Rubber disc shock absorbers

Definition

Rubber disc shock absorbers are components used in landing gear systems to absorb the shock and vibrations experienced during landing and taxiing. They consist of stacked rubber discs that compress and expand to dampen impact forces, providing smoother landings and protecting the airframe from stress. These shock absorbers are essential for maintaining structural integrity and enhancing passenger comfort during flight operations.
