Abstract:
An electromechanical actuator (EMA) is provided. The EMA may comprise a ball nut having an annular geometry centered about an axis. A dual ball screw may be disposed radially inward from the ball nut and configured to rotate about the axis. The dual ball screw may also be mechanically coupled to the ball nut. A ball screw may be disposed radially inward from the ball nut and configured to rotate about the axis. The ball screw may also be mechanically coupled to the dual ball screw.
