This study focuses on the design and experimental analysis of an aerodynamic blade profile for a horizontal axis dual-stage small-scale wind turbine. Vietnam, with its extensive coastline and favorable wind conditions, holds significant potential for wind energy development. The designed turbine features aerodynamic blades combined from three different profiles, aiming to maximize energy capture and ensure durability under harsh weather conditions. Experimental results demonstrate that the new aerodynamic blade profile significantly outperforms the traditional straight-profile blades in terms of power output at various wind speeds. On average, in the range of wind speed testing, the power output of wind turbines with aerodynamic blades increases by about 50% compared to that of wind turbines with straight-profile blades. This research not only enhances the efficiency of small-scale wind turbines but also provides valuable insights for the deployment of these turbines in residential and small community settings.
