That is one mother of an engine!

the
new European Aviation Safety Agency. Even though it will operate
initially
at a maximum take-off thrust of 70,000lb, the Trent 900 is cleared at
an
80,000lb rating, allowing margin for future growth. It reached thrusts
in
excess of 90,000lb during early test bed running.

With a fan diameter of 116 inches, the Trent 900 is physically the
largest
engine ever built by Rolls-Royce. It is also the world's cleanest
large
turbofan engine, measured by emissions per pound of thrust.
