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.
                  

飛機檢查和維修中都需要應用到工業內窺鏡。據維護數據統計，大約90%的發動機非例行更換都與內窺鏡檢查結果直接相關。作為惟一一種在航線維護中能夠不分解發動機而了解其內部狀況的檢查手段。內窺鏡檢查對于和效益兩方面均有重要意義和價值：

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

一是直觀準確且簡單易行，并能夠盡早發現發動機內部部件的損傷，很大地有利于將隱患排除在萌芽階段。

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.

二是內窺鏡檢查避免了分解發動機和相應的發動機拆換、運輸等費用以及不必要的飛機停運損失，節省維修成本。

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