The Plasma Thread…….caution!

Ok I said I’d start a new thread on the subject of novel (in this case see Plasma) stealth technologies.

Here it is.

I would like to try and keep this on a sane level, with no rubbish. I would hope the mods would be able to keep an eye on things and sift for c**p, if they dont mind, since I think this cold be eye opening for everybody.

I’ll start by saying that we should try and keep this in a hypothetical regime, so instead of stating the mig-21 would do this etc etc I’ll just keep things slightly ambiguous. There is nothing here that you couldnt think of if you had a physics or engineering degree, therefore no state secrets of ANY countries.

I think thats fair enough.

Below is my original post, and also swingkids post after it, I shall start by answering his questions, and by posing some of my own.

original post:-
SwingKid,

not a great deal I am able to really braodcast….webwide……safe to say the talk was given by a russian science research institute, a stockholder in sukhoi. that specialise in this area. the material is manufactured using plasma deposition methods in a vacuum, and can therefore be applied in just about any depth needed. a very very thin layer is all that is required to be effective, and generates the required plasma cloud. The electrical draw is also none too large. The system can be switched on and off at will. It can be applied to ANY surface, so long as you can use plasma deposition (for what we saw anyway). Some graphs showing effectiveness seemed to confirm the advantage numerically. One is attached below(note its not symmetrical about 0 degrees? ). Unfortunately the electronic copy of the talk didnt have the video’s included, a major bummer! There are pictures and diagrams of indoor and outdoor test ranges large enough for Su-27’s…paint based work is being followed up aswell, with video of a clear solution being sprayed onto missiles by hand…..also computer controlled painting of RAM on to intakes. allsorts…the most interesting talk from the whole 2 days…

I am sure you’ll get the gist of the graphs, in airborne tests it reduced detection range to 50% and it has been applied to whole aircraft, although they seemed to have some difficulty.

It seems the same people gave the same talk this year too. http://www.iqpc.com

Interesting stuff – thanks, I think, but…

Wha-? We’re talking about a plasma on the flying aircraft, some other kind of RAM deposted by plasma during fabrication, or a plasma deposited by a plasma?

“very very thin layer” of what? The plasma deposits a RAM that generates another plasma? Or a plasma itself generates more plasma?

Are you sure it wasn’t GarryB giving this talk?

Plasma deposition in a vacuum? What aircraft surfaces are normally surrounded by a vacuum? If you’re talking about evacuating a dielectric nosecone, that’s a volume, why the interest in surfaces? Or if you mean a factory-level manufacturing process, hook it up to a power plant, why the interest in electrical draw?

Well that gives a bit of a clue… At least they seem to be talking about hiding antennas like I mentioned earlier, injecting some dose of reality. You’re sure this is a surface treatment, and not to fill the volumes of dielectric enclosures?

The words “screen” and “shielding” are reminiscent of technology used with the F/A-22 radar antenna (which has nothing to do with plasmas AFAIK), but admittedly translated from Russian those words can mean anything, from televisions to condoms…

BTW where I come from, we call that “symmetry.” Very nice.

Hmm, sounds like it. I’ll keep looking.

what.. where.. Whole aircraft? You mean, a Su-27 on a pedestal? Whole aircraft like all the dielectric antenna housings on the aircraft, or the actual skin of the aircraft? Like, the plasma vacuum deposition technique that “can be applied to ANY surface, so long as you use plasma deposition” – what does that mean if they “seem to be having difficulty”?

Who..?

More confused than before,
