Aerospace and Mechanical Engineering2019<p>The paper describes the constructing algorithm for radial-axial turbine rotor blades using Bezier curves. The surface of the blade obtained by this algorithm is monotonically changing curvature and it impact positively on efficiency. In addition, blades are radial in all section perpendicular to the axis of rotation; it can significantly reduce the bending stresses in the blade body.</p>Радиально-осевая турбинапрофилированиемеридиональное сечениерабочая лопаткикривая БезьеRadial turbinesbladingmeridional sectionrotor bladeBezier curve
