Abstract
A development of landing gear drop test rig system for a small aircraft was studied and presented in this paper. Hydraulic actuators were considered in order to operate test system automatically and the wire winch system was applied to keep safety of test operators. This rig system was manufactured after checking the structural stability. Friction force measurement and drop velocity evaluation tests were done to confirm the confidence of test system. As a results of evaluation tests, it was confirmed that developed landing gear drop test system was adaptable.
