On the plus side the Michelins seem to be holding up well... maybe they ought to send 'em to Hockenheim.

*pssssst!*

Those are the leftover, barely used tyres from Indianapolis!
 
I think Jessica was praticing for the New Dukes of Hazard movie. :D Does anyone know the weight of the AC when this happened? If it was empty, what would happen full?

:D Haha... I knew it!! It was all a big conspiracy... they just needed the rubber to make A380 tyres.

Thank God for Boeing and "Body Gear Steering" on the Whale. Hehehe!!:D

Interesting pics...........

For those of you who aren't familiar with this one. . . someone was trying to turn AirBus' great big, brand-new, A380 aircraft a little too sharply (we don't know whether under it's own power, or while it was under tow).

AirBus elected NOT to make their main landing gear system (four separate gear with four wheels apiece) steerable. Why? You save a considerable amount of weight -- not to mention some serious extra cost -- by not doing so. There is a trade-off, however ...

When you have non-steerable gear that are configured like they are on this aircraft, you have scuffing/skidding going on whenever you turn the aircraft. This isn't an unusual design for a wheeled vehicle, though. For instance, a dual-axle semi-trailer does the same thing when it's being maneuvered sharply within a warehouse parking lot. What makes the A380 so special, is the incredible amount of weight on each huge tire, in conjunction with the widely-spaced gear.

In concert, these two aspects considerably magnify the inherent problem -- to the point where the asphalt (not just the rubber tire) is taking it in the shorts ... not to mention the stress and overload that's happening to the entire structure between the tire and the gear attaching points in the wing structure. Note the apparent bending of the gear in one of the shots! No, Mildred, that is NOT a good thing to be happening to your aircraft's main landing gear. Unless they're making everything out of rubber, those stress loads have GOT to be off the scale!

As new-aircraft design problems go, this will likely prove to be a very expensive one for AirBus to deal with. It's either that, or the aircraft will only be able to operate in and out of airports that have the extra fifty-acres it will need to get safely turned-around. It'll be interesting to see how they solve this one.

don't we need to be an employee of CO or COEX to view these links?

Yeah... dayum is right! That ain't going to fly. The first time some ham-fisted cap'n gets a hold of the tiller she'll be riding on the rims. On the plus side the Michelins seem to be holding up well... maybe they ought to send 'em to Hockenheim.

Another plus for Michelin is that they will sell millions of tires to Singapore, ETIHAD, Emerates, Korean, Virgin, Quantas, Thai, FedEX, UPS etc. after tire changes every 2 landings. :rolleyes:

From what I here in the cargo world, FedEx may indeed cancel the 380 orders due to the floors cannot withstand the weight in relation to the size of the airplane for cargo and airbus' anticipation. The engineers are scrambling to come up with a solution, to add, they do not have enough engineers to work on the 350 and are in absolute panic mode due to the late arrival of the 350's with the timing of the southeast asia/india avaition explosion. Looks like europe's socialist company arrogance has finally caught up with it.
 
I think my Dash 8 could disappear into the ruts made by that thing. Better fix it Frenchie... That ain't gonna work.
