The current global situation determines researchers and design engineers to make the production process of wind turbines energy efficient. Against the backdrop of increasing electricity consumption, one of the viable solutions is the design of blades with optimized aerodynamic profiles. The objective of this article research is to design and validate in the virtual environment the aerodynamic advantages of a modified NREL (National Renewable Energy Laboratory) blade profile. Our team’s work was aimed at improving the existing performance of 5 MW turbines equipped with NREL three-blade rotor type. After analyzing the results provided by various other research studies, we followed the effects of the aerodynamic lift obtained with a new blade shape. The theoretical test method used the Ashes software. The results reveal graphical representations of the main parameters and system indicators, demonstrating benefits of the new profile. The new aerodynamic profile with modified tip of the blade shows superior properties compared to the standard NREL 5 MW model, by a surplus of 0.11% electricity through more efficient wind energy processing.
