A6 Intruder----Question?

Hi guys,
-
Thanks for the response.
-
Yeah, I'm former Navy myself---SEABEES, Builder Rate.
-
"Awhile back" for me was about 1991 to a commercial airport, just south
of Scranton, PA , them doing a military air show, also with the Blue
Angels F-18's. I think the facility was called Aviation Park, just off
Rt.81.
-
It was a two seater A6 Intruder with a refuelling arm out the front of
it and one Navy pilot in a flight suit was tending to it, he looked
kinda' bored. I should have asked him my question then, but I didn't.
I was looking in the tail end of the engine. These "turkey feathers"
were right there at the rear end of the exhaust, a circular ID laying
and overlapping and interconnecting other "turkey feathers," they were
laying on top of the ID of the external metal of the outer combustion
chamber. Sorry about the lousy description, I'm not familiar with the
jargon of such stuff.
-
I frequent rec.crafts.metalworking and I 1st posted these questions
there. One guy wrote me privately to try your site here as to a more
detailed explanation. And the best explanation so far, if indeed it is
true, from a Brit off the metalworking site. I thought former Navy
aviators would have given a more detailed, aerodynamic engineering
explanation.
-
But thanks anyway,

"Don't know how they're made but the tail feathers are used to form the
variable geometry exhaust nozzle. They close down or open up to control
the jet exhaust and hence thrust. I suspect that they are titanium."

Hi,

I was to an air show awhile back. I was inspecting a Navy A6 Intruder. I
caught the exhaust end of the tail pipe and noticed a circumference of
mesh "feathers" on the inner ID, that honestly looked like dragonfly
wings, gossamer in texture. I wonder what the function of this is, what
the material is, and how is it produced? A stamping process is a guess.
Material---titanium?

No, I'm not into the inner workings of such.

Thanks.

Some guy thought he knew what he was talking about when he spouted:
"Don't know how they're made but the tail feathers are used to form the
variable geometry exhaust nozzle. They close down or open up to control

LMAO! Nope- not even close.

Prowlers and Intruders (all flavors of the A-6 family) just got a little
bend in the exhaust- nothing more.

Thanks for the chuckle! :-)

Maybe he is talking about the "turkey feathers" on a F110-GE-400 or
the TF-30's on the Tomcat? Either way his message don't make sense!
