One F-135 takes up less room and generates more thrust than two rival engines combined and completely outclasses the other two

Intake cross section says it all ... that motor is scary big for a fighter!

I believe you have OPR and Bypass ratio switched.

The turbine inlet temparature of staggering 3600° F alone shows how advance the Pratt&Whitney engine is.

Yes , you are right !

Let's see Euro fanboys come in to spin this one.

Wow. I wasn't aware of how "small" European engines are when compared to most of ours. They are much closer to the GE F404/414 than any of our larger designs.

Let's see one with the F414.

Well, the F135 does push the "overweight" F-35 AA-1 with a 9 ton payload (fuel and weapons) faster than the F110 can push a "hotrod" F-16 with only 4 tons of payload (fuel and tank)

Do some serious reading about the F135 online. Some of the declass stuff is amazing. The control system is going to be unreal, not to mention the power.

Cool

The size of the European engines has to do with development time and costs and the plane they are supposed to propel. The downsize is that when doing engine overhauls the user might have to need spares for mismatched engine removal timings.

Seconding this. Plus, why not throw in some of the other well known engines that power other fighters from around the world.

Shingen, there's no need for fanboys to spin anything...duplex' initial assertion is pretty much wrong, all along.

First, EJ200 takes ~24%! of F135's volume, while producing almost half the thrust (and more than half in wartime setting, according to released data).
Second, higher TW ratio partially comes from higher OPR and higher bypass, making F135 "slower" engine, however.
Dunno for sure, but I'd say F119 has worse TW than F135, which only speaks of its purpose, not technology.

So no, F135 doesn't take less space then even a poker of EJ200s and it's front cross section is larger than even a trilling of EJ200s.

This is basic geometry and has nothing to do with spinning and is just one example, of what I've said in my prior posting.

Someones upset...and spinning Wink

The F135 is at least 15 years younger than the M88/EJ200, you better hope it offers some superior specs given its newness which allows it to benefit from the technological advancements made in the meantime. The operating temperature (if true) is indeed impressive, but the gains in TWR and OPR aren't that dramatic. So yes you have a comparably more powerful engine, big deal.

Btw don't complain about the evil "Euro fanboys" afterwards if you make such lame, provocative comments in the first place. It's almost an invitation to a flame war and just shows how immature and fanboyish you are yourself. Rolling Eyes
