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?

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.

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!
