Safeguarding Low-Altitude Safety: The "Eagle Eyes" of COANTEC Industrial borescopes

The low-altitude economy, as a national strategic emerging industry, is experiencing rapid development, with the commercialization of aircraft such as drones and eVTOL systems accelerating. Against this backdrop, the demand for aircraft safety assurance is increasingly prominent. Industrial borescopes, as a core tool of non-destructive testing (NDT), provide crucial technical support for the early identification of safety hazards due to their ability to perform precise inspections of internal structures.

Non-destructive testing has permeated the entire low-altitude economy industrial chain:

In the R&D stage, it assists in product design and process optimization;

In the production stage, it undertakes quality control of components and the entire aircraft;

In the operation and maintenance stage, it enables regular inspections and preventative maintenance.

From R&D to operation and maintenance, industrial borescopes have always been an indispensable and important technical means to ensure the safe development of the low-altitude economy.

Technical Challenges: Three Major Bottlenecks in Low-Altitude Inspection

1. Spatial Accessibility Limitations: Low-altitude aircraft adopt highly compact designs, with numerous millimeter-level cavities in critical areas such as engine pipes and composite material interlayers. Traditional inspection equipment, due to size limitations, cannot penetrate these narrow spaces, creating blind spots. 2. High Defect Identification Accuracy Requirements: Typical defects in aerospace aluminum alloy components, such as microcracks and composite material delamination, typically range in size from 0.1 to 0.5 mm. This necessitates micron-level resolution in the inspection equipment, placing extremely high demands on the imaging system's analytical capabilities.

3. Lack of Inspection Efficiency and Standards: Existing inspection processes heavily rely on operator experience, with a single comprehensive inspection taking 2-4 hours. Furthermore, the industry lacks unified defect judgment standards, leading to significant differences in inspection results between different institutions and impacting assessment consistency.

Coantec Industrial borescope Technological Breakthroughs

1. Replaceable Pipeline Technology: Coantec's replaceable pipeline technology overcomes traditional limitations, supporting rapid interchange of various pipeline specifications. When equipped with an ultra-fine probe, it can penetrate millimeter-level confined spaces such as engine fuel nozzles, addressing a wider range of inspection scenarios. This flexible configuration ensures both the ability to detect special structures and practicality for daily inspections, truly achieving multi-functionality.

2. High-Definition Imaging System: Coantec industrial borescopes are equipped with ultra-high-definition cameras and high-sensitivity sensors, delivering detailed images and rich details in various lighting conditions. Even in the confined spaces of a drone inspection environment, it can clearly display the internal structure of equipment and accurately capture minute defects.

3. Equipped with a high-precision 3D measurement system, significantly improving inspection efficiency. The Gu'antai Industrial borescope integrates a high-precision 3D measurement system, achieving rapid defect identification and accurate measurement through real-time point cloud data acquisition and AI intelligent processing. With a measurement accuracy of 0.01mm and an error control of ≤5%, it significantly reduces manual interpretation time, shortening the single-machine inspection cycle by 30%, effectively improving the overall efficiency of low-altitude aircraft inspection operations.

From December 12-14, 2025, Gu'antai Industrial borescope will showcase its new low-altitude economic non-destructive testing solution at the 8th Global Unmanned Systems Conference & 2025 Guangzhou International Low-Altitude Economy and Trade Expo. We cordially invite you to visit our booth B47-3 in Area A of the Guangzhou Pazhou Canton Fair Complex to explore the innovative applications and practical achievements of industrial borescopes in ensuring low-altitude safety!
