Aerodynamics Design Of Diagonal Impeller And The Blades Design

The main object of this paper is to design a diagonal impeller, which requires small size and high rotating speed .The first step of the design is to solve the radial equilibrium equations on the S2 stream surface . Second , the blades designed according to the results of the first step. A method presented for designing diagonal impeller blading from blade elements defined on cones which pass through the blade-edge streamline locations. The staking line for the blade elements can be leaned in both the axial and tangential directions.
