Measuring Turbine Blades

Measuring a turbine blade with 4D InSpec is an easy matter. You may inspect a wide range of blade elements and features with high versatility:

  • Deformations of blade edges
  • Surface defects
  • Defects between blades
  • Radius of curvature


Blade Edge Measurements

Grooved focus aids help you hold 4D InSpec in alignment with a turbine blade edge. From a measurement, you can quantify dents and deflections from damage.

Surface Defects

Automated feature analysis can be used to isolate and quantify different kinds of defects found in a measurement.

Defects Between Blades

Use a fold mirror to measure surfaces between closely placed blades.

Radius of curvature

The photo below shows an area of curvature, and a measurement that calculates the radius of curvature in the joint.
