CFM International has outlined some of the technologies that will allow its Leap-X new generation narrowbody engine achieve 16% lower fuel burn.

The article also mentions CFM is working on an open rotor design with a 4.27m diameter fan envelope. Where would you place a 4.27m diameter fan on an aircraft?

Not on a 737 class narrow body, that fan is half a metre greater in diameter than a B737 fuselage.
It would likely be neat retrofit on the AN-22 or TU-95 replacing the 5.7 metre contra rotating turboshaft engines!

Airbus and Boeing have been studying alternative configurations for over a decade.

Keesje, can you post your 150 seat turboprop again, it seems you just found an engine for your design!

So we are finally coming back to the UDF idea. I was wondering how long it would take.
