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.

From the third paragraph in the linked article:
"The engine is also suitable for applications in hybrid-electric or electric transport and can generate more than one megawatt of power."

Hopefully they were smart enough to ensure that some of the parts (and gains) could be reused for a electric prop. With all of GEs knowledge of wind turbines you think some of that would cross over to this and other similar designs.
