The invention discloses an oil-driven four-rotor-wing unmanned aerial vehicle. The oil-driven four-rotor-wing unmanned aerial vehicle comprises four rotor wings and an aero-engine, wherein each rotor wing comprises two ribs; each rib is connected with a corresponding paddle hub; the aero-engine is used for transmitting power to four groups of speed changing boxes through four crossly-arrayed transmission shafts via a speed reducing box, and the two paddle hubs connected with the two rotor wings are controlled by the speed changing boxes through a servo steering engine and a pitch varying system to realize corresponding movement; and the oil-driven four-rotor-wing unmanned aerial vehicle further comprises a control system. The oil-driven four-rotor-wing unmanned aerial vehicle takes gasoline/aviation coal as fuel and takes the small-size aero-engine as power; a lifting force system adopts a helicopter rotor wing form; and a manipulation manner adopts a constant rotary speed and variable paddle pitch manner. The oil-driven four-rotor-wing unmanned aerial vehicle has the characteristics of long endurance time, great loading capacity, good maneuvering performance, strong anti-wind capability and the like. The work task requirements of almost customers can be met.
