The 13th Aviation Power and Gas Turbine Focus Conference & Exhibition (GTF 2026) took place from May 12 to 14 at the Shanghai World Expo Exhibition & Convention Center. Jointly organized by the Chinese Society of Power Engineering, the Chinese Society of Aeronautics and Astronautics, the Chinese Society of Theoretical and Applied Mechanics, and Decision Makers’ Think Tank, the event was held under the theme “Strengthening Industrial Chain Synergy, Building a Collaborative Innovation Ecosystem, and Seizing China’s Opportunities.” It drew more than 270 exhibitors from across the industry.
Often described as the “crown jewel of modern industry,” aero engines are characterized by extremely complex internal structures and long, narrow passageways, making inspection particularly challenging. The level of autonomy in non-destructive testing technologies is therefore closely linked to the safety and reliability of critical national aerospace equipment.
Coantec, the first company in China and the third globally to master interchangeable optoelectronic lens technology for industrial borescopes, showcased its C40, M40, X5, BLX, and CPT telescopic video inspection systems at the event. The company highlighted its latest advances in routine inspection, high-precision 3D measurement, AI-assisted defect detection, and specialized inspection solutions, continuing its push to advance domestic substitution and strengthen technological self-reliance in the sector.
Since its founding in 2012, Coantec has obtained more than 120 patents, including 39 invention patents. The company invests around 20% of its annual revenue in research and development, with cumulative R&D spending approaching RMB 70 million. These sustained investments have enabled Coantec to move from following industry standards to competing at parity, and in certain areas, emerging as a technological leader in industrial borescope solutions.
Five Key Exhibits Cover Applications Spanning Routine Inspection, Precision Measurement, and AI-Assisted Detection
C40 & M40 Series: Upgraded Industrial Borescopes for Complex Inspection Scenarios
The C40 series is equipped with a 720P HD imaging system and a 3.5-inch sunlight-readable display, delivering clear visuals even under strong lighting conditions. It features a rapid tube-change system that enables users to switch between different insertion probes within 20 seconds. Supporting probe diameters from 2 mm to 6 mm, a single unit can be adapted for multiple inspection scenarios, making it well suited for routine borescope inspections of aero engines and gas turbines.
The M40 series is an upgraded version of the C40, designed as a high-definition modular handheld industrial borescope. While retaining its portable form factor, it incorporates a larger industrial-grade touchscreen and a wider range of interchangeable modular probes and lens systems. These enhancements further improve operational efficiency and inspection adaptability, enabling effective visual inspection and diagnosis of complex internal structures.
X5 Series: High-Precision 3D Measurement Borescope for Quantitative Inspection
The X5 series is equipped with a high-precision 3D measurement system that supports a range of measurement functions, including point-to-point, point-to-line, point-to-surface, multi-segment length, and enclosed area calculations. With an accuracy of up to 0.01 mm, it upgrades defect inspection from qualitative observation to quantitative analysis.
The series features an electronically controlled probe replacement system, a fully laminated IPS HD touchscreen, and an optional laser illumination system. It has already been applied in the borescope inspection of multiple aero engine models, serving as a viable domestic alternative to imported equipment.
BLX Series: AI-Assisted Defect Recognition Industrial Borescopes
The BLX series is an AI-powered industrial borescope, first launched globally at the 2025 Control Exhibition in Germany and making its debut at a major aerospace exhibition in China with this event.
The system is equipped with a dedicated NPU processor, delivering 12 times the computing power of the previous generation. It supports AI-based defect recognition and voice interaction, enabling automatic identification of common engine defects such as cracks, corrosion, and foreign object debris. With a 5.5-inch touchscreen and a modular lens system, it significantly lowers the operational barrier while improving inspection efficiency.
CPT Series: Gas Turbine Peripheral Inspection Equipment
The CPT series is designed for inspection of confined spaces in gas turbine peripheral structures and large-scale equipment, including piping systems, combustion chamber casings, and exhaust assemblies.
It features an 8-inch HD display and a three-section carbon-fiber telescopic rod. The probe supports both axial and horizontal rotation, and the system offers photo capture, video recording, and playback functions. An optional audio module is also available, making it well suited for on-site maintenance and routine inspection tasks.
Exhibition Feedback and Industry Attention
During the exhibition, the Coantec booth attracted visitors from aero engine OEMs, gas turbine manufacturers, maintenance service providers, and research institutions for in-depth discussions.
The X5 series drew strong interest for its 3D measurement capabilities, while the BLX series received significant attention for its AI-based defect recognition and voice control features. On-site demonstrations were met with positive engagement and feedback.
Exhibition Review and Upcoming Events
GTF 2026 has now concluded. During the event, the company engaged with industry partners on the applications of industrial borescopes in aero engine and gas turbine inspection, as well as broader industry trends.
Looking ahead, Coantec will continue to advance innovation in non-destructive testing technologies to support the development of the aerospace and gas turbine industries.
The next stop is the 11th International Exhibition on Police Equipment and Anti-Terrorism Technology, held June 4–6 at the Beijing Exhibition Center, Booth B12115.
