It was another poster who said a look was given – not sure where that came from.
i was not there, i do not know, i was as i stated merely offering another option.Re answering with a no or not –
Many organisations refuse to confirm or deny anything so that at no time can an answer be inferred nor is a lie ever required, now i dont know what dassault/thales policy is re this, but again its another possibility.
(For a slightly extreme and off topic example- there is nobody this side of outer mongolia, that doesnt know operation Barras was carried out by 22 SAS (note with SBS support and a para supporting raid lest i ruffle feathers) if you ask HM Gov or the Regt if they took part all they will say is NO COMMENT.
have you ever tried to tell a religious nutter there is no proof of the god/s he believes in ?
rafale fanboys are much the same
they have set a very low bar for credibility to such a large claim
if thats the standard they accept, i’m going to email LM and ask the following
1. does the f-35 have plasma stealth through the electrified mesh in the composites
2. does the f-35 use extraterrestrial tech from when they visited us
if they dont answer, this will prove that the f-35 does have it and the rafale fanboys will accept that it does
i’ll let you know if they dont answer
Just think by yourself : Active stealth could mean either AC or Plasma. Given the work done on AC on missiles by thales and MBDA, the carbone jamming pod demonstrator and the effort done on spectrai AC is the most likely option . There is no clue inicating it would be plasma. And Bill sweetman is right to make the lonk between Active stealth and active cancellation instead of plasma.
please show a link where Thales has done any ‘work’ on AC missiles
active stealth can be many techs, not just plasma and AC, as i showed another from this link

which translates as metamaterials
can we stick to one story at a time, we are talking about Air&C article that didnt mention AC
not bill who seems to be the only jurno to make the claim
MBDA is another story and i havent seen anyone call Bullsh*t on them, they have done experiments in AC for missiles
i know the parent companies
The thing is the journalist came to this conclusion, because he asked a question and the engineer didnt reply he just gave him a look.
Now i could be for the reasons you suggest or it could be that the engineer felt it was a really stupid question –
By Bills logic there are 1000s of people who believe air ambulances have machine guns because when they asked if they (pointing at the pitot tubes) are machine guns, the engineer just gave them a look.
(of course if anybody were to ask me – id say yes but thats because im an arrse)
thats like the lightning strike protection on the nose cones, when asked if they are zippers, the answer is always yes
well ya have to have a bit of fun on open day, if ya have to stand around all day making sure no one steals the plane

there are 3 articles ,,2 from bill and 1 from A&C that doesnt say AC
this is the a&c one we are talking about now
LOL 18 years and only bill says AC, that proves the rafale has AC to me
“Active stealth” can perhaps mean several things but what Lyndmeyer and Jackjack forgot is that in this specific case journalists concluded after investigation it was AC.
But it is true that plasma could be included in the generic name active stealth. This was studied for an hypothetic rafale application as explained in an older Air&Cosmos.
Second point : it seems according to DSI that the batch 5 could also encompass stealth improvements but with a more traditional approach (RAM, shapin for fuel tanks etc…)
how do you know they concluded it was AC, i havent seen it said and there is no mention of ac in the article AFAIK
it may well have been plasma or another tech for all we know
i have asked is there an english translation yet or a copy of an electronic edition i can translate
engineers wouldnt use a generic term, they are quite precise in their terminology
they wouldnt even use the term stealth, it would be signature management or the like
re second point, at least that makes sense and something that is needed
I suspect the messh is more to do with lightning strike protection in composites, of course theres nothing to say they cant dual hat it.
although it does act as a faraday cage as well
it is plasma production 😮
its suppose to be a secret please dont google the following
rcs plasma stealth also acts as a Faraday cage
also a version could act as visual plasma screen for cloaking, giving optical stealth
i wonder if they are going to confirm that
i will have to keep reading sweetman to find out
You specifically mentioned “furtivité active plasma.” Of course it came up with a plasma related article. The same article also mentioned metamaterials. Now both of these could be considered “active stealth” in a certain sense. Finding one mention in one French document of plasma and metamaterial technology in regards to active stealth is not terribly convincing, especially when the term “active stealth” usually has quite a well defined meaning in terms of “active cancellation”.
I doubt it is a generic term. BW is French and I’m sure his command of the language is good, no? If you want a second opinion, ask TMor or one of the many other French aerospace enthusiasts on these boards.
As I said, I don’t buy into the whole plasma stealth thing- while it may be theoretically possible, I see it as too much trouble with not enough payoff. As for active cancellation, I see no reason why it would not work fine right now, today, against non-LPI X-band and higher radars or low frequency radars, LPI or not. Especially if you have already managed to reduce returns to a few peak directions. Active cancellation seems like a much easier and more practical way to go.
Also, I think magneto-optic Bragg cells might be related to frequency selective surfaces somehow- perhaps this is what they are talking about? Perhaps there is a way to use FSS or Bragg cells to retransmit a signal out of phase? I’d have to do more research and thinking on this point, but I am very tired right now. Anyways, thanks for the F-35 info- it made me look up adaptive Salisbury screens, so now I have some more reading to do tomorrow.
i went looking for the term being used with other tech and put up the google search link to and quoted just one example
it was very clear what i did
perhaps you could do a search using techs that you like, there are lots active stealth technologies including ac
perhaps bragg cell [is that the same in french] and “furtivité active” and see what it brings up
edit i just did and guess who is the only person in the world that has the same words on a page, Bluewings LOL
i will also look up the mesh tech and see what comes up, it would be worth its own sensible thread, away from the banter
just dont tell the pilots that there are already plans to make them ‘optional’ in the f-35, in a combined 5/6th gen f-35
it will only upset them
iraq, a-stan, p-stan has put usa on a rapidly evolving uav path
come 2020 the mind will boggle
I posted something off topic and I erased it .
Cheers .
fair enough
you still havent acknowledged that ‘active stealth’ is a generic term in french
does this mean you will go quiet for a week and repost the claim ?
The electrified mesh on the F-35 does nothing of the sort. It is related to stealth, but I think it is more of an absorber technology. To actually create a plasma you would need to exposer the mesh to the air.
I believe the F-35 meshing is a specialized absorber technology involving reactive frequency selective surfaces/broadband Salisbury screens.
A google search found this:
http://www.google.com/search?hl=en&q=salisbury+screen+voltage&aq=f&aqi=&aql=&oq=&gs_rfai=The third link is particularly intriguing, as are the citations it lists. The idea is that you can dynamically change the frequency at which your Salisbury absorber (usually a narrowband absorber in passive cases) operates best. Jaumann absorbers are also broadband, and are a similar, simpler passive technology, but I don’t know if they work as well.
now now, thats just what they want you to believe,
of course its plasma, why should the french have all the fun with pixie dust
ps
afaik there hasnt been any official public release of the electric mesh even existing
the only way the one sentence that has become public, it was part of a reference in a power point that wasnt security edited properly before being publicly released
Most likely these
http://en.wikipedia.org/wiki/Boeing_X-45
http://en.wikipedia.org/wiki/X-47_Pegasus
http://www.fas.org/irp/program/collect/uav.htmDragonfly looks interesting.
well it cant be the x-47b as thats being tested by the navy to run with the f-35

i havent seen you left speechless for a long time :diablo:
jackjack :
No . In French we say furtivité active which is a short-cut for active cancellation . Since you don ‘t know our language , I don ‘t blame you .
But please , stop to try to teach us French , merci 😡
you shouldnt tell fibs, i put furtivité active plasma into google and guess what i found

so in french ‘active stealth’ is a generic term that means many things

does the electrified mesh of the f-35 create an ionized gas/plasma,
something like a common tech ozone generator 
Here’s the really violent way to make tons of ozone. It’s basically a thin piece of glass with metal mesh stuck to both sides. When about 5kV is applied to the meshes, a large area corona discharge occurs between the mesh and glass on both sides. This makes a LOT of ozone.
sounds like the 2 layers of electrified mesh that makes part of the composite sandwich of the f-35 to me, but its a secret and i cant tell you

As Mr Sweetman said , it is not French posters who are the source . It is a document from the French MoD allowing funds for the DGA to give a big stack of money to Thalès and their partners to archive active cancellation .
As many posters said (you can trust Arthuro) , so many Governments have allocated money on AC for more than a decade (USA , France , UK , Sweden to say a few) that you just can ‘t troll against it .
except that it didnt say that at all as already has been shown
Since you are an American jackjack ,
see my location and i was born there, unlike you that say they are in france when they are not.
as you said on SP even your mother said you are loosing the ability to speak french when you phone her
let me remind you few things about the B2-Spirit . Its design started in 1979 (!) .
The first aircraft has been delivered in Missouri in 1993 and it did reach OIC in 1997 , 4 years later (!) .
At that time , the USA already knew that a VLO aircraft had very few “peaks” on various bands . So , they started to work on a “radar” (strange but we ‘re mid 80s) to cancel these “peaks” with active cancellation .
This idea was brilliant . 🙂
Unfortunately , we ‘re in mid 80s and the technology was not there . They even had to pay a fee for wrong advertising .Now , we ‘re in 2010 ~which is 20 years later~ and the French GoV and DGA are allocating money and have been doing so for the past 12 years to the AC technology .
And you are … jackjack , an internet poster telling us that it ‘s all in vain …
I certainly don ‘t want to look-down on you jackjack but you should get a grip , really 😉
got a link that it was AC ?
another theory, remember the condensation within the skin, a void was there, what was it filled with ? cold plasma ?
Active Cancellation (AC) is the futur ECM War mode , nothing else .
It will not make aircraft invisible , it will not do any “Klingon Device” .
The goal is to cancel the strongest “peaks” and leave the adverse radar with very low peaks just over the noise level , which can be jammed with the usual means like side lobe attacks and deceptive jamming .Without going again into how radars work , it is already possible to divide a radar range by 4 using the actual best ECM suites . ECCMs are becoming less and less capable because “locking” few bands within a chosen band (X Band as an example) and trying to sort-out the real signals from the jamming is increasingly difficult .
Now , AC can be a decisive advantage against A2A missiles .
I don ‘t need to explain the differences in between a fighter Aesa LPI radar and a missile radar 😉 .
Fooling the latest is way more easy !
Unless the adverse fighter is choosing to use its “fire and forget” missile like a semi-active missile and guide it all the way to the target , I can ‘t see the missile ‘s radar getting a lock …
But the adverse fighter is loosing its “fire and forget” capability , it has to keep a constant lock and it can ‘t turn away .Now , imagine just for a moment that you can force an adverse fighter to come at 30-40km (or less) from you to be able to get a firing solution with a decent pk .
Then , imagine that your radar has been off all the time and only the RWR and the jamming suite took care of the situation at hand .
Then , imagine that your ECM suite is good enough to give you a “kill basket” at 60km for a “fire from the hip” launch with a salvo of EM missiles .
Then , imagine that you have a TV and a LRF to give you a positive firing solution at 35km for a salvo of IR missiles .What you imagine is the Rafale .
The goal of active cancellation is to escape early (long range) the adverse radars by dealing with the very few “peaks” and fool the A2A EM missiles .
Nothing more .Cheers .
why have you back tracted from rafale having AC now ?
active stealth is 10x dearer, harder and just adds to decent shaping for VLO which is the first step in a stealth aircraft
if aussies had a plane that has been for sale for 10 years to lots of countries with no buyers, that even looking at it one can see there is little shaping and lots of protrusions, grills, gaps and with bits screwed on and even poking through the fuselage doesnt make for LO, let alone VLO
i guess if it wasnt making the grade and no one wanted it, i would start to defend my nationalistic pride and joy with all sorts of wonderful things that are secret that really does make it the best plane in the world
i wonder what you would be saying if aussies made the rafale and the french made the f-22 and f-35, would it be the same story ?
they will probably just make one of the ‘black’ aircrafts that are flying public, like the f-117 that was flying for many years before it was wheeled out and made public
then start mass production
it would only be the tool up time needed, a couple of years at the most
