Description: In this work, the optimization of wind turbines is considered by introducing a cylindrical blade with an activedeflector. The use of metal (aluminum) deflector, compared with plastic (polypropylene), significantly increasedthe aerodynamic efficiency of the blade. It is shown that the aluminum deflector reduces the dragforce by 18–20 % and increases the lifting force by 2.7 times. The maximum lifting force reached 2.16 N at awind speed of 15 m/s with an aluminum deflector. In addition, the blade with an aluminum deflector achieveda higher rotation speed — up to 1100 rpm, which is 10 % higher compared to the blade with a polypropylenedeflector. The improved performance is due to the high rigidity and minimal deformation of the aluminummaterial under the influence of air flow. The use of an active aluminum deflector eliminates the need for additionaltriggers, simplifying the design and reducing operating costs. The results obtained indicate that the useof an active aluminum deflector increases the efficiency of Magnus wind turbines and contributes to the developmentof renewable energy technologies.
