Rolls Royce Engines Not Preferred On 747s?

Fri May 04, 2001 7:39 am

I have noticed not many airlines opt for RR engines for their 747 fleet, why is that? in the 70s and 80s it was just Saudia, British Airways, Qantas, Air New Zealand, Cathay Pacific and some examples of Malaysian Airlines 747s that had Rolls Royce engines, in the 90s and at present its again just Qantas, Air New Zealand, Cathay Pacific, British Airways, South African and Cargolux any others? why are General Electric and Pratt & Whitney engines more popular with 747 operators? Smile/happy/getting dizzy

I think this is because the RB211-524D4 engines that were installed on these 747's were quite thirsty powerplants, as well as being significantly heavier than the P&W JT9D's or GE CF6 engine options, due to the shorter and fatter cowling design.
The RB211 engines were good performers in 'hot and high' environments, which is a reason why airlines such as Saudia and Cathay Pacific used them, Saudia in particular (Saudia used the RB211-524 powerplant on it's L-1011 TriStar aircraft).
The Malaysian Airlines RR powered 747 was actually purchased from British Airways, which is why that particular 747 had RR powerplants.
I love it when a plan comes together

And to kill two birds with one stone, here are a pair of RR's over Saudi.

It's a BA flight enroute to London from Singapore. Nice view of the desert!!

Great shot! but the fact that youve posted this picture in its enlarged version is very annoying, the small one would've done, we could've enlarged it ourselves, I hope Johan takes note Angry

Here's another nice photo of a pair of RB211s taking this QF 743 to ..........some place....!

I think one reason could be that the RR has a higher fuel consumption than the P & W and GE. Of course there are other considerations such as commonality, price and maintenance costs.

VS also has some RR powered 747s.

I think it looks nice in large form. By the way, how did you do that? That is a nice picture!

What's interesting was that Rolls-Royce recouped a lot of the investment in the RB.211 because they did get it qualified on the 747. That allowed R-R to build the smaller RB.211-535 series, which became the most popular engine on the Boeing 757.

Because of the longer nacelle design, this is why R-R engines are quieter than P&W engines because of the better mixing of hot and cold gases, which muffles noise more effectively.

I think the Rolls Royce engines are a bit more pricy then the other two and that I think is a reason for that choice.

It's interesting that most RR operators have strong ties with Great Britain. Commonwealth, Hong Kong, Saudi Arabia (Back from the early oil years).
But definitely, the RR on the 744 is the most graceful.

The RB-211-524G and H have lower thrust ratings than the GE and PW competitors do they not?

Cathay bought the Tristar with RR engines becuase of Britains persuasion. That's when Cathay's relationship with RR started.

For the same reason that I drive a VW not an RR. Not everybody can afford the best.

Cathay Pacific is a big customer of Rolls Royce given CX is owned by Swire Group which is British and RR is also British. CX's fleet is all powered by Rolls Royce except for Airbus A340-300 as there is only one powerplant available, which is the CFM56 engines. CFM is a consortia between General Electric and Rolls Royce so therefore there is a link to RR there through Scema.

The RR engines on Boeing 747-400 and Airbus A330-300 aircrafts look the best.

CFM International is a consortium between GE and the French SNECMA (not scema) and not with RR.
By the way RR is in business with PW in the IAE V2500 programme.

The RB211 class engine have the lowest fuel consumption in it's class, it is quiet (stage 3) and it is easy to maintainence

Steman is right. CFM is GE and SNECMA. Rolls Royce is part of IAE like he said.
Rolls Royce has a reputation for being the best, but more expensive.
