Design and Experiment of a Distributed Tiltrotor UAV

With the development of unmanned aerial vehicle (UAV) technology, new UAV designs have become a research hotspot. Addressing the issues of short flight time, low flight speed for multirotor UAVS, and higher takeoff and landing environment requirements for fixed-wing UAVs, this paper proposes a distributed tiltrotor UAV system. First, it introduces the current research progress on vertical takeoff and landing (VTOL) tiltrotor UAVs. Next, it describes the overall design and components of the distributed tiltrotor UAV. The paper then provides a detailed introduction to the avionics system design for this UAV, and to the redundant flight control system. Following that, it presents a detailed analysis of the UAV control methodology. Finally, by constructing a prototype and conducting flight tests, the feasibility of this UAV as a novel rapid VTOL platform is validated. The results indicate that this UAV can achieve stable and reliable flight, offering valuable insights for the design of future VTOL UAVs.
