Wind turbine of low wind speeds

Horizontal axis w/t of low wind speeds of propeller type, bearing a main rotor of three blades (1), while in the space between two successive blades (1) and diametrically opposite to the third, an additional 4th blade (2) also of propeller type but of significantly longer length, is interposed. This additional blade (2) is not permanently coupled but selectively engaged in the system of the w/t at low wind speeds, contributing to the startup and enhancing the energy production.
