FIELD: rotary-wing flying vehicles. SUBSTANCE: rotor has hub 1 fitted on drive shaft 2, blades 3 with swivel panels 4 containing aerodynamic balances 6 operated by control ring 7 of wobble plate for cyclic setting of angle (sweep) of swivel panels 4 during revolution of rotor by means of rods 8 and 10 of lever 10 and for horizontal flight due to shift of disk area and obtaining additional horizontal thrust in direction of flight by means of aerodynamic balances. EFFECT: elimination of vibration of helicopter case in flight due to cyclic change of blade angle; increased horizontal speed. |
