The report presents a description of the research investigation on a fly-by-wire control system applied to a B-47 test aircraft. The investigation is primarily confined to the pitch axis of the test aircraft and is divided into three phases. Phase I system operation is based on using an electrical non-redundant primary flight control system with control inputs being generated by the normal control motion. Phase II system operation is based upon adding a side stick controller, pitch rate and nose acceleration feedback, and electrical roll axis control to the Phase I system. Phase III incorporates a 4 channel redundant actuator with hydraulic logic into the Phase II system. Flight test of the Phase I system was completed with over 40 flight hours, including touch and go landings being accumulated on the fly-by-wire system by four different test pilots.
