ABSTRACT:
A hybrid fluid and elastomer damper. A damper, which may be utilized as a lead-lag damper for a helicopter rotor application, reduces vibratory motion transmitted axially, torsionally and angularly between a pair of components such as a rotor and a blade by hysteresis of the elastomer and throttling and shearing of the fluid through a narrow annular passageway. The hybrid damper captures the best features of both the elastomer and fluid dampers while avoiding many of the disadvantages of each.
