Study Notes
Nose Gear Shimmy Dampener
- The shimmy dampener is designed to provide resistance to shimmy in the nose gear.
- The dampener works by forcing hydraulic fluid through small orifices in a piston.
- The dampener piston shaft is stationary, secured to a non-moving part.
- The housing of the dampener is secured to the nose wheel steering collar, which moves when the nose wheel turns right or left.
- The relative motion between the dampener shaft and housing helps to resist shimmy.
