Of course. And there are always ways to neutralize those additional seekers too, like concealing, aerosols and purpose-built flare / chaff dispensers capable of hiding a whole military column in IR and RF. Everything is relative to the technological and proficiency levels of the involved armed forces. What is a cake walk against a weak opponent turns exponentially more difficult against one with more resources.
flares, chaff, and aerosol will block sensors from both sides.
but yep there are always ECM and ECCMfor everything
Not really, a big warhead or bomb will rain heavily with shrapnel everything in tens of meters. A radar or light vehicle would be still destroyed.
If you lose accuracy, you have to increase the size of the warhead, this is only logical.
That is somewhat irrelevance as ECM when they work can easily generate miss distance on order of hundred meters
A supersonic missile with big range and big warhead will be both much more difficult to shoot down and much more lethal than a small bomb hitting farther from target than it is intended to
IMHO, it depends, supersonic missiles aren’t always harder to shot down, they often have a higher signature, hence easier to detect and harder to mask with ECM, and you can always carry more small missiles than big missiles. Individually, 1 AARGM-ER might be harder to shot down than 1 SPEAR, but does 1AARGM-ER harder to shot down than 4 SPEAR ?

“Electronic warfare specialists from Russia’s Central Military District tested a new method of jamming enemy aircraft while using three different types of ground-based electronic counter-measures systems, the District’s press office reported on Monday.
“During the experiment at the Sverdlovsk and Chebarkul practice ranges, servicemen used the Borisoglebsk [electronic counter-measures] system to conduct radio-electronic reconnaissance. By penetrating the channels of communications systems’ control, they created interference in the operation of ground and airborne radio communications employed by a notional enemy,” the statement says.
Russia’s cutting-edge weaponry capable of ‘blinding’ enemy’s arm The teams of the Krasukha [electronic counter-measures] system suppressed the signal of an onboard radar installed on an aircraft and also the radio channels of controlling unmanned aerial vehicles. The activation of the Zhitel hardware made it possible to shut out satellite communications equipment, navigation and cellular communications systems within a radius of 30 km,” the statement reads.
The new method allows electronic warfare specialists to create “vacuum” space shielded from the impacts of drones, airborne radars, radio-controlled high-explosive munitions and cruise missiles, the District’s press office explained.
The drills involved about 500 servicemen, the District’s press office specified for TASS.“The experiment involved unmanned aerial vehicles, communications systems, dummy munitions and aircraft,” the press office said.”
Scenario
Lets all say there is an assigned mission to take out 3 pantsir systems but these systems are within the area of the 3 mentioned above EW systems. Aircrafts are deprived from targeting these mobile pantsir systems and cruise missiles are deprived from getting information from the aircrafts radars and satellite information to find where these pantsir systems are.
However the problem is this
Some of these systems are not mobile when set up. This means that SEAD can still effectively be conducted as long as aircrafts launch missiles at a far enough range. https://www.oxts.com/what-is-inertial-navigation-guide/
Switch on a GPS receiver and, assuming everything works correctly, after a short time it will generate a position measurement. Ignoring the inaccuracies GPS has, the position measurement the receiver generates is quite specific. It says ‘
you are at this latitude and this longitude
‘—in other words it gives us an absolute position using a known co-ordinate system. Inertial navigation systems don’t work like that. In their case the measurement they generate is relative to their last known position. So even after an inertial navigation system has been turned on for several minutes, it can’t say ‘
you are at this latitude and this longitude
‘, but what it can say is, ‘
you haven’t moved from where you started
‘.
I am assuming that a computer with a laid out map program on a missile shows where the planned targets are, Sensors say how far the missile has travelled from its last known location to the computer, the computer gets updated with the distance travelled from the sensors and determines when it will hit the planned targets.
So the only issue I am assuming with INS is its computer needs the program before the mission starts of where the 3 desired targets are. However these 3 targets are mobile. Data can be transmitted to update the program on the computer of the missile but EW systems deprive that from happening. But the EW systems are not mobile systems like the pantsirs which means they can still be targeted with the before mission program on the computer of the missiles. Which means although the pantsirs are mobile systems but to not be targeted they are to protect these EW systems from INS guided missiles.
The other countermeasure against EW systems and SAM units are EO devices but this can be targetted soon enough by peresvet which I am assuming is going to be like a land based sokol echelon.
Pantsir systems effectiveness has to be good enough to cover EW systems.
EW systems have to be good enough to provide an increased survival chance to SAM units from being hit by making aerial targets left in the dark long enough.
Good enough Military coordination between EW and SAM units is needed for increased effectiveness.
Although there is no way to determine how effective these systems are against a SEAD attack from aircrafts as in poor or high performance. Is this analysis of mine correct, is there things that I have missied?
What stop anti radar missiles and UAV from attacking these EW station?
Well, it depends on the weapon. For instance SDB (GBU-39) or JDAM lack additional autonomous guidance methods and would essentially fail or have their accuracy strongly affected in case the GPS signal is degraded. Other weapons have radar altimeters or MMW seekers that can be affected by EW too. And every step taken to make the weapon capable of being used amidst strong and sophisticated EW employment makes it also notably more expensive and either short ranged or less powerful. That is a reason why some of us think many of the currently used PGMs are not really usable against peer rivals with their military capabilities intact since they would fall short in terms of accuracy, range, speed and destructive power, and rather intended as low cost solutions for military engagements against weak opponents. It is also a reason in favour of bigger warheads (with a significantly bigger destructive blast and therefore lethal radius) instead of “micro” weapons like SDBs, since they can be both more effective in case of degraded guidance (not only EW but also masking etc are to be considered) and also compensate for the cost of the more expensive seekers installed on them. Given the weapons mentioned above are among the most widely used in the West, EW alone would put a significant additional cost and tactical burden on those militaries by forcing them to substitute cheap and simple weapons that can be used in great numbers to saturate AD with much more expensive ones with multi-mode seekers that would besides have reduced range and destructive power performances. This puts the current model of widespread use of small PGM against all kind of military targets under question, since not every target would be worth the investment and salvo size needed to make the weapons effective. And the needed increase of weapons size would favour carriers of increased capacity vs. “light” strike platforms like F-35
There are many ways to overcome EW
Current GPS guided weapons have anti jam
SDB II has additional IIR and SAL
AARGM-ER, SPEAR-EW have passive RF
LRASM has additional IIR, passive RF
Multimode seekers are still available on small weapons such as SDB II and JAGM
Besides, I think big warhead is not a relevance or effective way to overcome electronic countermeasure unless you put a nuclear warhead on missiles.
Big weapons will have bigger radar, visual, infrared signature. Thus, both hard kill and soft kill countermeasures can be applied toward them sooner, they are also harder to mask with support jamming
Simply put, F-35 – or a targeting pod with basic ISR capabilities- has nothing such as a sophisticated and dedicated 1.5T reccepod can give (be it focal, number of sensors etc.). “basi isr” is also known as NT (non traditional) ISR.
A dedicated recon pod will have bigger aperture than F-35’s EOTS and DAS, and possibly in wider spectrum as well. On the otherhand, F-35 can get much closer to the threat bubble than a Rafale or Gripen carrying 1.5 tons pod, so while its optical sensor might not see as far as a dedicated pod, it can get closer to see.
Furthermore, i don’t think F-35 recon mode is limited with optical sensor, it is likely that APG-81 and ASQ-239 are used as well

Most Russian “trrick”, the wonderful things Flankers and Su-57 we are use to see now are POST-STALL manoeuvre where, yeah, the loss of energy is high.
AoA even at the extreme angles displayed by the F-35 are within the flight domain of the aircraft where wings still provide lift and the nose is simply angled with its velocitu vector, allowing rapid recovery
Respectfully I disagree, F-35 post stall such as pedal turn also consume a significant amount of speed and altitude.
…….Bla bla bla …….
get over it, it proved useless and that’s why it wasn’t necessary to trick Gripen and Rafale FCS for this sort of stunts, or why top gunners flying F-22 don’t use them, good for fanboyz at airshow or flaming in forums, not so in combat.It’s not my trolling you got dragged in, it’s your inability to distinguish between your wet dreams and reality, something you two have in common, I really can’t help you with that.
Sure , engineers at Lockheed Martin, Boeing, Sukhoi, Chengdu, Hindustan will be very interested in your expert knowledge to help them understand post stall maneuvers are proved useless, clearly they still can’t distinguish between wet dreams and reality
Then what do you think vortex breakdown means other than “flow which normally very smooth start to get separated
1- In High AoA testing, they are looking at angle from 20 degrees and greater
2- One common characteristic observed, as AoA increased, flow start ti be separated ( there is no indication when at what AoA that happen)
Your logic train is like when you heard the doctor say: “people lose blood when their skin is cut” and “when a person lose too much blood, he die” then you interpret that as “when a person has a small cut on his skin, he die”
Keep on trolling. I am done with you.
Don’t say I haven’t warned you guys. It’s the ever same picture since 15 years or so that this guy is trolling aviation forums across the internet. Sampaix, Fonk, Thunder, Dare2 and whatever nickbames he has used, one must be blind not to recognise that distinguishable pattern of the “go back to school”, “learn the basics”, “use proper aviation teminology”, “you don’t comprehend” etc. phrases like a shouter on his local bazar. It’s all too familiar as is his whining about French and Rafale bashing and pretending to be the poor victim who is shot for being the messanger of “universal truth”. Ofcourse he will pretend not be himself, that’s the reason why he precisely knows what people like me are talking about with reference to his past appearences here and elsewhere and that’s the reason why he knows about specific subjects discussed that certainly only people involved can know.why? Because no one else cares and that’s why I tell you to put him on your ignore list and let him starve out of the attention that he desperately needs. I know this will be ignored and the BS will go on until some moderator will finally lock down the thread and hopefully bans the troll as had been the case countless times in the past.
You got a point. I was dragged in his trolling
Are you finished making a fool of yourself publicly?
Did you figure out the difference between controlled flight and out of control departure yet? What does maneuver means? Because all the funny examples you gave us, F-4/F-14, F-111, F-16, all with pretty much well known unpopular stall characteristics demonstrated either one of the other of those two things:
You still can’t figure out the difference between controlled DEPARTURE and a combat post stall maneuver.
I am not the one who try to blur a spin departure test and PSM

2) You have no clue what you write
Ironic coming from someone who was proven wrong again then again
Personally, I think both, and something else, in the F-35 video, the flight engineers says himself that they start encountering vortex breakdown at 20* AoA, which would explain how a Gripen can reach a yaw rate 30*/sec higher in the same yaw spin with the advantage of having full controllability from the start of the maneuver, since they don’t speed stall it and lose control as the L-M team explained, but stall it dynamically (you got the concept or you’re going to post tons of unrelated pictures you haven’t comprehended yet again?).
Now, vortex breakdown, loss of lift, buffet, aerodynamic bashing are well known and advertised characteristics shared between F-18, F-22 and F-35, with the F-22 perhaps the least affected by it because as I already stated, it is a DELTA wing, but there is a good reason for this to happen, let’s see, LEX plus inlet strakes equals two more sources of vortex.
Getting quite desperate now do you, i love how you try to merge
Taurean comment: “for high angle of attack testing, we actually looking at angle higher than 20 degrees….”
and
Dan Canin comment: ” as angle of attack increased, the flow which normally very smooth start to get separated ..”
then interpret that as “the flight engineers say himself that they start encountering vortex breakdown at 20* AoA”, distinguishing liar
best example, posting about F-18 LEX forgetting Rafale is equipped with them too, but has the advantage of more interaction between other vortex sources to keep the airflow steady at higher AoA
In the world of Thincankiller where all wing shapes are equal, all rudders design are equal and all LERX are equal regardless of their shape and size.
I reiterate. Gripen departure in yaw spin was a full scaled PSM becaused the A-C was put into it by stalling dynamically, even at low speed, demonstrating pitch control at those low speed, with increased AoA up to 70/80*, controled in both acceleration/deceleration and stop to the yaw rotation before full recovery with full 3 axis controly ahthority throughout the entire length of the maneuver.
Yep, you keep saying that but SAAB themselves never claimed Gripen can use post stall maneuver in combat and of course they also programmed the aircraft to recover when the AoA excess 26 degrees
Gripen 90*/sec, F-35 60*/sec.
Which is irrelevant since it is a spin recovery test and not a post stall maneuver, F-16, F-18 has all been to higher spin rate and recover. You don’t even know many spin it need to get to 90 degrees/sec, let alone how many spin it need to stop.
No LEX on a F4 did you say?
There is no LERX on F-4, yes, that is correct. So compare an ancient aircraft with positive stability such as F-4 with a close coupled canard fighter then declare that it is exactly the same between a modern with fighter with lerx and negative stability is quite disingenuous
how come F-18/22/35 all experience vortex breakdwon at lower AoA than a close-coupled canard then?
interaction between wing and canard vortex can strengthen them, delay break down.
But then again, depending on speed.
How many sources of vortexes do you think there are on F-35, Gripen and Rafale? You can extend that to F-18 and F-22 if you wish.
LERX, canard, in some case inlet chine and nose cone
WHY does L-M even bother with Vortex generators such as LEX and Strakes?
What deos the vortexes have as effect on the F-18/22 and F-35 again?
The vortex flow creates an area of high negative pressure on the wing upper surface which increases lift and delays separation of laminar flow

What is the reason for aerodynamic bashing of fins and elevators for those A-Cs?
vortex break => unstable turbulent
During the tests, when in the AoA scale did L-M start noticing vortex breakdown again?

try to impress someone else with copy/paste material you don’t understand, then just answer the simple questions I asked in my previous reply, no need for a calculator, and btw, since your pal got spanked in the F-16 forum, he havent learned anything, still come back with the same false arguments, wrong examples (F-4, F-14, F-16 and so on, all the worst in the book)… Hilarious.
Wasn’t this document posted to him at the time?
A wind-tunnel study to find the lift and drag characteristics of a low-aspect-ratio wing/body configuration from an angle of attack (AOA) of -8 to 50 degrees was conducted.
A further study to find the comparative lift enhancement using the same wing/body with a close-coupled canard for wing/body angles of attack of 10, 22, 34, 40, and 48 degrees and canard deflection angles from -25 to 25 degrees was carried out.
It was found that a properly located canard enhanced the lift at all tested angles of attack, compared to the baseline wing/body configuration results.
The lift enhancement was maximized in the post-stall regimes, reaching values up to 34%.
A small improvement in lift-to-drag ratio was noted at all tested angles above 10 degrees angle of attack.
Compare to F-35 test pilot explaining how at high AoA (not P.S yet) they already experienced vortex breakdown, buffet and loss of control and you got the scoop, better tough, trying to pass aquaplaning for controlled powerslide on a car forum, I can imagine the face of some drivers there…
Which is quite disingenuous in your part, given that they were comparing a close-coupled canard design with a pure wing design of the same kind, no LERX, Chines whatsoever. LERX too can improve lift at high angle of attack.

Frankly, as i said, ther more you copy/paste the more it is obvious that trying to emulate and copycat someone is not your forte, you haven’t figured that those who knows their basics can spot those who doesn’t only this way and it’s is EA.SY.[/SIZE][/FONT][/COLOR][/LEFT]
I am sure that you don’t know your basics, given how you interpret the relation between G-limit and sustained G.
The only thing you know is vortex this, vortex that, canard . That it , then you try to project that on every single things , all the wise ignore all related factors. You are like a guy who happen to know sweep wing has delayed mach cone than straight wing, and therefore he concluded that no aircraft with lesser sweep angle can fly faster than an aircraft with more sweep wing.
It’s not “claims”, boy, it’s BASICS aerodynamics you never bothered to learn.
Yep, your so called “basic aerodynamic knowledge” when you think fighter sustained G is greater then 9G at Mach 0.8, 15k ft or spin departure equal combat post stall maneuver, i am sure never bothered to learn that kind of baSiC AerOdYnaMic
I can comprehend what is actually written simply because I have learned the basics and much of the more advanced stuff, not to mention had it demonstrated as a student in flying schools, thus I can easily tell who knows what and it becomes clear to me that the most basic stuff already eludes you big time. I do, I can’t help it if you chose to keep yourself in this dark zone of ignorance of those flight mechanics principles, and this is no “claims”, this is aerodynamics and physics.
If you really learned much more advanced aerodynamic stuff than any of us, i am sure you can solve this aerodynamic math problems easy:
Prove to us you aren’t just an armchair expert then.

110* AoA isn’t exceptional for a modern fighter and completely unnecessary to reach for spin tests since your most efficient angle for those tests will be in theory closer to 90*
whatever your pet fighter has done must be the most efficient, every other way is complete trash. I understand your thought
Now you haven’t managed to shown me “to be wrong and have to change my claims over and over”, since I keep repeating the same thing again and again
Let have a quick recall shall we
1- you claimed no US fighter had been tested anywhere close to 100 degrees AoA=> turn out F-35 had been tested to 110 deg, same for F-22 , even F-14, F-15, F-16 all had been push to 90-100 degrees AoA in their test, this say a lot about your knowledge of spin departure test
2-you claimed that F-35 rivets will all fly out long before the pilot pull 10G=> turn out ,it had been flown to 9.9G
3-you claimed operational G load is directly proportional to ultimate structure limit, sustained or instantaneous aren’t important => turn out, it clearly isn’t , i showed you and example that F-16 with higher ultimate structure limit can have lower sustained G limit than F-15 and also the fact that fighter can’t sustain anywhere near 9G when they fly at 10.000 feet or higher. As a bonus, i showed you that pulling higher G doesn’t neccesary translate to a higher turn rate unless both turn are performed at the same velocity, but you choose to ignore that.
4-you claimed F-16 pilot just let go off the stick and the aircraft will recover => turn out he recover from the spin by rudder input
5-you claimed F-35 KPP specs change is the evident that its structure get weakened => turn out you were hilariously wrong, the Sustain G spec at that altitude is no where even near 9G
6- You claimed Gripen test is a post stall manuever test while F-16 test was a spin departure test=> turn out, they are both spin recovery test, it is even mentioned in the test report how the anti spin logic and the recovery control law of Gripen operate, there is not even a single word in the test report mentioning that the spin departure can be used in combat.
7- You brag about how Gripen spin rate can reach – recover from 60 degrees/seconds spin rate in its spin departure-recovery test => turn out, it is quite usual thing, F-16 spin rate even reach 120 degrees/second in spin departure test.
8-You claimed that F-35 can’t perform any post stall maneuver and it was only tested for spin departure recovery=> turn out, not only i can post multiple video of F-35 perform post stall maneuver in a fully controlled manner, but also the comment of pilots talking about how he used the pedal turn in dogfight exercise and then the test report of Lockheed Martin clearly stated that F-35 can perform post stall maneuver in combat like its brother F-22
9- You claimed Gripen has extremely good high AoA nose control that why its FCS does not limit the aircraft to 26 AoA like F-16 => turn out, the flight control test report also show Gripen recover system will automatically engage after AoA of 26 deg
10-You claimed that Post stall maneuver is useless, and all other airforces limit their fighters AoA to maximum of 30 degrees => turn out you are missing out on F-18E/F, F-35A/B/C, Su-30 MKK, Su-30MKI, Su-35S, Mig-35, F-22, Su-57, FGFA
it still is 30*/sec slower in the yaw axis Post Stall than Gripen and this is rather relevant when it comes to the so-called PSM designed to face a threat, it demonstrates two things, you don’t need TVC and a close-coupled canard can maneuver more efficiently than a conventional design PSM? Gripen 90*/sec yaw rotation rate, F-35 60*/sec. Enuff said.
Again, you try to blur the line between Post stall maneuver and a spin departure test
FYI, F-16, f-18 reached and recover from 100-120*/sec yaw rotation rate in these kinds of test.
So much for “undocumented B.S”, it’s been up since the mid-80s and studied from the 60s.
B. CLOSE-COUPLED CANARD
The advantages of a close-coupled canard have been known since the 1960s.It was found by Behrbohm [Ref . 1] that the combination of a close-coupled canard and delta wing, of small aspect ratios, has significant advantages over a conventional delta-wing or wing/horizontal-tail configured aircraft.
Both CLmax and the angle of attack for CLmax are increased by the addition of a delta-canard to a delta-wing.
NAVAL POSTGRADUATE SCHOOL Monterey, Califormna
THESIS……….-
FLO WFIELD STUDY OF A CLOSE-COUPLED CANARD CONFIGURATION by John F. O’Leary
As expected from a disingenuous person, you skip out the vital part of that study
The comparison was against positive stable conventional wing-tail aircraft. Not to mention that F-4 also lack vortex generation device such as LERX or chines.
So, exactly like i said, you cherry pick a small part of information to make your case, while ignoring all relevant parameter that influences the result.

You’re so full of it you still can’t read plain English. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZ…
NOPE. 110% was the maximum AoA, the aircraft departed FAR earlier than that, but since you still can’t comprehend the meaning of the words you copy/paste, we still have to suffer B.S by the bucket.
Yes, with a tweak in FCS and intentional control, F-35 can be put into a spin before 110deg, so what?.
I love how you keep claim that i don’t understand the words while it is you who was shown to be wrong and have to change your claims over and over.
Stop writing in Aviation forums, take on knitting
Well i am not the one who made up idiotic claims then get shut down by test report and flight manual pages.
No secret here, it matters little which AoA you are at low speed to achieve this if: a) structural integrity of the airframe allows b) depending on your particular A-C aerodynamics, your yaw axis will be controlled by either one set of control surfaces or another, (adverse, induced etc).
On Close-coupled canards (or ANY canard surfaces equipped A-C), there is no use of the canard surfaces in the roll axis for reasons of structural torsion (it would require a much too heavy front fuselage), on the other hand, as demonstrated on Mirage IIIS/NG/4000 and IAI Kfirs (close-coupled), the airflow on the fuselage, boundary layer at the A-C wing roots and around the vertical surface is enhanced/energized by the presence of vortexes from nose cone strakes/LEX/Delta wing root, canard root and on the Rafale, the design of the fuselage itself.
So you have several sets of vortexes to keep the boundary layer on the airframe in this area, meaning vortexes breakdown occurs at much higher AoA.
That’s a particular characteristic of the design which seems to elude to many people writing about it, at high AoA, the boundary later sticks to this part of the fuselage when that of conventional designs have already vacated, not the case of Close-coupled canards, no need to consult in forum but to read studies about the formula from people who knows, like NASA/DRYDEN/Dassault/SAAB, interpretation if forum is much too often tainted and inaccurate.
and people in the know such as the one work at SAAB don’t claim PSM for Gripen, neither does Dassault themselves ever claimed Rafale capable of performing pedal turn or Kulbit or Herbst, enough said.
The only thing you actually know is close coupled canard keep vortex from break down later than a pure delta, but that it, you have no numerical data to compare the side force that a close coupled canard such as Gripen can generate at high AoA such as 50 degrees to compare to twin tail aircraft such as F-35 or F-22 at the same exact condition. You have no data to evaluate how accurate their control can be or how fast the yaw can be initiated or stop
In other words, your “analyze” base on very small amount of generic information all the while making very big claim and ignore dozens other related factors, it is like someone who say higher sweep wing has less drag, therefore, Mirage III must fly faster than Mig-25.
There is NO “effet boîte à meuh” there, NO aerodynamic limitation if this is what this B.S means to some, quite the opposite, if you mistake acceleration with roll rate, as explained hundred of time by people who served in A-F using them, limitations are there to allow for your average squadron pilot to keep the A-C under control at all speed, since there is no speed limiter for example, and btw, the Mirage 2000 is also limited this way, even more in G than a Rafale
btw, on F-18/F-35. vortexes breakdown in the area is also well documented (fluter/structural issues caused by aerodynamic bashing), so whatever AoA they will reach, they will not be as efficient as that of a close-coupled canard, even with the use of 2 vertical fins.So you guys can keep the effet boîte à meuh for confetis to throw at weddings because it’s what it’s worse, bar if you want to keep flaming French posters in forums.
Another claim with no data to back up.
FYI, posting that photo of F-35 in the wind tunnel with vortex hitting its tail (like you always do in other forums) doesn’t prove your point, because:
a- You don’t have the same tunnel data for either Gripen or Rafale
b- You don’t have such data at all AoA, there is no chart or overlap curve showing their relative controllability at all AoA, it is nothing more than speculation in your part.
c- F-18/F-35 can perform post stall maneuvers, and had demonstrated such ability, none ever seen from Gripen or Rafale.
You don’t need 30/40/50* AoA to do a pedal turn, all you need is low speed, at whatever AoA your A-C will allow you to pass the maneuver, so if you have the choice between transcient performances (energy/acceleration) and AoA which will take it all away from you, and become more of a limiting factor than an advantage, limiting the A-C AoA makes perfect sense.
Conclusions of PSM tests were the same than those reached by X-31 pilots with on top the comment made by Yves Kerherve; “we don’t need TVC”.
.Their comment was never that post stall maneuver is useless, but rather that it is not worth it to trade of important characteristic, such as acceleration or speed just to get PSM, that mean for example: it is not worth it to have post stall maneuver if in the process you decrease acceleration by 20% due to the added weight from TVC. On the other hand, having post stall maneuver capability while not having to trade other fighter characteristic or the loss is small, it is really worth it, since it can very useful in certain case and for that reason, many new aircraft still designed to have post stall capability such as Su-57, Su-35, F-35, F-18, F-22

Actually, bar going over 29/30* AoA, yes they can, because you don’t need to get into a stall to do a pedal turn, you can do it in a stall though
If it is such an easy task, why you still unable to find any video of either Rafale or Gripen perform the pedal turn?
And even more efficiently, as demonstrated by Gripen maximum yaw rate in yaw spin tests, 30*/sec is a huge difference when it comes to 60* to 90*, but there is little advantage in ACM there
High yaw rate in departure test offer no advantage to operational ACM, because in controlled departure, aircraft don’t have the same level of control to get a fire solution like in a combat post stall maneuver. Beside, max yaw rate accumulated after several spins can’t be used in combat either
Take this a step further and this is precisely how you depart an A-C asymmetrically (as demonstrated by the descriptive of the yaw spin test on Gripen), start a yaw spin and stop it, you’ll also need to recover speed, meaning using pitch, and all of this at AoA much lower than that reached by F-18/35.
F-35 departure test was done at 110 deg AoA, i am quite Gripen don’t go much further than that.
close-coupled canards allows for lower AoA for the same amount of vortex lift (appears earlier in the AoA scale), therefore, higher lift/drag coefficient.
Compare to a pure delta, yes.
Other kinds of wing? not necessary, after all, delta is a kind of very high sweep wing.

ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZ.
Bucked of commercial B.S for fanboyz revisited.
Answers are simple, already gave them but fanboyz can’t read properly, they only can interpret, and YES F-16 is even more AoA limited than Rafale or Gripen, other than that, it is plain obvious they they won’t pass those airshow stunts in combat because it makes them slow, energy-less targets, they didn’t with F-22, they won’t do it with F-35 which is inferior to it PS.
Repeat all you wish what you chose to believe, FACT is, Gripen passed a PSM with a yaw rate 30* higher than F-35, NOT at 50* AoA but between 70* and 80* AoS, meaning NOT High AioA but well past departure AoA.
They also stalled the A=C dynamically, meaning they started the maneuver with FULL control of it throughout and stopped it, when L-M test pilots speaks of loss of control, should; be clear enough but you’re unable to comprehend what it means.
And i’m done arguning with you since you obviously don’t comprehend what is written in the first place (high AoA vs Post Stall for a starter), as I first said, their stunt is advertised as high AoA, even the air show one, and the goal of those tests were high AoA, never to test PSM and validate them for combat, even if S-H does it, it doesn’t make them so hot in ACM, this bit obviously is the commercial B-S-ing that get the crowd behind the manufacturer, unfortunately, they overdone it, some of us knows what spin tests implies even if you don’t.
End of your wet dream methink.
Laughable for a troll such as you to call test report commercial BS but theory that himself come up with as fact.
Even funnier when you pretend like every single countries i mentioned earlier only use F-16, do you think that people won’t noitice when you skip out: F-18 E/F, F-35, F-22, Su-27, Su-30MKI, Su-30MKK, FGFA, Su-35, Su-57? I have never said PSM is some sort of super silver bullet in close combat, nor did i ever claimed it is the strongest point of F-35. But PSM can be useful in some conditions that why many countries still keep it
To honest though, it is sad how you keep making claims that you can’t back up then have to keep changing your claims over and over until you lose any credibility you ever got, like how you have to keep changing your claim from ” f-35 has never beeen tested anywhere close to 90 degree AoA” then to ” F-35 was only tested in spin recovery ” then to ” F-35 can’t perform PSM, because it lose control at high AoA,” then now to “F-35 PSM is inferior to F-22 so it will never be used in combat “. That desperation is both hilarious and sad at the same time.
FACT:
according to SAAB, they tested Gripen in an intentional departure test to verifed high AoA limit and spin recovery control system. There was never been a single word from SAAB themselves or Gripen pilot claiming Gripen can use post stall maneuver to gain advantage in combat (clearly opposite of what LM and F-35 pilot talk about F-35).
Just because Gripen was put to higher yaw rate then recover, doesn’t indicate more accurate control than f-35, after all, F-16 can recover from 120deg/sec yaw rate and F-18 can recover from 100deg/sec yaw rate. You now gonna claim “but ..but ..but Gripen get to that yaw rate by its arelions input”. It doesn’t matter because higher yaw rate can just be accumulated, as long as the side drag isn’t too high, the rate will keep increasing, you don’t know how many spin does it take to get to 90 deg/second, you don’t know in how many second gripen can stop if the pilot wanted to. In other words, that number impress no one but you.
