Abstract
A perpendicular drive mechanism for a missile control actuation system employs an electric motor and power shaft operatively coupled to a first spur gear. A lead screw is coupled to a second spur gear. The lead screw is oriented parallel to the motor and perpendicular to a central longitudinal axis. The first and second spur gears meshingly engage such that the second spur gear rotates in the opposite direction as the first spur gear. A lead nut threadingly engages with and is configured to move linearly along the central axis of the lead screw. A crank arm is coupled on one end to the lead nut and on the other end to the canard shaft of a canard assembly. As the lead nut moves linearly along the central axis of the lead screw, the crank arm follows the lead nut and causes the canard assembly to actuate.
