Multi-shaft power source unmanned flying device

The invention discloses a multi-shaft power source unmanned flying device, and belongs to the technical field of unmanned aerial vehicles. The multi-shaft power source unmanned flying device comprises a frame, a plurality of rotor wing sets and power devices, wherein the rotor wing sets are rotatably fixed onto the frame, and the power devices are correspondingly movably connected with the rotor wing sets. The power devices with oil drive characteristics provide power for flying of the unmanned flying device, mechanical kinetic energy is generated by burning combustion materials prefilled in the power devices, rotor wings in the rotor wing sets correspondingly connected with the power devices are driven to rotate, a traditional electric multi-rotor unmanned aerial vehicle structure adopting electric modes such as batteries and electronic speed controllers to supply power and provide power for rotation of the rotor wings is replaced, and the multi-shaft power source unmanned flying device has the advantages of long time of endurance and high loading capacity.
