What do you mean by works? If one manages to create and maintain a layer of it around the plane then, yes it works, to the point of real invisibility to modern radars. The question is whether it can be done energy-wise, and where on a plane it can be done, and if it can be maintained.
Oh no.... not another one. Ok. A few basic facts. No working plasma stealth prototype has been demonstrated. The Su-35BM is using conventional RCS reduction techniques. Plasma stealth has almost entirely disappeared from Russian press when talking about the future fighter jet. With those facts in mind.... try to keep this discussion reasonable and sane.

No need to overheat about this, it was just a note that the method does exist in theory, and it does work in theory. Nowhere was it stated that it is being implemented, especially not on SU-35. But if talking about perspective equipment, such as PAKFA or a next gen product, even if it was being implemented on it, I would think "the press" could easily have no access to that information, at the very least it's very possible that it wouldn't. Obviously you and I and everyone else on here draws their info on this from the press, so I would show a little more reservation about what is reasonable and sane when talking about the most advanced military project of such an extremely secretive military as the Russian one.
The only demonstrated use of plasma stealth on a Sukhoi was essentially a plasma screen in front of the radar, which helped to prevent massive reflections from the big MSA. The catch was the radar could not be operated at the same time. Furthermore, it would have no benefit on an AESA radar as it is not mechanical, and can be angled away minimizing any RCS vulnerabilities. As far as plasma stealth envoloping an entire aircraft - that's bull crap made up by Sukhoi fanboys, and then spread around by the unsuspecting.
I know you guys are rational people. My post was mainly directed at kevin123. As for the press, in the past the press routinely speculated about the use of plasma stealth for future fighter jets, including the PAK-FA. In the last couple of years this has disappeared almost entirely. I think it is indicative of something.

Feanor, I speak fluent Russian and I have 5 Russian channels at home. During last air show at the Zukovsky airfield one of the PAK FA engineers gave interview and he spoke that plasma stealth will be incorporated in to the design of the aircraft.

What exactly is plasma stealth anyway? I was wondering what that even is, I've heard of it before.

Forgive me Kevin123 if i find this whole plasma stealth utter nonsens.
Why don't anybody surprize me with even the slightes sign of material on this matter.
Thanks

Those youtube clips have circulated for many years now. Nothing new on the matter.
Why am i responding to this thread at all..

It was said that plasma generator wos designed and tested on some AC. But after this it was rejected.
Plasma field can absorb any radiowaves but not only in direction TO AC but also FROM AC. So it became invisible BUT also it becamr BLIND. That was the main reason of rejection from use this system.

No, it did not say that, not in that paper. It said that they have developed such a device - for minimizing the signal from the radar, by using a plasma screen, and that it's available to be implemented. The time to switch it on and off is said to be in microseconds - off for firing your own beam and on the rest of the time.

I apologize, for some reason I thought you knew Russian... It's a really fascinating paper, a "stealth tech 101". It goes over all the basics of RCS reduction in quite a detail... It was written by two members of the Russian Academy of Sciences, one of whom just happens to be M. Pogosyan - head of Sukhoi... One interesting thing that you can understand there is a diagram supposedly showing RCS of various western aircraft, pretty cool...

I would say unlikely in a near future. There are more reasonable ways they use to reduce missile RCS, like coatings and structural considerations. Plasma use requires a power source, besides, missiles usually travel so fast that it would be very energy consuming to keep plasma around it.
No it doesn't. Plasma stealth requires a lot of heat. Plasma by definition is very hot. Heat stands out to IR sensors like a sore thumb. Therefore, plasma stealth doesn't work, because it doesn't help with reducing the aircraft's overall footprint across all sensors.
