But that's not a lot to go on to understand how the new CFD tools helped. | |

As you can probably see from some of my other questions, I'm interested in the evolution of airfoil technology in the 1975-2010 period, and there was considerable progress from 1975 - early 1990s, where wings could be thicker and cruise at the same speed without incurring wave drag penalties. But post-777 , I wonder how much more gains there were to squeeze out of the airfoil. | |
