This letter presents a novel open source design of the Y-shaped hexarotor Unammend Aerial Vehicle (UAV), and proves both in theory real experiments its robustness to failure any propellers. An intuitive geometrical interpretation UAV static hovering ability is presented, through which different coplanar/collinear designs analyzed. Following presented interpretation, we also show conditions that...

This paper deals with the study and comparison of passive and active landing gear system of  the aircraft and dynamic responses due to runway irregularities while the aircraft is taxying. The dynamic load and vibration caused by the unevenness of runway will result in airframe fatigue, discomfort of passengers and the reduction of the pilot’s ability to control the aircraft. One of the objectiv...
