Study Notes
Torsion Link Dampers
- A torsion link damper is a device used to counteract wheel shimmy.
- Wheel shimmy is the fast back-and-forth oscillation of the wheel (left and right) as the aircraft moves.
- Wheel shimmy can be caused by tire pressure variations, uneven wear on the tires, or uneven runway surfaces.
