Scenarios

With the increasing use of aircraft, the importance of aviation safety is undeniable. As core components of aircraft, aircraft engines operate under high temperatures, pressures, loads, and speeds for extended periods of time. Failures such as turbine blade damage and combustion chamber cracks are common, directly impacting flight safety. Using borescopes to promptly detect internal engine damage, enabling precise measurement and accurate assessment, is crucial to aviation safety.
 
Key engine components, such as compressor and turbine discs, blades, and combustion chambers, are difficult to disassemble and offer limited accessibility. Inspection and monitoring of these components is typically performed through borescope testing. This more intuitive method, performed using a borescope (industrial endoscope), eliminates the need for contact with the target object, causing no damage or destruction, and requiring no cracking or disassembly. Therefore, it has become a key industrial non-destructive testing technology, particularly in civil aviation and military aerospace engine testing.
 
Using borescope technology (industrial endoscopes) for visual inspection, it is possible to enter the engine through the observation hole without disassembling the engine and extract images around the characteristic points of damage on aircraft engine blades. While obtaining clear borescope images of the damaged area, the 3D measurement industrial endoscope can also measure the depth and size of the defect. The measurement and diagnosis results are reliable and can be professionally analyzed by professionals, greatly improving diagnostic efficiency.
 
Coantec Ltd. is a high-tech enterprise specializing in the research and development, production, sales and technical services of industrial endoscopes. The company's independently developed and produced three-dimensional measurement products such as the C65 series and C68 series of borescopes (industrial endoscopes) have broken the long-term technology monopoly of foreign countries and have been applied in the field of borescope inspection in the aerospace industry and have been recognized by many customers.
 
The Coantec Ltd. C65 and C68 series not only intuitively display real-world aircraft engine internal inspection images but also enable high-precision 3D measurement. This high-precision 3D measurement technology is based on the principle of parallax and utilizes imaging equipment to capture two images of the object being measured from different positions. By calculating the positional deviation between corresponding points in the images, the 3D geometric information of the object is obtained. This system can measure defects in various modes, including length, depth, point-to-line, multi-line segment, area, and depth profile. Stored measurement images can be repeatedly measured, and independent re-measurement software, running on a computer with a fully identical interface to the local machine, allows for repeated measurement of stored images. During measurement, a 3D coordinate graph can be displayed with full-scale rotation, movement, and magnification capabilities, and precise measurement results can be displayed directly on the screen. Furthermore, this 3D measurement system can measure the depth of damage, such as ablation on the leading edge of turbine blades or guide vanes, as well as quickly and accurately measure the area, side length, and vertex angle of missing material at the tip of turbine blades.
