The invention discloses a coaxial unmanned aerial vehicle and a control method thereof, and belongs to the technical field of coaxial unmanned aerial vehicles. According to the unmanned aerial vehicle, a longitudinal rotating mechanism used for achieving pitching rotation and a transverse rotating mechanism used for achieving rolling rotation are arranged under a coaxial rotor system, and the main structure of each of the longitudinal rotating mechanism and the transverse rotating mechanism only comprises a rotating shaft and a support where the rotating shaft is located; and the lower end of the transverse rotating mechanism is connected with the conventional structure platform and the airborne system. Compared with an existing coaxial unmanned aerial vehicle pitching rotation mode and an existing coaxial unmanned aerial vehicle rolling rotation mode, unmanned aerial vehicle pitching and rolling control is carried out through the rotation pairs, the coaxial unmanned aerial vehicle structure is greatly simplified, the unmanned aerial vehicle structure space efficiency is improved, a complex mechanism of an automatic inclinator and three sets of steering engine systems adopted by a traditional coaxial unmanned aerial vehicle are simplified, and the unmanned aerial vehicle structure space efficiency is improved. And the structure is more compact, parts are smaller, and the reliability is higher.
本发明公开了一种共轴无人机及其控制方法,属于共轴无人机技术领域。该无人机在共轴的旋翼系统下设置了用于实现俯仰转动的纵向转动机构,以及用于实现滚转转动的横向转动机构,其中纵向转动机构和横向转动机构的主要结构均只包括一个转轴和转轴所在的支架,横向转动机构的下端和常规的结构平台以及机载系统连接。相比于现有的共轴无人机俯仰转动方式和滚转转动方式,采用转动副进行无人机俯仰与滚转控制,大幅简化共轴无人机结构,且提高了无人机结构空间效率,简化传统共轴无人机采用自动倾斜器复杂的机构及三套舵机系统,结构更加紧凑、零部件更小、可靠性更高。
