3D Metrology Services – Aerospace – Defect Detection on Turbine Blade

The 3D metrology systems we build utilize high-resolution 3D scans to automatically detect AND measure defects in some of the most complex Aerospace components.

Below is an example of automated defect detection and defect measurement on an aeroengine turbine blade. The 3D measurements and defect inspection of this component were completed using our RSH-M10 Robotic Metrology System with our Defect Detection Process Solution (DDPS).

To learn more about our automated defect detection and measurement solution and how to apply it to the your components, please contact our 3D Metrology Sales team.

APPLICATION DETAILS

  • Component – Engine Component
  • Material – Nickel Alloy
  • Metrology Services:
    • Automated defect detection
    • Automated defect measurement
    • Automated report generation containing defect count, sizes, and location

Physical Part

A close-up, grayscale image shows a single, metallic turbine blade resting on a dark, textured surface. The blade is elongated with a curved leading edge and a straight trailing edge. Its surface exhibits subtle variations in light and shadow, suggesting a smooth, polished finish and possibly some wear or imperfections. The base of the blade, where it would attach to a rotor, is visible as a thicker, rectangular section.

High-Density Point Cloud Capture

Automated Detection and Measurement of Defects

The image displays a system for automated defect identification and quantification. On the left, a 3D point cloud visualization shows surface irregularities, with red indicating higher elevations or defects and green indicating lower elevations. To the right, a table lists the identified defects with their ID, dimensions (length, width, depth, height), position (X, Y coordinates), and confidence score. Below the table, a processed image highlights four distinct defects, labeled 1 through 4, corresponding to the data in the table. A red arrow connects the 3D point cloud to the processed image, illustrating the workflow from data acquisition to defect detection and analysis.

Automated Report Generation with Count, Sizes, Locations

The image displays a three-panel report detailing a 3D scan analysis. The left panel shows a 3D model of a cylindrical object with several red and green markers, indicating points of interest or measurement locations. Below the model, a table provides details such as 'Part Number', 'Sample Location', 'Number of Anomalies Detected', and 'Confidence Percentage'. The central panel presents a 'SUMMARY' table with columns for 'Serial No.', 'Length (m)', 'Width (m)', 'Depth (m)', 'Radius (m)', and 'Confidence (%)', listing data for four different entries. The right panel contains two sections, each with a colored heatmap-like image and a corresponding table. These sections are labeled 'SURFACE PLOT' and list parameters like 'Min (µm)', 'Max (µm)', 'Average (µm)', 'Std Dev (µm)', 'Range (µm)', and 'Confidence (µm)'. The heatmaps likely visualize surface deviations or irregularities.
