Does anybody think that a Boeing 744 can be fitted with RR Trent 556 engines (same ones on the Airbus 346)? Will that ever happen in reality or not? What will happen to the flight performance of a Boeing 744 with RR Trent 556 engines compared with those of current GE, PW, and RR engines? Thanks.

I would imagine the 744's performance would drop because I believe it's powered by engines making around 60,000 pounds of thrust, the 346s only make 56,000.

The R-R replacement of the current RB211-524 Engine used on the 744 is the Trent 600. This would replace the 524 where R-R is used on the 744 and the 767. As far as I know there are no firm orders for Trent 600 powered A/C (yet).

The Trent 500 is certified at 60,000 lb of thrust and derated to 56,000 lb for the A346, and 53,000 lb for the A345. Thrust-wise, it would meet the need of a B744. But the Trent 500 has a much larger fan. To fit the Trent 500 on a B744 would need a lot of modifications. Rolls is proposing another derivative, the Trent 600, for the B744XQLR. Boeing has yet agree to offer a brand new engine on the new B744 derivative due to additional development costs. Cathay is most definitely interested in a Trent 600 version of the B744XQLR. We just have to wait and see.

The RB211-524G/H series engine have a modification to fit Trent cores in the existing engine, the result being the RB211-524G/HT. This has led to improved fuel consumption (near the original specs that were never reached) and lower operating temperatures.
