Delta Air Lines uses the MAXOS non-contact measurement system from NVision

Delta Air Lines uses the MAXOS non-contact measurement system from NVision in its contract maintenance operations to achieve the highest possible accuracy in overhauling turbine blades and vanes. The traditional method of measuring blades and vanes to determine the level of repair required and to inspect subsequent repairs involves a series of manual measurements. “We have substantially improved on the traditional approach by using the MAXOS to provide consistent and repeatable measurements on parts with complex geometries and shiny finishes,” said Cameron Leonard, Special Projects Coordinator for Delta Air Lines.

Delta’s contract maintenance operation performs work on Delta planes as well as planes owned by other airlines and leasing groups. One of the most important maintenance operations is repairing blades and vanes at the heart of jet engines. Manuals provide numbers for critical dimensions on these parts such as the chord, axial chord and root. Maintenance staff measure parts and determine whether or not they meet the specifications. If they don’t, the part is repaired by building up the geometry with a welder, then machining it back to the original specifications and measuring it again.
