View Full Version : A380 UC test/failure depending on....

.....depending on the story or email you have recieved, these are the images of the Turning radius tests, aircraft towed in ever decreasing circles till this point...... or..... airbus stuff up with lack of rotating/steerable UC trunions.




on a less serious note, im surprised that with such tarmac damage, the tyres didnt unseat themselves from the rims.

looks like there tyres are holding up better than their F1 tyres. personally, i love my Faulken Alzenis :)

Is that tarmac damage or tyre debris?

Looks like a serious problem with the body gear wheels.
Any idea what was behind this gem??

How else are you going to get this thing into a tight parking spot if you don't do a 24-wheel broggie?

my understanding is it was a delibrate test.Torque link was disconnected on nose, and wheels were positioned at 90 degrees and then pulled by a tug to check were failure point is for the gears/wheels.

i am pretty certain its a test. you can see scrubbing of the sidewall of the rear tyre where it has been tested in the other direction.

This was adequately dealt with by the recent article in Flight International. It was a test - taking the gear to beyond it's design limits, right up to the point of destruction. It was deliberate and, according to the manufacturers, gave VERY satisfactory results.

It is the landing gear equivalent of bending wing spars until they break - intentional, destructive testing. Boeing will have done the same on their aeroplanes int he past and will do so on the 787 in future.

The original "disater for airbus" e-mail clearly came from America due to it's mis-spelling of "tyres" as "tires". I wonder how close to Seattle it's origin will turn out to be?
