The answer lies in your bathroom...CERAMICS! Wink

That, and heat resistant metals, like titanium are prevalent in jet engines.

Next time you look down the posterior of a Viper, take a look at the interior portion of the nozzle. The heat shielding is laid out in sheets over each individual section of the nozzle.

When I die, I want my body strapped into the afterburner section of a fighter, while sitting on the trim pad, and have the run guy light "Zone 5". There won't be much of me left to worry about burial costs, and whatnot. Wink

Funny, that's the same place I'd look for the answer to the problem of being way too drunk Razz

TC, thanks for the answer Smile

While I haven't been here long - it's not because I haven't been reading the links. I've enjoyred this discussion and I have to jump in and say that the Raptor is amazing.

I'm a Viper driver and I've had the opportunity to fight one (well, a couple really.) Without going where I can't go, I have to say that the Raptor beat up on me, my formation, the Eagles, and the other red air without me ever seeing him until he rolled in on my 6 and gunned the tar out of me. Wasn't much I could do about it! I have fought many other jets in the world - Eagles, Hornets, Hogs (for what that's worth), MiGs, Mirages (2000 & F1), and several other types & nationalities I'm forgetting about I'm sure - I have lost some, but won most fights. The Raptor changed the way I thought about fighting - I have never felt so defenseless before, I'm just glad I am on their side.

The earlier posts about it not being about the Raptor's maneuverability are right on - between how high, fast, and how amazing his technology was we (the many red air) were dead about as fast as the controller could pass the words. I am used to a rhythm in air-air engagements and they just destroyed the tempo - their tune was over before we had really even started.

The bottom line: I was a skeptic and thought it should be done away and replaced with new Bl 60 Vipers - now . . . well, to repeat myself, I'm just glad I'm on their side. Now can I have one too? If not, then I'd be happy to jump on the second line in a new Bl60 or F-35.

Oh yeah, it is a hell of a lot more manueverable than a Viper.

VprWzl, thanks for some firsthand information Very Happy

! It's great to get the straight scoop in a case such as this Cool

What unit do you fly with and what is your call sign?

Hi VprWZl,

How do you think the F-22s thrust-vectoring affected the outcome of the engagements?

Amazing story! Welcome to the forum BTW! Always nice to have another expereinced oppinion around here!

Ahhh..Yes, yes..

It is always nice to get another pilot over here.

The TV nozzles didn't affect the outcome of those engagements. They were determined by speed, RCS, & technology.

In a later fight one of the Raptors demo'ed a break turn for us - since we'd probably never see one in a fight. It can turn up it's own tailpipe - if I ever got to a merge I don't think it would last long.

I know with the F-16 engines the outer 'shell' is also cooled down (somewhat) by the small amount of bypass air flowing around the core. Hence you are able to jump the exhaust after shutdown without burning yourself beyond recognition. Razz

Thanks for the input VprWzl Smile

I'll probably be quoting you when someone says that the F-22 sucks!

lol, we've got video's on one of our servers with the 22 doing a backflip while maintaining forward momentum...lemme see if I can dig it out and host it somewhere.

Hmmm...sounds like a particular Russian maneuver that the Raptor was supposed to be "defeated" by. Laughing

I've watched it swing it's @$$ end around, quite like a Porsche throwing up the handbrake and cutting the wheel to one side...

...only tighter!

Beers and MiGs were made to be pounded!

What are the G's the pilot gets on that maneuver? I imagine it approaches nine... and Calhoun I hope you can dig that clip up, I love watching the Raptor do crazy sh*t like that!

Actually Sniper, I'm no expert, but I don't think the pilot would take very many G's at all from a maneuver like that. Since the plane is level and moving forward during the maneuver the only G force on the pilot is down. Since the pilot will be near the center of the centrifical(sp?) motion of the maneuver he would experience a lot of excess force pushing him to the outside of the maneuvers arc, since it is so tight and what not...

I could be completely wrong but it sounds to me like the G force would be a consistant 1 g perpendicular to the ground. (someone correct me on all this if im wrong, cause i am TERRIBLE at physics!)
