The invention discloses a coaxial dual-rotor unmanned aerial vehicle. The coaxial dual-rotor unmanned aerial vehicle comprises an upper rotor fixing assembly, a lower rotor fixing assembly, a coaxial motor, a nose tilting mechanism and a PCBA which are coaxially arranged, the outer side of the upper rotor wing fixing assembly and the outer side of the lower rotor wing fixing assembly are each symmetrically provided with a set of blades. The lower rotor wing fixing assembly sleeves the top of the coaxial motor and is connected with an output shaft of the coaxial motor, and the other output shaft of the coaxial motor penetrates through the lower rotor wing fixing assembly and is used for mounting the upper rotor wing fixing assembly; when the coaxial motor rotates, the upper rotor wing fixing assembly, the lower rotor wing fixing assembly and the upper blade paddles are driven to rotate in opposite directions; the coaxial motor is fixedly installed above the machine head inclining mechanism, and the machine head inclining mechanism drives the coaxial motor and components above the coaxial motor to incline in different directions. According to the unmanned aerial vehicle, the coaxial motor and the components above the coaxial motor are driven by the nose tilting mechanism to tilt in different directions, so that the precise control of the tilt angle is realized, and the flight direction of the unmanned aerial vehicle can be precisely and sensitively controlled.
