Rolls-Royce has delivered the first of its engines designed for Airbus's A380 "super-jumbo", a double-decked aircraft due to enter service in Spring 2006.
The engines have been specially adapted for use on an A340-300 jet in Toulouse in order for them to be flight tested.
The engine will provide 70,000 lbs of thrust at take-off and its makers claim it is the world's cleanest large turbofan engine measured by emissions per pound of thrust.
The manufacturer has also been working to reduce noise emissions from the engine in order to meet regulations for departure at London airports.
The Trent 900 will be used on 48% of Airbus A380s so far ordered. The other planes will use US Pratt & Whitney engines.

Is GE offering any engines for the A380? Also, it has seemed to me like PW has not made it onto very many jets. The most recent ones are the 777 and the A330. Is PW begin to decline in its ability to keep up with Rolls Royce and General Electric as an engine-maker for many aircraft. Lately, it seems Rolls Royce and General Electric have been able to produce engines for almost every new type of jetliner lately. Besides the A330, the more recent A340, 773ER, 744ER, and 7E7 and A380 have all had either or both Rolls Royce engines and GE engines. Why can't PW keep up?

Oops...Seems I provided some false information. Just discovered PW and GE have formed an alliance for producing engines on the A380. Guess PW is a lot more on the ball than I thought.

HELLO!!! This was covered! Listen this is being used on the A340-300 jets...that means that it has been "covered". Although I still think it's amazing because of the size...
So they say it supposed to have 155 "more" seating then our current jumbo. That's pretty good but for the size of the plane you would think it would accommodate more than that...hmm odd.

The reason why the Trent 970 is such a big engine is the fact with the 116" (294.64 cm) front fan diameter, the front fan can turn at a slower rate for that 70,000 lb. thrust, which reduces the engine noise quite a bit.

if you saw the pics of GE's 747 that they used for testing the GE90 it might give an idea of what the A340 testbed will look like with one of those huge engines on!
After Monday and Tuesday even the calendar says WTF...

All this excitement over the A380 powerplants one can't help thinking about the basic mathematics involved.
A380 4 x 70 000lb engines = 280K for 550ton
744 4 x 60 000lb engines = 240k for 400 ton
Thats 16.6 % more power for a potential 37.5% more weight. You don't have to be a rocket scientist to work out that a FULLY laden A380 might need a LONG RUNWAY and the curvature of the earth. In other words the A380 will share more than just fly by wire and handling characteristics with its smaller brother the A340-300
This is not to inflame Airbus fans but looking at the figures (116 in fan) but the sooner AI fit the superb GE 90-115B (128" 90-94 123"?)larger versions of A380 of current model may fall short of promised performance.
Now an A380 with 4 773ER 115,000lb GEs... now that would look and perform IMPRESSIVELY!!!!
This is just my view on the above spec's and is posted for iminent discussion on this wonderful board!

Look at the size of that thing - a man-eater!
Looks like we are building a Saturn V rocket here to go to the moon, not an airplane for daily flights... lol

This has been debated before and wing efficiency helps in giving more lift for a given area but ultimately its THRUST that counts.
The A380 will undoubtedly be much more efficient than 744 although 280k thrust and 550 tons is not going to be spectacular thats for sure

26 DC-10 Levo: Nice shots, but I'm still not a big fan of the A380. Aicraft due to enter service in Spring 2005? I thought it was later than that. DC-10
28 Bmacleod: Jet engines have definitely entered a new era. Makes the 777 engine look more like the 737-200. AWESOME!!!!!
