ANA 787 Trent - 1 Year Anniversary; 100% Reliable

Wed Nov 07, 2012 9:56 pm

The one year anniversary has come with ANA utilizing the 787 Dreamliner powered by the Rolls Royce Trent 1000 engine.

With over 17,000 flights at ANA, the Trent 1000 has delivered dispatch reliability of more than 99.9 per cent, along with delivering 100 per cent inflight reliability.

ANA currently has 15 787s in service with 51 more on order.

I've just got back a couple of hours ago from the Raes lecture by RR CEO Mark King.

During the post-talk drinks, he mentioned a 99.9% dispatch reliability for the T1000 and said that it had been the smoothest ever entry into service for an engine.

He also mentioned another interesting snippet which will be bad news for RR Trent lovers: the trent family is going to be replaced by a new, more composite engine.

Exciting times at RR.

Stay tuned!

That is inevitable. Developments go on and on. This is the next step in their evolution. i wonder which aircraft they are thinking about to introduce such an engine. The B777-X is most probably getting GE engines, maybe again exclusively?

Exiting times. But the Trent family is not done yet with still new versions under development.  .

Hmmm, how quickly we forget the flights lost to gearbox issues. I know this was not directly a RR issue, and not technically a "schedule interrupt", but certainly not what I would describe as "smooth".

I think the jist of what he said was that the new engine will replace the entire Trent line up and as such it is not aircraft specific per se.

There was an American guy from Bloomberg who asked about the development timeline of new RR engines so hopefully something should pop up there in the next few days.

I would have paid more attention had it not been for the exceedingly pretty Chinese embassy attache sat next to me!

OK, I understand. Thanks for your answer.

That is however a more then acceptable excuse for not paying more attention to the technical details.  .

Who knows. Or maybe the A380-900? I read that RR was trying to offer a newer engine then the T-XWB for the proposed B777-X. But that could also possibly find a place under the wings of an A380-900, or later an A380-1000? If they are ever built of course.

The engine in question is the RB3025, a concept engine for the 777X which would utilise a composite fan and entirely composite fan case. In comparison the Trent XWB currently only uses composite on the rear section of the fancase.

As this is only a concept engine it may never see the light of the day, it all depends on who Boeing selects to power the 777X. However RR now have the ability to incorporate this technology for whichever new large engine they conceive, wether its for a future Boeing or Airbus widebody.

I might add that the XWB 97k or Trent 1000 TEN will not use a composite fan or fancase.

100% reliability..? Wasn't the B787 fleet grounded @ one point due to an issue with The power plants...?

Other than that great news and congratulating both Boeing and ANA...

I'm trying to see if I can get on the 787 flight for my trip to Japan in March, but every time I look at Flightaware I see that the 772 was subbed in.

Inflight reliability. That means the ANA crews haven't shut down an engine inflight. Doesn't mean or imply there was a Trent that needed an engine change upon arrival.

The gear box and non-dispatch items go under the .01% of the 99.9% dispatch stat.

Nice but hardly objective. It's word for word the RR press release.

Meanwhile, if ANA are so happy with their Trents, I wonder why they haven't yet confirmed an engine choice for their recent order...

I wouldn't think so.
One would think Boeing would want to offer something for those with Trents on the 787. More than likely a new Rolls would still have more in common than a GEnx and a 777-X GE engine(i guess a new GE90?)

IMO 777 will be a two engine game like the 787....once again Pratt sits on the sideline.

More like all those Trents on the A350 XWB, if you can't get the same engine on the 777X as you have on your A350-900's might as well buy the A350-1000.

So for the technically challenged I can understand using new materials for the fan etc is a big deal but why is changing the fan case to composites a big deal. I can see it could get hot but it isn't rotating at x0000 rpm etc!

Well spotted. You're right, he didn't. That was my mistake posted in haste.

Quoting trex8 (Reply 19):

The reason put forward was weight.

On the Trent XWB, he mentioned it is currently achieving a 16% fuel burn reduction over the Trent 700. That delta will increase after some fine tuning though.

The fan case right now are typically aluminum with a kevlar wrapping for fan containment.
Making a large circular case is not a simple machine operation.

If you can use fiber placement technology similar to the 787 fuselage. Generally you can also get about 20% weight saving converting from aluminum over to graphite epoxy.

Because they're in negotiations...it's gonna be RR...the only time when a carrier ever swaps engines mid-stream is when the engine they have is severely underperforming or they're absorbing a huge fleet with another engine type. Neither applies in this case.

It saves several hundred pounds per engine (more than a thousand pounds per aircraft). That type of weight savings is nearly unheard of for a straight-out material swap.

It's not particularly hot...fan ducts rarely get over 200F, even on a hot day takeoff, and the case is shielded somewhat by the acoustic liner anyway.

I understand the T700 to be around TSFC 0.58 lb/hr/lbf, now 16% down on that is 0.50 which would be sensational. Airbus has said 2% better then the 787 spec which I believe is 0.528, that would be 0.518 .

So what is it, around 0.52 or 0.50 ?

I don't think either of those conditions applied when BA swapped from GE to RR for their second tranche of 772 orders - there may have been other specific reasons but it does illustrate that swaps between suppliers are not unheard of.

He didn't mention specifics unfortunately.

Rolls-Royce has a target of a 1% fuel burn saving per annum for new engines, and the Trent XWB was meeting that target.

One of the main advantages the Trent has over other engines is its weight saving. Typically over 3.5 tons on a B757. Making it even m,ore lightweight is going to be a huge advance.

Carbon fibre blades though have been too brittle for the 12LB Turkey test so far.
