    As opposed FalconDude completely ignoring his quote and your rearrangement of it – let’s decipher it word for word, shall we?

    Tell me, is 0.1m^2 a greater or smaller RCS value than 0.3m^2?

    let not rearrange the words ok
    here is the direct quote :

    Thanks to these new design solutions,the T-50 is now ahead of not only all other fighters of the Russian Army, but also foreign models. For example, the visibility of the American fifth-generation F-22 fighter is 0.3-0.4 square meters,” said KRET,while the value of this indicator for the T-50 fighter is between 0.1 and 1 square meters.

    so they did say T-50 is better than anything else, and it’s minimum RCS is 0.1 m2 while F-22 minimum RCS according to them is 0.3 m2

    In the following comparison, do you think stealth figured in the ‘operational capability’ performance metric? I do.

    http://forum.keypublishing.com/attachment.php?attachmentid=223978

    Two different comparisons, two opposing organisations, same conclusion.

    the pictures clearly show T-50 equal to F-35 but inferior to F-22, so what your point? , and operational performance included many things not just RCS, since we know T-50 fly much faster, alot more agile, there must be something hold it back that SAAB only consider it equal F-35. That may be RCS

    All he’s saying is that the PAK-FA’s RCS will be F-22 ballpark………and please do us a favour – no more pages of stealth, radar and RAM theory that you think you understand interspersed with your *explanations*.

    i think you didn’t read it carefully enough , he said T-50 RCS better than anything before, and he also said that F-22 RCS is around 0.3-0.4 while T-50 is around 1- 0.1 m2, that is very different from just saying PAK-FA’s RCS will be F-22 ballpark.
    P/s : are you seriously still butt hurt from the argument we have in like 2014 about VHF radar? seriously wtf?

    At least i gave you the link, not my bad if you do not speak french or use auto translation.

    You could have specific point the time in the video where they mentioned Rafale RCS equal a sparrows . Write down the phrase they used, so that Lukos or anyone doesn’t speak france can put that in GG translate and compared that to what they hear in the video

    the claim is originated from a highly respected engineer and haed engineer on Rafale project. Do what you want with it.
    ?

    Come on, we both know that claim is outrageous, just like when LM claim their F-35 have better kinematic performance than all other 4.5 gen , or when Boeing claim their F-15SE have frontal RCS equal F-35,.etc

    Absolutely false. The pilot is his own name on FB (and i linked the article he wrote). I also copy pasted the dialog i had with him. MAke your homework and check facts before bullying ppl please.

    You said the shot was made at over 20 nm, the pictures in that articles show the shot taken at 7.8 nm, you said the pilots told you so but when we ask you to screen shot the message or posted his Facebook here, you refuse to do that.
    About DDM-NG : you said the sensor have resolution of 1.3 Mp but when we ask for the sorce you said it is classified
    despite all that i still did not call you a troll and only state the reason why i can’t take your words without a source, and you say iam the bully? really ? how am i a bully?

    surprise, link works again. Search for Rafale Confidential on YouTube

    Bah a little hand https://www.youtube.com/watch?v=Mb8W6QUITMc

    🙁 ok, so in previous post you said you didn’t claim Rafale have RCS of Stealth fighter, and in this post you claim Rafales have RCS of a sparrows, are you serious ? really ?
    Sparrow have RCS about 0.001 m2
    so you are effectively claim this:

    have smaller RCS than this :

    Hear hear! It all sound good to me.
    But if you are to play the Devils advocate here, then i suggest you play it right both ways:
    Do you call this a informative discussion/input?

    Ok that wasn’t informative, and it was only meant as sarcasm . But if you pay attention at the discussion from the start : it went like this :
    Halloweene/MSphere : claim something quite unique about Rafale thus make it better than F-35 /Typhoon .

    Lukos : claim something unique about Typhoon/F-35 that make them better than Rafale.
    …… arguing bla bla bla ( both side)

    Halloween/MSphere : made some dodgy claim about Rafale

    Lukos : that sounds like BS, gave me the source or some evidence

    Halloween /MSphere : no, a pilot on Fb told me but i cant give you his fb or i read it from some super secret source and that source is only available to me

    Lukos : make fun of Halloween/MSphere or being sarcastic about Rafale fan

    Halloween /MSphere : you are a troll, making fun of lukos
    ….. bla bla bla both side insult the others

    So I think it totally unfair when you claim Lukos is a troll then claim MSphere knowledgeable. Remember why people consider JSR a troll? he making outrageous claim without anything to back up

    Did i say that with Dedira Rafale would hae the RCS of a F-22? That DDM-NG was better than EODAS? That Spectra make Rafale immune to missiles???

    i dont know about Dedira though, but you and MSphere ( and a few other Rafale fan) did claim that DDM-NG have sensor with better resolution than DAS, and that Spectra will negate stealth aircraft advantage in BVR
    let not play the denied game, I made wrong claim before too, and i have no trouble admit it when people prove iam wrong, so i hope you can be a men and do the same! that way the discussion will be alot more informative for others to read , instead of insulting from both side

    Couple of points:

    1 – Compare the pic of the EO-DAS module with the datasheet for the 4MP L-3 sensor engine.

    The sensor engine is 3/4 the size of a 12-pack of beer cans (by volume). It doesn’t include the cooler, power supply or processor. That makes the EO-DAS module pretty huge. Is there anything other than the shape of the aperture end that suggests that the 4MP module is what’s in there?
    .

    the cooler is right there, btw why do u think it doesn’t have processor or power supply ?

    2 – IRST is distinguished from a targeting pod or EOTS with an “IRST mode” by a much longer focal length and a mirror that moves fast enough to scan the field of regard.

    Long focal length =higher magnification and a narrower angle of view, since IRST often have wider FoV I think you got it in reverse

    You can demand it, no problem with that.. But I cannot give it to you, I gave my word and will stick to it..
    You don’t have to believe it, for all what’s worth..

    if you don’t want to give your source then fine, your choice , but then you shouldnot be angry or call people troll if they choose not to believe you or demand evidence , since we both know you wouldn’t believe us if the situation was reverse
    and the simple rules of any arguments is what is asserted without proof can be dismissed without proof

    No prob… No offense taken.. I’d just like to know, what exactly is my bias now?

    well i would say you have really hateful attitude towards anything related to f-35, and you seem to love Raf alot

    OLS-27 has three FoV’s: 60*10 degrees, 20*5, and 3*3 degrees. Scan rate is said to be 25 degrees per second. I assume OLS-35 is broadly comparable in execution.

    If iam not wrong, you took the info from here http://aerospace.boopidoo.com/philez/Su-15TM%20PICTURES%20&%20DOCS/Overscan%27s%20guide%20to%20Russian%20Military%20Avionics.htm
    correct ?
    Firstly, the maximum range that you see in IRST brochure is the range with smallest Fov 🙁 3*3 in this case) in optimum conditions. if you increase Fov by 2 times, then the range likely decrease for similar amount and so on.

    Secondly, Scan rate was said to reach more than 25 degree/sec, but at what Fov? 20*5 or 3*3?, I think it is at 20*5 zoom, because if the IRST can reach scan rate of 25 degree/sec with 3*3 zoom then that would mean the IRST will look at each 3*3 sector for less than 0.12 seconds, i dont think that is enough time for optical sensor to detect and identify target

    Thirdly, there is nothing stop a targeting pod with adequate software to scan at the same rate with a IRST , they are both optic sensor that work on same principles, to look far they both have to zoom

    Last but not least, what is the FoV and scan rate of AAS-42, OFS, Private?, The France decided the delete the IRST function on OFS, and concluded they are not quite useful, so i assume that either OFS have really small FoV or slow scan rate, or IRST are not as effective in real world as people like to think ( affect by weather, cloud .. etc)

    By contrast, typical targeting pod generally has much narrower Field of View to provide better resolution and range: something like 1*1 in narrow FoV and 4*4 in wide-view. In addition they usually have 20-something degree view for navigation. This is why Targeting pods are likened to “watching through soda straw”.

    Ok so :
    common IRST have three FoV’s: 60*10 degrees, 20*5, and 3*3 degrees
    Targeting pod have three FoV : 20*20 degrees, 4*4 and 1*1 degrees
    4*4, 1*1 zoom on targeting pod are quite compatible to 3*3 zoom of IRST ( for max range)
    20*20 Fov on targeting pod are like the mixture of 60*10 and 20*5 Fov on IRST, the IRST have advantage in azimuth while the targeting pod have advantage in elevation
    So with equal software, i would expected them to perform quite similar

    As said, I haven’t seen EOTS FoVs mentioned anywhere, but I’d guess they are closer to a targeting pod rather than a2a IRST.

    EOTS is basically an internal improved version of Sniper-XR , but Sniper-XR wasn’t claimed to have IRST function while EOTS do. So I think it safe to assume that EOTS have something different that allow it to have IRST capability while the Sniper-XR doesn’t , for example : wider FoV or fast automatic scan rate.

    The front of Taranis is rather a blunt point set forward of the intake unlike the Typhoon (:love-struck:), the lower half off the intake looks flat and not bulged as you would expect for any shock wave management.
    (Long odd are against the nose producing a shock wave and the unusual triangle shaped inlet interacts with that wave by reducing the area of intake the higher up the triangle the wave front hits.)

    That doesn’t preclude an internal ramp arrangement to slow the flow down, however the serpentine bend (like the Typhoon :love-struck:)to the turbine face its a bit tight for all that!! and it would need the spill bleed air to be managed internally i.e. could be piped to the rear to mix with the exhaust gases..

    Do you really need an internal ram or front bum to allow low supersonic speed though ?
    something like F-100 have intake without front bum or internal ram and it can still reach mach 1.3

    Members like MSphere, Scorpion82, etc are quite knowledgeble on many different topics, you should show these guys here a bit more respect.

    I dont know about Scorpion82 , but i wouldn’t call MSphere knowledgeable, dont get it wrong, i dont say MSphere is dumb or anything like Snapfu35 , but he obviously quite bias . And i haven’t really seen where he demonstrate significant better knowledge than other members around here.
    P/s : Nothing personal MSphere, i myself are quite biased too :love-struck:, and i wouldn’t say iam knowledgeable either

    I cannot.. Not that a PM from other forums would persuade you, anyway.
    Nevertheless, take it as a piece of info you can work with.. Or start a d!ck comparison contest instead and scream “gimme a source” in every upcoming message and next time I won’t tell you even that much. If I wanted to lie, I would say at least 4K.

    Ok, think about it this way, If someone here claim that Aim-120 is alot more agile than Mica or that EOTS have significant better range, FoV, Scanning speed than OFS, i bet that you and halloweene will scream ” give a source” otherwise you wouldn’t believe that, and for sure you wouldn’t accept a PM from other forums anyways
    ( just like when you want lukos to prove CAPTOR-E have electronic attack ability )
    So I think it only fair if we also want a source for your claim
