3D design
Today, 3D methods are used to design the blading of turbomachinery components (compressors and turbines). This means that the airfoils are no longer designed section by section to obtain the necessary deflection of the gas flow but over their entire radial height so that a rather uniform load distribution is achieved and local flow separations and excessive losses are prevented. A 3D airfoil deflects the flow in circumferential direction and also radially. Thus, the flow through the blade row is uniform and losses are minimized.
