It's strange, A330's CF6 doesn't remind me of CF6 on 747 or 767. CF6 on 747-400 and 767 sounds basically identical to each other. Yes, I know each has their own variants.
It's the number of fan blades. The CF6-80C series used on the 747 and 767 have 38 fan blades, resulting in a buzz-to-whine pitch ratio of 1.1875 (and some octaves), where the CF6-80E series used on the A330 has 34 fan blades, resulting in a buzz-to-whine pitch ratio of 1.0625 (and some octaves).
QF aren't fans of Rolls after the QF32 incident and they're very glad they ordered their 789s with GEs after RR's 787 problems too. I don't think we'll see RR engines with flying kangaroos for a long time.
@@paulstewart2ndchannel They first received an a330, VH-EBA in december 2002, roughly 8 years before QF32 happened. But that plane has GE CF6s, not trent 700s. That’s why i’m surprised these have GE engines, they didn’t hate RR until 2010.
The CF6 has more power and a muuuuch faster spoolup than the Trent 700s, and the former in particular is important for Qantas given the amount of “hot and high” takeoffs that are performed in our climate. Hell, RR made the even more powerful Trent 972 engine for the A380 pretty much specifically for Qantas and Emirates because we need that extra grunt. At the time of ordering, they already had CF6s on the majority of their 747 and 767 fleets so even though there’s a number of differences between the C and E series engines it makes a lot of sense to keep rolling with them to help reduce the number of different spares required and extra training.
Great video Paul . Has everything , wing fluffage , intake vortex , the whole lot . Thanks for sharing .

@@FL2070Love this!
Nice video. Really felt like I was there.. very clear detail. Love the take off and the turbine screaming noise
It sounds like a giant refrigerator.
I really thought Qantas would choose the trent 700s, since they are an avid RR customer

@@paulstewart2ndchannel well they did choose a350s (RR) over 777x (GE)

Nice CF6-80E1 sound
Oh, I miss Auckland!
What is the aircraft registration
I'm afraid I can't remember
@@paulstewart2ndchannel No problem. I like your videos.
Epic!
