What power ranges do the various Trent engines cover? How are they distinguishable externally?

I understand that the Trent 556 used in the 340-600 has 56000 pounds of thrust. This seems to be the same as the power each 747-400 engine produces. Does this mean that the Trent 500 series is a direct replacement for the RB211?

BA on their last batch of 777-200ERs ordered the Trent 895 which is a 95,000lb version of the Trent 800 series. Delta has on their 777-200ERs the Trent 892 which is a 92,000lb version of the Trent 800 series. United on their 777-200ERs has the P&W 4084 which is a 84,000lb version of the P&W 4000 series.

The Trents on 747-400 can be easily distinguished from PW or GE powered variants by the single piece cowl/nacel, as opposed to the two-piece used on PW and GE engines.

There are no Trents on 747-400s. They use the RB211 engines, which if I'm not wrong, was based on the design of the Trent or something.

Hi,

Singapore 777

There are Trents on 747-400s. Few example, Quantas, BA, Cathay and few more but just to prove my point !!

Cheers Mate

Those are not Trents! Those are RB211 engines, which were the base for the design of the Trent series.

Rolls-Royce 747-400 211s have had some cores replaced for efficiency etc, with a core of a Trent, and the rest as per RB211. This is what BA has done: not a whole new engine.

I believe that the RB.211-524H's used on the 747-400 has many core components common with the Trent engine.

Does anyone know how much the Trent 556 weighs? If the weight is less than that of the RB.211-524H they could be candidates for a 747-400 re-engining program.  Smile

I am a bit surprised that the A340-600 uses engines with the same power as the 744. Isn't the -600 a lighter aircraft than the 744?

Isn't there going to be a new RR Trent 600 series on the new 747X models? I know on the A380 it will be equipped with RR Trent 900 series.
