Abstract

Horizontal axis wind turbine, characterized of the use of an innovative rotor (7), achieving high power to volume ratio, compared to single row of blades, conventional, horizontal axis wind turbines. The innovative rotor is made up of two rows of blades the stationary, first row (1) and the rotating second one (2). The blade superposition of the first row generates a series of nozzles (5) of suitable cross sections that accelerate the air-flow, which impacts the blades of second row, with optimum angle, causing the power shaft (6) to rotate. Furthermore the so produced energy is transferred classically through a gear-box to the generator.
