The proposed convertiplane has the ability to take off like a helicopter and then fly horizontally like a conventional aircraft. The aircraft comprises: -a variable incidence front wing of variable span located below the fuselage and mounted on a structure in the form of a venturi tube; -a rear wing having two propellers for controlling the stability of the vehicle in pitch and roll installed therein; -two counter-rotating, pivotally mounted ducted propellers equipped with four flaps orthogonal to each other provided on the sides of the cockpit; -engines placed behind the cockpit close to the center of gravity; -a static balancing system for controlling the center of gravity of the aircraft consisting of a weight placed in the lower part of the fuselage, self-propelled on the track rack longitudinally to the fuselage; -digital flight control system.
