Development of Blade Design for Small Hawt Adapted for Lower Values of Wind Speed

Development of Blade Design for Small Hawt Adapted for Lower Values of Wind Speed

The paper aims at studing, theoretically and experimentally, the influence of turbines blade profile on output power, in order to decrease effective domain to smaller wind speed, specific to Galati area. Studies have been made using a type of turbine with variable blade profile and another type usi...
