Aerolift systems and methods using air ducts and lifting bodies

Abstract

Aerolift systems and methods using one or more air ducts and one or more lifting bodies. The duct may have a turn angle from the inlet to the outlet. The duct may have a variable cross-sectional area, such as increasing from inlet to outlet. The lifting body may be an airfoil. A propulsion unit, such as an electric motor and rotating blades, moves air through the duct and to the lifting body. The flow of air against and/or over the lifting body creates an aerodynamic lifting force. The flow of air downward may provide lift. The total lifting force may be used to move a moveable component. The aerolift system may be used in various applications, including aircraft and industrial systems. An aircraft may include the lifting body, or multiple lifting body segments, defining an annular shape, such as rounded or polygonal.
