Scanning some old slides today and came across these. I took these at an Elmendorf open house in 1985. The Hasegawa 1/72 scale kit has this part in it, but I've never seen one built with it. From what I hear, this thing made A LOT of vibration.
That "french Tickler" was a POS!!

I remember after we installed it on our Hog's virtually every one of our A/C had cracks in the nose area. My A/c had a big ol crack in the Nose wheel well. I was so glad we took it off! to be honest, I don't think we kept it on the jets long enough to see if it made an impact on gun gas ingestion.

That sounds pretty bad! That's some serious vibration! I'm surprised they wouldn't have tested it out more before installing them on A/C in service - or does that make too much sense?
Thanks for sharing your story.
Did you ever see the film or photos when the gun

was first installed and fired? Sam Nelson was about ready to bail out!
Who thought that thing up!?!?!?

Looks like something from "Warhammer"...
I bet the guy that came up with that thing got paid some Beeeeg bucks, even thought it didn't work!
We stole the eagle from the Air Force, the anchor from the Navy, and the rope from the Army.
On the seventh day while God rested, we overran his perimeter, stole the globe, and we've been running the whole show ever since.

Referred to as the "Batelle Device", it was designed by the Battelle organization of Columbus Ohio. Prior testing to divert gun gas included just shaving the muzzles alone and a nose fairing that completely enclosed the gun muzzles.

An example of SGGI, relatively small. I've got a picture somewhere of one with the fireball about 25 feet in diameter. Engines don't behave when they suck that in.
Another try at diverting gun gas - the nosey - on s/n 73-1665.

The pilot doesn't do well, either

At one point, the fireball fully enveloped the cockpit. All Sam could see was flames. The nose probe was replaced with a wood plug before the flight. The fire burned away the softer wood in between the grains. And yes, there was a sudden thrust loss. So, besides the gun gas diverter, they made changes so that the gun gas/exhaust wouldn't be as apt to enter the engine inlets.
WOW! I've *never* seen the droopy nose before!

How long did that last? Not a single A-10 reference I've ever seen has had that one in it.
I think some of them only lasted a couple of flights.

The airplane would come in, show the burn marks, and someone would say, "naw, that didn't work", and it was discarded. No reason to use it again, if it didn't work once. It was a nasty problem.
Is that the Kinetic A-10

just a guess by the shape of the nose
Hey Keith how goes it? Need to get in touch with you soon.
