Thanks for an interesting and informative video. However one annoyance I'm increasingly finding on YT these days (including this video) is the mispronunciation of automated narrations. Turbofans become "ter-boffins", a 12:1 ratio, which should be spoken as "twelve to one" comes out as "twelve colon one". In the bigger scheme of things, this is not a major criticism of a good video, but it can be quite irritating. As regards open turbofans, I'm reminded of the Tu-114 airliner with large contra-rotating turboprops that created significant cabin noise. I would guess that mounting smaller diametre ones near the rear fuselage might also create a great deal of noise as the rear of the plane. The video does however make it clear that the CFM engineers especially are aware of the issue, which was problematic in earlier flight tests. I guess we shall just have to see what they come up with. I don't know for sure, but these engines appear to be larger diametre than existing turbofans. Under wing locations might require longer undercarriage legs and if so they would probably not be a retrofit option or a future adaption for an existing type without significant redesign and re-certification. So now where would open bypass turbofans end and turboprops begin? Thanks for an interesting video.

Turbo props are slower and noisier than turbo fans. Although powerful, their prop boom noise kills the business.

If this engine is called CFM them it is GE+SAFRAN, not sure I think that was reactivated in 2008 by SAFRAN 🇫🇷 if on comparison to LEAP this is 20% more economical ➕️ ready for hydrogen and hybride ➕️/or 20% powerfull !! And quite silent and as safe as turbofan ➕️ 900 km/h RISE is the good name and finally looks like fitting moderne planes Ps first having engines like 727 was the "caravelle" Wish success to GE-SAFRAN !!

I don't see much difference with the turboprop on the Airbus A400M and it's Hamilton-Sundstrand propellers with scimitar blades. The ducted fan prevents vortices forming at the end of prop blades, that is why it's quieter. If less energy is converted to noise, it's more efficient. The only advantage of open fans is weight.

You should also take into consideration gains in drag and weight when engines are ridden of the huge nacelles wrapping around them currently.

in 1959 Tupolev Tu-114 had 4 engine than operate almost like the Rise prop accept 4 of the engine had 2 4 bladed prop that rotated other way not like it has 15 blades put close together.
