An oil-drive variable-pitch multi-rotor aircraft relates to the field of aircrafts, and is designed mainly aims at solving the problem that a conventional multi-rotor aircraft is large in volume, complex in structure and the like. The oil-drive variable-pitch multi-rotor aircraft comprises a cabin and an undercarriage, the cabin is inside provided with a fuel tank and an engine; each aircraft arm connected with the cabin is inside provided with a transmission shaft, bevel gears at the inner ends of the transmission shaft are engaged with a driving fluted disc on an engine power take-off shaft, and each aircraft arm is provided with a rotor driving mechanism; a reduction gearbox of each rotor driving mechanism is inside provided with a main shaft fluted disc, the bevel gears at the outer ends of the responding transmission shaft are engaged with the main shaft fluted disc, the main shaft fluted disc is installed on a main shaft, and the main shaft is in the reduction gearbox and stretches out of the reduction gearbox, the main shaft is sleeved by a variable-pitch disc, a rotor head is fixedly disposed at the top of the main shaft, the rotor head is connected with a rotor clamp, and a rotor single body is connected with the rotor clamp; the distance of the adjacent aircraft arm outer ends is smaller than the length sum of two rotor single bodies and is larger than the length of one rotor single body; and the length of one aircraft arm is larger than the length of one rotor single body. The advantages comprise that the volume is small and the structure is simple.
