<p>The present invention relates to a high output motor-driven unmanned multi-copter of a self-power generation type using liquid fuel and an engine. The unmanned multi-copter comprises: 2-20 blade support parts (210) radially extended from a copter body (200); driving motors (220) fixated on the outside of the blade support parts (210); propelling blades (230) rotated by the driving motors, respectively; and a take-off and landing part (300) downwardly fixated on the bottom of the copter body (200). Also, the unmanned multi-copter additionally comprises a power supply part (100) using liquid fuel and an engine. The power supply part (100) comprises: a liquid fuel tank (10); an engine (20) ignited by the fuel received from the liquid fuel tank (10) to produce rotation power; a power generator (30) to produce electricity using the rotation power generated by the engine (20); and an AC to DC converter (40) to convert alternating current produced by the power generator (30) to direct current.</p> |
