Which function is associated with the shock strut?

• A. Dampens movements
• B. Absorbs shock of landing
• C. Connects bogie to aircraft structure
• D. All of the above

Answer: (D)

The shock strut serves as the main spring-damper and load path for the landing gear, tying the wheel assembly to the airframe while cushioning energy and controlling motion. It dampens movements by regulating how quickly the gear compresses and rebounds, which helps prevent excessive bouncing after touchdown or during taxi and takeoff. It also absorbs the shock of landing by compressing under the impact loads and converting that energy into spring force and heat, protecting the airframe from sudden, harsh loads. In addition, it provides the essential connection between the bogie (the wheel assembly) and the aircraft structure, transmitting vertical and other loads into the airframe while allowing necessary articulation. Because it performs all these roles, “All of the above” best captures what a shock strut does.
