This book is a support tool for the design of a statoéolien. It consists in making the installation more efficient by relying on the venturi effect which is the convergence of the fixed blades and by removing the surface friction effect of the blades. The concept of the wind turbine is based on the placement of the stator which plays an important role in channeling the wind flow to the rotor as well as increasing the wind catchment area. Improving the condition of the outer surface of the blades by painting and varnishing promotes the aerodynamics of the wind turbine. Our choice on the structure and sizing of the equipment depends on several parameters. Experimentally, it has been observed that the statoéolien with four movable blades and six fixed blades is more advantageous. Precise and professional computer aids tools such as the Ret'screen to collect the climatic data of the place, the computer-aided design software SolidWorks, our EolEstim software designed on Microsoft Visual Studio under C ++ programming language to estimate the recovered power allow the performance of the statoéolien to be evaluated.
