Another issue with this exhaust arrangement is how are they going to do a S curve in the exhaust, the flow path is now much shorter. Americans are likely going to include that in their designs judging by all the patents out of PW and GE.
Newer turbofans will be a lot shorter than current ones, leaving enough space. WS19 already shows that you can achieve an overall pressure ratio of 35 with only 8 compressor stages compared to the 12 stages of WS10. The compactness of advanced engines improves much faster than the weight of the engine, probably because of the extreme heat dissipation requirements.

I don’t much like the new design since it looks like they took a bite out of the plane’s butt. But as Yankee hinted at earlier this year the redesigns are results of flight testing, and we must respect science.
like if they are gonna change the exhausts they should have at least move it further back so it does not look like the entire back section is missing lol. rn it looks so dogshit im coping so hard rn.

I don’t think they moved the exhausts forward. The reason that the original design looked like the engine is further back is because of the lower flaps on the engines jutted out further. The upper petal on the engine is at the same place. Now that 2D TVC nozzles are used, which not only has uniform upper and lower petals the same length but they are both shorter and smaller than the original design so the visual is a lot more jarring.

TLDR — it’s not the engine placement but the geometry of the nozzles.

yea ik i meant that they literally should have moved the new nozzles further back so it looks more aesthetically pleasing XD
