Abstract
A windshield wiper system for use on an aircraft includes a controller and a wiper assembly including a wiper arm, a wiper blade, and a moving block. Further, the windshield wiper system includes a rail assembly including a rail assembly rack, a plurality of electromagnets, and an electrical interface. The electrical interface and the plurality of electromagnets induce a force on the moving block of the wiper assembly, causing the wiper assembly to sweep across the windshield of the aircraft. The controller is coupled to the rail assembly and the controller is configured to direct the motion of the wiper assembly through command signals to the rail assembly.
