PHOTOS: Airbus completes lightning strike tests on A350 XWB



Airbus has completed a number of important development milestones with its forthcoming A350 XWB over the past few months.

In March 2013, for example, the first A350 XWB emerged with its wings completed (click here for story and images), while its Rolls-Royce Trent XWB engines were installed in the same month too (click here for story and images).

Well, here’s another milestone for the much-awaited aircraft! Lightning strike testing has just been performed, completing a key required step in preparations for the maiden flight.

Check out an image on this page, with more on my Facebook page - click here to view the photo album.

These so-called “electromagnetic hazard” evaluations – which took place mid-month at Airbus’ Clément Ader facility in Colomiers, France – involved the second A350 XWB flight test aircraft, MSN3, to demonstrate necessary protection levels in case of lightning strikes while aloft.

The A350 XWB’s aerostructure is made primarily of composite materials (carbon fibre reinforced plastic), providing more electrical resistance than an aerostructure consisting mostly of metallics.

To ensure the A350 XWB aerostructure safely manages lightning strikes, Airbus developed a solution where metallic foils are embedded in the aircraft’s composite panels – increasing the aerostructure’s electrical conductivity and protecting harnesses with metallic conduits.

Metallic foils already have been used on the A380 rear fuselage section, however as the A350 XWB includes a higher percentage of composite materials, it is important to confirm that such foils provide adequate protection for systems and equipment.

The A350 XWB “electromagnetic hazard” testing on MSN3 lasted around three days, consisting of lightning strike simulations and follow-up measurements of induced voltage/current levels on selected harnesses.

This testing will be continued by similar but longer tests on the MSN4 aircraft in 2014, fulfilling a requirement for type certification of Airbus’ A350-900 version.

    Never knew it was that far in to the construction so thanks for that :)

    AIRBUS should put more effort on electromagnetic hazard/lightning testing in fuel tank areas and associated systems.
