Jet engine and wing efficiency have increased enormously over the last 50 years.
With diminishing results.
Turbofans and supercritical airfoils are done to the point of engine manufacturers looking to propfans and alternative materials (carbon fibre) to eke out further efficiencies.
Although carbon fibre has significant down sides.
