FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to multi-rotor aircraft. Universal multifunctional aircraft of quadrocopter type includes body including upper and lower power belts, between which central part of aircraft structure is formed. Upper power belt includes distributing reduction gear having a housing inside which there are five gears. Four pulleys of driving belts are brought out on top of the distributing reduction gear at one level in the horizontal plane. Four cantilevers are attached to the housing of the distributing reduction gear, each of which contains a drive with a toothed belt, a rotor with two rectangular metal blades and a control system for changing the pitch of the blades. Each cantilever at its end has a fork with possibility of linear movement for adjustment of toothed belt tension. In the central part of the spatial volume of the vehicle structure there is a seat of the pilot and/or additional cargo, behind which the internal combustion engine is mounted.
