GEnx first test
Looks like the FETT went smoothly, up to near max thrust as well.

OAT was about 10C below ISA, so it's not difficult to get plenty of thrust on initial test. But it's always good publicity! :ok:
|
already more than 575 engines ordered for three new commercial aircraft Boeing 787 Airbus A 350 and ? |
...B747-800

It's amazing how easily 'thrilled' these chaps are....:cool:

All I get cobble together is that you can run the HP system faster with a greater fuel flow, as T4 is effectively cooler. Hp runs quicker, LP runs quicker, more air chucked out of the fan at a quicker speed. More thrust??? Or is that all boll*ocks? Anyone care to shed a bit of light on it for me?? |
Cold air is more dense than hot air, therefore more mass for a given vomlume of air moved. Same reason that engines lose power with altitude, generally.
