The double-duct tilt aircraft comprises duct rotor seats, a machine body, duct rotors, flaps, driven synchronous pulleys, synchronous belts, a driving synchronous pulley, an undercarriage, a turbine, a main wing, a storage battery set, a cockpit, an electronic operating device, a hydraulic power unit, a servo motor, a worm, a worm support, driven bevel gears, driving bevel gear shafts, a kerosene reciprocating engine, first cranks, first hydraulic cylinders, second hydraulic cylinders and second cranks. The flying speed and posture of the double-duct tilt aircraft are controlled by the duct rotors, the flaps and the main wing jointly, so that the double-duct tilt aircraft has the characteristics of being large in lift force, smooth and steady in taking off and landing and high in air flying speed. The cockpit is arranged on utmost upper portion of the double-duct tilt aircraft, so that a pilot has a good sight range, and the operation of the double-duct tilt aircraft is greatly facilitated. The main wing can be driven by the servo motor to rotate by 90 degrees and keep parallel to the machine body when parked, so that space is saved, and traffic jam in a city is eased.
