Finally found something..............though it is the GEnx not the trent..............
From the Seattle Post-Intelegencer
"787 engine performs well in first test flight
Initial step toward certifying design
With the first flight of The Boeing Co.'s 787 only about six months away, the new General Electric engine that will power the Dreamliner made its first flight Thursday -- on the wing of a 747.
"The engine performed extremely well, and we look forward to gaining additional valuable information on the engine's capabilities from flight testing," Tom Brisken, general manager of the GEnx program, said in a statement. "Today's flight puts us another step closer to certification later this year on the GEnx-1B engine for the Boeing 787 Dreamliner."
The engine is being tested on what's known as a "flying test bed," in this case a modified 747.
Flying out of Victorville, Calif., the 747 climbed to more than 43,000 feet during the initial three-hour engine test.
Over the next three months, General Electric plans about three flights per week as part of the test program leading to engine certification.
Rolls-Royce is also developing an engine for the 787."
Looks like GE
not only have more orders than Rolls-Royce but are a little ahead in testing as well.
edit to say "you beat me to it!"
Quoting Glideslope (Reply 4):
Quoting Lumberton (Reply 3):Been trying to find this out, too. Any news?
Yes. It's been flown. There was a post a few weeks ago with the 1000 on the 747 during climb out.
I thought that was the GEnx. A couple of weeks ago (maybe more) FI had pictures of the GE 747 testbed flying out of Victorville, CA with a GEnx engine attached.
