RB211
Some of my notes quote the full name as "RB211-524H-T" while others say "RB211-524GH-T". Which is correct? And what do the letters stand for? I know T is for Trent fuel control system, but what about the other(s)?
Thanks

G series modified. Hybrid Trent? Vaguely remember that from somewhere.

RR like to call them RB211-524G/H-T, but it's covering 2 types:
there's the RB211-524G with the lower thrust rating of 58000 lbs and the
RB211-524H-T with 60600 lbs thrust and the Trent Hot Section.
CX operates the H-T model, but de-rated to -G thrust.

T is for the trent hot section. Something that was added later from the original design.
The G and H are for different thrust ratings. You can have a RB211-524G-T at 58,000 lbs thrust with the Trent core. You can also have a RB211-524H-T at 60600 lbs thrust with the trent core.
The difference between the two is basically an electrical shorting plug on the FAFC (the brain). Change the plug and you have a higher or lower thrust as needed. However, if the engine has been released from the workshop and test cell as a G rated engine then it will only ever be a G. But you can release it from the cell as an H and allow it to be either.
You could make a G an H but it has not been certified as such and then there could be trouble.
Really its as easy as A B C.
Hope that clears it up, and you can quote me.
P.S T has nothing to do with the fuel control system. Just the Hot section (combustion chamber back, and an extra bleed valve) from a Rolls Royce Trent engine.
H has nothing to do with wide chord blade technology or Hybrid trent.
