Kinematic Singularity and Bifurcation Analysis of Sidestay Landing Gear Locking Mechanisms
International Journal of Aerospace Engineering, 2021 A dual-sidestay landing gear is prone to locking failure in the deployed state due to the restriction of movement between two sidestays. However, the principle of its locking movement still remains unclear. The present study is aimed at investigating the
