Reliability Enhancement Technology of Turbine End Shaft Seal in A Liquid Rocket Engine
Based on engine structure and sealing principles,a shaft rotation processing method is proposed to address the issue of excessive leakage of turbine end shaft seal after testing of a type of liquid rocket engine,which leads to the inability to deliver the engine normally.The feasibility of the technique is analyzed,and craft equipment is designed and manufactured to obtain process parameters for improving sealing performance by process testing.The experimental results show that after engine process testing,it can improve the fitting state of the turbine end shaft seal,reduce seal leakage,upgrade the reliability and reusability without decomposing the engine.
