Abstract：Aiming at reliability of pipeline connection and seal of reusable liquid rocket engine, combining with the development of a liquid rocket engine, this paper compares and analyzes the reliability requirements of one-time use engine and reusable engine from the aspects of mission profile, environment profile, life profile, functional requirements and structure change. Based on the analysis of the present situation of the reliability research of the pipeline connection and seal of the reused engine, this paper points out the deficiency existing at present, gives the reliability design and reliability verification direction of the pipeline connection and seal, and puts forward the technical roadmap of the pipeline connection and seal reliability. It can provide reference and inspiration for future general planning and development of reusable liquid rocket engine .
