Impressive.

Wow. That's about 1/5 sea level air pressure. I can't imagine a system able to maintain that while handling the turbine's output gasses.

Truly something to look forward to in aviation.
Interesting. Although it's kind of disappointing to see OEMs continuing to dump millions and billions into fossil fuel R&D and not electric or other green R&D.
It's a step in the right direction. Unlike the symbol next to your name.
A 20% improvement in fuel efficiency and corresponding reduction in greenhouse gasses is significantly green.
Agreed, plus this engine if so certified could likely run on non-fossil synthetic kerosene aka SAF.
