Speech Title:
Key Technologies of Advanced Liquid Rocket Engines

Abstract:
The liquid rocket engine is the core component of launch vehicles and determines the ability to enter space. With the rapid development of large-scale space infrastructure and the aerospace industry, higher requirements are imposed on liquid propulsion technology. This lecture provides a systematic overview of the major research directions of advanced liquid rocket engines. Beginning with an overview of Chinese liquid rocket engines, the speech addresses representative technical characteristics of advanced liquid rocket engines, including rapid dynamic processes, extreme operating environments, high requirements on manufacturing, and difficulties in fault diagnosis. To overcome these challenges, several research directions have been identified. The speech introduces the latest progress in detail and outlines prospects for future advancement, covering the control of system dynamic characteristics, the design of lightweight structures, the control of combustion stability, the design of high-power-density turbopumps, technologies of reusable engines, as well as fault diagnosis and health management.
