Russian plasma stealth fighters

Writing by Tolip on Wednesday, 3 of October , 2007 at 2:30 pm

First developed by the Russians, plasma stealth technology is also known as “Active Stealth Technology”. Plasma stealth is a proposed process that uses ionized gas (plasma) to reduce the radar cross section (RCS) of an aircraft. A plasma stream is injected in front of the aircraft covering the entire body of the aircraft and absorbing most of the electromagnetic energy of the radar waves, thus making the aircraft difficult to detect.

There are few experimental studies of plasma’s effect on RCS. One of the most interesting articles was published by the Institute of Electrical and Electronics Engineers (IEEE) in 1963 and described the effect of plasma on the RCS of aircraft. The article entitled “Radar cross sections of dielectric or plasma coated conducting spheres and circular cylinders” was based on the data offered by Sputnik, the first artificial satellite launched by the Soviet Union on October 4, 1957.

While trying to track Sputnik it was noticed that its electromagnetic scattering properties were different from what was expected for a conductive sphere. This was due to the satellite traveling inside of a plasma shell.While Sputnik was flying at high velocity through the ionosphere it was surrounded by a naturally-occuring plasma shell and because of it there were two separate radar reflections: the first from the surface of the satellite itself and the second from the plasma shell. If one of the reflections is greater the other one will not contribute much to the overall effect. When the two reflections have the same order of magnitude and are out of phase relative to each other cancellation occurs and the RCS becomes null. The aircraft becomes invisible to radar.

In January 1999, the Russian news agency ITAR-TASS published an interview with Doctor Anatoliy Koroteyev who talked about the plasma stealth device developed by his organization. Doctor Koroteyev was the director of the Keldysh Research Center. There have also been claims that in 2002 the Russians tested a plasma stealth device on board a Su-27 and RCS was reduced by a factor of 100.

The Keldysh Research Center has created a plasma generator that weights no more than 100 kilos, thus making it possible to be fitted on board most tactical aircraft. Current stealth technology uses radar absorbent materials (RAM) and angled surfaces that don’t reflect radar waves back. This constitutes as a main drawback, since an alteration of the airframe has negative effects on the flight characteristics of these aircraft. The third generation stealth technology F-22 Raptor seems however to be an exception since it is both a fast aicraft and very maneuverable.

By using a plasma generator the aerodynamic characteristics of the aircraft do not suffer which in term means that the payload is increased making it more effective. The use of this technology offers the benefit of not having to carry the payload internally to be able to fool enemy radar. The Sukhoi Su-35 and the MiG-35 (both upgrades of Su-27 and MiG-29) are the first to benefit from this technology.

One of the most interesting russian fighters to benefit from the plasma stealth technology is the MiG 1.42/1.44 also known as the MFI (Mnogofunktsionalny Frontovoi Istrebitel - Multifunctional Frontline Fighter). This new aircraft is a fifth generation air-superiority fighter, a rival for the american F-22 Raptor. Both aircraft have the same supercruise capability as well as thrust vectoring for supermaneuverability (a capability to fly at supercritical angles of attack, at increased level of sustained and
available g-loads and high turn-angle rate, which require a greater thrust-to-weight ratio and improved wing aerodynamic efficiency). This aircraft may prove to be a milestone in aviation, as so many russian aircraft were before.

Here are some videos of the MiG 1.42/1.44 and MiG 29 OVT (MiG 35)

Plasma Stealth…..Let’s take a look at this logically.

FIRST, Plasma is superheated gas, that is what MAKES IT PLASMA. That would make the aircraft in question stand out like a sore thumb on ANYONE’S INFRARED targeting systems.

SECOND, If Plasma Stealth works by NULLING the RADAR signal of incoming/enemy aircraft…well here in lies the paradox. If the Plasma Stealth equipped bird trys using RADAR…his outgoing signal will be drastically reduced. What is left will hit the target..bounce back and be even FURTHER REDUCED TO NOTHING coming back through the field….making any of his targets invisible. So if he is going against an F-22 or F-35 which are already Stealth….well, he just made them even more Stealth. Plasma Stealth would be a hindrance to the user more than a help.

Red stars always win, did you knew that the stealth theory was developed by a Russian and America based his stealth planes on that tecnology, the name of this person is Pyotr Ufimtsev and did you knew that the Russians valued that this isn’t good for a plane because it’s looked by a radar at low frequency, remember yugoslavia and the f-117??

Something else, did you knew that the F-35 has the technology of the yak-141 a plane from the 80’s? and they show you that as the most amazing and new technology. America has not enough cientistics to make what the russians make have you seen the Topol-M? In the west it was considered impossible in ballistics. Bye to the DAM.

Maharba…Yugoslavia shot down ONE F-117, ONE! NATO flew in and out of Yugoslavia using the same route every time! Considering how many thousands of sorties were flown, shooting down one stealth aircraft is pathetic.
Great looking plane above, but thrust vectoring was first demonstrated with the X-35 at the Paris Air Show years ago. More evidence of Russia checking out the US’s tech and copying it. That MiG looks like a cross between an F-16 and F-18. Smart idea when you think about it since they don’t have an abundance of money. Hell, even Putin was saying if they are lucky and smart, they MIGHT have the 6th best economy in the world down the road.

To,
HAT1701D

The passive seeking radars of MIG 35,Sukhoi 35 and Sukhoi MK1 enable the pilot to see the targets clearly because the functioning of the plasma device doesn’t interfere with the cross section of the plane’s radar.

(Plasma is not super heated gas.We all have plasma.If it were to be super heated,we would have melted.No life would have existed).

Plus the system draws in cool air and cools it further to spread a cool film of air around the body of the aircraft.So the plane is difficult to be sighted anyway.This naturally makes the plane’s radar more receptive and powerful.In other words,this plasma stealth system doesn’t make the enemy more invisible and doesn’t make the aircraft that uses plasma stealth more exposed.In this case the enemy stands exposed like a black sheep amidst a herd of white sheep.

There are different meanings to the word plasma. One of them is the one you talked about, liquid substance inside us (like blood plasma, cytoplasm, etc). Plasma discussed here is the ionized gas. They just happened to have the same name.

To: HAT1701D

While true that one way to create Plasma is by heating, Plasma is not always very hot, since there’s even ultracold plasma on temperature of 1mK or lower. Well, fluorescent light generates plasma and they’re not that hot I think - though touching them is still too hot for my hand I suppose.

As a matter of fact the russians don’t need the Stealth. As in the war on the Balkans US stealth fighter F-117 was intercepted and hit by a 1960-1980 weapon system the radar used to track the “Invisible” plane was a 30 year old The Russian 1R13 radar system.
So what need of a Stealth super secret material and design when you will go down by a “Stick”…

“Krasimir” the radar on that missile didn’t see the plane it was a blind shot. Read G’s post, “NATO flew in and out of Yugoslavia using the same route every time!” If you know where they will be and when they will be there you don’t need a tracking device to get them.

Anyway, I just wonder what happens when plasma goes into the jet engine. Most plasmas are hot and all plasmas are ionized (not blood plasma that’s a different meaning of the word) and I’m sure that would affect a lot of things.

Regardless, what happens in a cross wind? Does the cross wind blow away your plasma radar shield? Does the jet have a giant electromagnetic field (read: easily detected) surrounding it to keep the plasma next to the airframe?

The more I think about it, the more ridiculous this all sounds. Silly propaganda :\

Well number one: Mr Ufimtsev is the guy behind current US stealth technology. He published a book back in 1960’s regarding this subject, and that was actually a physics text book. Soviets never went on using that technology since it was too expencive and very unreliable. So please do a search on stealth and Ufimtsev,it was also featured on history channel, as for proofs please note several f-117 that were shut down in Ugoslavia.

Second of all: American engeeneers that have to deal with stealth technology have Ufimtsev as their Idol, and indeed they had a chance to meet him personally in 1990’s but to their dismay he layed out a simple solution to his own alogarithm that is used today in american stealth fighters, this method renders the whole technology absolete. Again coming back to reason why Soviets never applied this technology. Russian aircraft and air defence systems have been using counter technology to detect stealth as soon as Americans built 1st stealth aircraft. Look at production date of Mig-31 it was designed to intersept SR-71 and still is the fastest and highest flying plane.

As for plazma technology please refer to Janes (publishing leader on war technology and news, also most up to date database on military subject) According to Janes….. back in 1980’s several American aircraft carriers were overflown by TU-95 Bear (and that is a big bomber)that were not detected until they came in to visual range. Also later several fighter jets were flying over US navy vessels and again were not detected until seen. This caused a lot of stress on people in pentagon and a lot of pople were fired. Later it was published again by Janes that conclusing was that Russians did implement plazma technology on their bombers and fighter jets. This information was never made public but is available in reliable military publishings.

I hope i made it clear what is what. Yeh take a look at 1997 issue of newsweek and time magazine. There is 2 page article about F-22 raptor and right after that white on black 4 page article about Su-27. That would clear up soem issues about American stealth and brute Russian approach to things.

Besides please note that F-22 entered production 5 years after Sukhoi entered service. F-22 is equiped with russian ejection seats, and it’s thrust vectoring is limited only to vertical vectoring where mig-29, mig-35 and su-30 su-32 su-35 su-37 have ability to vector in any direction.

Dude the F-22 has the engines copied from the russian jet fighters and they only started using them now but in Russia they have perfected them

the maneuverability only can go up and down left or right on the F-22 both sides of the back of the engine at once while on the Russian fighters including MiG-MFI they can flip one side up and the other down making it much more maneuverable and easier to do barrel rolls and with the plasma stealth technology on board that fighter, that becomes one hell of a fighter with cosmic speeds making it able to fly around the world in a couple minutes that’s right minutes not hours

all this while i thought the USA were far ahead of Russia, in terms of jet technology. reading these comments, i am convinced that in good economic times Russia can do more than the USA. Russia can partner a rich countries like China to create jet planes which can rival or overtake the F-22 or the Euro Fighter.
Question: are the Russian stealth planes in use or under construction?

as of now, they are still in the development stage or so they claim. you might not know whether they already have it. besides, deception is a key to any war as the art of war states. as a forecast, i would say that fighters or strike aircrafts may even push further to the ionosphere to be even more effective in evading detection.

You guys are talking way too much on things you have only heard about.The Russians didn’t develop any stealth fighter yet because they have seen its disadvantages in development costs, maintainability, price, etc. already at the American aircrafts.Me if I was an expert in such a domain I would rather develop new generation radars than stealth airframes.Besides the plasma stealth I’ve heard rumors that the Russians are considering a new type of radar capable to detect an aircraft by the turbulence it creates or the broken natural airflows by the hot jet exhaust, so radars are evolving as well, not only the airframes, I don’t know if the Americans did consider this before stating that “the F-22 can’t be matched by any known or projected plane”.Regards

WTF man im from Macedonia which was part from Yugoslavia,what kind of an idiot you have to be to think that someone will shoot a missile in an empty space,hoping it will make the shot at the right time so that you can shoot down a stealth aircraft.Its like shooting a sniper rifle and youve been LEGALY BLIND! trough out your whole life.So please RANDOM GUY dont make such a stupid comments,please for fuck sake.To make long story short the F117 actually showed on te radar,how i dont know? but it did so they stick an old ground to air missile up his butt,try to flew the mighty Raptor F22 trough a field that is surrounded with the newest Russian radars and SAM’s.If USA would have to invade,or bring peace,whatever you guys call it just to justife your cause for going into war,and that country surpose to be a 3rd world country equiped with the most advanced Russian Radars and SAM’s,I’ll guarantee you that USA will chicken out!you dont get iven near close to that place and not being shot down,so tuff luck.
Another thing do you think that russians will come out with what they claim Plasma stealth 5th gen fighters claiming that it will challenge the USA’s 5th gen fighters or surpass and after so many claims and finally signing a deal to produce them with other partners they will FAIL ON THE END?
Failing means losing bussines for good do you think that thats what the Russian scientist were doing while working on the plasma stealth?
Yes they were eating MCDonalds instead of doing their job,this bashing bullshit over the russians its incredible,but when they bring the punc it will be powerfull I guarantee you that.The only time Russian jets were shot down by USA jets was during middle east war back in the 80’s and in kosovo,not iven one mig 21 or 29 was properly functional due to the goverment not having funds to maintain them.The MIG 29 serbian pilot that got shot down by an Swedish F15 or F16 not sure which one he flew knowing his mig has no functional radar,it means he flew blind knowing he will die,he did that so that as a captain he didnt want to send younger kid to die!!!!
India vs USA friendly dog fight that was held in India,blue force F-15 vs red force Su-30 and Mig-21,USA lost by India 10:1.Lets see what the Russians come up with,and no need for waithing they will surprise the world again.

Friends,

1. The story of F-117 in Yugoslavia is secret one on both sides, because the local commander of the small air defence unit was an ethnic Hungarian engineer(difficult fact to swallow for the Serbs). However the guy has made a large interview in Hungary. Needless to say, it was not a blind shot, he organized an all-day disciplined and well prepared radaring in his small local unit using their outdated but reliable Russian stuff. Suddenly they discovered the Amies and they immediately shot them off. So simple is it. In the third word however (Iraq, Syria, Iran)local commanders are simply undereducated and passive to organize such a high-level 24 hours service. (The guy told later that he considered the detection of F-117 a professional challenge :-)soundz pretty European.

2. The Chinese took the F-117 to their Belgrade embassy for research (thats why it was bombed by US). Anyway, now China has the technology and the new materials to build its own (perfected) F-117. They don’t rush with this project.

3. The reason why China is not mass-producing aircraft carriers and stealth bombers, is that there is a long-lasting and bitter debate about their use in the highest mlitary command. Late 2008 a Russian SU-bomber (equipped with cutting edge “plasma technology”) flew over a US aircraft carrier in the Pacific (ask Google), practically showing that aircraft carriers are swimming coffins nowadays.

4. I am from a free and reasonaly rich European country previously occupied by the Soviets. We don’t have any nostalgy of the past, but one has to admit that the quality of Russian basic research is vry high indeed. The actual development (military or civil) is the weak point. Now lets see what Putin can finance for its army (falling oil prices) and what Obama can give to the Pentagon (economic meltdown)…..China…well…they seem to be the winners of the game, in the short term at least.

5. Finally, technology is not everything. When US faced first world nations (for instance, poor communist countries like China, Vietnam, Korea with proper mass education, industry and basic infrastructure) the army was defeated. Whenever USArmy meets third world nations (rich oil countries without mass education, industry and proper civil infrastructure), the green necks win the war. Educated, disciplined people with high moral are victorious against the finest technology.
