Abstract: Disclosed is an aircraft having motors operable to actuate an aircraft windshield wiper (108) and an aircraft control surface (106). The aircraft includes a distributed control system (120) having digital storage and integrated with redundant processors. The aircraft includes controller instructions stored on the digital storage operable upon execution to operate a control surface motor of the motors to actuate the control surface to impact an orientation of the aircraft and operate a windshield wiper motor of the motors to actuate the windshield wipers.

Abstract: A windshield wiper system includes a three-phase motor (14), the three-phase inverter (34), a brake circuit (36), and a controller (18). The controller transmits commutation signals to the three-phase inverter to drive the motor according to an inboard-to-outboard speed profile and to drive the motor according to an outboard-to-inboard speed profile. The controller activates the brake circuit based on the inboard-to outboard speed profile, or the outboard-to-inboard speed profile, and a direct current bus voltage.

Abstract: An aircraft windshield wiper control system (30) includes an aircraft weather radar system (22) mounted in an aircraft (10) and that detects precipitation in a travel path of an aircraft (10) and an integrated avionics module (24) that receives aircraft weather information from the aircraft weather radar system (22). The system (30) also includes an aircraft wiper blade motor (50), a wiper blade motor drive and a wiper control module (26) that receives aircraft weather information from the integrated avionics module (24) and generates a wiper control signal, based on the received information that controls operation of the wiper blade motor drive to cause motion of the aircraft wiper blade motor (50).
