摘要
提出了军用航空发动机预测与健康管理（prognostics and health management,简称PHM）系统的发展策略和关键技术.首先回顾了国外航空发动机PHM技术的发展历史,简要分析了各个阶段具有代表性的技术特点;其次,详细论述了航空发动机PHM技术发展应当妥善处理的关系和重要问题,主要包括PHM技术发展与空军军事需求、PHM技术发展与技术成熟度体系、立足三代机平台发展PHM技术、在发动机全寿命管理体系引入PHM系统、建议的航空发动机PHM功能和结构等;接着,结合国内技术发展水平,给出了应当重点优先发展关键技术的建议;最后,简要总结了制约国内PHM技术发展的因素,展望了瞄准的技术发展目标.
The development strategy and key prognostics health management（PHM） technologies for military aero-engine in China were proposed.First,the development history and corresponding representative features of PHM was briefly reviewed.Then,several key relationships and important issues in PHM technology development worth emphasizing were minutely analyzed,which include the relationship between PHM technology development and the air force military requirements,the relationship between PHM technology development and the technology readiness level,developing PHM technology based on the third generation aircraft platform,introducing PHM into aero-engine full-life management system,and the proposed PHM architecture and composed functions for China air force,etc.After that,the key technologies which should be focused on with high priority in China were proposed.Finally,the factors that constrain the domestic developments of China military PHM technology and the aimed technology developing targets are shortly concluded.
