ROTORCRAFT Russian patent published in 2011 - IPC B64C11/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to rotors and flight control systems. Rotorcraft incorporates, in compliance with first version, two rotors with opposite rotation of blades. Pair of aligned rotors feature independently-variable angles of attack and rotational speeds and are fitted on moving part of tail boom articulated with main part of tail boom by hinge with two-rotation axles to allow pushers propellers to run to the left and right, up and down relative to tail boom proper. Rotorcraft incorporates, in compliance with second version, two rotors with opposite rotation of blades. Pair of aligned rotors feature independently-variable angles of attack and rotational speeds and are fitted on moving part of tail boom articulated with main part of tail boom by hinge. The only axle of said hinge is secured at an angle to main part of tail boom and at an angle to moving part so that rotational axis of moving rotors may describe a cone with vertex located at hinge assembly and, in one position, parallel to flight vehicle lengthwise axis.

EFFECT: improved maneuverability of flight vehicle.
