Military Aircraft Parts Reverse Engineered Using 3D Laser Scanning, Structured Light Scanning & GD&T Best Practices
3D Engineering Solutions employed 3D laser scanning, structured light scanning and Geometric Dimensioning and Tolerancing (GD&T) best practices to reverse engineer components for military aircraft, including parts for large helicopters and Harrier jump jets recently sold by Britain to the U.S. Because the CAD models and prints for these parts are not available, 3D Engineering digitized each component, determined the materials, finishes and coatings, and then created new CAD models and prints to be used by government suppliers in recreating each piece. 3D laser scanning was employed to digitize the larger parts while structured light scanning was used to capture the smaller, detailed components.
"The difficulty in these types of projects comes in discerning the original design intent of the component. This is done by studying how the parts interact with the overall system and applying proper dimensioning and geometric dimensioning and tolerancing (GD&T) that is appropriate for the design intent and to reduce the end cost of the components," said 3D Engineering Solutions Vice President of Operations Rob Glassburn, P.E. In all, 3D Engineering created over 200 prints for the helicopter and Harrier projects, comparing the scans they captured with the models they created numerous times.
3D Engineering Solutions is completing the prints of these wear item components at a time when Diminishing Manufacturing Sources and Material Shortages (DMSMS) pertaining to military aircraft is on the rise. "For various reasons, suppliers to our government are no longer able to provide key components to certain systems. Many of these components are wear items that need to be replaced on a frequent basis," said Glassburn. "When the prints for these parts aren't available, that's where we come in."
