METHOD OF CONTROL OF MAIN ROTOR OF FLYING VEHICLE AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: aviation; control of main rotor of rotorcraft. SUBSTANCE: proposed method includes deflection of blades by means of servoflaps deflected by means of wobble plate; wobble plate ring is placed in plane parallel to plane of propeller hub; this displacement is transmitted through burnishing rollers by ropes on servoflaps. Device proposed for realization of this method includes non-revolving ring supported by lever articulated on longitudinal control crank and levers secured on lateral control crank, roller burnished over ring through bearing secured on collective pitch crank which is secured in main rotor hub and is supported by slide block for change of collective pitch. EFFECT: enhanced rigidity and reliability; reduced mass; enhanced controllability. 3 cl, 2 dwg
