    摘要： Quad-redundant signal processors in a flight control computer control valves to modulate airflow in a circulation control rotor system. The valves are arranged in a series and each valve is responsive to two signal processors. Loss of a valve occurs when both signal processors for that valve fail. A first valve, and every fourth valve in the series thereafter is responsive to a first signal processor and a third signal processor. The next valve in the series, and every fourth valve in the series thereafter is responsive to a second signal processor and a fourth signal processor. The third valve in the series, and every fourth valve in the series thereafter is responsive to the first signal processor and the fourth signal processor. The next valve in the series, and every fourth valve in the series thereafter is responsive to the second signal processor and the third signal processor. Predetermined pairs of adjacent valves define fixed rotor locations and the pair of valves at a fixed rotor location are controlled each by two and aggregately by all four signal processors. The first and second processors are in a separate chassis from the third and fourth processors.

    摘要： A control system for rotary wing aircraft having a circulation controlled tor is provided. Two axial flow air compressors driven from the engine input shaft provide an air flow which is ducted to the rotor blades through a bifurcated duct and a non-rotating air plenum and released through spanwise slots in the blades. Damping is accomplished by a conically shaped diverter valve in the air plenum and a butterfly valve adjacent the air compressors. Aircraft stability is achieved through a gyro coupled to the rotor shaft which integrates pilot controlled input with rotor cyclic flap moment input.

    摘要： A helicopter having the usual tiltable, vertical thrust and lift producing rotor, a separate forward thrust producing propeller as well as provisions for yaw control and compensation is improved in that the propeller is constructed as unshrouded propulsion device. A pair of flow deflecting rudders is arranged downstream from the propeller and symmetrically to both sides of the craft; a frame on the tail portion of the craft includes vertical shafts for pivotally mounting the rudders. A T shaped support structure in the frame includes regular elevational, horizontally extending stabilizer fins and carrier arms. An elevator is arranged upstream from the propeller and from one of the elevational stabilizer fins. The elevator reaches laterally beyond and longitudinally alongside the one fin or beyond a circle provided by the propeller.

    摘要： The present invention provides a single seat aircraft having the capabilities of vertical takeoff, landing and hovering operations utilizing the X-Wing as a conventional helicopter rotating wing. After transition to forward flight following takeoff, the rotating wing is stopped and becomes a fixed wing of "X" configuration. The aircraft utilizes two engines within the fuselage, one engine being positioned vertically above the other along the longitudinal axis of the aircraft, the particular arrangement of engines allowing aircraft size and weight to be substantially reduced.
