Industrial endoscopes have many applications in the field of aerospace, aviation is mainly used in aircraft engine turbine blades, combustion chamber cracks, airframe structure framework to find the internal redundancy of the exclusion of all kinds of oil and liquid pipeline welding and other surface defects in the inner cavity and other detection, all kinds of pipeline weld surfaces, the surface of the catheter, and the engine's cylinders, fuel tubes, oil pressure components, nozzle components. Due to the complexity of the structure of the aviation engine, the routine maintenance and inspection cannot always be disassembled to find out the problem, which requires the endoscope to complete the regular inspection. It is also one of the most important tools in the daily maintenance and routine inspection of aircraft engines.

In the aerospace industry, it is mainly used in the research and development of rocket motors, manufacturing, assembly, welding seams inside the cavity of the arrow body, quality control such as checking sand entrapment in casting, burrs and staggered holes, as well as defect detection in key areas such as the flight navigation system.
