Airbus R&D groups take delivery of laser ultrasound system

LUCIE, a noncontact, non-destructive, laser-ultrasound machine, will be tested on a composite fuselage section at Technocampus in France to determine its production feasibility.

On Oct. 20, Technocampus (Pays de la Loir region, France), the R&D teams of Airbus Nantes, EADS Innovation Works (IW) and Ecole des Mines, took delivery of LUCIE, a noncontact, non-destructive, laser-ultrasound machine that will be used to detect sub-surface flaws in composite aerostructures.

This machine, an iPLUS III developed and manufactured by iPhoton (Ft. Worth, Texas) but supplied to Technocampus via Tecnatom (Madrid, Spain), will allow researchers to demonstrate the advantages of the laser-ultrasonic technology relative to classic ultrasonic technology. The non-destructive testing capabilities of LUCIE will be evaluated in the next months on a nose fuselage demonstrator and other structures.

Under current composite inspection technology using ultrasound, inspection is possible only by direct contact or through a coupling agent. Usually, the part is immersed in a water tank or sprayed with water jets. Since 2007, Airbus Nantes has developed, with help from EADS, a laser-based inspection technology used with an articulated arm equipped with laser beams to generate ultrasonic waves without contact. The flexibility in movements and control of the technology is especially adapted to the inspection of composite parts of large dimension and with complex geometries, that could be applied tomorrow to future programs such as the Airbus A320neo.

The inaugration of LUCIE was celebrated in presence of Jany Gueret, president of GIP Technocampus; Gilles Cohenca, industrial architect R&T Airbus; Didier Guedra Degeorges, vice-president d’EADS Innovation Works; and Michel Bacou, director business relationship, Ecole des Mines de Nantes.

Aircraft Visual Inspection

Figure: Boeing 777 aircraft Commercial aircrafts are frequently inspected visually. There is a primary inspection called "walk around check" both in the line and the base, transit checks, daily check, weekly check, A check, B check etc… Line is the more about the quick checks while aircraft is in the park or in between flights. Base is mostly the hanger, where hard checks, repairs take place. A qualified engineer walk around the aircraft and inspect structural items visually. Engine is also checked during the walk around checks. There engineer watches for oil leaks, structural damages in the engine, inlet of the engine for composite parts fixtures to the structure, fan/first stages of the compressor, last stages of the turbine for deterioration or damages , or any unusual changes of the engine. In this example shows how, engineer/Pilot carry on a walk around inspection of a Boeing 777 aircraft. Figure: Walk around inspection of a Boeing 777 1. Left Mid Fuselage...

Eddy current Theory

Eddy current theory is based on electromagnetic induction. That means, a variable magnetic field can induce an electric current on a conductor which is separate to the source of the magnetic field, and also vice versa, which is an electric current generates a magnetic field. Similar theory is used for the magnetic particles inspection as well. Electromagnetic induction is used in many applications such as, Transformers, Electric motors, Generators, etc... In the field of Non destructive testing (NDT), we manipulate with this theory which I mentioned above, and try to find surface defects or/and shallow internal defects of ferromagnetic materials.

Magnetic Particle Inspection

Magnetic particle test is one of the common NDT methods. As you can see, this has to do something with magnets. For a starter, it is better to remember little bit about magnets before understanding this method. Magnet is a material produces a magnetic field. They have two poles which are known as North, and South. Opposite poles (N+S) attracts but same poles such as N+N or S+S repels. Figure: A magnetic field, created by iron dust Magnetic field is invisible. Any ferromagnetic material or another magnet responds to a magnetic field. Ferromagnetic materials are materials which magnetized either by another magnet or an electric field.
