The purpose of this study was to determine the differences of kinematics, impact force, soft-tissue vibration, and muscle activity between active (AL) and unexpected landing (UL). Twelve trained male volunteers were requested to land from self-made elevated platform at three heights (30, 45, and 60cm) in AL and UL conditions. During active landing, human body can adjust the landing strategy of ...

Acoustic emission monitoring was completed on a painted aerospace grade steel landing gear component undergoing fatigue loading until rupture. A post-test linear location analysis of the collected signals revealed eleven groups where high activity (greater than 2000 hits) occurred within a defined location, three of which corresponded in location to the position of fracture and final rupture of...

A case study problem based on a set of aircraft landing gear is examined in Hybrid Event-B (an extension of Event-B that includes provision for continuously varying behaviour as well as the usual discrete changes of state). Although tool support for Hybrid Event-B is currently lacking, the complexity of the case study provides a valuable challenge for the expressivity and modelling capabilities...
