多学科设计优化是一种通过充分探索和利用系统的相互作用机制来设计复杂系统及其子系统的方法论,是当前复杂系统工程设计中最活跃的研究领域。大推力液氧/煤油补燃循环发动机设计的多学科本质属性给传统的设计方法带来了新的挑战,在分析液氧/煤油发动机设计的多学科特征基础上,重点讨论了在液氧,煤油发动机设计中应用MDO技术的关键问题,综述了国内外相关领域的研究进展,阐明了在大推力液氧/煤油补燃循环发动机设计中应用MDO的前景。

Multidisciplinary design optimization through sufficient investigation, takes advantage of the （MDO） is a methodology, which has gone interaction mechanism to design the complex system and subsystems, and is most active research filed of complex system engineering design at present. The multidisciplinary essential attribute of designing high-thrust LOX/Kerosene combustion cycle liquid rocket engine brings a big challenge to the traditional design approaches. Based on the fully analysis of the multidisciplinary characteristics of LOX/Kerosene engine design, the key technologies which are essential to implement the MDO method in LOX/Kerosene engine are discussed. The research situations at home and abroad are summarized, which shows a bright.future of adopting MDO method to design the high-thrust LOX/Kerosene combustion cycle liquid rocket engine.
