06/21/2012US20120156037 Foil, utilized such as an airfoil or hydrofoil, characterized by a duct moving relative to a mass of fluid. A constriction within the duct increases the speed of the fluid flowing within the duct and thereby produces a pressure drop inducing a mass of fluid external to the duct to accelerate into the duct. The acceleration of the fluid into the duct generates a resultant force, which can be varied and controlled to improve performance and reduce drag
