New GE Turbine Engine for Airbus
Attached are four photos of a GE Test Engine up in Mojave, CA.
They use a 747 aircraft as the test bed and remove one of their normal engines and put the test one on instead.

This engine is slated for the A380 Airbus Behemoth Double Decker that is being built.
You will get some idea of the size difference between it and the normal 747 engines.

The normal 747 engine is somewhere in the 60K lbs/thrust where this one is about 125K lbs/thrust!


Don't try a cross wind landing when the wind is from the left. 
If you dropped the left wing, you'd scratch one engine
