FIELD: transport.
SUBSTANCE: proposed rotorcraft comprises two coaxial rotors and two pushing coaxial propellers arranged on tail boom. Rotors feature opposite sign of rotation while rotor blade pitch varies differentially for every rotor independently. Pushing propellers feature opposite sign of rotation. Cyclic pitch of every said propeller may be varied by swash plates setting blade angle of attach from positive to negative magnitudes while total pitch of said propellers varies differentially for every rotor independently.
EFFECT: control by pushing propellers.
