OK, have they flown one yet? Because I'm going to remain highly skeptical until they do.
I was around the engine side for 40 years, and I've heard many, many proposals from the engine companies that sounded
wonderful on paper. The number than actually panned out in practice was small.
The 7J7 unducted fan worked fine on the bench. No so much when they stuck it on an aircraft and flew it.
BTW, it's not just the engine companies. Boeing and Airbus both routinely release pictures of some revolutionary new aircraft design (MacDac did the same before they bought Boeing). Yet somehow, commercial jet aircraft still look pretty much the same as a 707/DC-8...
