    • PROBLEM TO BE SOLVED: To provide a rotary vane with a rotating duct system shroud capable of solving a problem that a conventional rotary vane with a shroud makes it difficult to revolve a rotating part due to deflection and distortion of a rotor blade or pressure due to centrifugal force and heat, etc. in using it with a large aperture and at a horizontal position even when there is no problem in using it with a small aperture and at a vertical position and increases weight as structure becomes complicated in maintaining extension and contraction properly by an electromechanical device. SOLUTION: This rotary vane with the rotating duct system shroud is capable of constantly and stably rotating and generating lift and thrust even in using it with the large aperture and at the horizontal position and in giving sudden directional change by mounting it on a turn table by constituting it so that a permanent magnet is arranged on an outer periphery of the rotating duct, the rotor blade having rotary supporting parts almost every 2.5m is connected to an inner peripheral part of the rotating duct, the shroud and the rotating duct make constantly contact with each other in the vertical direction and extension and contraction of the rotating duct, the rotor blade, etc. is maintained by properly holding an interval in the horizontal direction between an inner peripheral part of the shroud and the outer peripheral part of the rotating duct.
