An oleo-pneumatic shock absorber of a fighter aircraft loses some of its nitrogen charge and oil fill over time, due to leakage through seals. Usually, only gas can be added to shock absorber in line maintenance. This creates an imbalance to the rati

Most of all modern commercial and military aircraft have oleo-pneumatic shock absorbers in their landing gear. An oleo-pneumatic shock absorber consists of a gas charge and an oil fill. During the stroke oil is forced through orifices which provides
