The first 2 lines, one for the fan and one for the core, enable the units to be built up vertically, representing a break in tradition for Rolls.
Each line has 6 positions, with engines “indexing”, or moving position down the line from station to station every 24hr.
The floor of the line moves on rails, allowing the engine to shift to the next station without having to be craned into place, as was the case under the original assembly process.
The next 2 lines will provide a site for the horizontal integration of the fan and core modules and an area for final preparations before dispatch; this includes borescope inspection, cleaning and packaging.
The pulsed lines are “agnostic” to engine type and currently are being used to produce both Trent 1000s and XWBs. However, the investment is geared toward the coming growth in deliveries of the A350, firm orders for which translate into an orderbook for more than 1500 engines.
“The line will be used for building Trent XWB-84s and -97s, and mostly -84s over the next 2 years” said Simon Burr, Rolls-Royce COO for civil large engines.
“Rolls expects to deliver 70 XWB-84s in 2015 and ultimately we reach a rate of 1 a day over the next 2,5 years; so that is 1 every working day by 2017, or around 250 per year” he added.
“It is important to note that the investment in the industrial system and the development of pulsed lines reduces the time needed to build each engine, as well as the lead time. There has been a lot of effort put into the XWB to make production easier” he said.

Fantastic- 70 engines by this year's end- thats 35 aircraft -where will Airbus keep all those engines! To think that they are the most technical and the most complicated part of any aircraft. No FAL holdups here then.ReplyDelete
It has been noticeable in past few months that the generally non biased media (not American media) has noticed the general slow production of the A350. Even this blog, which is very pro Airbus noticed a 2 month period of no deliveries. Looking at all the blogs here, it seems that far from suppliers holding up proceedings its the other way about. With such a good product, the A350 is making inroads in Airlines minds.Thats all for the good but this 'laissez faire' atitude is becoming noticedReplyDelete
