Optimal Shape Design of Turbine Blades

This paper attempts to present a general engineering method for minimizing the weight of rotating turbine blades in optimizing the cross section shapes. The constraints originate from either aerodynamic or solid mechanic specifications. As the problem is reformated after a first F.E. analysis, the optimization process is quite inexpensive. A large variety of compressor or turbine rotating blades can be designed by this method which uses the variables selected by the aerodynamicists and leads to continuous optimal profiles.
