So it’s like, How much more bypass can you get?

And the answer is none. None more bypass.

Damn loudest thing I ever heard. Stupid loud. I hope this idea stays dead.

These are fascinating engines. But basically the same as a Turboprop.

Geared fans in some of the newer airliners are showing greater efficiency boosts than a UDF would have. As well as the fact that this would’ve probably only worked on an MD-90 anyway.

Would you say it went all the way up to 11?

Yeah, the big fan engines of today work just as well without the tradeoffs...it wasn’t a technology meant for this world, but it did provide useful data.

If not, it means they found a way to make ten louder.

Yes. It also pegged the Samrt gauge:

I know a couple (old now) that worked on the team that developed that engine. The wife was on the engineering team and it was supposed to save lots in fuel, but she said they were not used by the airliners because they were not good looking and passengers would not want to look at them.

Probably for the same reasons that passengers think turboprops are “old propeller planes.”

Yes, yes I would.

What’s the benefits? I thought the spinny bits were supposed to be on the inside for maximum go?
