What is the primary function of a shock strut assembly in an aircraft?

The primary function of a shock strut assembly in an aircraft is to absorb shock from landing. When an aircraft lands, the impact generated can exert significant forces on the landing gear. The shock strut assembly, which typically consists of both a hydraulic cylinder and an air/oil damping system, is designed to cushion these impact forces. By doing so, it helps protect the airframe, landing gear, and other structures from damage that could arise from harsh landings.

Effectively absorbing shock enables the aircraft to maintain stability and control during landing operations. The hydraulic fluid within the strut not only provides the necessary damping effect but also helps to support the weight of the aircraft while allowing for some compression, which is crucial during the landing process. Overall, the shock strut assembly plays a vital role in ensuring a smooth landing experience and promoting the aircraft's overall longevity and safety.
