First metal cut for A380

justin · 01-25-2002, 12:00 PM

There was a small ceremony on 23/01/02 when the first metal was cut for the A380. Components will start to be shipped to the assembly plant next year.

Actually, an Airbus Executive cut himself on some metal from a beer can during the ceremony. Like the Dragon models, Airbus will only use a bare minimum of metal on their planes and go with plastic and composites for the rest.

Well it makes sense, after all composites can offer superior physical properties and less weight

CHING! I....... was......... here

justin, you got a point there. I built identical wings in A&P school. One out of 2117T Alclad aluminum, and another out of polystyrene airfoil with a fiberglass, and epoxy resin covering. when it came time for the torture test, the metal airfoil was easily dented, bent, and made useless in no time. The composite wing easily withstood being stomped on, and driven over by a half ton pickup truck. The only bad thing about a composite structure is that it goes through delamination (separation of the fiberglass layers) which weakens the structure to the point of failure. in the next 10-20 years alot more parts of aircraft are going to be composite because the potential is endless. Most nights i clean and service an RON 737-83N for ATA, and just getting into the cargo bin you can see the parts which were once metal are now composite materials.

I don't think there is any doubt that composites are the way forward. Another problem they have in addition to de-laminating is notching and their resistance to foreign object damage. The Harrier 2 uses a lot of composite material, when it was developed they had huge problems during the tests for FOD as somponents were shattering and tearing. Obviously a ground attack fighter has to be capable of withstanding a certain amount of this kind of damage, they got it sorted out in the end though. They are also a pig to repair, compared to metal which is really easy to work composites are a pain in the ****** to repair.

it's true, it's true

Say Dave, what's a "RON 737-83N"? I know it's an -800 in ATA colors but what does "RON" stand for?

DavidMich · 01-28-2002, 05:35 PM

RON--- Remain Over Night, term for aircraft that stay at an airport for cleaning or maintenance overnight

justin, if you remember, Rolls Royce originally developed the RB-211 engine for the L-1011 with composite Hyfill blades, but they too would crack and fail on the water ingestion test, and a flight where the aircraft flew through a dust cloud. The ice test wasnt pretty either.

Hi, I don't personally remember the original RB2-11 but know about it as my father was an engineer for RR on the original RB2-11 program

That bankrupted RR and was a key factor in the relative failure of the L1011
