“…Compared with the other three samples at 30 0 , 45 0 and 60 0 , at 0 0 , the combined blade produces maximum lift and minimum drag force. Compared with the experimental results of cylinders of different shapes (with a porous surface, with a deflector) [21][22] the obtained numerical data of the lift coefficient is almost 2 times higher, which makes it possible to assert that a combined blade is much more efficient than a single cylindrical blade and a blade from a cylinder with a deflector. Below is the dependence of the number of revolutions of the blade on the wind speed at different angles of attack (Fig.…”

To increase the energy efficiency of wind turbines, it is necessary to optimize and improve the shape and size of power elements. In this work, in order to improve the output energy indicators, as well as increase the lifting force, a combined blade in the form of a rotating cylinder and a fixed blade was created and numerically studied. The novelty of the work lies in obtaining the results of the influence of a fixed angle of inclination of the blade on the overall aerodynamic characteristics of the entire combined blade at wind speeds from 3 to 12 m/s. Based on three-dimensional modeling, 4 variants of the combined blade with different angles of location are designed. Three-dimensional patterns of the distribution of velocity vectors and pressure fields are obtained. Linear graphs of the dependence of aerodynamic coefficients on the Reynolds number are shown. It was found that at an angle of 0 degrees, the combined blade has a maximum lift coefficient of 10 and a minimum drag coefficient of 4.5 at Reynolds 1·104. The numerical results obtained will be useful in the development of wind power plants with combined blades operating on the basis of Magnus.

“…2). Focusing on the highly effective results of the well-known works of such several authors as N.K.Tanasheva and Dyusembaeva [19,[21][22], an optimal cylindrical blade with a diameter of 50 mm and a length of 300 mm was created. The width of the fixed blade was 33 mm, and the length was 300 mm.…”
