PARIS 2007: Rolls-Royce flies Boeing 787’s Trent 1000 engine on 747 testbed
Rolls-Royce has flown its Trent 1000 turbofan – the lead powerplant for Boeing’s 787 twinjet – for the first time, aboard the UK manufacturer’s 747 testbed. The first phase of the engine’s flight test programme is being conducted from Waco, Texas.
“We gave the engine a hard time for its first flight, but it did everything we asked. It was very stable and predictable,” says Rolls-Royce chief test pilot Phill O’Dell.

Quoting KELPkid (Reply 1): I'm assuming that there was less development work involved with it (due to the developmental nature of the engine) than there is with the GENx.
I'm not convinced that this is a safe assumption to make.......
There is some significant new technology involved.....
It does build on the standard Trent 3-shaft architecture, though.

Not necessarily so. If I'm not mistaken, the GEnx is a derivative of the GE90.

Quoting DeltaDC9 (Reply 17): The windows are usually not that particular config when it is a retrofitted 741.
Incorrect. Many airlines decided to dump the lounge (with limited seating) on the upper deck after the early-70's oil crisis, in favor of more seating. Thus, the section of the fuselage with the 3 upper deck windows were removed and replaced with a fuselage section containing 10 windows.
Example (same aircraft; first in 1972, last in 1977):

OK, take a look at that 200, then look at the 100's you posted and tell me if you see something different.
Quoting Zkpilot (Reply 21): Isn't the 748I supposed to have engines along these lines...
Yes, but with a sloghtly smaller fan diameter, but it will still be much bigger.

As I understand, all but the earliest 100s were built with windows in the frames, but plugs in the holes. Some operators intially opted for only three windows in the upper deck but later removed the plugs and installed windows. The fuse section was not changed.
Spell check is a false dog
25 N231YE: The first 747-100s (and even the first 7 -200s) were built with 3 windows on each side. The 10 window option became available in the summer of 1971,
26 DeltaDC9: That was my point, and why I said look at the hump before getting pounced on. The retrofitted 100 and the 200 are not identical. You can tell them ap
27 Adipasqu: Where did you get this 7 ft number from? According to Boeing's own detailed specs, the upper hump on the -100 and -200 are identical: http://www.boei
28 DeltaDC9: The windows on the main deck are the ruler. The location of the little things can be determined by that. The stretch happend on the 300, the 200 and
29 Adipasqu: I agree that the planes are not identical, but their humps are.
30 N231YE: My bad, the upper deck was extended 6 feet internally, and I got it from the book; Boeing 747-100/200/300/SP by Dennis Jenkins, part of the Airliner
31 Imiakhtar: Either i missed it or RR just added it but there now is a short video of the test flight http://www.rolls-royce.com/media/showPR.jsp?PR_ID=40493
