A dual channel actuator for regulating control surfaces of an aircraft such as a helicopter. Primary and secondary channels are coupled by a differential gear. An internal stop in the differential gear limits the short term range of travel or authority of the primary channel. The secondary channel allows extended long term authority by recentering the reference point about which the rotational range of the primary channel is determined. A servo motor and primary input gear of the differential gear comprise the primary channel. A second servo motor and se...
An aircraft control system having a dual channel actuator for regulating control surfaces of the aircraft, said actuator comprising: a primary motor; means coupling said primary motor with said control surfaces, wherein activation of said primary motor drives said coupling means and allows regulation of said control surfaces; means coupled with said coupling means for limiting movement of said coupling means in response to activation of said primary motor, said movement being limited to a preselected range about a reference point; and means coupled with ...
