| Tmor , you deserve a response , but as a disclaimer, I would emphasis I have never used confidential info on Strategy Page to prove my assertions and comments.
----------------------------------------------------------------------
Every time I have a doubt on confidentiality, I check on internet and specialized magazines, if info is publicly available or obvious for an engineer.
Moreover I avoid to speak about fields I really have confidential info from my previous works.
Other assertions are based upon simple calculations assuming robust hypothesis and my broad knowledge of engineering issues and defense technology.
I tried also to prove by indirect means like by showing our technology strenghts on US (ASTMP and others) or French sources.
1) FS, you said : "Rafale use a chemical product injection around engine wich mask COMPLETELY exhaust plume on more than 5 meter to help decoy when missile comes." Do you have any public sources about that ??? This is really a scoop !
No, it was published in an article of AirCosmos years ago, even with a photo in IR 12-8µm band.Of course it can be faked or unaccurate as everything which is published on defense.
The fact is that it is theorically possible as IR maskers chemicals are known and used.
2) You said "It is perfectly possible to have pods carrying non stealthy weapon in it, and which would add almost nothing to RCS." By chance, I once read a paper dealing with such a project for Rafale F4... No question here.
....
3) You said "Plasma absorbe EW wave on a large spectrum and this new technology of nineties enable to product external cold plasma in boundary layers to control flow and/or absorb EW."
HUM ! HUM ! I've heard about that before I red what you said. But I was told that plasma reflects EW instead of absorbing it... Then, the only link I know dealing with plasma shields is the "Venik's aviation page" (Google-ize), which tells us that the Rafale is equiped with such a gadget... Is it your source ???
Plasma reflects EW instead of absorbing it: read a science book!
Why we use EW to heat plasma in fusion reactors?
4) You said "Today Rafale has no a single part common with the first demonstrator." Come on ! The engines ! LOL
F404 which are larger in Rafale A demonstrator.Not a single part, even Rafale A was later modified to test M88 later on one side.
5) You said "Well knowing that rafale has a RCS under 0,1 sqm INCLUDING its air to air mica missiles"... Isn't it a fairly optimistic deduction you did ??? Is it a publicly released figure ? Where was it published ? Is this a frontal of all aspect RCS ?
According to Bill Swetman in JED and simple deduction.
It is very easy to achive a 40 RCS reduction (10 by shape and 4 by RAM).
If you read specialized French/US publications, you will learn ten time more than on the web.
For exemple read the article from PY Ufimtsev who is the scientist which has made theory which led to stealth development (well US use Russian basic science sometime!), published in "Proceedings of the IEEE", December 1996 (Comment on diffraction principles and limitations of RCS reduction), or "la furtivité radar" in no 51 of "L'armement" , the review of DGA, or some articles in "Chocs" the review of CEA-DAM.
Maybe you should read what I read on a regular basis: like IEEE Proceedings, Air&Cosmos, NATO Sixteen Nations, Electronic Design, Armada, L'armement, Choc, Scientific American,Matériaux et Techniques, Industry et Technique, Physical review, Journal of fluid mechanic, as also Harvard Business Review, Technovation , R&D management, MIT Sloan Management Review , McKinsey Quarterly, The Banker, Le Monde, Les Echos ...
6) "No US aircraft has 8 distributed AESA antennas for jammer on a fighter." meaning the Rafale HAS 8 antennas dedicated for jamming. Where ? Can you show us ? I think I've an idea where are situated 8 antennas, but not 8 jammers...
"AIr et Cosmos".I have provided an article which said that Rafale is the biggest consumer of Mimic circuitry today in France.And as RBE2 is passive...
7) "Well IR mica with AMRAAM range performance and AM9X maneouvrability and absolutely no warning when coming, will be a shock.It is forbiden for export until now." BIG BIG problem with this assertion you published in january 2005 : Greece has bought MICA IR for the M2k-5. And this was before january. What is the trick ?
Well still forbiden for export in sensitive countries.I mean restrictions.My info was obsolete it seems.
8) You said :
-"Only a F22 can cope today with Rafale and in the future agaisnt evolved versions."
I think so
-"French considered first a nitrogen cooled receptor of Rafale RBE2 [...] but they cancelled it to diminish the price because Rafale is
already superior of anything in world except few US F22."
Air&cosmos (old) for cancellation of nitrogen cooled receiver which was supposed to improve very much receiver gain by reducing thermal noise.
