Abstract

FIELD: aeronautical engineering. SUBSTANCE: device has blade 1 with section elasticity axis 2. Vibration damping device is mounted on blades 1 with the aid of bracket 3. Mounted in bracket are autonomous shafts 4 and 5 which carry levers 6 and 7 with weights 8 and 9. Bracket is provided with stops 10 and 11 for limiting the angular motion of levers. EFFECT: reduction of loads on levers of pendulums, as well as loads on blades at non-functional frequencies and reduction of level of helicopter vibration. 2 dwg
