Ok, that very clear, thanks. Btw, is it the rotating fan that is producing the so characteristic sound of the CF6-50? Are you thinking about the initial start sequence with the whine? It's all present from CF6-6s all the way up to -80E1s (+LM2500) from the videos I heard. No, it's the high-pitched ...Jump to post

The noise "growl" you hear at about the 50 sec mark is the harmonics of the flame front when the fuel is introduced. You can see the condensation from the air starter up until the turbine becomes self sufficient to accelerate rotational speed up to idle and the starter is dropped out. The...Jump to post
The GE engine is longer than PW, so the turbine safety zone is further back in the wing. Just a guess but that’s a factor in other designs.
Why we're getting a lower fuel capacity with GE? Slightly off topic, the A320 with IAE engines have a slightly less Wing Tank capacity than the CFM counterparts due to the incorportaion of a Dry Bay inside the the Wing cell around the pylon area for additional safety. This can be a reason, however ...Jump to post
The mentioned Boeing PDF file contains a lot of errors, so far I was able to check on short notice : - Page 23 : 747-200 engines is completely incorrect - Page 24 : 747-300combi (Air india) powered by CF6-80C2B1 engines has also been produced. IMHO an inaccurate copy/paste PR product, not checked a...Jump to post

I assume we're going to get a lower range with this. According to StartupBoeing's 747 classic PDF , Boeing gives a lower fuel capacity (few hundred gallons) for the GE engines in 747-200/300 compared to PW and RR engines. Why we're getting a lower fuel capacity with GE? I don't think engine weight a...Jump to post

Anyone know if this sub type was certified for fifth pod engine ferry and if it was ever done ? Syrian 747SP, YK-AHA, 1999-09-01, MUC, with 5th pod installed : https://www.747sp.com/wp-content/gallery/21174-284/21174_yk-aha_old5engines.jpg See : https://www.747sp.com/747sp-production-list/21174-284...Jump to post
FYI: RR did make an engine for the 2nd generation 777s.
It's called Trent 8104 (104000lbs thrust?) and made 110000lbs in testing. Making it close to the GE90-110/115s.
But GE came and take all the money away and airlines only have GE on offer.
