Abstract: Micro wind turbines – an emerging technology, is a new approach for energy conversion. In this paper, a small comparison is made with respect to the dimensions of the normal wind turbine blade and a micro wind turbine blade considering the NACA (National Advisory Committee for Aeronautics) profile. NACA coordinates are used effectively in designing and analysis of various parameters of the aerofoil profile. Thus, for a better understanding of the term micro wind turbine blade, a comparison of the dimension length is conducted using the CAD models designed in CATIA software obtaining the coordinates for the aerofoil profile from NACA.
