Which component is known to affect the stroke limitation in oleo shock struts?

The stroke limitation in oleo shock struts is primarily affected by the sleeve, spacer, or bumper ring. These components are integral to the design and function of oleo struts, which are used in aircraft landing gear to absorb shock during landing and taxiing.

The sleeve and spacer determine the volume and thus the amount of hydraulic fluid that can be displaced within the strut during operation. When the landing gear compresses upon impact, the fluid is forced through or around these components. The bumper ring serves as a cushion to limit the extent of the shock strut's compression and helps smooth out the landing effect by providing a controlled stop for the movement of the strut. This mechanism ensures that the stroke, or the extent to which the strut can compress, is maintained within safe and functional limits, protecting the aircraft structure and enhancing passenger comfort.

In contrast, while hydraulic fluid type, landing gear doors, and the brake control system are important to the overall operation and safety of the landing gear, they do not directly influence the stroke limitation of oleo shock struts. The hydraulic fluid type could slightly affect the damping characteristics, but it does not limit the stroke itself. Landing gear doors are primarily concerned with the aerodynamic streamlining of the aircraft and
