우리나라 항공우주분야 기술 동향 탐색: 한국항공우주연구원 사례로 = Exploration of Technological Trends in the Aerospace Field in Korea

다국어 초록 (Multilingual Abstract)

The purpose of this study is to explore technology trends in the aerospace field in Korea. To this end, domestic patents applied by the Korea Aerospace Research Institute were collected and topic modeling analysis was performed. As a result of the study, research topics in the aerospace field in Korea were largely identified as 15 technologies. Of the 15 technologies derived, 9 were common to the space sector, 2 to the aviation sector, and 4 to the aerospace sector. From the research results, it can be seen that Korea's aerospace research has mainly focused on space technology. In the case of space technology, based on the technology classification system of the National Key Space Technology Development Roadmap 2.0 (draft), research has been conducted on satellite payload technology, satellite main body technology, and launch vehicle engine technology. On the other hand, it was found that technologies for launch vehicle body and space observation and exploration were not appearing.
