Main landing gear of a high-altitude long endurance UAV was modeled as a mass-spring-damper system in this study. Landing gear components including the oleo-pneumatic shock strut, tire, and wheel were included in the constructed model in the study. An oleo-pneumatic shock absorber with fixed orifice area was used in the model and dynamic behavior of the system was investigated. A representative input dataset for UAV specifications and oleo-pneumatic shock absorber characteristics were collected from literature to form the input dataset, and dynamic model was solved with using computer software. Three main cases were run in accordance with the CS-25 certification requirements which are at 1.83, 3.05, 3.7 m/s (6,10,12 fps) descent velocities and lift equals to weight condition. Within the constraints, the results are satisfactory and can be used as a baseline configuration to be optimized in future research.
