FIELD: aviation.
SUBSTANCE: invention relates to transformable aircraft with a short takeoff and landing for off-aerodrome operation. Convertoplane includes a fuselage, two pairs of wings with a tandem arrangement, propeller-driven installations suspended under the rear wing, and two telescopic rotors "Flettner", transversely located in the middle of the fuselage, on opposite sides of the center of gravity of the convertoplan. Rotors are filled with air with a pressure greater than atmospheric pressure. After takeoff and climb, the rotors are retracted into the fuselage.
EFFECT: invention is aimed at widening the range of equipment.
