| 摘 要： | 多学科设计优化（MDO）是为实现复杂产品设计方法升级换代的最佳技术途径。针对先进航空发动机设计面临的各学科间耦合关系复杂、指标冲突严重等困难,按零件、部件和总体方案设计３个阶段对MDO的各项关键技术开展了研究、开发及应用工作,提出了基于MDO技术的航空发动机一体化设计方法。给出的５个工程应用实例表明,该方法与传统设计方法相比,能大幅提高航空发动机设计水平,具有广泛的工程应用前景。

| 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. |
