| Abstract: | A survey on the techniques of intelligent Damage-Mitigating (DM) and Life-Extending (LE) control for Reusable Liquid-propellant Rocket Engines (RLRE) was presented. Firstly, the fundamental concepts and principles on DM and LE control were clarified. Then, the key technologies including system modeling and analysis, damage modeling and estimation, and techniques on design and realization of the DM controller and LE control algorithms were analysed in details. The key technology problems and trend were also indicated. |
