As we all know, aircraft safety is an important item of non-destructive testing of aviation systems. Every time an aircraft takes off, it needs to be carefully inspected and tested to ensure its flight safety. Among them, the aerial video borescope system has made a great contribution. At present, the aerial video endoscope system technology is very mature in China, and it plays an important role in the aerospace field.
Next, we will introduce the commonly used endoscopes in aircraft inspections. The aerial video endoscope system is mainly used to inspect the working cavity of the aircraft engine, the surface of the welding seam, the surface of the duct, the blades of the aircraft, the turbine, the combustion chamber, etc.; and the engine cylinders, fuel pipes, hydraulic components, and nozzle components are all under quality control and maintenance. An indispensable testing tool in the inspection.
Generally, pipe endoscopes and straight endoscopes are mainly used. Industrial endoscopy is an area that cannot be directly accessed by the naked eye. It is a visual inspection method in the non-destructive testing industry, which can disassemble mechanical parts. The scope of endoscopy is very wide. The staff can quickly and easily use the endoscope to inspect the interior of the aircraft components. Especially those parts with small openings and long cracks and corrosion damage. It can also check for damage to the engine’s turbine blades, combustion chamber and the inner wall of the outer frame of the landing gear shock strut.
Advantages of Aviation video borescope system:
1, It is intuitive, accurate and simple, and can detect the damage of the internal components of the engine as early as possible, which is greatly beneficial to exclude safety hazards in the bud stage;
2, the endoscopy avoids the decomposition of the engine and the corresponding engine replacement, transportation, and other costs as well as unnecessary aircraft outage losses, saving maintenance costs.
Of course, the visual inspection also has its limitations. In addition to the cleaning work required for the side surface, cracks with a width of less than 0.01 mm are easily overlooked, and a tighter instrument is required for final confirmation. According to maintenance statistics, approximately 90% of engine non-routine replacements are directly related to endoscopy results. As the only means of inspection that can understand the internal conditions of the engine without decomposing the engine during route maintenance.
