Краткое описание

According to wind turbine investigations by N. E. Zhukovsky and A. Betz, the maximum wind power coefficient ξ = 59.3%. This result is obtained from the solution to the problem of the flow about multiblade coaxial wind turbines with straight blades. The present paper shows that the use of scimitar-shaped blades increases coefficient ξ.
