Product face. Who will buy the fifth generation Russian fighter?

Guests are dear


They tried to make MAX-2019 as spectacular as possible: as much as possible in conditions of actual isolation, when you should not wait for crowds of foreign guests and overseas exhibits. Viewers, for example, were first shown experimental C-37 on a static site. The once-promising “deck”, existing in one flight instance and useful for testing the technology of the Su-57 fighter.




It was the latter that became the main hit of the air show: few could imagine that Russia would decide to show a fifth generation fighter to a wide circle of people on a static platform. On the plate proudly flaunted “Su-57е”, where the letter “e” denotes the export orientation of the machine. This, of course, is just a publicity stunt. De facto, they showed us not a new version of the aircraft, not a pre-production model, and not even one of the flying prototypes. “Su-57e” is nothing more than an integrated full-scale stand (KNS) for ground tests, which has existed for quite some time.

It is unreasonable to blame the organizers of the cabin: no country in the world will most likely put on display the latest inconspicuous fifth-generation fighter for everyone to see: if you want to see the F-35, Su-57 or J-20 - watch flight performances. The logic is simple. The real possibilities of a real export Su-57 will largely depend on the customer’s desire. It’s hard to say what exactly he wants.

In fairness, we note: now there are pretty high-quality photos of the latest flight prototypes of the Su-57 - T-50-10 aircraft (tail number 510) and T-50-11 (tail number 511). They give a good idea of ​​what will be a production aircraft, which, as we are promised, will be ready this year. Of course, with the so-called engine of the first stage, that is, AL-41F1. Which is nothing but a profound modernization of the Soviet AL-31F engine mounted on a Su-27 fighter.

The above facts are especially important when you consider that foreign customers will also receive just such a complete set: the new engine, the “Type 30”, will be ready in the second half of the 2020's. And maybe at the end of the next decade.

With current engines, the platform’s potential is not fully disclosed, but here one more important point needs to be taken into account: engines are certainly important, but stealth is much more important for a fifth-generation fighter. It is her experts who consider one of the main reasons for India’s refusal to participate in the project to create an export version of Su-57, formerly known as FGFA. Allegedly, the plane does not comply with stealth standards in the form in which it takes place on overseas vehicles. Judging by the photo, where the prototype of the engine compressor blades were clearly visible, this is most likely true. But you need to wait for the serial version of the machine, while it is too early to draw conclusions.



“E” means Erdogan


Now the main candidate for the purchase of Su-57 is Turkey, paradoxically as it sounds in connection with history with a downed Su-24 bomber. Turkish President Recep Tayyip Erdogan was able to consider a new aircraft during the Moscow air show.

“Is it Su-57? .. And is it already flying?” - Erdogan asked Vladimir Putin during the inspection of the exposition of the air show.

“Flies,” the Russian president said.

“Can you buy it?” Asked Erdogan.

“You can buy,” Putin answered with a smile.

"Why not? We haven’t come in vain. After we find out the final decision of the USA (according to F-35. - Approx. Aut.), We will take our own steps. The market where we can provide ourselves with what we need is large, ”the Turkish leader told reporters.

All this very eloquently shows the seriousness of intentions. However, one more thing can be understood from Erdogan’s answer: even after the Americans gave Turkey a turn from the goal regarding the purchase of the F-35, the Turks still do not want to abandon the project. So the fate of the Turkish Su-57 directly depends on the decisiveness of Uncle Sam, which is still unshakable.



Recall, back in 2018, the US Congress officially banned the supply of F-35 fighters to Turkey due to Ankara's purchase of Russian C-400 anti-aircraft missile systems. The latter are increasingly viewed as a formality, since so many political contradictions between the West and Turkey have accumulated over recent years that the problem of buying a C-400 simply fades against this background. Anti-aircraft missile systems - just an excuse to cool the ardor of Erdogan. In turn, the warming of relations between Turkey and the Russian Federation, as well as the need for Turkey to rearm its army, makes Erdogan the main potential buyer of the Su-57.

Su-57 vs J-20


Against the backdrop of the Russian-Turkish talks on the Su-57, other interesting information appeared. The Chinese state-owned publication Huanqiu Shibao recently wrote about the possibility of acquiring the Celestial Empire of Russian fighters, but only after a detailed comparison with the Chinese J-20. Experts from China noted that the Su-57 probably has superior thrust and maneuverability. “One video of a demonstration flight to any specialist in aviation it’s already clear that the Su-57 engines are superior in quality to the engines of our J-20 fighters. At the same time, the Russians say that these are also engines of the first stage (first stage. - Approx. Auth.). And there they are also preparing the second stage, ”the Chinese experts noted in the discussion of the demonstration performances of the Su-57 at MAKS-2019.

However, the thesis of a possible purchase by China of Su-57 seems far-fetched. The Chinese have already received the technology of new Russian engines in the face of AL-41F1C: together with a batch of 24 Su-35C fighters. AL-41F1C engines and AL-57F41 installed on the Su-1 are different products. However, neither one nor the other meets the requirements of the fifth generation, which means that China is hardly interested.

From the point of view of increasing the combat effectiveness of the Chinese Air Force, the issue is considered incorrect in principle. China is already mass-producing fifth-generation fighter J-20, and on the approach J-31, which experts consider the deck “invisibility” for promising Chinese aircraft carriers. China may be interested in issues related to stealth. However, it seems that the PRC itself does not doubt the superiority of the J-20 over the Russian fighter in this sense.



In general, Su-57 is facing difficult times that will show whether the machine is competitive in the global market. Now, developers will not be able to blame failures for "secrecy" or "the need to ensure the native Air Force."

The interest from foreign customers is a direct demonstration of the potential of a combat aircraft. If the machine really has outstanding capabilities, then there will always be a customer for it. If not, then no.

      Why so hard? Putin at 20 - he suggested Trump the Dagger to be sold (he himself said this at a recent forum, and the State Department confirmed the refusal), if they ask, then you can also put Su-57 directly wink .

      With wisdom, the equipment sold (not piece copies but lots) allows us to go further in the development and that means to get ahead of competitors.

    In general, everything is clear with Su57. There are no engines; a country that has risen from its knees with the help of Putin is not capable of engines crying
    Upgrading old Soviet engines is still possible, but new ones are gone.
    With stealth, too, is not so hot. It remains only "over-maneuverability", but it is unclear whether it is really needed.
    And what about Su with weapons and avionics? Is everything all right?

      "Super maneuverability" is one of the side properties of the aircraft, which he acquired due to its aerodynamic qualities and engine capabilities. And he can do what other fighters cannot do, even if they really, really try. And what's wrong with that?

Judging by the photo, where the prototype was clearly visible engine compressor blades ... 1. I hope you know that the engine compressor blades looking out of the air intake indicate a great radar visibility of the aircraft. And the blades are no longer made of titanium (VT-22 alloy). Do you know firsthand about composite materials? 2. Here is the beginning of the tests in a popular form for you: http://forum.militaryparitet.com/viewtopic.php?id=543&p=46 Compare. 3.

                And how can “hot” engines affect the EPR, which primarily depends on the specifics of the geometry of the airframe, its radar absorbing coating and measures to hide the air intakes?

                    Well, and what is the "specificity of geometry" sticking out the engines? Probably good?

                    A glider is a glider. Engines are engines.
                    Likbez: the stealth glider geometry consists in a low (flattened) silhouette and parallel lines located at a certain angle, providing minimal reflection of radio waves to the transmitter of the irradiator. Hence the triangular shapes at the wing, the reduced number of joints and the "gear" transitions. All these measures are used to minimize the reflection of radio waves from all angles, but not to the detriment of flight performance. Otherwise, we get an 117 iron.
                    For particularly tight: all these qualities are present on the Su-57 in full.
                    and how will you apply a radar absorbing coating on them?

                    Radar absorbing coating is not applied to the nozzle. They use a special form of “cloves”, which can be seen on the 30 Product. In addition, the sticking out non-stealth nozzle at the same F-35 for some reason does not bother you. Why? wink

                    This is the most common development in aerial combat. Su-57 was designed with all the scenarios in mind.

                    and what to do with the turbine blades?

                    These are not turbine blades, but radar blockers, I already wrote about this.
                    Quote: Beringovsky
                    and if the adversary comes in from the side?

                    The adversary will not go sideways, because it will be detected by lateral AFAR radars that Su-57 has, but not American planes. And if it does, then exactly the same thing will happen as if our plane enters the adversary from the side.

                    And don’t talk. They shine everywhere. On F-22 a little less, on the others a little more. If earlier this was relevant, today for missiles with modern infrared guidance heads, neither one nor the other is a problem. Therefore, today even the Americans did not make a key bet on this when developing a new fighter.

                        Umm, as they say, and cho? smile In fact, it is no secret that Sukhoi made a bet on reducing the visibility of the front hemisphere in order to maintain balance with flight qualities and based on the application doctrine. The mid-sectional area is identical with the amer and the EPR in the frontal projection is identical for them - this is the main thing and this is what the developers sought, consciously choosing the design of the airframe (and based on the features of avionics, but this is another story).
                        Yes, in Su-57, between two air intakes and engine nacelles, a space of about 1,5 m wide is a familiar design in the style of Sukhoi. And it forms a bearing surface with an area of ​​several square meters, due to which the lifting force increases. Hence, additional buns with flight capabilities at large angles of attack and angular velocity of a turn. And survivability is higher in case of failure of one of the engines. A belly deployed to the radar will shine many times more than any aircraft. Only this is not a key scenario for the development of events in the DVB, it is a situation from the BVB, when the EPR does not matter anymore and where the Americans will be crippled, and Su-57 not.

                        As I said, the aircraft industry is a complete compromise wink

                        F-22 will only decline over time

                        I do not quite agree. The raptor is being modernized and quite successfully, this is not a secret. F22 is an excellent samol. Of course there will be fewer, but is it critical? There are almost 200 pcs and in conjunction with Ф35 it is power. How many Su57 do we have there? Ah, not one ...
                        And your vaunted adversary as he sees the enemy, if he does not turn on his AFAR and does not start to glow like a Christmas tree?

                        1) from Ф22.
                        2) from Avax
                        3) from ground defense systems
                        4) with drones (possible)
                        5) using IF sensors. By the way, it is to them that the Americans are now paying special attention. As one journalist says - Coincidence? I don’t think so ...

                        I agree with this, but there are several BUT.
                        Firstly, this is an aircraft ahead of its time, yes, but it was 20 years ago. He gets upgrades, but mostly these are new “firmware” and program codes. That is, in terms of the same radar, for example, the F-22 has received almost nothing new since its release. And the “Squirrel” of 57, as well as its electronic warfare system KS101, is much more advanced and more functional today. Yes, it plays a role that they came out later, but nevertheless, we have what we have. Well, we don’t discuss tactical abilities and armament of airplanes. Still, Sukhar’s nomenclature of weapons is at times, literally at times more. F-22 will not be able to launch the same tactical missiles like our Gadfly and other special equipment, including ultra-long explosives. This must also be taken into account.
                        Secondly, F-22 almost 200 pieces, but in flight and combat readiness out of half. And I personally doubt that the number of combat readiness will increase.

                        Okay.
                        1) If F-22 turns on its radar, it exits masking mode.
                        2) We also have AWACS.
                        3) Comment will be below
                        4) Also below
                        5) And what is the range of work? The same Raptor does not have OLS on board, but it provides stable search and capture already at 50km, if not more. And taking into account the fact that according to official data, Raptor AFAR sees the target 1 m2 at a distance of 241 km, at what distance should it see the Su-57 in the "vacuum" frontal projection? There is also evidence from another example: the target detection range 0,1 m2 (typical cruise missile) for our station is 165 km, for the US about 115 km. The only data that is, what to believe and how - let everyone decide for himself. I still believe that in a spherical collision, both planes will see each other almost simultaneously. Excluding interference. And they will be and what then, one devil knows, the OLS comes into play.

                        About 3 and 4. The problem is that for some reason you are considering a theater of action on enemy territory. (Radar from air defense, drones ...). The reality is that our doctrine is built around defensive measures and we just rely primarily on the motive on our territory. Where we ourselves have a radar and AWACS and so on. Those drones will not survive there. And the AWAXS will be shot down first. But these are all spherical horses in a vacuum.

I’m not sure, of course, that the Su57 flew over Iraq, as if they weren’t getting there and that the Amer’s radars were there, but let's say they were standing and lit, maybe this is why doubts about the stealth of the latter come from all sides?

              The USSR tanks of the latest versions at that time were of only one interest in the composition of the armor of the tower, its front hemisphere, cheeks, filler, etc., and the VLD of the front hemisphere of the hull, the rest is all equally weak, from T-72A to T-73B3. I suppose then everything was already known, and there were other relations with the Americans. The T-80 lost due to the MSA, accuracy, shorter combat qualities.

    Engines are always much more complicated than an airplane and they are made longer than an airplane. In the USSR, engines have always lagged in all respects from American and Western. Let's do it, this is a very complex unit. The Chinese buying fighters from us can only copy the plane, but the engines cannot. Too sophisticated technology that we do not issue, but only sell off-the-shelf engines.

I hope you know that the engine compressor blades looking out of the air intake indicate a great radar visibility of the aircraft. And the blades are no longer made of titanium (VT-22 alloy). Do you know firsthand about composite materials?

      Just think, Boeing, Lockheed, the Chinese are struggling so that the blades are not visible, but everything is so simple - put the "radar blockers" and it's in the hat! Yes you are a genius sir hi (no lol )
      The engine compressor blades looking out of the air intake, that is, the absence of a “serpentine” (S-shaped air intakes), indicate a large radar visibility of the aircraft. In fourth-generation fighters, they try to hide the blades with deflectors, but such a decision can negatively affect the operation of the power plant.

        I repeat once again: these are not shoulder blades, but radar blockers. And to determine whether the EPR is high in an airplane today, only its developers can. Less accurately: other specialists who are trying to predict the EPR by studying the layouts and composition of RP coatings. You do not look like such a specialist how much.

          It seems to me, as a layman, that making an airframe with S-shaped air intakes is much more difficult than installing deflectors? Or not?
          So why did both the Americans and the Chinese choose this path? Deflectors would cram and deal with the end. But no negative

            The Chinese generally automatically copy everything they see laughing But seriously, these decisions are dictated by the structure of the airframe and the features of the mid-sectional area, the location of the engine nacelles and other similar factors. We could blow the air intakes in the same way, and move the engines on the contrary, especially since there is such an experience. But they didn’t. Everything rests on TK and needs.

    a new engine, the “30 Type”, will be ready in the second half of the 2020's. And maybe at the end of the next decade.
    With current engines, the platform’s potential is not fully disclosed, but here one more important point needs to be taken into account: engines are certainly important, but stealth is much more important for a fifth-generation fighter. It is her experts who consider one of the main reasons for India’s refusal to participate in the project to create an export version of Su-57, formerly known as FGFA. Allegedly, the plane does not comply with stealth standards in the form in which it takes place on overseas vehicles. Judging by the photo, where the prototype of the engine compressor blades were clearly visible, this is most likely true.

    Yeah. When two years ago I wrote that there were no engines and no stealth, which titles the local "patriotic public" did not award me. As it turned out, millions of flies can also be wrong.

              The facts are not related to faith or patriotism. Than inferior, traction and resource? Yes. On the contrary, nozzle rejection capabilities are an unattainable advantage. Its key role (bringing a fighter to supersonic speed without afterburner, ensuring super maneuverability, short take-off) has a different role than your vaunted F135. Let me remind you that the carrier is not capable of either stable “supersonic” without afterburner, or super maneuverability, but you didn’t notice it, right? And this shame is not interesting to you. And about the shoulder blades read above, I'm tired of repeating everything to everyone.

          About the shoulder blades have something to add?

          What do you know about shoulder blades, madame? Well, other than the subtle from the sofa-analytical resources? What do you generally know about the ability of materials to reflect, scatter and absorb the energy of an incident radio signal? What do you know about the properties of RPPs based on solutions of the system of scalar Maxwell equations for plane harmonic electromagnetic waves, based on the use of the recurrent procedure for calculating the characteristic matrix of a layered medium? You rush with radar blockers, not understanding its essence. And even more so, not realizing that now the Su57 is only in the form of test samples, that is, not combat, combatant vehicles. And you have already raised the fuss lol

    Why are the comments so negative? The plane "began" in the "fat zero" ... With the appropriate organization and "go wild" in terms of costs. The situation has changed. However, the plane was completed. Flies, and how. The topic of invisibility in Russia has always been advanced and studied deeply. Not to the detriment of aerodynamics.
    The engine of the new stage is doing with might and main. And it will be expensive to make it a small series.

    The Chinese have already received the technology of new Russian engines in the face of AL-41F1C: together with a batch of 24 Su-35C fighters. AL-41F1C engines and installed on the Su-57 AL-41F1

    The Chinese did not get the technology, but the turbojet itself ... earlier they received Al31 ... they also buy civilian Boeings and Airbases with modern turbojets. But all this does not mean that China received Al31 / 41 TECHNOLOGY. They sold Su30 technology, except for AL31 turbojet engines.

      With all this, I would like to commercialize the project .. this will allow you to release not 100-200 Su-57, but 500-1000. And all this is working hands and loading of production with high-tech products. For example, Su27 / 30 / 35 - the most massive heavy fighter.

      the Americans only decided on the requirements for the 6 generation, and then, apart from the optional piloting and huge altitude, it’s really not clear

        J-20 put in a series before us. J-31 on a hike (our analogue is still at the "one and a half engine" stage).

          And what is J-20? This is the layout we borrowed from the 1.44 MiG with modern stealth solutions. Engines are designed on the basis of our AL-31-F, which are already somewhat outdated. Because they buy engines from us. What is inside and how it works: is unknown. What about weapons: it’s not clear. What about avionics: not clear. In a word, a dark horse.

          There is even less information about J-31, except that it is also arranged in the image of F-35.

          The Chinese sought to become the second in the race for stealth fighters, creating such an abnormally short time. How this will affect its capabilities, quality and quantity of childhood diseases is a big question.

            All right said. Well, then what? They have a serial fighter of the 5 generation, one more will be soon. Yes, they torn something (but did not the PAK FA blame it?). Yes, the characteristics are classified (as if by SU-57 they are in the public domain). But this does not change the essence: today the Chinese are one of the leaders in this matter. I am not talking about who is better there: J-20 or SU-57. But talk about "what are these Chinese?" - stupid. Not Mexico any.

              so that’s the question, is it 5?

              Ok, rephrase the message. Anyone can have a nice sweetie if they have money. But China does not have many years of experience in fighter aviation, and in some key factors (engines) they are critically dependent on us. Their aircraft have not yet had time to establish themselves in any way. In addition, China is now actively scolding our weapons on all fronts in the light of increasing competition in exports. This is also important.

    May country into engines. The tests are on.

    Radar absorbing coating is not applied to the nozzle.

    what does the nozzle have to do with it? And here it is applied?

    So why is he not there?
    They use a special form of “cloves” that can be seen on the 30 Product

    so there is none yet crying
    In addition, the sticking out non-stealth nozzle at the same F-35 for some reason does not bother you. Why?

    let it confuse the pilots of the f35. But in case of which we will have to deal with F22, and there everything is in order with that.
    And don’t talk. They shine everywhere.

    Well, yes, only in different ways wink one light bulb per kilometer is visible, and the other, and from a hundred meters barely visible. Given the very strong superiority of amers in electronics in general and sensors in particular, this is of great importance. Whoever sees first has that advantage.
    The adversary will not go sideways, because it will be detected by lateral AFAR radars,

    turning on which will lose all "invisibility". Besides, at what distance can these frail auxiliary radars be able to spot an adversary?

    Given the strong superiority of amers in electronics and sensors, you can dislocate a Mosk, wondering why there are no OLSs on the F-22, why map mapping on the F-22 appeared 20 years after being adopted, why their radar systems have less power, but higher receiver noise, worse resolution and smaller scan angle.

    The turbine blades visible from the front only indicate that the turbine blades are visible in the optical range. But in the optical range in any aircraft a lot is visible.
    And if the blades are not visible - then they are not visible only in the optical range.
    And if you take, for example, a bent waveguide, you cannot see anything through it. However, the magnetron at the end of the waveguide perfectly sees through the horn at the other end of the waveguide the entire mirror of the reflector. :-)

    Nice plane. You will not say anything. According to insider information, the lineup of potential buyers has already been lined up for the purchase of the Su-57. While orders and quantity are considered, the final cost of the export option is determined. We will soon find out the first customer :)
