The present paper compares four different optimization strategies for decoupled optimization in the context of preliminary core engine design for aero engines. An optimization with the AAO (All-At-Once) approach is performed as a baseline and compared against the performance and results of three cascaded optimization strategies: CO (Collaborative Optimization), BLISS 2000 (Bi-Level Integrated System Synthesis) and ISOC (Interface Segmentation Optimization Concept). The optimization problem is

The results are assessed with respect to typical requirements for multidisciplinary core engine design. The impact of the used optimization strategy on the performance of the optimization concept is investigated and discussed.
