Abstract: A windshield wiper system for an aircraft includes a wiper arm (12) and a wiper shaft (14) with a first end (34) connected to a base of the wiper arm. An electric motor (20) is coupled to the wiper shaft to rotationally drive the wiper shaft. The windshield wiper system also includes a brake system (24). The brake system includes an electromagnet (38) comprising an energized mode and a de-energized mode. The brake system also includes an anti-rotation assembly with a first element and a second element. The first element is connected directly to the wiper shaft. The second element is rotationally stationary relative the wiper shaft and the first element. The second element is configured to interlock with the first element to prevent rotation of the first element and the wiper shaft when both the electromagnet is in the de-energized mode and the wiper arm is in a park position.
