Application of industrial endoscope in engine hole detection
Engine hole inspection (borescope inspection) is an important means of monitoring the state of aircraft engines. It uses industrial endoscopes to inspect the internal structure of the engine and detect damage in time to evaluate the overall performance of the engine. To put it figuratively, it is equivalent to doing a "gastroscopy" inspection of an aircraft engine. According to statistics, more than 90% of the dismantled engines were dismantled according to the fault conditions detected by the borehole probe.
The main part of the internal structure of the engine is also the key part of the borehole inspection. From front to back are the low-pressure compressor, high-pressure compressor, combustion chamber, high-pressure turbine and low-pressure turbine. For general airlines, the inspection of the internal structure of the engine can only be carried out by special means without disassembling the engine. This special method is to use industrial endoscopes to perform non-destructive testing on the internal structure of the engine, which is what we call hole detection.
Using the portable video industrial endoscope, the damage inside the engine can be found, which provides favorable support information for the replacement and monitoring of the engine. With the continuous progress of video industrial endoscope technology, the measurement of damage has developed from shadow measurement to more advanced stereo measurement, which greatly improves the measurement accuracy; the probe over-temperature alarm function has been added to prevent the probe from being damaged by high temperature; There is a Chinese operation menu suitable for domestic use. I believe that more advanced equipment will replace it in the future to improve the maintenance level of the engine.
