Diff RR Engines On QF B744's?

Wed Aug 08, 2001 2:57 pm

Hi,

Are there different engines on the 'last few RR powered B747-400's' that were delivered to Qantas? There is a person in the Civil Forum who claims that the last few QF 744's have different engines than the earlier ones. If they are different they'd be -524H not -G would they not?

Regards,

Not sure,

I believe that Rolls Royce has modified the RB211 to give it some of the benefits from the Trent (not sure what these are)

It may be that that is what Qantas are fitting.

The Rb.211 upgrade XXXX10 is talking about is converting the engine to H/T status (I believe it is H/T). That is using components from the Trent in the core. CX and BA have signed up for this.

I don't know about QF's 744s but some BA 744s have upgraded engines that have slightly more thrust.

When was the -524H/T upgrade announced/offered? Because the guy says that the last few RR delivered 744's have the uprated engines. QF's last RR engined 744 was delivered quite a few years ago now.

The 524G/H engines are undergoing a conversion by replacing the High Pressure module with a Trent700's HP. It is more efficient and provides more thrust. The modified engines will be called either 524G-T or 524H-T.

I think most of the 744/RR airlines are joining this conversion programme.

QF also have a couple of 744s with GE engines, can't remember who they came from. Primarily used on the Pacific routes, I was on one SIN - CDG.

The Coachman, the last 3 QF 744's were received last year and are RR powered. The 6 744LR'S on order however will have GE engines, must be impressed with the way the 3 GE machines they bought off Asiana and Malaysia are performing.
BTW these 3 aircraft are not specifically allocated any particular route and fly the full QF 744 network.

Hi,

Thanks all for the replies. A former QF mechanic I know (left 6 mths ago) wasn't sure whether the last few RR engined 744's (that Jupiter2 mentioned) have different engines. I know that there are 3 'ugly ducklings' (mechanics term  Smile ) that have GE engines. They mostly fly Pac routes but aren't restricted to those (as Jupiter2 has correctly stated).

But I suppose my original question hasn't been answered quite the way I wanted it to be. My mech friend has left, so he can't give me up to date info. I'll rephrase it.

Did the last few RR engined 744's delivered to QF have the -524G-T engines fitted? And does this mean that US-Australia flights are not weight-restricted anymore?

Thanks again!

The Qantas RB211-524Gs are steadily being modified to RB211-524G/Ts. The new aircraft (VH-OJS-U) have these engines in all four positions, other aircraft have anywhere from one to all four modified.
There is a significant reduction in fuel burn, which improves planning on long sectors.
The only 'H' model RB211s are on VH-NLH, the leased BA aircraft.
