Abstract
A rotary aeronautical lifting cell having an annular airfoil, airfoil dividers, and a propulsion mechanism. The airfoil dividers separate the annular airfoil into airfoil sections arranged in circular relationship. Upon rotation of the present aeronautical cell, the airfoil sections provide components of lift and propulsion to transportation vehicles attached thereto.
Claims6
A rotary aeronautical lifting cell for use in a fluid, the cell comprising:
- a. an airfoil having a bottom surface and an upper camber surface, the airfoil being an annular ring of an airfoil having a center fluid intake, the airfoil having an inner edge and an outer edge;
- b. a top element;
- c. a fluid propulsion system for propelling the fluid over the upper camber surface of the airfoil and below the top element;
- and
- d. a motive source to rotate the cell;
- wherein rotation of the cell forms a lower pressure above the upper camber surface than the pressure below the airfoil.
