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.

Abstract: An angle of attack sensor includes a housing having an open end and a closed end, a faceplate positioned on the open end of the housing, the faceplate having an opening, a vane assembly extending through the opening of the faceplate, a vane shaft connected to the vane assembly and extending within the housing, the vane shaft having a bore extending through the vane shaft, a bearing surrounding the vane shaft, a vane shaft seal surrounding the vane shaft adjacent the bearing, and a first vent hole extending from an interior surface of the vane shaft to an exterior surface of the vane shaft between the bearing and a first end of the vane shaft seal, the first vent hole being in fluid communication with the bore of the vane shaft.
