基于SNA的航空发动机空中停车文献分析

Analysis on Literature of Aero-engine in Flight Shut-down Based on Social Network Analysis

由于发动机故障引起的空中停车存在高危险性和不确定性,必须做好防范和处置。在CNKI数据库中以“空中停车”关键词检索相关研究文献,应用SATI3.2软件对检索文献数据进行数据预处理,获取高频关键词并构建共词矩阵;应用Ucinet6.0软件对关键词进行社会网络分析和聚类分析。结果表明:航空发动机空中停车研究领域热点集中于管理、维修、人员及企业运营等方面;民用航空与军用航空在该领域的研究重点存在差异;非常规类飞机的空中停车受到关注,无人机空中停车研究将成为该领域的热点问题;军用飞机空中停车研究成果相比民用飞机存在一定差距,随着军用飞机适航工作的开展和推进,军用飞机空中停车研究将在该领域占据重要地位。

The in fight shut-down(IFSD)of the aero-engine caused by engine failure has high risk and uncertainty,so it is necessary to do a good job of prevention and disposal.Aiming at the problem of IFSD,the social network analysis(SNA)method is used to make a quantitative analysis of the research status of the aero-engine IFSD in China.In the CNKI database,IFSD is used as parallel keywords to search relevant research literature.The SATI3.2 software is used to preprocess the literature data to obtain the high-frequency keywords and construct the co-words matrix.The Ucinet6.0 software is used to conduct the social network analysis(SNA)and clustering analysis for key words.The results show that the hotpot of aero-engine IFSD research study focuses on the aspects of management,maintenance,staff and enterprise operation;the research emphasis of civil aviation and military aviation is different;the IFSD of unconventionality aircraft is focused,and unmanned aerial vehicle IFSD research becomes the hot issue of this field;the research results of military aircraft and civil aircraft IFSD are different,with the development and advance of military aircraft airworthiness,the IFSD of military aircraft will take up the important position of this field.
