Title:
ROTOR CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2828621
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor control system capable if reducing noise and vibration of a helicopter by realizing a flap driving mechanism capable of effectively drawing out flap performance.
SOLUTION: A rotor control system is provided with a blade 10 attached to a main rotor shaft 1 so that the pitch angle may be changed, a flap 20 attached on the reargue side if the blade 10 so that the pitch angle mat be changed, a first link mechanism for controlling the pitch angle of the blade 10, and a second link mechanism for controlling the pitch angle of the flap 20. The first link mechanism includes a swath plate 14 composed of a rotational part 12 connected to the blade 10 by the link mechanism, and a control part 13 to be displaced according to the steering amount. The second link mechanism includes a swath plate 31 composed of a rotational part 29 connected to the flap 20 by the link mechanism, and a control part 31 to be displaced by actuators 36a, 36b, and a higher harmonic wave controller 37.
