DEVICE FOR DAMPENING VIBRATIONS OF HELICOPTER MAIN ROTOR BLADES Russian patent published in 1997 - IPC

Abstract RU 2078008 C1

FIELD: dampening vibrations of helicopter main rotor blades. SUBSTANCE: device is made in form of mechanical pendulums located on either side of each blade. Pendulums are made in form of levers with weights at their ends which are mounted in brackets on blade root at axis located at angle relative to blade chord to ensure reliable dampening of vibrations acting perpendicularly and longitudinally relative to chord. EFFECT: enhanced reliability. 4 dwg
