Weight Loss for Superjumbos: The A380 and the Aviation Engineering Dilemma

A look at the technical details and the story leading up to the cracks that have been appearing on the Airbus A380’s.

“The ribs are made of innovative composite materials containing carbon fibers. “The corresponding brackets are the real problem,” McKenzie explains. They connect the cross strut with the outer skin of the wing and are made of an especially lightweight aluminum alloy, which has the unfortunate drawback that it is subject to cracking in this particular location. By using these high-tech materials, the Airbus engineers were able to reduce the weight of the aircraft by a few hundred kilograms, which is considerable. They did not see the use of the materials as a risk. “We’ve used this alloy in many other aircraft in the past,” says A380 designer Williams.”
