CR2,
Funnily enough the Trent (dont know about the PW) is a smaller profile than the RB211, CF6 and JT9.
The main reason is that on the 3 Original "Big Fans" they were shipped with the fan installed ( could be removed but major hassle!)
The Trent is very easy to remove the engine minus Fan in fact the Fan can remain on the wing.
The core engine is a very much smaller profile as the fan is the major size restraint.
L1011F will carry an RB211(inside that is)
