The invention discloses a variable-pitch coaxial oil-driven six-rotor helicopter. The variable-pitch coaxial oil-driven six-rotor helicopter comprises a coaxial rotor-operating system, a power system-transmission system and a frame system, wherein the coaxial rotor-operating system and the power system-transmission system are mounted on the frame system. According to the invention, problems of the low load, short endurance, poor wind resistance and the like in the traditional electric multi-rotor helicopter are mainly solved; and problems of high purchase, use and maintenance cost, high use and maintenance technical threshold and the like caused by complicated mechanical structure, structural dynamic characteristic, flight dynamical characteristic, aerodynamic characteristics and flight control system in the traditional helicopter are also solved.
