Abstract
An aerodynamic lifting system for a VTOL aircraft is provided that includes a lifting structure defining a leading edge portion, a trailing edge portion, an upper surface extending between the leading edge portion and the trailing edge portion, and a lower surface extending between the leading edge portion and the trailing edge portion. A plurality of leading edge and trailing edge movable flaps, along with leading edge openings and trailing edge openings are employed to direct a flow of air, including along an upper surface of the lifting structure. During transition from a VTOL stage to forward flight, when a first leading edge movable flap is in a closed position, a net forward thrust is provided by the flow of air at the leading edge portion.
