摘要:

叶片作为航空发动机的重要组成部分,其损伤与维修对飞机运行安全、运营成本具有重要影响。为提高维修质量和效率,国内外学者对叶片维修进行了诸多理论和工艺方法研究。为进一步分析损伤叶片的维修过程,总结了风扇叶片、压气机叶片、涡轮叶片、整体叶盘叶片的损伤类型与原因,详细分析了相应的维修技术路线。原位维修研究薄弱,重点说明了原位维修相关技术与装备、相关的优化方法及新技术的应用。最后,对航空发动机叶片维修领域的研究及发展方向进行了展望,为后续从事该方面研究的人员提供参考及借鉴。

Abstract:

As an important part of aero engine, blade damage and maintenance have an important impact on aircraft operation safety and operating cost. To improve the maintenance quality and efficiency, scholars at home and abroad have carried out considerable theoretical and technological research on blade maintenance. To further analyze the maintenance process of damaged blades, firstly, the damage types and causes of fan blades, compressor blades, turbine blades and integral disk blades were summarized, and the maintenance technical routes under different damage conditions were analyzed in detail. The research field of in situ maintenance is weak. Therefore, the related technology and equipment of in situ maintenance are explained in detail, as well as the related optimization method and the application of new technology. Finally, the research and development direction of aero engine blade maintenance are prospected, which can provide reference for future researchers in this field.

Key words: aero engine, blades, damage, repair, in situ maintenance
