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.
