Abstract
A flap actuator system for an airfoil structure including a flap member for controlling the airfoil structure; a bearing member interconnected with the flap member and airfoil structure; and an electromagnetic motor segment integral with the flap member and airfoil structure for rotating the flap member about the axis of the bearing member relative to the airfoil structure and including a field circuit integral with one of the flap member and airfoil structure and an armature circuit integral with the other; the bearing member may be a tension member which is attached to the airfoil structure at a first point and to the flap member at a second point spaced from the first point.
