How about from the horses mouth...since no one believes me. Per Dozer: "you're seeing the spray bars, nothing fancy, just where we dump in extra fuel for the AB". Like I said, part of the augmenter section.

-Check

No offense, but what kind of quote is this? Did Dozer (might want to mention who this is, although I do know who you're referring to) read this thread, look at the pictures I posted, and then privately email/message you the info you've quoted above? Perhaps you could have him comment in this thread himself?

Always glad to help. If you look really hard you can actually see the spraybars.

I'm certainly not going to go to all that trouble for you, having him come here to explain it, but I will explain it further. I PM'd Dozer on fencecheck and simply asked about it, which he found time to answer. I already knew it had to do with the augmenter of the engine as I asked a maintainer (the folks that actually make it so the plane can leave the ground) on the ramp one day back in 2005. For those who don't know Lt Col. Michael "Dozer" Shower, was the heritage flight F-22 pilot and now is taking command of a squadron in AK that is standing up Raptor's. Currently all the AK Raptor's are being delivered to Langley for logistical reasons....Check

Yeah but those don't look anything like what we're talking about. Also notice they're quite a ways up the pipe too. What we're talking about is sitting almost out at the beginning of the nozzle. Most of us have seen up the back ends of enough engines to know what spray bars, turbine stages, etc look like.

Well... it's hard to know the details of your private conversation with Dozer.

Was he looking at the pictures I posted with the yellow arrows pointing to the devices in question?

Anyway... it's not straight from the horse's mouth if the horse, so to speak, isn't here posting the answers to the questions raised in this thread himself.

I have no problem if those devices really are just flame holders. I'll be a bit surprised, but I won't be disappointed. However, you haven't done the best job at defending your position. I really don't have a position except perhaps that the devices in question don't look like any set of flame holders I've seen to date.

Oh... and you don't need to start going on and on about how important maintainers are in the grand scheme of military aviation. I'm not putting down your profession, but don't think you know everything about the jets you work on/around on a daily basis.

Let's get real here. You were saying that the devices I pointed to on the pictures were "part of the augmenter system".

That's not engineer speak and shows a lack of familiarity with basic afterburning turbojet/turbofan engine design.

You were refering to the flame holder. That's what makes the afterburning on an afterburning turbojet/turbofan.

That's the only clearly visable component of the afterburner that the mass flow passes through. You can't blame me for being skeptical when you don't even know what those devices in the F-22's tailpipe MIGHT be. If you had said, with authority, that those things in the F-22's tailpipe were the flame holders, I'd have been more inclined to take your word for it.

Raptor One. You asked, here's the answer. Standing behind the engine looking from the foward. This is what you see in order. From front to back.

1. The last stage of LPT blades.
2. Turbine frame struts. (That is what you highlighted)
3. Aug fuel spray bars. (If your looking hard enough)
4. And the item of debate, the flameholder. The Dark outline is the Outer Gutter. The white bars are Mid Gutters. The dark circle they meet it the Inner Gutter.
5. Working your way out is your aug liner. (With all the cooling holes in it)

Like I said earlier, all flame holders do not look the same. There are different designs of flameholders. Don't look nothing alike, but provide the same theory of operation. Which is aiding the air off the mixing duct and fuel out the spraybars provide the best performance airflow wise and at the same time controlling the form of pattern in how it burns.

That's the first seemingly authoritative posting to contradict the claim that these devices are radar blockers. Care to list your source and put the debate to rest? Please don't take offense to my asking you for the source of your information either.
