In recent years, the rotors for small wind turbines designed to have low tip speed ratio are increasing in number because of their reduced noise. The development of generators and controllers suitable for low rotational speed is largely accelerated these years. Various studies have been carried out in Japan and abroad. Most of these, however, are just additional work on blades made by using common design techniques that follow the Blade Element/Momentum Theory (BEM). By the switch of the idea, therefore, we decided to investigate blade shape starting with basic notions such as the leverage principle, the action-reaction law and Bernoulli's theorem, in order to address requirements for wind turbines used in urban environments.
