<p>PROBLEM TO BE SOLVED: To reduce a defect of causing wind blast damage to the periphery or generating remarkable noise upon takeoff and landing, such as of a helicopter as a vertical takeoff and landing vehicle based on a new fluid dynamic principle, and achieve high speed rotation by enabling the size increase of the airframe that has been impossible with a helicopter.SOLUTION: Floating the airframe by utilizing a lift force generated in the top face of a rotary disc 1 located in the upper part of the airframe body 2 to rotate at high speed is made to serve as its vertical takeoff and landing flight principle to enable free movement of vertical rise and fall and aerial halt and the subsequent takeoff and landing by adjusting the magnitude of the rotational velocity of the rotary disk, that is, the strength of the lift force acting toward the upper part of the airframe, and to increase the size of the airframe by pluralizing the disc cardinal number, and to enable high-speed flight by forming the outer shape of the entire airframe into a smooth streamline without protrusions or modifications.</p> |
