He did have some good conversations with Jo Asakura(sucks I do not see this user alot either last time I saw him was the announcement of kinzhal for mig-31) back in the days when I was lurking these threads. Is it because he has this jinguistic approach that makes him appear he has a strong bias? Even if he does I dont think there is any faults I can find other than explaining his reasons for favoring US aircraft?
    You never know, if you visited the Indian Forum before it was closed, you'd understand this scorpion guys aversion for sampax, I believe that he never really recovered from being demonstratively proven wrong claiming Typhoon used canard in the roll axis, Picard, I don't know, but apparently everyone kicking the US/British fighter mafia in forums is considered as a threat.

    Anyway, that's what happens when people run out of proper argument and i'm sorry to say but there are some guys who should really not be writing this stuff, because they understand zilth to it.

    Am I? Trash would be defined by personal attacks, complete paranoia spreading, smear about some characters you knew once and spamming a topic with irrelevant B.S about another A-C, not to mention forum legends and other form of flaming B.S, I will have seen everything.

    So, Picard, Sampax, this other guy toocool knew once, make up your mind. Hilarious, btw, explain to your pal the implication of making any canard delta using those surfaces in roll because even so he posed with a false GAF uniform in front of an E-F Typhoon it didn't look too good, I read the topic by curiosity, but this attracted my attention. LOL!

    That sounds about right. If only we can group JSR, KGB, ActionJackson and ThincanKiller in one thread so they can't flood the forum with trash

    but in your fanboy world, it is not similar, of course unless it is a close couple canard like your pet Rafale, it must be not thing exceptional, i get your agenda


    No agenda here, one has airflow characteristics of the close-coupled canard and is aerodynamically stall and spin resistant, the other is not, and L-M also never claim that it is, on the other hand, when they mention loss of control and vortex brake down at high AoA, you should logically pick up on this because it is a huge clue on A-C level of control, but not everyone has the right knowledge base to do that, granted you came back for more.

    Within AoA and spin testing, not PSM as such, and at this level EVERY single A-C which is put through those tests and come out of spins possesses those qualities to a degree, depending on the A-C, it doesn't make them "PSM capable" or else, a Jaguar would be, it means they have enough control in post stall to get out of a spin.

    AGAIN: Increasing spin yaw rate, stopping it, using ailerons elevons and rudder, is not unusual, the reason why they don't use it operationally with some A-C is explained by the conclusion of the DRYDEN X-31 pilots, do you want to read it again?




    Originally posted by garryA View Post

    F-16 doesn't "start" a 120* yaw, it departs out of control due to a forced entry in a flight regime and part of its flight envelop where it is prone to departure (transonic/asymetrical load), AGAIN, you still haven't got the meaning of the word control, or controlled flight, and yes, if it recover from it, at least it has the right level of control for it. btw, close-coupled canards also are more resistant to departure in this flight regime with asymmetrical load. Tada!

    Whatever, you can't even figure that you don't need to be post-stall to do that and more to the point that you need to be able to use the same controls to get out of a spin .

    So Cobra, Pedal turn or else, I believe that you still can't understand the difference, here it never was about a Cobra but controllability needed to get out of a stall and spin, what control surfaces you need to use to get out of a yaw spin, since you have no clue, you can't figure all A-Cs which go through those tests successfully demonstrate the same level of controllability to an extend and in some case MORE, like demonstrated by the Gripen PSM, and no it has nothing to do with F-16 loss of control, it was a fully controlled PSM.

    I don't try to prove anything, you do it well enough, you proved time and time again that you know too little about the subject to figure what is what and consistently mistake subject (loss of control, vs fully controlled PSM, high AoA vs PSM) to the point of confusion, therefore when one pilot tells you B.S in airshow, you swallow the little ostia, leave your capacity of being critical in the basement, don't ask what AoA did they turn? And then pop in Rafale topics spamming with documentation you haven't come anywhere close to comprehend, do we have to be impressed?

    Let's see: Rafale can't be stalled, Rafale is M2.0 capable. Yeah.... Right.

    Coming from you I take it as a compliment, at least he knows his ABC even if the most advanced stuff eludes him because apparently he haven't been through the same training than I have, including aerodynamics, but anyone who has can understand what I write, you don't, and I can tell why.

    Never, meaning the FCS needed to be twicked because otherwise it would prevent departure which is not exceptional for a FCS since it is designed for the purpose of keeping the A-C within its controlled flight parameters, it doesn't mean that the aerodynamic of the A-C make it spin-resistant, there is NO mention there of the aerodynamics preventing departure on its own, but FCS is mentioned and it was not turned off.
    In Rafale spin departure test, the pilot have to disable some mode of FCS so he can put his aircraft in a departure
    In F-35 spin departure test,the pilot have to twitch the FCS so he can put his aircraft in a departure

    Another example: What one trainee pilot will learn even before flaring an A-C and landing, stall characteristics and the importance of speed recovery, speed recovery procedure, which control surface works and up to which AoA on your A-C, when their role crosses (rudder instead of ailerons), not to use ailerons in the stall as not to increase loss of control by stalling one wing further which would trigger a spin.
    ALL OF WHICH allows you to mistake high AoA for PSM, take those basics a step higher, you end up triggering spins, increasing the yaw rate, stopping the spin using the same controls as Boston Combe did with a Jaguar in yaw spins at 100* AoA, NO PSM there.
    Simple, but too high end for you.
    in fact you have NO clue what the difference between departed and controlled flight are..

    So I reiterate: There is no video
    In other words, after 3 pages of trolling, you can't provide any evidence

    Leave my mum alone, she had brains.

    Do you realize that you try to pass a 10tons fighters for a light A-C and went from " cannot be stalled to "the only way to stall it is what maneuver I pass on my DR"? How ridiculous you sound doesn't hit you between the ears yet but one day it will, when you'll know more about stalling an A-C for example...

    Speed generates pressure which generates lift, come a point where there isn't enough pressure generated and therefore not enough lift, as I said, regardless of the amount of airflow remaining on the wing, or else, one couldn't stall an A-C in a 0* AoA and vertical climb on speed only, which is what I have done, and there is no substitute for a real life demonstration of those principles, reasons for advanced manoeuvrability courses to exist in the first place, looks like you need some of those, because Hammerhead in my time was not qualified as Aerobatics.

    And btw, the L-M videos graciously spammed on this topic demonstrate how their flight test team did it, no Hammerhead but vertical stall, which is part of it.

    And yes I have done it hundred of times, not only because I liked it (it's actually quiet fun), but also because it was part of my training, with and instructor or solo on different type of A-Cs, I just fail to understand how it was not part of yours.

    Since you delude yourself into thinking that there is only one way to stall an A-C and completely failed to figure out that a Rafale is NOT your DR400, which would produce more lift at low speed anyway, that without speed you have no pressure then no lift, I am not holding my breath and frankly I couldn't care less, because whatever Rafale close-coupled canard qualities and regardless of how much I might like the A-C or not, the last thing I would claim is that it can fly by the definition of the word flying at speed where pressures and lift are way too low to keep it airborne.

    I said it could be stalled you were adamant it couldn't up to the point you realised you were wrong, which is a progress.

    2) You still fail to demonstrate PS Maneuvers testing phases by L-M flight test members simply because they do not mention them, quiet the opposite.
    You are the most shameless liar i ever talk to. There are two phase of test, the first one is post stall maneuver while the second one is intentional departure recovery, yet you intentionally blurring the two so that you can interpret F-35 test as purely spin recovery test.
    Unfortunately for you, the evidence are overwhelming

    and maneuver to get where you want to be in relation to your opponent, so that will be a maneuver enhancing capability that the F-35 has

    All you demonstrated is: You don't know what post stall maneuvers are, read the definition of the word maneuvers first.

    You ignore FACTS such as, the mention of loss of control vortex breakdown, F-22 being better at it (but they still never use PSM in combat), ALL A-Cs in this field go through the same flight testing phases and use the same "manoeuvrability" capabilities with the SAME control surfaces to get out of yaw spins, test includes increasing yaw rates and oscillations with use of some control surfaces, so according to your fuzzy definition, a Jaguar is capable of PSM.
    High AoA and spin recovery procedures and nothing 3rd and 4th gen A-C did not do
    Can a jaguar perform a pedal turn ? nope. Did the manufacturer of Jaguar said it can maneuver in post stall region to give significant advantage in air combat? nope.

    Quote Dan Canin F-35 test pilot:

    There are several different phonomenon that occur when you get high Angle of attack.

    First of all, as the angle of attack increases, the flow which is normally very smooth, starts to separate from the surfaces and you got a lot of turbulences.

    First we had the basic controlability problem of high angle of attack, and flow separation also the challenge of having relatively low dynamic pressures.

    You put the A-C into a spin, you get the A-C established into that out of control condition, and then when the controller calls, we add a lot to that condition
    I like how you intentionally skip out part of the video and hoping no one notice what you are doing, why don't you quote the whole part? oh yes, because it doesn't support your nonsense claims

    So according to an "expert" like you, pilot intentionally depart their F-35 out of control so that they can perform pedal turn in airshow, and in mock combat. What do they have to lose, only a hundred millions USD aircraft and their life .Sure sound legit

    1- LM pilot didn't said his F-35 lost control, what he said is
    There are several phenomenal when you go to high angle of attack,first is the flow which normally very smooth and get over the surface, start to separate and get a lot of turbulent, so first we have the basic control ability problem -high angle of attack and flow separation, this is basic problem for all high AoA testing, if you think the flow doesn't start to separate from Rafale/Gripen air frame when they are at AoA of 100-110 degrees then you are simply delusional.
    2- High yaw rate does not represent higher level of control ability, the control ability is show in how fast you can start and stop the yaw rate as well as how accurate you can control it. 90 degrees/sec yaw rate is irrelevant if you need a more than 1 circle to start/stop it. Otherwise, follow your logic, Gripen got nothing on F-18 and F-18 which both can reach and recover from 100-120 degrees/second yaw rate respectively

    I said: Airflow departed the wing surface to an amount high enough to prevent the attitude to be called flight, that's what I meant by departed.

    As for Rafale pilots, they never said "can't stall it", which you recognised by pretending that there was only one maneuver which would allow for it, but "can't put it in a superstall", because the A-C is fully aerodynamically stall resistant and even if you could force it into one superstall, its control authorithy remains high enough to get out of it, you really should have a look at this U. Clarus report on the Gripen, it gives good clues as to why the close-coupled canard delta have such characteristics..

    The simplified definition of stall which mentions only AoA as a cause is incomplete, or else, speed wouldn't be such an important recovery factor, so speed matters just as much as AoA when it comes to loss of lift (regadless of the amount of airflow remaining on the wing surface), a "purist" or newbie will always see it as in AoA/low speed situation in level flight, obviously it is limited to one way to stall an A-C.

    In short, in an attitude where your AoA is zero but your speed too low to provide lift, as for the case of a renversement, you are already PS, so you can keep thinking 15kt provide enough of it to keep level flight on a 10t + fighter, I reiterate that it is not the case and that at this point you already are in a stall situation.

    Furthermore, it is much unlikely that the maneuver was done on the horizontal plan, I do not have the details of those mock combats but I can guaranty you that the pilot didn't try to slow down the A-C on the horizontal plan by putting the engine in idle, use A-F function, keep it level while increasing AoA and wait for the speed to crash, he most probably did it during a defensive or offensive yo-yo in the vertical plan, with full control authority for the speed (sluggish but still there) much closer to the renversement maneuver situation.

    So yes, you can stall a Rafale at 15kt.

    I suddenly came to ask myself a question, is the structural load factor of Rafale high enough to pass a renversement using rudder at a speed where it would still rotate the A-C 180* while vertical?

    Good question eh? Because there is no TVC or propeller torque to help pass the hammerhead maneuver on this jet, in theory it should be possible, depending on this Structural load factor...

    now a little question for you:

    I take my kid for a flight here and there, and he always asks me to do some "rollercoasters" (his name for that manoeuver), my plane is a DR400-120, so no aerobatics, heavy G, inverted flight and so on.. stall speed level is about 50kts. During the manoeuver, we get at moments down to 40, the ground somewhere way to one side and yet, the aircraft isn't stalled.. it isn't even close (and no stall warning horn, no buffet, nothing...)

    what type of manoeuver allows it? if you find, you may understand why the Rafale was never stalled @15kts and didn't need to be
    Really? So Picard, Sampaix, now another geezer, you guys keep on with this character bashing, it's funny, I don't need your expertise in aerodynamics to know that you perfectly can stall a Rafale, enough with forum legends, and I did read the full Flight test report when it was still available and not the truncated version of it among other documents on the A-C.

    Try a renversement, your kids will love it: Pull up vertical, wait for your anemometer to crash, when the AC give you a good buffet, Rechaufe Carbu (on your A-C), idle gas to kill your speed and when you feel the A-C is about to go down, full gas with rudder in the propeller rotation to help it yaw until you are nose down, then keep full throttle, off Rechauffe Carbu up to the speed which allows your A-C for recovery.
    Here you go, you just experienced a PSM.




    Did I mention Speed again?

    To summarize; It matters little how much of airflow remains on Rafale wing at 30* AoA and 15kt, part of it already departed the surface despite the very good low/speed high AoA airflow characteristics provided by the canard surfaces, as I said, it is not a Chinese Kite, (and at 10 tons +, no DR400-120 either) and the result is that you do not have enough lift left to stay airborne, stall is characterized by loss of lift to this point, AoA or speed or both.

    There are a few ways to stall an A-C, this is just one of them, sure it still had 3 axis control but the A-C was out of its flight parameters and the definition of flight means enough lift to stay up, nothing else, so at 15kt/30* AoA it was PSM.

    ps if you haven't practised the maneuver I described during your training, first do it with an instructor, or your kids wont enjoy the results that much.

    Say you, pretending that a Rafale cannot stall when in fact they need to stall it not only for spin tests but also landing (that's what it is, flare is a controlled stall) take some doing, do you really think the airflow is still there to provide enough lift at 30* AoA and 15kt?

    What makes you recover from a stall? SPEED. When you run out of speed, you simply don't have enough lift left and that's a stall.

    Chinese Kite stories.

    Good vacation then, but a bit of advise, stop posting stuff such as "can't stall a Rafale" instead of can't put it in a superstall because it is resistant to it, it doesn't serve French forumers credibility.

    Yes it does, for one thing I certainly don't ignore is the relationship between airflow speed and lift, no speed, no lift, simple enough, read the definition of a stall.

    Yes it does, for one thing I certainly don't ignore is the relationship between airflow speed and lift, no speed, no lift, simple enough, read the definition of a stall and 15kt is way to low for the airflow to stay on the wing surface, even with FCS limiting it to 30* AoA, (not 29* at the time but 30), you already departed, whatever the A-C attitude, you don't have enough of it to stay airborn.

    Another detail, they never said they couldn't stall it, they said they couldn't get it into a superstall, which is different, it is a characteristic of Delta Canards, the boring stuff gives you links to Gripen tests and those are explained in detail.

    The fact that they conducted spin trials is the proof of it, they needed to stall it first, passively (speed) or dynamically (AoA), passive stall is the equivalent of flaring during landing, if you do it 1000ft above the runway, it won't matter a bit, it still will stall.
    Feel free to elaborate instead of emulating the flamers, because this is the precise reason why the French community get bashed up, and coming up with inaccuracies such as this one doesn't help.

I can only advise not to feed the troll this only charges his troll batteries and motivates him to become even more aggressive. Hope there are still dome mods who will put an end to this, rather sooner than later. Otherwise we'll see another months long troll attack which will surpress any other discussions.

    as said don't feed the troll!!!
    O_0 oooch.

    Another acute paranoia sufferer, after Picard, now this guy, do you have any other to name, one of those who demonstratively demolished your "Rafale" and aerodynamic "expertise"?

    I visited an Indian forum once, aren't you the geezer who tried to pass himself for a German Air Force mechanic and pretended that E-F canards were used in the roll axis once?

    I know German engineering is supposed to be top but you got me hurting with laugher there.

    Have a good day sir.

    on the other hand, if their FCS is programmed to remain capped at 28-29, it's not supposed to get there in the first place, no? There was an interview of the Rafale chief test pilot Yves Kerherv who explained that, during development, for spin testing they had to disable a number of fcs features to have it in a pretty much "direct mode" (no automatic recovery of anything of the sorts) as the aircraft simply wouldn't depart into a spin regardless of what the pilot did, and what's more, even when they finally managed to get it into a spin, all they had to do was to release stick and rudder, and the aircraft would recover itself aerodynamically (with no input either from the pilot nor the fcs - as the fcs was in that "direct mode")
    So, basically, if they have made a choice not to go into post stall manoeuvering and programmed the FCS that way, how would you see the Rafale doing any post stall manoeuvers?
