Combined blade and turbine design for improved utilization of fluid flow energy

摘要

The invention relates to a device for producing electrical or mechanical energy by means of wind or other fluid boundary layer currents. This is done by blocking off part of the flow via an edge wing (i), alone or in combination with a longitudinal wing (2). The invention comprises an edge vane (i), a rotor (5), a bottom profile (2), lamellae (3) for focusing the flow The invention differs from corresponding inventions by using static shut-off of fluid flows to create increased pressure drop over the turbine run (8), thereby increasing the flow through the turbine run (8). The invention is characterized by being advantageous to be placed on landscape projections or buildings, where boundary layer flows are naturally compressed with an increased flow rate. The invention is characterized by being capable of being arranged as an integral element which fits into existing buildings or landscape structures, or as an additive element which is placed on top of existing buildings or landscape structures. The invention is characterized by increasing the efficiency of already known or new rotor types. The invention provides an effective alternative to free standing house wind turbines.
