Engine failure is like the heart disease, and the in fight shut-down (IFSD) of the aero-engine is seen as a killer of the flight because of its high risk and uncertainty. We must do a good job of prevention and disposal. Aiming at the problem of IFSD, This paper uses the social network analysis method to make a quantitative analysis of the research status of the aero-engine IFSD in China. In the CNKI database, IFSD were used as parallel keywords to search relevant research literature. The SATI 3.2 software was used to preprocess the literature data to obtain high-frequency keywords and construct the confession matrix. Then, the Ucinet 6.0 software was used to conduct social density analysis, centrality analysis, condensate subgroup analysis and core-edge analysis on key words. Through quantitative analysis, the current research hotspot and frequency were extracted, the focus and development trend of subsequent research were predicted.
