In this paper, we present a complete optimization loop in order to maximize the efficiency of turbine blades. The optimization of the shape of turbine blades is considered within the context of a whole turbine stage. Thus, also stator/rotor interactions are taken into account. An essential part of the optimization loop is providing gradient information in order to increase efficiency. The derivation of the sensitivity equation and its discretization within the framework of the underlying flow solver is the main part of the paper. The performance of the optimzation loop is demonstrated on a complete turbine stage.
