Vibration attenuating suspension system for rotary-wing aircraft rotors

摘要

A suspension system is disclosed for reducing vibration between the rotor and the structure of a rotary-wing aircraft having a reduction-gear train coextensive with the shaft of the lift rotor. The housing of said gear train is supported by tie-rods and by a flexible beam having its mid- point attached to said housing and its extremities attached to the aircraft structure through the medium of flexible blocks. The beam may be made of metal or a composite material.
