A generator of aerodynamic force by rotational movement, by means of a device which, starting from a rotational movement, induces a field of velocities in the surrounding fluid, which produces a difference in pressure on a surface, which in turn results in an aerodynamic force. The rotor element (1) is set in rotation at high speed by a motor (3). The rotational movement of the rotor element causes the fluid in which the device is immersed to assume a rotational movement, the velocity of the fluid layer that is in contact with the cylinder being equal to the velocity of a point at the surface of the cylinder. The planar element (2) separates the fluid into two regions. The fluid in the region below the surface is motionless, whereas the fluid above the surface is in motion. Since the higher the velocity of the fluid the lower its pressure, the fluid in the region below the surface exerts a higher pressure than that exerted by the fluid in the region below the surface. This difference in pressure results in a force that acts on the surface.
A device for generating an aerodynamic force for lifting an object comprising a rotor means being symmetric in relation to an axis characterized by comprising continuous closed peripheral wall and a substantially planar means positioned close to rotor means and perpendicular to said axis, determining respective upper and lower fluid regions at opposite ends of said substantially planar means said substantially planar means having an average diameter which is greater than the average diameter of said rotor means, a motor means driving said rotor means thereby causing fluid layers adjacent to said rotor means in said upper fluid region to circulate in substantial unison with said rotor means in rotational movement around said axis, and a second peripheral wall around and adjacent to said substantially planar means.
