If i am not wrong, there is shimming damper at aircraft nose gear. Anybody have any idea about what's the device for?

Fred, I assume the device is to dampen out oscillations of the nose wheel after landing, hopefully keeping the craft pointing straight down the runway? Is it supposed to assist in, um, 'sideways' landings made in a crosswind?
Lord is a manufacturer that specializes in vibration absorption. They make mounts for engines, drive shaft, etc...brewnog said:Nice animation. Why does the damper say 'lord' on it?!
Cyrus said:Never even heard about it until this thread, but http://www.ae.go.dlr.de/dyn/research/shimmy/anims/shimmy-damper_anim.gif a nice animation.
Shimming of nose landing gear is a process used to adjust the alignment of the nose landing gear of an aircraft. It involves placing thin metal shims between the landing gear components to correct any misalignment and ensure proper functioning of the landing gear.
Shimming is necessary for nose landing gear because even small misalignments can lead to uneven weight distribution and increased stress on the landing gear components. This can affect the stability of the aircraft during takeoff and landing, and can even cause damage to the landing gear.
The process of shimming nose landing gear involves carefully measuring the alignment of the landing gear components using specialized tools. Based on these measurements, the appropriate shims are selected and placed between the components to correct any misalignment. The process may need to be repeated multiple times until the desired alignment is achieved.
The responsibility for shimming of nose landing gear typically falls on the maintenance or engineering department of an airline or aircraft manufacturer. Trained technicians or engineers are tasked with performing the shimming process to ensure the safety and proper functioning of the landing gear.
The frequency of shimming nose landing gear depends on various factors such as the type of aircraft, the amount of wear and tear on the landing gear, and any previous shimming adjustments. In general, it is recommended to perform shimming during routine maintenance checks or whenever there is noticeable misalignment or issues with the landing gear.
