Application of Enhanced Visual Inspection in Aircraft Maintenance
-
摘要: 定期维护与检查是发现结构损伤并予以修理的基础。目视检查是飞机结构维护中最常用的检查方法之一。在分析研究国外参考文献和研究成果的基础上, 重点介绍了美国和欧洲近来投入使用的两种增强目视检查方法的基本概念、原理、系统组成、技术特点及应用范围。增强目视检查对结构表面形貌改变非常敏感, 包括表面裂纹、腐蚀凸起、冲击凹坑或其它异常情况, 检查速度快、简单方便, 可以避免飞机因为长时间停场造成的经济损失, 对保障飞机结构的安全性具有重要作用。Abstract: Scheduled maintenance and inspection are the foundation of finding of structural damage with related repair. Based on the analysis of foreign literatures, two enhanced visual inspections which were used in USA and Europe in recent years were introduced, focusing on the basic concept, principle, construction, technical characteristic, and applications. The enhanced visual inspections are sensitive to the shape change of structural surface, including surface crack, corrosion pillowing, impact dent and other abnormal conditions. The methods are fast and easy to used, which can both avoid economic loss due to long time stop, and be important significance to the safety of aircraft structure.
