Then we have the 'test number' uninstalled at high temperatures (not used in F-35) without other equipment NOT taking power from engine. One would assume that 'uninstalled' means no equipment taking power from the engine? 'TEG' answered that somewhere here.


One would assume that, special circumstances aside, published values by the engine maker would be on a bench. That they're almost universally "bench" (test stand) values. So when GE claims a 10% improvement without saying over what it's a useless statement.

Ten percent of whatever the thrust is? Shirley that is significant. Ten percent of anything is not bad at all. I want it now.

Sure. But you can get a 7.5% bump just by changing your source from Lockheed Martin to Pratt & Whitney. No money or time required. :wink:

If they're using P&W numbers, then it's a 10% increase from 43K (~47.3K.)

:devil: Just run the engine hotter (like Ruskie Engyns) and your uncle is bob. :doh: No waiting for engine failure though. :roll:

Have to hand it to GE, great video.

One of the best facets of capitalism is competition, and the great engine war between GE and Pratt and Whitney is a fine example. Both companies have produced killer engines. Oh how the Chinese and Russians would love to get their hands on one of these. The F-35 is only going to get more capable, thanks to these advanced motors...

Except... that the bit @ 1:11, “It’s the only engine...” is patently false.
Take an F-16, stir in A-7, dollop of F-117, gob of F-22, dash of F/A-18, sprinkle with AV-8B, stir well + bake. Whaddya get? F-35.
