1. An apparatus to reduce deflection of an airfoil, the apparatus comprising:
a plate including an aperture, the airfoil disposed in the aperture; and
a damper operatively coupled between the plate and a hub of the airfoil, the airfoil separate from the hub, the damper to transform flexural deflection of the airfoil to radial deflection of the plate.
