BA have retired their fleet of 747's and 767's. So have Qantas. Is anyone else still flying RB211's on a widebody? If not, it's been a bit over 50 years from conception to out of service, which even with the various derivatives is quite a long time. It's an engine that almost killed RR, but by the s...Jump to post
The T500 was not of poor quality. It was just a limited market on a 4 engine plane vs the 777 and sales were low. The engine itself performed to spec. This from lowbank who works at RR: - I am also interested in the real use of a a340 as I worked on lots of T500 parts. Shame a late design change sc...Jump to post
GE effectively paid for exclusivity on the later 777 versions. That was financial not market. And it meant RR was off the platform. However way you look at it the T800 just wasn't as good a return for RR as the T700 was. RR bet on the A340 and the T500 and both the aircraft and the engine were lemo...Jump to post
You are aware that on the first generation of 777 (prior to GE exclusivity), RR (with the T800) gained the largest share of the market? 777-200 -300 - 200ER: RR 40% PW 30% GE 30% "Not great in the market"? What does that say about the (original) GE90 or the PW4000? Yes, I am aware of that...Jump to post
What's interesting considering they're a family of engines is the huge variance in quality and market success.

All I can say to you guys is, as I understand it. We are given a fan diameter and a power output required, SFC etc. Normally the power request goes up but the fan size stays the same. Go figure what happens. Going back to the XWB, as I remember it. The initial request was around 80k and 90k thrust ...Jump to post

Never mind the windows, what is interesting about this is they talk about it as a narrow body replacement. All blended wing ideas that I've seen so far have been very big planes.

Interesting article from Leeham news.
Jump to postBoeing likely faces an extended timeline to clear its inventory of 400 737 MAXes. LNA estimates it will be well into 2022 before these new-production airplanes are delivered to customers.
GE Aviation is laying off 70 temporary workers from its site in Bromont, Quebec, citing Boeing’s decision to halt 737 Max production as one factor leading to the cuts.

As I understand it, in this configuration the main wing and the engines can be far back, so you don't get a wing spar in the cabin, and the noise is back there. That would probably be even more the case if they just had a cannard and main wing. I heard from an instructor (so take this with a grain ...Jump to post

The current limits i think are to do with the moving parts and the engine cycle used. The ultimate jet engine would have no moving parts, and would not burn fuel in the engine. Experiments with high voltage electric charge of air has started as a propulsive force to sustain flight. While in the ver...Jump to post
Both RR and GE wanted exclusivity on the A330neo because they did not want to fight over the frame when they had both spent billions on the far over budget T1000/GEnx programs (often overlooked here because of focus on Boeing) that they would probably never get back from 787 sales alone. They are/w...Jump to post
400 frames deliveries would be financial a roaring success. In regards to RR, it is not a complete new engine, but an engine based on components out of the building kit. 800 engines plus spares would be dream come true for RR. Quite correct - and one reason both GE and RR insisted on exclusivity - ...Jump to post
Can the 777-9 really carry an OEW penalty of ~25T over the A350-1000 (16%), carry ~8-10% more people and deliver the same CASM? Dubious. Very very dubious. I'm equally skeptical, but it does have engine tech that is half a decade ahead of the XWB, and 10 abreast seating. I do see the 777X as the A3...Jump to post
Like you, I wasn't there, and whilst I would like to believe everybody here on a.net knows the difference, my understanding is that a supercharger uses a mechanical drive from the engine (or sometimes from a secondary engine), whereas a turbocharger utilises "free" energy from exhaust gas...Jump to post
Are we also renaming 'turboshaft' to jetshaft or shaftjet?
