Disclosed is an aircraft windshield wiper system, having: a wiper arm; a reversible motor that drives the wiper arm, the motor including: a stator; a rotor configured to rotate relative to the stator; a forward shaft segment that is driven by the rotor and being rotationally connected to the wiper arm; an aft shaft segment that is driven by the rotor, the aft shaft segment including a forward end and an aft end; a ball nut that translates along the aft shaft segment from rotation of the aft shaft segment; a forward stop at a forward end of the aft shaft segment, configured to stop forward translational motion of the ball nut along the aft shaft segment; and an aft stop at an aft end of the aft shaft segment, configured to stop aft translational motion of the ball nut along the aft shaft segment.

Reversible motor configured with motion stops for aircraft windshield wiper system

An aircraft windshield wiper system includes a wiper blade with a composite support member and a blade element that interfaces with the windshield of the aircraft to clear the windshield of rain and other debris. The composite support member includes a wash tube integral with the composite support member, such that the wash tube receives windshield washing fluid from a fluid reservoir and dispenses the fluid onto the windshield of the aircraft. A plurality of clips can be used to couple the composite support member to the blade element.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The output shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across and clean the windshield. A sensor and a trigger are coupled to an actuator to ensure accurate sweep angle and parking position of the wiper arm and wiper blade.

A windshield wiper system (WWS) blade assembly is provided. The WWS blade assembly includes a composite frame and a blade that has a length which is normally shorter than a corresponding length of the composite frame. The blade includes first and second ends attachable to corresponding first and second ends of the composite frame, respectively.

Composite blade design

A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.
