Among them, the pipeline endoscope and medical endoscope have played a very important role in it. At present, the endoscope technology has been very mature in our country and plays an important role in the aerospace field. Industrial endoscopy inspection is the area that the naked eye can not directly access to gold, which belongs to the visual inspection method in the non-destructive inspection industry, and it can not disassemble the mechanical parts.
                  

飞机检查和维修中都需要应用到工业内窥镜。据维护数据统计，大约90%的发动机非例行更换都与内窥镜检查结果直接相关。作为惟一一种在航线维护中能够不分解发动机而了解其内部状况的检查手段。内窥镜检查对于安全和效益两方面均有重要意义和价值：

Industrial endoscopes are needed in aircraft inspection and maintenance. According to the statistics of maintenance data, about 90% of non routine engine replacement is directly related to the results of endoscopy. As the only way to understand the internal condition of the engine without breaking down the engine in the course of maintenance. Endoscopy is of great significance and value for both safety and benefit

一是直观准确且简单易行，并能够尽早发现发动机内部部件的损伤，很大地有利于将安全隐患排除在萌芽阶段。

First, it is intuitive, accurate and easy to operate, and can find the damage of internal parts of the engine as soon as possible, which is very helpful to eliminate the potential safety hazard in the embryonic stage.

二是内窥镜检查避免了分解发动机和相应的发动机拆换、运输等费用以及不必要的飞机停运损失，节省维修成本。

Second, endoscopy can avoid the cost of engine decomposition, engine replacement and transportation, as well as unnecessary aircraft outage losses, and save maintenance costs.
