US Patent 11118564 Fluid flow energy extraction system and method related thereto

Disclosed is a system and method for both consumer and utility scale energy extraction from flow-based energy sources. The passive system may utilize directing perforations on a surface in order to create and air jet vortex generators. Alternatively the system may provide for flow through discrete orifices aligned with the span of an aerodynamic assembly in a co-flow direction, utilizing a Coanda effect. Further additional configurations include directing flow through a perforated surface skin that is near the trailing edge on the suction side. Even further are embodiments for blowing air directly out of the trailing edge of an airfoil. The disclosed systems and methods support a wide variety of scenarios for fluid flow energy extraction, such as wind or water flow, as well as for related products and services.
