Optimal structural design of compressor stage of aviation engine is considered. Structural optimization takes into account the blade shape and disk design. Minimization of mismatching between the blade shape in operating position and predefined aerodynamic blade shape and natural frequency detuning problem are discussed. Disk and joint weight minimization under certain constraints is investigated. Optimization criteria, constraints, parameterization and design models, design parameters are discussed. All results were obtained using finite element analysis program connected with the sequential quadratic programming (SQP) optimization procedure.
