Abstract: A stator vane includes an airfoil having an airfoil shape. The airfoil shape having has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII, Table VIII, Table IX, Table X, Table XI, or Table XII. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.

Abstract: An actively morphable vane includes a leading edge, a trailing edge downstream of the leading edge, a tip end, a hub end spaced radially outward from the tip end, a pressure side comprising a pressure surface, and a suction side comprising a suction surface. The pressure surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The suction side is positioned opposite of the pressure side and the suction surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The actively morphable stator vane also includes an actuator in mechanical communication with the tip end. The actuator is operable to selectively morph the actively morphable stator vane between a first configuration and a second configuration. The first configuration is optimized for a first operating condition, and the second configuration is optimized for a second operating condition.
