Identify a common type of shock absorber used in landing gear systems.

A common type of shock absorber used in landing gear systems is the oleo strut. Oleo struts operate using a combination of compressed air and hydraulic fluid, providing effective damping of energy during landing and taxiing. As the aircraft lands, the strut compresses, allowing the hydraulic fluid to flow and absorb impact, creating a smoother ride and reducing stress on the aircraft structure.

The design of the oleo strut allows it to respond dynamically to changes in load and speed, making it suitable for various aircraft types. Its ability to provide consistent damping characteristics under different conditions differentiates it as a reliable shock absorber in aviation applications. This system helps to ensure the stability and comfort of the aircraft while on the ground and during flight operations.

In contrast, other types of struts, such as spring struts and rubber struts, may not provide the same level of adaptability or effective shock absorption under varying load conditions, limiting their use in more advanced or heavier aircraft. Meanwhile, air struts are primarily pneumatic and may lack the fluid damping properties found in oleo struts, which are crucial for landing gear.
