Not clear to me from the article - what's the different between an 'open rotor' engine and a turboprop (https://en.wikipedia.org/wiki/Turboprop https://en.wikipedia.org/wiki/Turboprop)? At face value, both seem to be jet engines with propellers used on single-aisle planes?

There is still a jet stream coming out of the engine propelling the aircraft. Unlike a turboprop where only the propellor generates thrust.

  > Unlike a turboprop where only the propellor generates thrust Each of turbojets, turboprops and turbofans generate thrust with exhaust.

    Turboprops have no meaningful thrust component from the exhaust.

      Almost. Wikipedia says 10%, which is kinda meaningful but really not much. Even some piston engines (like in WW2 fighters) get 2% or so from exhaust.
