Within the scope of the present publication, the aerodynamic design optimization of the RACER compound helicopter blade-sleeve fairing is at focus. For this purpose, a sophisticated optimization tool chain allowing for automated aerodynamic design optimization is developed and the demonstration of its functionality is presented. The actual tool chain represents a modular and highly flexible software package, which has been developed within the Clean Sky 2 FURADO project. In the first part of the publication, an introduction to the tool chain and the applied methods is given and subsequently, the results concerning the design optimization of a selected rotor blade-sleeve section are illustrated. The modules of the tool chain comprise state of the art software regarding computer aided design (CAD), mesh generation and numerical flow simulation. Concerning the optimization approach, a multi-objective genetic algorithm is employed to cover a wide range of the design space and to allow for the differentiation of the objective functions. Further, the gradual development of the Pareto-frontier can be observed and the derived geometry designs are thoroughly investigated.
