Abstract: IMPROVED HELICOPTER ROTOR LEAD LAG DAMPER A helicopter rotor lead-lag hydraulic fluid damper has an internal anti-torque shaft preventing rotary motion of the dynamic fluid retaining seal. An independent fluid reservoir under centrifugal force supplies lubrication to the low-pressure side of the seal. At rest, the fluid returns to the lower reservoir chamber by gravity.
