A Dynamic Centered on Innovation

The most advanced non-destructive testing methods are used daily by Eurocopter – where state-of-the-art technology is harnessed to the group’s know-how.

Eurocopter has steadily enhanced its experience in non-destructive testing, and the group regularly develops new methods for detecting defects in the spheres of design, production, maintenance and repair.
The goal is clear: to guarantee the quality of manufactured parts by ensuring composite and metal structural parts, as well as dynamic components, are free of external or internal defects.
While every Eurocopter site has its specificities, which are directly linked to the production activities, the choice of equipment requiring major investment is made in a complementary way; and a harmonization policy is being implemented within the group to rationalize resources, problem solving, and research in this field.

State-of-the-Art Technology
Eurocopter is continuously investing in its nondestructive testing resources, and the group uses the very latest technology.
For example, automatic waterjet systems are used to inspect composite parts.
Ultrasonic immersion tank systems and digital radiography are also used respectively to inspect parts with an integral solid (monolithic) structure and to check sleeves and stars.
In addition, thermography and shearography are used to measure the surface deformation of components.

These techniques are used to detect tiny defects over very large surfaces without touching the examined part. Metal parts are checked using magnetic particle inspection equipment while a micro focus X-ray system with a long anode is used to check welding quality.
Finally, the traditional NDT methods (X-ray inspection, dye penetrant inspection, eddy currents, etc.) are also commonly used in Production.
This year, Eurocopter is set to invest in a microtomograph, which will be specifically used for research and non-destructive investigation.

A HIGH LEVEL OF SKILLS

Magnetic particle inspection equipment for ferromagnetic parts (gear assemblies and rotor shafts).

In addition to the non-destructive testing installations and equipment, which are monitored to ensure their performances comply with the criteria defined by the Design Office, the operators using these techniques must also be certified in accordance with the EN4179(1) European standard.
Three levels of certification exist, and Eurocopter holds the Level 3 certification for specialist operators, for all the most widely employed non-destructive testing techniques.

(1) European standard that stipulates the rules for the certification of NDT operators.
This document is technically accepted as the equivalent of the NAS 410 standard, the US standard certifying NDT operators
