| 摘要: |
| 目前，飞行器的多学科设计优化（MDO）方法研究已经成为国际上航天领域的一个研究热点，但在我国，与MDO基础理论研究的迅速发展相比，MDO的工程应用研究相对滞后，甚至导致部分飞行器设计人员对于MDO理论的实用性产生质疑。本文结合我们近十多年来的研究工作，在分析MDO工程应用所面临困难的基础上，总结了MDO工程应用研究的关键技术，归纳了国际上MDO工程应用大致经历的三代研究概况，并以我们所完成的三个飞行器MDO实例来说明这三代研究各自的特点，最后对MDO工程应用研究的发展趋势进行了简要分析。 |

| Abstract: |
| Multidisciplinary Design Optimization (MDO) of flight vehicles is now a focus of international research in the aerospace field. The engineering application research of MDO, however, falls behind the fundamental theoretical research domestically, which sometimes even leads to the suspicion of the practicability of MDO. On the basis of our research on MDO in the past decade, the difficulties of the engineering application and the relevant key technologies of MDO were analyzed. The international research on engineering application of MDO can be approximately summarized into three stages, the characteristics of which were illustrated with three application examples in flight vehicle design implemented by our group. Finally, the future trends of the MDO engineering application were briefly analyzed. |
