“…Studies that are carried out to optimize the design of wind turbines often lead not to a simplification of the design of the wind turbine but on the contrary, to its complication. In work [26], an installation with an auxiliary wind wheel, which is located on the same axis of rotation with the main wind wheel, is considered. The auxiliary wind wheel has 8-12 blades and is used in a complete set of five types of models of double wind turbines.…”

The object of research is the shape of the blade of a vertical-axis installation. The problem solved in this work is to find the optimal shape of the blade for a wind power installation for operation at low wind speeds or in areas where its flow is limited. In the course of the work, the interaction between each blade option and the wind flow depending on the shape of the blade was considered. With the help of a reduced model of the wind turbine, a flat blade, a blade with a «pocket», and a blade with a «pocket» and a slit were tested. The test results prove the effectiveness of the designed and manufactured blade with a «pocket» and a slit. This was confirmed by the study results, according to which, during the experiment, the number of revolutions of a wind turbine with blades made with a «pocket» and a slit was the largest. In comparison with flat-shaped blades, the increase was 20 %, and, in comparison with blades with a «pocket», the increase was 10 %. In order to compare wind turbines that have flat-shaped blades and blades with a «pocket» and a slit, experimental studies and calculations of the power factor Ср were carried out. A flat-blade wind wheel has Ср1=24; a blade with a «pocket» – Ср2=52.9; a blade that has a «pocket» and a slit – Cp3=58.7. Therefore, one can assume that the power generated by the wind wheel with the above blades is also the largest, Р3=98 W, compared to two other shapes of blades: flat, P1=32.3 W; with a «pocket», Р2=88.2 W. It would increase during the test time from zero speed to reaching a constant rotational speed. The studies confirm that the wind wheel, which has blades with a «pocket» and a slit, has the highest speed of rotation over the entire period of time when measurements were performed

“…The Data has collected to measure the wind speed, the generator shaft's rotational speed, and the resulting electric current. The results showed that wind speeds below 5 m / s are ideal for using three blades and wind speeds of more than 7 m / s are better for using blades of more than 3 [1].…”

The horizontal axis wind turbine (HAWT) design with low wind speed requires blade geometry selection. The analysis uses the potential flow panel method and the integral boundary layer formulation to analyze wind flow around the airfoil. The blade design with the blade element momentum (BEM) theory has an aerodynamic coefficient value along the blade. Power wind calculates to model the wind shear pressure at each blade. This research aims to determine the wind turbine rotor based on the performance, including the power coefficient, tip speed ratio, power, and rpm. The simulation uses an airfoil NACA 4412 which has optimal coefficient lift (Cl) = 1.92 at 190 pitch of angle, coefficient drag (Cd) = 0.0635 at 130 pitch angle and Cl / Cd = 155 at tilt angle = 40. Five models of 2.5 m diameter blades with different angles for each chord. The test results show that the change in the speed ratio affects the power coefficient so that the optimal power coefficient on NACA 4412 in experiment 5 is 0.56, and change in rotation per minute affects the output power so that the rotation per minute and the optimal power in experiment 4 with a value of 374 rpm and 553 W.
