What will revolution require?

Tue Feb 11, 2020 6:47 pm

Tubes, wings and two engines are likely the standard for decades to come in the world of civilian airliners. But what's the tipping point for revolution? What level of fuel savings or seat-mile cost efficiency is needed to convince manufacturers and airlines that it's time for something new, and that something new makes sense? Or can such gains only be incremental to the point of negating a revolutionary design?

Probably a new airplane manufacturer that's not in on it already. That's pretty much the only way I see planes departing from tubes and wing to blended wing bodies. 'Neo' versions of the a350 and 787 will probably be the last true tube and wing airliners along with nsa.

The last revolution, in the 1950s and 60s, was built on new engine technology (the gas turbine engine in place of the piston engine). A true revolution will require a similar step change in engine technology. A safe bet would have to be on electric engines, but the timing of that will depend on energy storage technology to a large extent. Failing that, nuclear fusion?

This is my opinion as well - a new engine technology similar to the radical change from props to jets. Most likely will still be "tube with wings, two engines hung below." That seems to have proved to be the most efficient design barring BWB, but BWB comes with quite a few challenges when it comes to use in commercial aviation. Those challenges have been covered extensively in previous topics on the possibility of going that route for future aircraft design

I think that there would need to be a full requirements change for there to be revolution. A tube works pretty well. Why invest so much time and effort when the return is marginal. I don't think that there will be truly revolutionary engine design that isn't driven by a core need either.
