Turbine rotor break-up? The safety containment seems good.
What do you make of it?

where's quoting a turbine rotor break-up?

It's got four of 'em! Losing one ain't a worry!

Not good for RR = not good for me
I'm not involved with the civil stuff, but this is bound to have some company wide effects, if indeed it was engine failure (which it looks like)

What like this?

"where's quoting a turbine rotor break-up"
No-one. Though it was mentioned in passing on R4. I don't know enough about the design of these to guess what came off what. But something took out a chunk of the nacelle housing toward the rear. I can't tell properly from the pics, but something small might have penetrated the wing.
Impressively safe aircraft by the look of it. Hope RR get to the root cause quickly. And given the engine looks in quite good shape, that seems likely.

My experience with Quantas ain't great, last time I flew a Quantas Jumbo to Sydney the bleedin projectors kept overheating, so we had nowt to watch for 24hrs. Also, all the cabin crew, in my part of the plane, were mincing queens, no female eye candy to chat to. I think I was sat by the bogs aswell, Yorkshire Airlines have outside loos, which is much better.

Well that's a compressor failure in your vid, not a turbine stage.
I've had a turbine blade come loose and take out a fair portion of the latter stages; engine carried on fine albeit with a HI VIB caption.
Can't see the big deal in an engine failure on an A380 really.

Do you lot work for RR then in Bristol? I hear there's a Java dev job going

Really?
Looks like bits of engine when straight through the wing, which wouldn't be too great if there was a fuel tank at that point.
Also looks like there may have also lost full control of No 1 engine and some hydraulic failure. (or at least the conjecture on PPRUNE was suggesting that earlier)Posted 1 year ago # -
Just grabbed this from a newsfeed, Associated Press pic. There's some nice video shot from a window looking straight along the port wing showing a jagged hole just back from the leading edge, and a smaller one further back.Posted 1 year ago # -
A news story for sure, but not worthy of the air time I saw it getting at tea time. Most highly stressed part of airplane fails shocker, but everything else went fine. No kittens were hurt.
The news story comes later when it has been investigated. The engineering might interest me, the facts of the incident without any flesh doesn't.

I work there as an apprentice, in my final few months. Checked the vacancies and it showed the java dev job as being in derby??

LOL! Failure sure, engine blowing up sending shrapnel everywhere is a tad serious no ? Although not confirmed and could be something else, the above pic shows what *looks like* wing damage (top of wing under the "r" in Australia)

That is indeed the outward protruding edges of the hole that was filmed from inside. Something pretty chunky went AWOL and exited through the wing.

In itself, the engine failure isn't the problem.
It's the fact that the failure wasn't contained within the engine casing; the wing appears to have been punctured, not too far away from the fuel tanks, and there's a strong suggestion that control of No 1 engine was lost!
However, a good deal of conjecture, just glad of a successful outcome.Posted 1 year ago # -
"Spirit of Australia" is this the Fosters corporate jet?

I wonder how far the thing flew up in the air.. and where it landed.

Was thinking the same allthepies. Bits of metal raining down with speed from a great height is not going to end well if in a built up area.
I had the huge excitement of standing under an A380 that took off from Manchester airport a few weeks ago. It was spooky as this huge machine seemed to glide very low and slow and disappear into low cloud.

A load of debris landed on a small island, enough for them to believe that there had been an airplane crash!

I wonder if it was explosives? seems all the cowling in the photograph has been blown away - shrapnel sort of - I thought all the turbine blades were contained in an titanium envelope that is tested under destructive conditions? ( watched the RR program on telly a couple of months back RR at Barnoldswick) - the cowling is a sheath that fits around the engine but does not contain moving parts ?

Another closer view from allvoices.com
You can see the wing damage a bit clearer here.Posted 1 year ago # -
A pic from the intake side would be good - anyone found one?

Turbine is surrounded by sheet metal air transfer structures and the nacelles / cowels. Turbine blades are (relatively) small.
I think you're thinking of the fan blade (massive on a wide chord engine) which are encased by the fan case (titanium / kevlar structure).
Fan Blade Off is the destructive test during an engine certification

There was definitely wing damage! watch the vid here
http://www.guardian.co.uk/world/2010/nov/04/qantas-airbus-a380-engine-failureSounds like it took 30 minutes or so to shut down the left engine too

My bet is on the same wear issue that led to the 787 engine test failure.

Oops! I retract that - I hadn't seen a pic!! That looks fairly catastrophic. Turbine blades should normally be contained, but not always successfully.
I'm guessing looking at that wing you could have damage to fuel, pneumatics or Hydraulics and possibly flight/engine control data feeds. The bleed air and Hydraulics will have plenty of redundancy, however a fuel leak isn't pleasant if you can't isolate it. Wouldn't like to have had FBW cabling damaged either.

For anyone who is interested there is some pretty sobering reading in the Investigation report, extracts of which have been posted here:
Catastrophic damage to the slat actuators and transmission drive shafts as well as fuel pipes.
Some serious failings highlighted of other systems too including unable to transfer fuel between the two wings leading to heavy imbalance. The plane stopped only 100m short of the end of the runway with the brakes reaching about 900degC with fuel pouring out of a ruptured fuel tank. Almost, very almost a complete disaster.

It's true you know!

So what're the long term implications of this for Airbus and RR?
Posted 1 year ago # -
Nearly several hundred crispy people there.
Good save by all concerned.
QANTAS is getting dangerous since it outsourced its maintenance.

Speaking to a retired rolls stress engineer the other day.
It was definately a rotor failure as he saw one of the islanders on the news carrying a section of it like a trophy.
Apparently it's the biggest failure you can have and it is impossible to contain although extremly rare thankfully.
This was as it was told to me I have no idea if it's correct but I trust the guy who told me if I am wrong so be itPosted 1 year ago # -

Rare, unless you have an oil leak which leads to a fire internally in the engine which then leads to the failure of said component!
Don't go buying RR shares too soon.
Posted 1 year ago # -
Wasn't there an oil leak though? Thought that was the root cause of this one.
