    the aircraft flew at an incidence of more than 100ยฐ and at negative speeds of ’40 knots without loss of control.

    Yeah , I know that article . Very few airplanes are capable of this .
    (I ‘m still looking for the doc but since I have 4 hard-disks and 2 of them are not plugged in my actual PC , it ‘s gonna take time …)

    Cheers .

    Scorpion :

    You talk about it as if you have seen the HuD video or something else

    I only quoted what the French pilots said .
    Unfortunatly , the SARPA never released any video of the encounter but we have some nice OSF shots . These shots are of interest since they show a couple of interestings details .

    http://i46.tinypic.com/2z6e7sx.jpg

    -1) The USAF used the luneberg lens (visible under the belly) to hide the real RCS of the F-22 .
    -2) the OSF TV imaging quality is astonishing .
    -3) there are 6 different zoom settings
    -4) the LRF is very precise : on the first picture , the F-22 is 576m away , 2100m away on the 2nd picture (and the TV zoom set to “4”) and 644m away on the 3rd picture .

    There is also this HUD picture :

    Looks like a score to me …

    Scorpion :

    A Su-27 is unstable as well, a Su27M is considerably more unstable in any case their nose is being pushed down from a tail slide (negative airspeed) and when performing the cobra (again negative air speed and excessive AoA) they are using the inertia as well.

    I agree but the nose is pushed down because the pilot wants it , not because the aircraft is “falling” this way . Right ? ๐Ÿ˜‰
    Which also shows the excellence of the airframe/FCS .

    Even 25 kt is rather slow and insufficient for sustained level flight or manoeuvring.

    Rgr that wrt sustained level flight but false wrt manoeuvring as the Rafale can still manoeuver at 15kt .

    Unless you regain energy by pushing the nose down and reduce the excessive drag by killing the high AoA the aircraft won’t accelerate at all.

    False , it ‘s where sheer thrust comes into play . It ‘s actually how the F-22 managed to beat the Rafale while the latter is no sloutch in such exercise (acceleration from very low speed) , thanks to the positive thrust ratio (>1:1) .

    That doesn’t mean that you need a full fledged Stuka dive

    lol ! :):p Trying to be funny Scorp ? Well , you are ๐Ÿ™‚ Sense of humour is always appreciated my friend ๐Ÿ™‚

    I seriously doubt and challenge the “it’s falling flat and recovers at 25 kt”.

    But it ‘s the case . Let me find the doc , I have it somewhere . Somewhere …

    Cheers .

    Jackonicko :

    If very low speed agility and post stall capability was more significant than being a niche capability, the MiG-29 and Su-27 would rule the roost in air combat.
    They don’t.

    Says who ? The West NEVER fought top Fulcrums and top Sukhois . The German Fulcrums had quite a reputation , if I may say .

    no fighter pilot worth his salt will deliberately throw away energy by getting that slow.

    You don ‘t understand . The game is to force the opponent to get that slow and there are techniques to archive it . The dogfight is always dictated by the best dogfighter . As an example , the F-16 will try to force its opponent in the slow horizontal fight where the M2000 will try to force its opponent in the vertical plane (Yo-Yo , Himmelman , etc) .
    If the other doesn ‘t want to go there , he ‘ll eventually have to break the fight which is highly dangerous because you usually show your a$$ at one moment .

    In any event, a helmet sight and HOBS missile will obviate the need to get that slow.

    Hopefully yes but when the opponent can set up himself in your 6 after the first turn , you can ‘t fire at it when it ‘s 0.5 km behind you . You would simply loose a perfectly good missile .
    Also , some people are not really aware how busy the pilot ‘s neck is during dogfight ! ๐Ÿ˜ฎ
    Just check that :

    All sparks will burn out in the end

    Scorpion :

    The ridiculous low air speeds (15 kt) are better to be avoided in the first place.

    Sure ! I agree 100% but if it happens …

    The Rafale’s aerodynamics are excellent for such speeds and the FCS is great as well, so it will ensure that you won’t depart, but at such speeds you will hardly have any serious control authority left as the control surfaces become inefficient at such low speeds.

    True but still , if it happens …

    The aircraft will decelerate too such speeds during a manoeuvre and its nose will fall down rather quickly afterwards until enough speed is gained to recover.

    I beg to differ Scorp . With an unstable fighter , it ‘s usually the a$$ who drops first , not the nose . In the Rafale ‘s case , the aircraft fall “flat” and quickly regain authority as the falling speed increase (> 25kt) . With most jets (and airliners) , stall recoveries need to go nose down to regain speed and control , not with the Rafale . The bloody thing can even regain control and authority when going backwards (negative speed) which shows the excellence of the airframe/FCS .

    I also wonder whether that story stems from the Rafale development trials where the edge of the envelope was being exploited…

    Good point , I ‘ll look into it .

    Cheers .

    When the USAF agreed to do mock dogfights with the F-22 against the Rafale , I first said “Fine , the F-22 is gonna get a hell of a time :diablo:” . I even predicted that Rafale could win by a small margin .
    I underestimated how fast the F-22 can regain energy when forced to go low and slow .

    The F-22 managed to beat the Rafale (not by much but still) at the expense of an enormous fuel consumption , after-burner ON at all time even during thrust vectoring manoeuvers . The F-22 even called “bingo fuel” in one occasion .
    It was new and unplanned for the USAF who never had such difficulties when dogfighting against other US aircraft where the F-22 always prevailed with ease .
    What I would like to see is the Rafale doing mock dogfights against late SU fighters . That would be interesting ๐Ÿ™‚

    Cheers .

    Few good posts from Shiv , Nic and Scorpion , good job Gentlemen ๐Ÿ™‚

    I don ‘t think we need to argue that the Typhoon enjoys an edge at high altitude/high speed . “Up-there” , it ‘s its playground (like the M2000) .
    But the Typhoon is a very good dogfighter too (like the M2000) . It is just that the Rafale is an exceptional dogfighter and very hard to beat when the altitude/speed drop .

    As pointed out by some , the Typhoon has restrictions where the Rafale hasn ‘t . While they are both delta-canard fighters , the airframes are vastly different as well as the flight control systems .
    As an example , a very agressive Rafale jock had to go as slow as 15kt (!) to gun a M2000 driven by a vindicative instructor and without loss of control or authority .
    Something a Typhoon can ‘t as it would depart and fall like a stone , it is why it has ALSR (Auto Low Speed Recovery) :

    http://i49.tinypic.com/6yfio1.jpg

    The Rafale can ‘t depart , even at negative (!) speed . It has a lot to do with the close coupled canards , the wing shape and the very permissive FCS . The Rafale has lift for sale ๐Ÿ˜Ž

    Cheers .

    The last 3 pages , I didn ‘t learn anything . Nothing , nada , zero ๐Ÿ˜ก

    This Rafale thread has become (again) a pi$$ing contest mostly based on BS and nitpicking details , from both sides .
    It has to stop , I mean it . ๐Ÿ˜ก

    Set-up a new Typhoon vs Rafale thread but stop polluting this one , thank you .

    Now , regarding the Mica (since it is Rafale ‘s main missile , so it ‘s on topic) , the IR version has some tricks up its sleeve when compare to other IR missiles .
    The range advantage being only one of them . Its autonomous and clever cooling system is not subjected to time restritions and is working at all time making it a very useful short range IRST/FLIR . This in itself is giving the pilot(s) an earlier LOBL than any other IR missiles as well as participating at the overall situational awareness during the whole mission .
    Wrt the range acquisition , it is classified but we can expect around 20km and if the opposite fighter is showing his a$$ (tail chase) the Mica will hit when Asraam /Iris-t/R-77 will not by lack of range/energy .
    I hope that you all see the edge .

    BVR combat starts head on most of the time (as long as both sides are well aware of each other) but right after that , both sides HAVE to manoeuver to evade the missile barrage and/or to get in a better position for WVR engagement . In between , there is a 1-2 minutes lap of time where the IR Mica is shining : it can hit at 40km+ with a good NEZ and it is passive .
    I hope that you all see the edge .

    Remind me , when was the last time a BVR EM missile killed a real enemy at 50km ? Years ago …
    Even the “mighty” Amraam did fare rather poorly beyond 30km . At that range (30km) , the Mica will hit the target before the Amraam because of its better acceleration which is , AFAIK , unmatched . From the rail to 20km , the bloody thing is a dragster and leave in the dust many other AtoA missiles .
    It has chord wings to extend the range to 60km+ .
    Because it has thrust vectoring , some people think it is mostly a WVR missile but in fact , it is like the Rafale : it is an “omnirole” missile .
    A real winning combo and you can even switch the EM head for an IR head in minutes : it ‘s the same missile with the same interface . ๐Ÿ˜Ž
    I hope that you all see the edge .

    Also , one should never forget the “fear factor” a pilot is up to when facing an enemy capable to fire passively a passive missile at 30km+ , which is a BVR situation . The enemy also knows that the same missile can be fired (actively) from longer range , just increasing the “fear factor” , knowing that the end game can ‘t be jammed with ECMs .
    A medium range IR missile (also capable of real good dogfighting) is a threat not to be taken lightly . The end game is just too dangerous to mess around with , even at short BVR range (30km+) or medium BVR range (40km) .

    To make it short , the Mica is a powerful weapon from 500m to 60km+ and the others know it .

    Cheers .

    Scorpion :

    Leavin everything to the missile is possible, but if there are multiple contacts you better ensure you lock onto the right target which isn’t necessarily a given if the seeker is doing search and acquisition on its own.

    +1 .

    I’d take a somewhat lesser low speed manoeuvrability with an HMD instead and a dedicated IRST/FLIR senor rather than a missile IR seeker.

    I ‘d take the more manoeuvrable aircraft with IRST/FLIR and the IR missile . ๐Ÿ˜€
    Wrt the Captor-E , its planned performances should make it a better radar than the RBE2-AA . While the Thalรจs radar will do its job just fine , the Captor-E is more promising .

    No IR Meteor is planned so far and I regret it but who knows …
    Anyway , it ‘s going to be a hell of a EM missile and it will spread a “Fear Factor” amongst the opponent which is good since that they ‘ll be on the defensive from further away than now .

    Cheers .

    Scorpion :

    In the eyes of an utterly delusional and biased die hard fanboy like you yes.

    Don ‘t make me laugh Scorpion , you perfectly know that the Rafale is a better aircraft than the Typhoon overall and there is no need to go personal .
    While I have a great respect for you and for what you post on various forums , you must control your temper a bit and look at the big picture when you read me . ๐Ÿ˜Ž
    Saying that I am “utterly delusional” is wrong and remember that I have been 7 years in the Air Force and I know what is good and what is not when it comes to hit the enemy while preserving your own life and material .

    f-35pwiii , nothing of what I said in my last post is false but feel free to explain yourself instead to just go “lol” .

    I can assure you that I have a good knowledge of the Typhoon and some posters here know it . I don ‘t speak lightly and while I have my own opinion (like everybody else) , my posts are mostly based on known facts and/or numbers . Today , May the 20th 2012 , the Typhoon is not a multirole fighter yet as it still lack some capabilities and its armory is minimal .
    For the past 15 years , I have been saying that the Eurofighter is a mistake .
    It ‘s not a bad bird (far from it) but it is too much AtoA orientated and it ‘s not a Navy fighter . Today and for the foreseable futur , the carrier capable aircraft will become more and more important and they truely need to be multirole . Since WW2 , Navy fighters have been the spearhead of many Nations/Navies (USN , RN , MN) and it ‘s not going to change anytime soon .
    Yesterday , the US Super-Hornet was the best Navy multirole fighter but it is not anymore . The Rafale is .
    The Typhoon was designed to fight a hypotetical War where the Rafale was designed to … fight . Note the difference and think about it , my words are not empty words .

    Cheers .

    Shiv :

    in the end the things that matter most are areas like weapons delivery, because that’s what you send your jet to do – deliver weapons.

    Exactly ! Bangs for Bucks is what matter and the Rafale does a lot more (than the Typhoon) for a bit less money .

    “Deal ! Where do I sign ?”

    The Typhoon is a ground based M2000 on steroรฎds with good multirole capabilities (like the M2000) while the Rafale is a carrier capable omnirole fighter . If we forget for a moment the avionics and look at other features , like aerodynamics , anti-corrosion/salt materials , airframe robustness , low speed handling , fuel management , range , weapon load , available armory , the Rafale is ahead . What counts is to hit the enemy hard and to come back alive .
    If you can get that for a decent amount of money , you sign the deal .

    Cheers .

    Obligatory :

    It ‘s easy to see where you stand just by reading how you “judge” some people .
    He admitted that he had a “brain fart” with numbers and percentages but his point of view is valid , as I pointed out .

    No need to bash the man , he did provide some very good insights .
