Multidisciplinary design optimization is a methodology to design complex systems and their subsystems by fully exploring and utilizing the interaction mechanism of the system. It is the most active research field in the current complex systems engineering. The multidisciplinary nature of the design of large thrust liquid oxygen / kerosene gas-to-fuel cycle engines presents new challenges to the traditional design methods. Based on the analysis of the multidisciplinary nature of the design of liquid oxygen / kerosene engines, The key problems in the application of MDO technology in kerosene engine design are summarized. The research progress in relevant fields at home and abroad are reviewed. The prospect of applying MDO in the design of large thrust liquid oxygen / kerosene fuel cycle engines is expounded.
