- Sinônimos
- nose wheel shimmy dampener
- Definição1
- A small hydraulic shock absorber installed between the nose wheel fork and the nose wheel cylinder which is attached to the aircraft structure. The piston inside the shimmy damper cylinder is free to move back and forth when it is moved slowly enough to allow fluid to transfer from one side of the piston to the other through a restrictor. Slow movement of the piston allows the nose wheel to pivot so the aircraft can be steered on the ground. But, the restrictor slows the flow of fluid inside the cylinder and prevents the piston from moving back and forth as fast as it would if the nose wheel were shimmying.
