A
Abstract:
A lift cell comprising an airfoil section or sections containing a plurality of airfoils enclosed within an enclosure and a device for forcibly moving air through the airfoil section or sections. The airfoils are shaped and arranged so that airflow past each airfoil creates a pressure differential acting on the airfoil to produce lift, the combined lift on each airfoil in the enclosure producing lift on the lift cell.
