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