Well, RR engines are crap anyway. I've flown them on two types. They;re
needlessly complicated, labor intensive to maintain and they leak oil

Bertie, by 'cabin', do you mean the portion of the turbine that houses
the vanes?


No, by "Cabin" I mean the portion of the airplane that the people sit in.

The pressurisation for almost all jets comes form the turbine section.
Several engines, most notoriously, RB211s, leak engine oil into the turbine
section where; it's heated, pyrolised , and then injected in a fine mist
into the cabin where it causes nerve damage to the occupants.
All jet engines do this to some degree or other. RR engines, particularly
the RB211 and particularly the early engines, inject lots and lots of this
into the cabin.
Nice.

It's a huge problem worldwide. It's barely discussed in the US....
The ramifications for the industry if this is ever looked square in the eye
are mindblowing.
Boeing have gone with a seperate blower for the 787 because of this
problem.
