国外航空发动机薄膜热电偶技术发展研究

摘要

The performance and technical characteristics for thin-film thermocouple were analysed.The method of sensitive film making,technologic method,quality control for thin-film thermocouple,and application and development of new technology were expatiated.The investigation results at home and abroad demonstrate that the advanced thin-film thermocouple technology can endure a hostile environment for aeroengine testing.It is a perfect method to successfully solve the surface temperature measurement for aeroengine blade and vane.%分析了薄膜热电偶的性能和技术特点,阐述了敏感膜的制作方法、薄膜热电偶工艺方法和质量控制,以及有关新技术的应用与发展。国内外研究结果表明：先进的薄膜热电偶能够承受恶劣的试验环境,是成功解决航空发动机涡轮叶片表面温度测量的理想方法。
