You could count turbine blades as propellers...kinda.
The real propeller is actually the compressor, which is what you see at the front of an engine. There really is no difference between the two; physically as both are fans using airfoils to compress air. Although a straight propeller isn't often thought of as a compressor or fan that's more a language thing as that more or less what it is.
Though in actuality all modern airliner engines have a propeller generating a high majority (80+%)of their thrust. 'Bypass' air is air that hits an initial large diameter fan and is compressed, but not heated and utilized by the turbine hence 'bypass'. It's contained by a shroud however making it a ducted fan, but that's a matter of pure semantics; a 'ducted fan' and a 'shrouded propeller' are one in the same. The fan is driven by the turbine rather then a reciprocating engine, but said fan is still generating most of the thrust.
In fact when a modern airliner uses 'reverse thrust' it's reversing only bypass air since you can't really flip the direction of exhaust from a turbine as easily, but this is still more then sufficient to produce a net braking or reversing effect despite the fact the core air is still thrusting the opposite direction the entire time.
The three jet engine design, eventually differed on the proportion of thrust generated by the fan and the gas expansion. :)
CMIIW, pure jet thrust engine is more efficient when they are going to be flying near or over supersonic speed, so it's more commonly used by fighter jets or bombs/missiles that has jet engine.
I mean isn't a crash kinda just a sudden unplanned landing?
Aircraft Carriers Tried Flying
Kaga! we're flying! See! Our base looks so small!All you can eat!? AND all you can drink!?I can drink all the beer I want!? Hyahaa!!You calm down. Why did you even board this plane?Calm down Akagi. There is no possibility a plane without propellers can fly.
