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.

To what extent is the Trent 1000 new, and to what extent is it based on previous Trent/RB.211 designs?

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.

Don't these engines look BIG on a 747?  Smile

I'd figure there's got to be alot of new toys inside the cowling, seeing as how it is a bleedless engine.

Not as big as a GE90-115  Wink But a little bigger than stock  Smile

That thing is big. Dwarfs the regular 744 engines. I bet the pilot would love to 4 of those hanging on the wings.

I believe it is a 742 with RB211-524C's and not a 744.

Sorry, it's a 742. However, the hump is the same for 741 and 742, I believe.

Looks like RR has a leg up on GE in this respect: GE's flying engine testbed has P&W JT9D's in the non-test engine positions  Wink

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

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):

Isn't the 748I supposed to have engines along these lines... although GE rather than RR... You may yet see a 747 with 4 big engines  Smile

OK, take a look at that 200, then look at the 100's you posted and tell me if you see something different.

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
