Guarding the “Heart” of Gas Turbines: T2 Assists in Nondestructive Inspection of Gas Turbine Blades

Gas turbines, as a common type of heat engine, play an important role in aviation propulsion, ship power, offshore platforms, thermal power generation, oil and gas transportation, and other fields. Their internal blades operate under high-temperature and high-pressure conditions for long periods and are prone to defects such as cracks, burning, and wear. Traditional inspection methods often require disassembling the engine, resulting in high costs and long turnaround times. With industrial borescopes, technicians can reach deep inside through reserved inspection ports and complete inspection and blade counting without dismantling the equipment.

At a gas turbine site, the customer used the kunscope T2 high-definition industrial borescope, inserting the probe through the unit's reserved inspection ports into the combustion chamber and turbine section to inspect and count the internal blades one by one. During the inspection, on-site personnel used the T2's high-definition imaging capability to clearly observe the surface condition of the blades, and used the probe's steering function to sweep through the blade passages one by one, ensuring no omissions and no repetitions.

The kunscope T2 High-Definition Industrial Borescope

Ultra-Clear, High-Brightness Imaging:
The T2 is equipped with a 5.5-inch high-definition LCD screen, whose brightness is increased by more than 60% compared with conventional products. The camera supports gain adjustment, which can effectively suppress metal highlights, reflections, and glare. In metal surface scenarios such as gas turbine blade inspection, it can more clearly identify defects such as cracks and burning.

Interchangeable Lenses and Broad Compatibility — Core Advantages of the T2:
The system is compatible with a wide range of probe specifications from φ0.85 mm to φ8.0 mm, and supports interchangeable φ3.9 mm and φ6.0 mm direct/side-view lenses, covering various optical configurations such as macro, near focus, wide angle, medium focus, and far focus. This means that when facing different gas turbine inspection port sizes and internal passage structures, on-site personnel can flexibly select the appropriate probe to complete the inspection.

Flexible Steering Capability — Equally Critical:
Relying on self-developed transmission technology, the T2 can achieve 360° full-area mechanical steering over long distances, with a steering angle of up to 140°, enabling precise positioning and observation of targets within the complex internal cavities of gas turbines. Combined with a high-definition long-distance image transmission system, it can maintain clear imaging even at relatively deep positions.
