Yet the paper is published in 2025. And I'm fairly certain the early WS-10's BPR is >0.5. And skimming the actual paper it seems like a 3-10-2-2 (which is indeed a bit odd) while the WS-10 is 3-9-1-1.Err no. These numbers literally look like the earlier version of the WS-10.
Not really. Pretty sure the EJ200 is supercruise-able.BPR is superisingly high for a supposedly supercruise capable engine while TWR is very low
Edit: my goodness... This might be some sort of ultramodernised WS-9.
