The invention discloses a small coaxial double-rotor unmanned aerial vehicle, which relates to the technical field of unmanned aerial vehicles. The small coaxial double-rotor unmanned aerial vehicle comprises a vehicle body, an upper rotor mechanism, a lower rotor mechanism, a motor set module and a steering engine module. The vehicle body comprises a machine shell and a center shaft, and the upper rotor mechanism, the lower rotor mechanism and the steering engine module are sequentially installed on the center shaft. The motor set module is used for the rotation of the upper rotor mechanism and the lower rotor mechanism, and the rotation directions of the upper rotor mechanism and the lower rotor mechanism are opposite and are used for offsetting the moment of inertia. The upper rotor mechanism rotates in a fixed-axis mode, the lower rotor mechanism is in linkage connection with the steering engine module, the steering engine module can drive and change the rotating plane of the lower rotor mechanism, then an included angle is formed between the lower rotor mechanism and the upper rotor mechanism, and the variable-pitch function is achieved. According to the small coaxial double-rotor unmanned aerial vehicle provided by the invention, through excellent structural design, the structure of the small coaxial unmanned aerial vehicle is simplified, the reliability is high, the cruising ability and maneuvering characteristics of the coaxial double-rotor unmanned aerial vehicle are enhanced, and the remote point operation requirements can be met.
