Abstract

A methodology for the full three dimensional automatic design of turbomachinery airfoils is presented, developed with the requirement of minimal output time. This requirement leads to the use of a gradient based algorithm, where derivatives are computed using the adjoint method. Where possible, the computational advantages of Graphics Processing Units have been used, qualitatively and quantitatively assessing the benefits of this ap-proach. In order to illustrate the capabilities of the system, a Low Pressure Turbine vane has been redesigned, taking into consideration a set of rigorous design criteria.
