Abstract
A lead screw control actuation system. A system according to an embodiment includes a motor configured to rotate a lead screw that is configured to increase torque provided by the motor. The lead screw is coupled to a nut through a threaded opening such that rotation of the lead screw causes the nut to move along a longitudinal axis of the lead screw. The nut includes a slot oriented in a direction perpendicular to the direction of motion of the nut. The system further includes a lever arm including a pin at a first end of the lever arm, the pin configured to slide in the slot of the nut to cause the lever arm to rotate in response to the motion of the nut. A second end of the lever arm is coupled to a canard such that rotation of the lever arm causes the canard to rotate.
