With the great advances that the 787, and the A350 will supposedly give to aircraft operational, and maintenance economics, could the technology have been in existence to create such an aircraft decades ago, perhaps in the 1980's.
I know that boeing use Cray supercomputers to design and improve their aircraft, and use a lot more technologically advanced, and more able tools to design their aircraft, though perhaps the CFCP fuselage, the raked wings, and the engines could have been conceived years ago.
As impressive and effective as the features are on the new green aircraft, they don't seem terribly complex. It doesn't seem to complex to create the CFCP fuselage, you just need a large autoclave. Though the GEnx is impressive, could'nt that have been designed around 15-20 years ago, as the technology isn't that different, its just the shape of the cowlings, the blades, and the materials used are different. If the wings do come out kind of curved, as it seems to in every diagram I see, then I can understand that that may not be straight forward to do.
So, could this have been done earlier, and if not in the 1980's, when is the earliest it could have been done, if not now?
