Can Ordinary Industrial Videoscopes Be Used for Aircraft Engine Inspection?

In the routine maintenance of aircraft engines, industrial videoscopes—often referred to as borescopes—are indispensable diagnostic tools. They allow non-invasive visual inspection of critical internal components such as turbine blades, combustor chambers, and compressor sections, significantly reducing the need for engine disassembly. This capability is vital for ensuring flight safety, minimizing aircraft downtime, and improving maintenance efficiency.

However, given the extreme operating conditions and stringent inspection standards in aviation, can general-purpose industrial videoscopes meet these demanding requirements? The answer is a definitive no.



An aircraft engine borescope inspection is far more than a simple "visual check"—it requires the capability to see clearly, measure accurately, and diagnose correctly. This imposes extremely high demands on the equipment’s optical system, measurement precision, image processing capability, and intelligent assistance functions. For instance, the system must not only detect the presence of cracks on blades, but also precisely measure their depth, area, and orientation, and ideally, intelligently classify defect types and generate structured analysis reports. Conventional industrial videoscopes are unable to meet this comprehensive set of stringent requirements.

True aircraft engine borescopes, such as Coantec's X5 series, represent the cutting edge of current remote visual inspection (RVI) technology. Taking the latest-generation X55 as an example, it offers the following key advantages:
