Improvements of turbomachine blade aerodynamic performance require proper tailoring of the three-dimensional blade profile. At the present time, techniques employed to arrive at the initial shapes of the blade geometry are at most quasi-3D methods. These methods cannot model the highly complex three-dimensional flowfield in the endwall regions (secondary flows and clearance effects) and multistage effects (streamwise vorticity and unsteady wakes). In this paper, we summarize our progress in the development of a fully 3D and viscous inverse method to upgrade the blade generation module used in existing blade design systems. This new 'blade-geometry generation' module will help turbomachine designers to design high-efficiency blades and shorten the blade design cycle. The work described here is critical to the development of high-efficiency turbomachine components for advanced utility and industrial gas turbines.
