Russians will probably make their new fighters in "plasma stealth" technology.Do you know something more about the advantages or disadvantages of this technology against US technology??Which one is better??

plasma stealth is cool. stupid rushins will never get that because it is too cool for them. we americkans already have this plasma stealth stuff and use it all the time. you just don't see it

well to tell you the truth i have no clue what plasma stealth is

Theoretically, the advantage of plasma stealth technology is that you can take a conventional aircraft that would normally have a high radar cross section but use plasma to significantly reduce the RCS since plasma reflects radar energy much like a current stealth aircraft would. A plane using plasma could be built much like an F-15 or Su-27 for maximum performance while using less expensive materials and being easier to operate and maintain in the field. In other words, you could carry external weapons, wouldn't need radar-absorbant materials, could use standard maintenance procedures and equipment, etc.

Nevertheless, everything I've seen says that plasma stealth is a pipe dream, at least for now. It takes an awful lot of energy to create plasma, even over a relatively small portion of an aircraft The technology to build a power source capable of generating a plasma field yet small enough and light enough to carry on a fighter-sized aircraft is immature, at best.

Another problem is the effects of plasma on other operations of the aircraft. For one thing, communications systems rely on the same RF energies as radar. If you block enemy radar, you may also be blocking the ability of your aircraft to send and receive communications with friendly forces. There have also been attempts to use plasma on engine inlet ducts since these are one of the least stealthy regions on a plane. However, such attempts have created significant problems getting proper engine performance. Your average turbofan engine doesn't particularly like ingesting super-heated ionized gases.

For these reasons and more, I don't think plasma technology will be revolutionizing the aircraft industry anytime soon. External shaping and special treatments will remain the key to low detectability by radar for the foreseeable future.

thank you aerospaceweb, my next question is how is plasma created .

These types of comments are not wanted, Bashing of any type of ethnicity or natinality is not welcome here, the Russians can have anything they want, it all depends if they want it or not.

The Russians I believe were the ones who began to go into extensive experimentation of plasma shields.

Shattered OUT...

youre right. i need to watch my mouth before i start offending people with my simulated stupidity...

duhr... i mean... blast those commies! theyre angry cause we won the war!!!!

part of the time where I was acting like a total idiot. this post does not refelct the true motives and perspectives I have at heart

yea shatteredskies i agree but he was just trying to be funny. and i think he maybe drunk seriously.

It does not matter, I respect the Russians, they are as powerful as the US in brute force, technological, I am nto so sure.

I respect them for their capability to be right behind the US in as many means of advances as possible.

thanks aerospaceweb ),new russian fighters according to their sources will use plasma stealth technology (their fifth generation new fighter),but as I see it could be only russian dream about this technology.What do you think about it??I mean their su-47 and MIG MFI??

if they will not use this techology their new fighter won't be really good because it won't be stealth aircraft???

what do you think about their capabilities of making something that can be really dangerous for f-22???

well i asked this earlier but no one answered can someone explain how plasma is created.

there is some info on www.aeronautics.ru as I remember

Well, plasma is a random mess of molecules with no organization of electrons, so my guess is super heating...

wouldnt a plane that is traveling fast out run the plasma that it is creating? then plasma stealth isnt worth squat

Plasma is defined as a highly ionized fluid. It is usually created under very high temperatures. When an atom reaches very high temperatures, its electrons are excited to a high energy state and escape the attraction of is nucleus. Since the electrical charges are no longer balanced, the substance becomes full of these ioized particles. It takes a great deal of energy to heat up a substance to the point that the electrons are stipped off to create these highly ionized particles. Some examples of processes that create plasma include the interior of the sun, the core of a nuclear weapon when it detonates, the air surrounding a spacecraft during atmospheric reentry, or the air in the immediate vicinity of a bolt of lightning.

I think everyone is missing an important thing here. Enen if a plane could produce a cloud of gas around the plane, it would simply outrun the creation. Plasma does not stick to a plane, and if it did the plane would fall out of the sky as it would stall.

Roniii,
The plasma is apparently being generated in front of the aircraft...
Current experiments covering this science in Russia seem to be using a device that may include a tesla coil to generate little streamers of lightning that propagate ahead of the aircraft, the remnants are blown back past the aircraft in the airflow. It is this "shroud" that not only gives the Russians their claimed stealth but also holds promise for reducing the friction in the atmosphere for hypersonic vehicles in the future.

There is actually extensive research going on in the US on this as well, Princeton University & Arnold Air Force Base in Tennessee come to mind immediately.
However the plasma research in the US seems to be focusing more on hypersonics rather than stealth.
