Abstract:
The elastoplasticity sealing mechanisms of elastic metal seal (EMS) are discussed. The development history for EMS in some cryogenic liquid rocket engines all over the world is reviewed. According to the working features of high-pressure staged combustion LOX/kerosene engine, the sealing characteristics of Э seal, K seal, dish seal and soft metal seal used in the pipeline of high-pressure staged combustion rocket engine are analyzed. Considering the structural design, material selection, manufacturing technique and pre-tightening load control, some technical points which determine the performance of the EMS are proposed. Aiming at the theoretical research and engineering application status of Chinese EMS in high-pressure staged combustion rocket engine, some suggestions related to the study of the EMS in the enhancement of the fundamental research, improvement of the design method and deflection control of pre-tightening force are proposed.
