendicular to the axis of the stator vane; and a shaft extending along the axis, and connected to the second airfoil end.
