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 3<sup>rd</sup> model is a semi ellipse without a stabilizing plane; the 4<sup>th</sup> model is a semi ellipse with a stabilizing plane.</p>Лопастьвертикальная ось вращенияаэрогидродинамический коэффициент[1.
