Testing the blades of turbines of windmills and hydraulic motors, with the vertical axis of rotation

Abstract

The paper deals with the results of testing blades of turbines with a vertical axis of rotation, namely the definition of their aerohydrodynamical characteristics. Four models of blades were tested: the first model of the blade represents a semi ellipse with a semicircumference inserted in a concave part of the semi ellipse without a stabilizing plane; the second model represents a semi ellipse with a semicircumference inserted in a concave part of the semi ellipse with a stabilizing plane the width of which is equal to of the diameter of the semicircumference; the 3rd model is a semi ellipse without a stabilizing plane; the 4th model is a semi ellipse with a stabilizing plane.
