YUSHI PM10 Immersion Ultrasonic Testing for Aircraft Turbine Blades

In this video demonstration, the YUSHI PM10 Ultrasonic Thickness Measurement Workstation performs water immersion testing on aircraft turbine blades – one of the most demanding applications in aerospace NDT.

The PM10 is a portable ultrasonic thickness gauge that combines a 13-inch HD touchscreen, full imaging functionality, encoder support, and interactive detection. With 1μm resolution and support for probes up to 75MHz, it delivers lab-grade precision for complex geometries like curved turbine blades. The immersion method ensures superior coupling stability and signal clarity compared to conventional contact methods, making it ideal for both production quality control and MRO inspections in the aviation industry.

Why Water Immersion for Aircraft Blades?

Aircraft turbine blades feature complex curved surfaces and unique grain structures that make conventional contact ultrasonic testing challenging. The water immersion method addresses these challenges by providing a consistent coupling medium between the probe and the workpiece, eliminating variables caused by surface roughness or operator technique.

The result is faster, more accurate, and more repeatable measurements – critical factors in aerospace manufacturing and maintenance where precision is non-negotiable.

Typical Applications:

• Aerospace turbine blade wall thickness measurement

• Curved surface NDT for aviation components

• Corrosion mapping and wall thickness scanning

• Multi-layer material inspection
