The invention discloses a coaxial multi-rotor unmanned aerial vehicle. The unmanned aerial vehicle is characterized by further comprising a battery assembly mounted in the shell, a first shaft mounted on the shell and coaxial with the shell, a first motor mounted on the first shaft, a second motor mounted on the shell and coaxial with the first motor, and a first rotor mounted on the first motor, the second rotor wing is mounted on the second motor; and the tilting mechanism is mounted on the first shaft and is used for driving the first rotor wing to tilt. According to the unmanned aerial vehicle, the first rotor and the second rotor are coaxially arranged, are located on the two sides of the battery assembly and are equally distributed on the two sides of the center of gravity of the unmanned aerial vehicle, so that pitching and rolling torques generated by air flow are zero, and in the flying process, the two rotors are subjected to the same air incoming flow force; the rotating torques relative to the gravity center are opposite, no matter how the air flow changes, the disturbance torques are mutually offset, no influence is generated on the flight of the unmanned aerial vehicle, and the wind resistance of the unmanned aerial vehicle is greatly improved.
本发明公开了共轴多旋翼无人机,其特征是还包括安装在壳体内的电池组件、安装在壳体上同轴心的第一轴、安装在第一轴上的第一电机、安装在壳体上与第一电机同轴心设定的第二电机、安装在第一电机上的第一旋翼、安装在第二电机上的第二旋翼以及安装在第一轴上用于驱动第一旋翼进行倾转的倾转机构。该发明通过将第一旋翼和第二旋翼处于同轴心的设计布局,且第一旋翼和第二旋翼处于电池组件两侧,平分在无人机重心中心的两侧,这样空气气流产生的俯仰和横滚力矩为0,飞行过程中,两个旋翼受到的空气来流力相同,相对重心的旋转力矩相反,无论空气气流如何变化,其扰动力矩相互抵消,不会对无人机的飞行产生任何影响,使无人机的抗风性大幅增加。
