Boeing747-400,
I'll try to make this as clear as possible for you......firstly, I agree with Boeing on the 747X Stretch, it would be stupid of them to develop a brand new aircraft, especially with such a proven design......if I had an airline, I'd go with the 747X, I wouldn't want to rely on Airbus to come good on all of their promises......the A380 is incorporating an awful amount of brand new technology, it's all not going to go right....
However, with all due respect, you are basing your opinion on artists impressions of future aircraft...... Boeing never wind tested any of the designs they thought up, there was no need........anybody can sit down with a crayon, and come up with a nice picture, Airbus do it too......FYI, the 747X and Stretch are based on the basic 747 structure, the basic shell is the same, with some extension and reinforcement.....some of the systems will be the same, some won't.....they pick the best the market has to offer, however there won't be much revolutionary stuff, simply because there is no need.....Airbus on the other hand, have taken it upon themselves to come up with a new aircraft, and they have to take the problems that come with it......one of Airbus' biggest problems in the beginning was that when they designed the virtual aircraft, its systems, structure etc., it was grossly overweight, and because of this, they needed to incorporate some revolutionary technology.........the hydraulic system will now be 5000psi, instaed of the traditional 3000psi...this allowed Airbus to make all the pipes and ducting smaller, and thus save a great deal of weight........the 747X will not have this, because there is simply no need......Airbus also pumped much cash into the development of GLARE, a new lightweigt glass-fibre composite, from which the upper fuselage panels will be made....again, this will save a great deal of weight........the 747X will not have this, because again, there is no need......
As for the aircraft as a whole, it is not completely designed...most of the engineers working on the A340-600 will now move across to the A380, and the design will be completed......just because an artist drew a picture of the A380 10-15 years ago, does not mean it was designed, it was simply what it was....an artists impression.......
My point is, the A380 will incorporate technology that the 747X will not have........it does not mean it is superior to the 747X, it means that technologically, the A380 has more.......Airbus are creating a whole new design, and therefore are prepared to spend more, Boeing are updating an existing aircraft, and will try to keep their costs to a minimum........it doesn't mean one is better than the other, both manufacturers are just approaching the market from different angles......
Simple as that....
Rgds...
