The initial geometry of the optimization will be the NASA rotor 37, a test compressor that was extensively studied. From experimental data available in the literature, the CFD code used in the optimization process will be validated as well as the procedure used to obtain mechanical responses. Then, the optimization process will be conducted using MINAMO, a multi-disciplinary design optimization tool of the applied research center Cenaero. This platform is strongly based on surrogate models.The design space of the optimization being defined by the coordinates of the blade's control points, an initial design of experiments will be built, exploring different geometries. For all the geometries, different mass flows and inlet profiles will be tested to extract enough information about each blade. Several optimizations will be conducted under different aero-mechanical constraints in order to evaluate the possible improvements and the impact of the constraints used. ER -
