Subject: Rafale Thread
Softwar    3/9/2009 9:47:25 AM
Started with hope that BW will limit his comments here instead of in every other Fighter thread. I'll start off with:

1 - no export sales
2 - no laser designator
3 - no AESA
4 - overpriced 4th gen fighter

I know Herald , I keep repeating the basics and I 'll do it to no end , or until everybody more or less agree with the facts ...

Or the difference between hot versus cold IR imaging.
 
Until you admit that you don't know what you are talking about , and instead adopt a student's perspective and learn; nobody and I mean nobody, should consider that you have to say as being based on fact.
 
That is not an opinion, its fact. Its based on the technical nonsense I read that you keep posting and your own incompetent explanation of same..

""Or the difference between hot versus cold IR imaging.""
 
I answered that YEARS ago and it was on a Tank thread ....
 
""adopt a student's perspective""
 
I can perfectly do that when I see someone who knows more than I do . This is the why I learned Martial arts , Soccer , kill a man at 400m , make a woman have an orgasm , drive a 40tons truck and most importantly speak my mind .
You come a dollar short . My life experience is my CV and I am proud of it .
You should just acknowledge the facts I provide and discuss about something more relevant Herald .
 
Cheers .

cwDeici , you look like a Procurer who hasn 't got a shadow of a proof . You loose your time in useless bla-bla and you do not bring anything worth to have a look at .
(Furthermore , I truly wander how you can look down on the latest Rafale display ...)

We know for certain that you know nothing now about tanks, either.

That's okay, though. as long as I  KNOW and can prove that you know nothing that you claim to know: that is all that is required of me under the rules.
 
Still think a bore droop sensor is a twenty millimeter cannon or do you want to relive your moment of Leclerc glory?.

I don't mind if you don't.

I had to go back and re-read these last few posts a couple of times, because I couldn't believe Bluewings was actually proposing that the OSF's ranging laser was also being used as an IR missile jammer.
 
BW, you keep begging the question of why no fighter has "this capability".  The answer is pretty simple: the only IR jammers in use are designed specifically to counter common MANPADS threats.  They are designed to automatically detect and defeat MANPADS while the aircraft is landing or taking off, instances when the crew is least likely to be able to react to a missile and where flares are less likely to be effective.  On a large cargo aircraft, or on a tactical helicopter that lands in hot LZs this is worthwhile.  On a fighter jet, devoting that much space and weight to counter such a specific threat in such specific situations makes no sense.
 
And it is, in fact, a very specific threat.  In order for a laser to have any effect on anything more advanced than a simple spin-scanning IR sensor (i.e. what MANPADS use) it has to know the modulating frequency and possibly the carrier frequency required to fool the sensor into misjudging the direction to the target.  This requires very specific knowledge of the seeker being jammed, which is not possible to determine dynamically since unlike RF AAMs, IR seekers do not emit anything.
 
So, no, the Rafale's OSF cannot do this; even if it were capable of detecting and tracking an IR missile fast enough to do anything about it, the laser would have no effect.   Which is why the Rafale uses the same IR countermeasures that every other fighter uses: flares with a spectral emission tailored to match the typical temperatures of the aircraft.

pfff indeed.

you didn't understand the concept and technology then and obviously still don't.

it has nothing to do with technology sitting on an MBT 

the issue is not that you don't know - the issue is now that you pretend that you do and have tried numerous times to equate other irrelevant capabilities into an aviation context.

Yup.  According to this story, "sources indicated that the high cost of the aircraft was one of the factors."  Like I said in the other thread, I suspect this is related to the development cost.  France hasn't funded the development of the uprated M88 or the AESA, and if the MMRCA requirement included a HMS (all the other contenders offer one) that isn't funded either.  All of Dassault's offers to sell post-F3 configuration Rafales require the customer to pay for the development of post-F3 features, so it's likely that the Indians simply balked at that -- especially when all of the other contenders don't come with that additional price tag.

Phaid and gf , you should re-read what I said , then check the links I have provided since I am on SP , then try to read in between the lines with an open mind to get a better understanding . Dassault and its partners will certainly not expose and explain the real capabilities of the Rafale in public documentations , no one does .
Use your knowledge and imagination , try to draw a new picture with the available datas then extrapolate to what the aircraft maker could hide . You 'll find yourselves in the land I walk since 1999 .
 
Cheers .

It's kind of cute the fact that you ignore that you're completely wrong about science and basic facts, ignore it then later make a short post to try to make up for it.
 
You have no clue. You're simply mining for superficial information in a cmples subject then applying it to even more complex subject judgments.
 
Sure Bluewings... you have no sales, your own country is cutting production, your accessories are late out, the ones you say it is superior to has all these things... at least you admit the F-22 is superior. I remember SP said it was nearly equal to the F-35 and one of u Rafale lovers said 'this page is the ultimate judge of debates to be had here' and then I linked to the aircraft combat index on SP.  LOL
 
So sure... go on, believe your plane is better than what every person responsible for defense purchases around the world knows, including your near abroad of Algeria, Africa, ME and your own nation liking it less than before.
 
You're only spending a hobby in delusion.
 

  It seems to me that yourself are in a total state of reality denial.
 
  I would love to see you coming up with any form of hard evidences which wouldn't be the results of the type of commercials you seems to be feeding yourself with...
 
  For a starter, aircrafts performaces and charactyeristics speaks for themself, we are still to SEE any of the version of F-35 performing at Rafale levels.
 
  It doesn't supercruise, It is limited to a dash speed 0.4 lower, have a 10.000 ft operational ceilling deficit and is structuraly limited to 7.0,  7.5 and 9 g when a Rafale is guaranteed to 90% above this for its life time and can easly pull 11 g in case of emergency.
 
  I know tons more about the F-35 and its programe than you apparently do and passed all the gliter and commercial magic you take for granted, all what remains is an overweight, underpowered overhyped commercial CON.
 
  Not everyone ignore what numerous redesign and aeropdynamic problems means in terms of performances or what requierements vs design vs performances means either.
 
  As for the progresses made in Europe on the subject of Optical, Near-IR and IR sensors, you guys are a couple of decades late for your information at the very least.
 
  France have a few recent world's first under her belt to prove this point including the use of dual bandwidth IRST in the West, you being in an advanced state of denial is not helping your case.
 
  Here is a non-updated summery of thecnologies uses in both aircrafts, sources are Jane's and other notoriously informed ones.

  So realy what is MORE "advanced" in an aircraft which uses similar-to-less advanced technologies and boosts lower overal performances PLEASE?

I have been away working , much have been said since my last post ...



 



Since the discussion is very much 'intellectual' orientated , allow me to switch to a more visual experience . I always said that the Rafale was one of the best flyer around and it was an enormous quality in itself . The jet can move in a fast turning 3Dworld faster than most other aircrafts and is probably the best dogfighter around , put aside its supersonic capabilities .



I 've chosen a recent video never posted here so you 'll see how the new Demo looks like  . If you speak a bit of French , the gentle voice is from another Rafale pilot explaining the 6.30 minutes demo . It is an eye ~and ears~ opening :






The fact that this guy is a pilot doesn't mean you're understanding what he is saying properly.

How about you try to get in touch with this pilot and ask him his honest opinion on what you could compare the Rafale too?



If you knew a hundredth of what is necessary to become a pilot even for gliders, you would speak a tad differently, let alone a graduate from a US and French Flight-Test Center like many of Dassault pilots are...
  From where i'm standing i haven't seen any of you with ebough credential to bring anything remotly technical to the debate.
 
  Having a go at Bluewing is easy, coming up wit hthe goods and demonstrating that what you are saying is based on facts is yet another sroty.
 
  So do you carfe to ellaborate and enlight us?
 
Regards, PlG

PierreLeGrand    Herald if you whan science, here is some for you...   5/10/2009 1:42:35 PM


 

Maybe that will help.

 


 

And that might help too. Strictly speaking the flyout of a missile is measured in burn seconds as well residual energy (potential momentum left versus drag, lift, and gravity.)  While you may get repeatable ballistics trajectories from an arttillery piece firing from one spot on the earth to another, that is a static two body problem. Aircraft are different. A air to air missile is an aircraft  that is shoved hard early and then coasts. Even the METEOR will coast through much of its trajectory.  

 

Anyway the missile will not act like an artillery shell, which is why it takes a differential calculus more advanced than what we have to predict exact outcomes for a three or four maneuvering body constantly moving problem. Simple trig will do for that artillery comparison example I set up. So we do estimates for the engagement interval around a launching aircraft and assign probabilities to the PK for our missiles based on known flyouts and potential energy left after burnout. I'm confident about RAYTHEON's figures. I'm also confident about MBDA's. RAYTHEON doesn't have to exaggerate. They don't have to since they have actual war data to back up their marketing and their rockets..

 

Same can be said for RAFAEL, BAE, and Vympel Design Bureau.

 

Note that in the case of MICA and ASTER, MBDA cannot?

 

Now if someone wants to dispute data presented, maybe he can explain first what the simple presented data means or why light still remains light despite assertions to the contrary. A photographer (some of you are camera bugs?) knows exactly why you cannot use a camera or an infrared detector to measure range.

 

Anyway I read this thread for the past week, and its the same old thing as before.


 

If the physics or the technology is against you, its because of an anti-French bias? Is that so? 

 

PROVE IT. Not with brochures and publicity releases, either. Discuss the science.

  If you were comparing AIM-120 and MICA in terms of  burn seconds, you got your little maths and wires badly crossed.
   MICA flies 1 Mach faster and pulls above 10G more than ANY AIM-120.
 
  As for ranges they are a lot more variable then what you allege so simplisticaly...
 
  Operationaly speaking, they are divided into 4 distinctive fractions:
 
  Maximum aerodynamic Range.
 
  Maximum launch range.
 
  No excape range.
 
  Minimum launch range.
 
  All of which are dysplayed to the pilot using HUD or HMDs.
 
  All of which depending on burn time, aerodynamic configurations and characteristics of the AAMs but also the diverse  situations that you illustrated with your picture.
 
  It becomes then obvious that a MICA will have a much longer Maximum aerodynamic range and longer No escape range than an AIM-120, in particular the latest croped-wing versions, by simple virtue of the lift provided by its wings.
 
  This will be even more obvious where energy is echanged with altitude be it in the snap-up or snap-down mode.
 
  As for MBDA you should not be trusting their figures that much...
 
  Here are those (official) from the French armament portal and until recently they were mirrored by that of DGAS the French procurement agency.
 

Performance:

Multi target / multiple launch

Rail or ejector mount launch

Range:< 500 m to > 80 km

Speed: mach 4

Manoeuvring load factor: greater than 50 g
link
 
   So: Minimum launch range is below 500m and Maximum range is (whatever for it is announced) above 80km.
 
   Since i believe every single manufacturer are giving the higher figure i'll assume Maximum aerodynamic range for both AIM-120 and MICAs with a difference, MICA will always have a higher g load capability even at this range.
 
  Reality is nowhere near as simplictic as you guys try to portray it, and what is certain by now is that none of you Rafale detractors have studied the subject in any form of deph and details.
 
  Regards, PlG

PierreLeGrand    Herald you got it wrong again:   5/10/2009 2:14:36 PM
Quote: "A photographer (some of you are camera bugs?) knows exactly why you cannot use a camera or an infrared detector to measure range".
 
 WRONG.
 
Focal plans are exactly this; a range of distances between the focal and the point where the lense is in focus, more to it the depth of field also shrinks as focal length increases for the same apperture, the longer the lense the narrower the focal plan.
 
  This means that even without a range finder which have been used by photographer for decades, one can well estimate the range of an object with a camera with enough precision fo fire an IR AAM.
 
  All you need to know is that the intended target is within range of your AAM and use LOAL mode.
 
  If we have no evidences that this have been done, we know that it is perfectly technicaly feasible.
 
  As for the use of the laser rangefinder with Rafale it was first and foremost for ground targets and gun fire, as is  the tradition with AdA, Jaguars, Mirage F-1 etc.
 
  Then its use was extended for the MICA EM to validate remote firing using Link 16, in the case of a MICA IR this wouldn't have been necessary as its seeker range is way greater than that of the laser used in OSF.
