ABSTRACT:
A combinational actuator latch and crash stop apparatus and method are provided. In one embodiment, an air lock apparatus includes a wind vane portion adapted to have a wind force exerted thereon. The wind force is generated by a rotating disk. The combinational air lock and crash stop apparatus also includes an airlock latch portion coupled to the wind vane portion. The airlock latch portion is adapted to lock the actuator arm into a selected position. Specifically, the airlock latch portion is adapted to lock an actuator arm into a position such that the distal end of the actuator arm and a head attached to the distal end of the actuator arm will be locked at or near the inner diameter of the disk. The present combinational air lock and crash stop apparatus further includes a crash stop coupled to the airlock latch portion. The crash stop is adapted to restrict the rotation of the actuator arm such that the distal end of the actuator arm and the head are prevented from being moved outwardly beyond the outer diameter of the disk.
