Design and Production of an Osprey-type Drone with 2-DOF Tiltable Mechanisms

Vertical-takeoff-and-landing unmanned aerial vehicles (UAVs) are known as drones and used in a wide range of fields. In general drones, the rotor is fixed to the fuselage, and can only output thrust in one direction, which causes the aircraft to change its attitude when moving. In this research, it is aimed at creating a UAV that can flexibly fly without causing any changes in attitude when navigating. There was a flight limitation due to the total weight of the airframe in a previously studied UAV, which was a tandem-type rotorcraft having 2-DOF tiltable coaxial rotors at front and rear respectively. This research solves this problem and develops a new Osprey-type drone that can fly without such a limitation.
