| Abstract: |
| According to domestic and foreign research progress of additive manufacturing （AM） technology in liquid rocket engine， rocket engine manufacturing process， methods， process standards and materials were summarized， as well as application of AM in liquid rocket engine， such as thrust chamber， turbine pumps， valves， general assembly components and the whole machine. Meanwhile， the development direction of AM technology in the field of liquid rocket engine was also predicted. It is pointed out that in the field of liquid rocket engine， AM should be carried out more comprehensive and systematic research on application level， engine structure design methods combined with AM characteristics， new manufacturing technology， manufacturing process standards， new materials and construction of material performance database， so as to meet major challenges in future aerospace field. |
