Is the aircraft fitted with an EPU system?

Might want to poke about their site for JSF info..

Ciao,

I have been in contact with some folks from Lockheed about this very subject and the answer I get is "we are still hammering out the details on system configuration"

There is NO EPU, there is an emergency hydraulic system but it is nothing like the EPU we all know and love so much.

Good, then no more zene responses. Woo Hoo!!!!.....I am keeping my fingers crossed.

You can uncross your fingers brutha, it's a fact from a test engineer on the JSF program here in F/W. You won't believe the fuel system.

Please don't tell me that. Not something I want to hear. I would much rather do a zine response. Especially if the fuel system is complicated

That complicated? Bang Head

Relative to an F-16 it is, all three varients fuel systems are different.
You won't believe the boost pump capacity even without an FFP.
I can't give figures here but it's pretty impressive.

Wing changes?!?!?!? Is that a concern for fuel shop?

Dude you're going to Buff's right? You're supposed to cast away any and all caring for the fighter world when you go to heavies Wink

I can't never cast away from the Viper.........I'll be back. Maybe in 15 years or so, but I'll be back.

I'm back to 16's! Well for three years now and wudda you [Link pending approval]'m going to be on 35's in about a year! (formerly CM)

The F-35 uses high voltage electric motors with fuel powered hydraulics, where lesser aircraft would use actual hydraulic fluid and cables for backups. And don't forget that they've scrimped on the lightning and fire protection to save weight.

This aircraft is going to be a (literal) blast to fly. Wink

BTW: How come the non-American 5th gens don't get their own folders? Where do we post T-50 vs J-20 comparisons?

Because they're more like 4 and 9/10ths. TSFG
