摘要
为发掘航空发动机领域的研究热点和前沿技术,本文采用S曲线方法,选取PW公司的专利文献为研究对象,对PW公司成立至今申请的专利文献进行统计分析。通过专利申请动向和专利国别分布分析识别了宏观专利布局;通过专利技术领域和核心专利分析总结了研究热点;通过专利成熟度和专利申请趋势分析识别了前沿技术,预测了未来发展趋势。研究结果表明,航空发动机技术处于快速发展的成长期,研究热点集中在针对活塞式发动机和燃气涡轮发动机的结构优化,前沿技术集中在针对燃气涡轮发动机的持续改进和新概念发动机的技术创新。
In order to explore the research hotspots and cutting-edge technologies in aero-engine,this paper uses the S-curve method,and makes statistical analysis on patents applied by Pratt Whitney since its establishment.The macro patent layout is identified by analyzing patent application trend and patent country distribution.The research hotspots are summarized through the analysis of patent technology fields and core patents.Through the analysis of patent maturity and patent application trend,the frontier technology is identified and the future development trend is predicted.The research results show that aero-engine technology is in the growth stage of rapid development,the research focus is on the structural optimization of piston engine and gas turbine engine,and the cutting-edge technology is focused on the continuous improvement of gas turbine engine and the technological innovation of new concept engine.
