| Abstract: | The Variational FE calculation is carried out in this paper foe the hybrid aerodynamic problem of Type-C of cascades on an arbitrary streamsheet of revolution in terms of the angular function. The thickness distribution of the blade and the pressure (or velocity) distribution on the suction surface of the blade are specified to calculate the blade contour and the flow field characteristics.Two examples of calculation (including radial and axial cascades) illustrate that the method provided in this paper is highly effective and widely applicable. |
