RR Trents are THE BEST!

[ckyliu]

@julesgymnast And in fairness I feel I should counter the "big hand grenade" comment aimed at the Trent, by mentioning that the FAA ordered urgent inspections of CF6-45 and -50 last year because of 4 uncontained failure incidents. I'm not anti-GE but I do like to see a little bit of balance; RR may have not had the best of times recently with the Trent 900 issue but GE's history is far from clean, the CFM56-4B episode mentioned by @raykrislianggi is a prime example

@octaviorisso97 The official AAIB report agreed with BA, they say it was a freak accident involving the engines fuel-oil heat exchanger design and ice formation in the fuel tanks. I'm not aware of any serious GE90 incidents, but they were known to set themselves on fire occasionally when on the ground!

Having said all that, the Trent family also competes with GE's CF6 which doesn't have such a great record, quite a few incidents of containment failure with fan discs, that's downed a few planes.

@ckyliu oh I didn't know that, Thank you otherwise I still think that GE90 is better than RR Trent 800. Is true that 895 is better than the GE90-94B but the accident record is for GE90. A BA b777-200er with rr trent 895 had an accident when landing at LHR, from BA they said that it was a problem with the engine

[ckyliu]

@octaviorisso97 All BA 777-200ER with registrations G-YMMx are equipped with RR Trent 895s, the older aircraft beginning with G-VIIx have GE90-77Bs. I'd post links but YT won't let me, but I'm sure you know how to use Google. Anyway, out of 49 777s delivered, the later 19 are RR powered.

[octaviorisso97]

@douro20 yes, no doubt at all, but the next trent series had several problems such as the TRENT 800 and 900. the trent 800 in an accident in a British Airways flight, and the trent 900 with the QANTAS incident

[octaviorisso97]

@ckyliu mmm, I don't think so because there's no b777-200 from BA with RR engines

[octaviorisso97]

@raykrislianggi actually General Electric engines are the best

[ckyliu]

@julesgymnast Just for the record, Rolls-Royce was the first to 115k lbf with the Trent 8115, GE got a monopoly on the 772LR and 773ER because they offered to be a risk sharing partner in the project. GE90s have had reliability issues, BA actually switched from GE to RR T800 for their second tranche of 777s because of that very reason. Not heard much about the GEnx or T1000 on the 787, I know the latter was certified first but suffered an uncontained failure last year.

@Pumpkin8225 PROOF is in the vid watch?v=-XJYG8fxWhA

@Pumpkin8225 go search it up. GE uses carbon fiber composite blades with titanium edges on the blade tip. Not just that but around the shroud they also use composite materials.
