Abstract
Multidisciplinary design optimization (MDO) is regarded as the most hopeful upgrade of current methodology for complex system design. In order to overcome the difficulties in advanced aero-engine design, such as complex coupling relations and serious conflicts between different disciplines, the research, development and application of key technologies of MDO have been carried out in three phases: part design, component design and whole engine preliminary design. And a MDO-based integrative aero-engine design method is presented. Five examples of engineering applications are given to demonstrate that the proposed method can improve aero-engine design ability very much comparing with the traditional method, and is prospective to be applied widely to engineering field.
