The invention discloses a hybrid power device of a small aviation aircraft. The device is characterized by comprising a fuel oil power system which is provided with a piston engine and an oil tank used for supplying oil to the piston engine; the device further comprises a power system which is provided with a generator, a battery pack and a motor, the generator is driven by the piston engine to generate alternating current, the alternating current is converted into direct current through a rectifier to charge the battery pack, the battery pack supplies power to the motor, and the motor drives a propeller to rotate; and the device further comprises a hybrid power management system which can monitor the working states of the piston engine and the motor and control the piston engine and the motor to work. According to the invention, the piston engine drives the generator to generate electric energy, the motor drives the propeller to work, and the engine works near the economic working condition for a long time, so that the fuel consumption rate is kept at a lower level, and the cruising ability and extra task loading capacity of the existing small unmanned aerial vehicle can be effectively improved.
