Abstract

We consider the issues of transforming the blade geometry, which is conventionally defined as a set of points over several cross-sections, to parametric form that is necessary for the computer-aided solution of optimization problems. The method for coordinated movement of blade profile points under deformation within the optimization problem and the method of coordinated change of the profile parameters over the blade height, are proposed. An algorithm for the analytic representation of the profile specified discretely without loss of accuracy is described.
