Photos from the workshop show the underdevelopment of the Su-57 - the largest Chinese media

The Russian Su-57 fighter has excellent maneuverability and a spacious weapons compartment, embodying the advantages of two combat aircraft at once - the Su-27 and the American F-22. But images from the combat vehicle assembly workshop illustrate technological underdevelopment of the Su-57. Experts of the largest Chinese publication Sina argue about the shortcomings of the new Russian fighter.

The Su-57 is intended to replace the Su-27 in the future, the main targets of the Russian fighter are the US stealth fighters F-22 and F-35. Analyzing the images of the Su-57, the Chinese emphasize the strength of the aircraft, embodied in the XNUMX% frame structure of the aircraft.

Another feature of the Russian fighter is the division of the frame into two parts united by fasteners: a black extreme horizontal frame and a yellow frame. At the same time, the frame parts are made of titanium and aluminum alloy - the latter was used to create the outer and inner skin of the air intake, which is almost entirely based on the traditional design of third-generation fighters.

The use of a soft aluminum alloy as a material for cladding the air intake, as well as the use of rivets, demonstrates a gap in a whole generation between products of the Russian Federation, on the one hand, and the United States, on the other, in the development and manufacture of technologically advanced air intakes.

In modern aircraft, rivets are not used in the design of air intakes, as they can fall out and damage the engine blades. The solution to the problem was the use of carbon fiber and making the inner walls smooth, as well as the absence of rivets. Such an advanced air intake can only be performed using composite materials, the production technology of which is possessed by the USA, Japan, a number of European countries and many Chinese companies.

Seeing that the United States, Japan, and China can design and build advanced air intakes, the Russians can only openly envy without being able to do anything.

- Sina experts note, speaking about the backwardness of Russians in the field of research and development of innovative materials.

    The Chinese will not miss the opportunity to promote themselves, although it is precisely China's backwardness in research and development of innovative materials that prevents the Chinese from creating their own engine. For Russia, which, using composite materials, makes a wing for the MS-21 and a whole hull for minesweepers of Project 12700, if necessary, it will not be difficult to make small air intakes.

    This is a price / performance issue. If there is no gain, then technologies of previous generations can be used.

    The Chinese would be better off keeping quiet, the fact that they consider their fighters to be 5th generation aircraft does not mean that they really are and that they are recognized as such by other leading aviation powers, the Chinese have never shown confirmation of their claims in practice , and unfounded unsubstantiated statements to the case, as they say, cannot be sewn, in confirmation of this - the complete absence of an engine with the necessary reliability and performance characteristics, as well as the absolute unwillingness of the Chinese aircraft industry to provide such an engine in the near future !!!

    In December 2019, in a publication on the Chinese portal Sohu, the Russian Su-57 was declared a 4 +++ generation fighter (3 +++ in the Chinese version). It also said that "the Russians need to work harder so that they are not left behind by other countries of the world."
    Thus, the Celestial Empire reacted to the crash of the Su-57 that was to become the first Russian production model of a fifth-generation fighter that happened in the same month.

      When conducting actual flight tests, in which equipment is subjected to extreme loads close to critical, emergency situations are not excluded and are quite probable, but it is better to identify and eliminate all weak points in the process of experimental development and testing than during operation in the troops, they were and the Americans, when testing their F-22s, and even more so F-35s, the Chinese do not carry out such tests in full, their fighters almost did not participate in real hostilities, and in case of any failures in testing new types of aircraft, the Chinese prefer to hide This is all the information and to classify all the facts of such failures, the Americans have already reported several times about emergency situations with Chinese aircraft that occurred during the tests, this was recorded from American reconnaissance satellites, but the Chinese prefer to keep silent about such incidents !!!

        It's not even about "non-standard situations", but about the fact that the accident of one SU-57 led to a halving of their total number that entered the RF Armed Forces for TESTING (not even into service yet!).
        And in the same USA there are already more than 5 fighters of the 800th generation adopted for service.

          This is all understandable, but in the USA the serial assembly of the F-35 has long been put on stream, and international cooperation in the production of subassemblies and components also ultimately speeds up and facilitates the assembly of a large number of F-35 aircraft, and in our country, all production is concentrated exclusively in our country, and the only way to increase the number of produced Su-57 is the construction of additional assembly lines at KNAZ, or additional organization of assembly at other aircraft plants.

              Problems with the plane are justified by the notorious "financial issue".
              The question is: How can this be combined with the fact that the fortune of the 22 richest Russians has exceeded the size of the country's budget?

          And, by the way, most likely, there will be NO MORE!
          Since the US Congress decided to discontinue production of the f-35, in view of the obvious numerous shortcomings and the inconsistency of the aircraft being produced to the declared goals. Oh how! Captains are obvious! One must think that it dawned on them that the "penguins", if they can fly, then, "low, low, call us trochs"

          Uneven (VADIM STOLBOV) Recently, in one magazine, American analysts told interesting information that out of (though they called the number 600 aircraft) only 150 aircraft are in combat readiness. This figure is very different from the figure that you announced.

    Unfortunately, you have to face the truth. We are lagging behind. Initially, the MiG-29 was planned with carbon fiber air intakes. But, I could not stand the loads. Plus, the well-known problem of the MiG-29 keels, where corrosion occurred at the joints of carbon fiber and aluminum. So there is a problem. And it lasts for a very long time.

      There is a problem, but it is gradually being solved, now about 40% of the main units of the Su-57 fuselage are made of carbon fiber reinforced plastics.

      Dear, something have distracted you, I think - what does the problem of the MiG-29 have to do with the Su-57? If you noticed, he has a radically different airframe design, which has nothing to do with the MiG-29 airframe, from the word "absolutely"! Or do you think that Russia does not own composite technologies? Maybe then remind you about the "black wing" MC-21? And by the way, the MiG-29 "keel problem" you mentioned concerned only aircraft that were "mothballed" in storage. It was then that I served in the 14th Guards IAP, and the work to overcome this "trouble" touched me very much. And the representatives of 123 arz themselves, who carried out improvements on this topic, argued that the whole trouble was in the erroneous concept of preserving the airframe, as a result of which moisture accumulated inside the box-shaped structures of the keels, leading to corrosion.

    I looked for how the Chinese performed, but did not find it. The US and NATO refuse to participate in the tank biathlon, but call their tanks "super duper".

    In modern aircraft, rivets are not used in the design of the air intakes, as they can fall out and damage the engine blades.

    Yes, it all sounds beautiful when it comes to a purely civilian plane.

    The use of composites allows you to reduce the number of parts in a part, which means that the part is always more complex in configuration and larger in size, which means it is much more expensive than several metal ones, and the use of a composite material pays off only during long-term operation. Replacing such a part is still very expensive and time consuming.

    Here we are talking about a military aircraft, which, due to its operational characteristics, can quite often receive various mechanical damage. The weak point of polymer composites is impact strength. After impact, microcracks are formed in parts made of composite material, which, under cyclic loads, lead to material delamination.
    Such a detail must be changed immediately. In the worst case (for example, in a war) - after each sortie. What has to do with this, most likely, will have to be far from comfortable factory conditions, but on the spot, with the help of our own "crazy hands".

    The Chinese are not even aware of the fact that a Chinese bear cub will sit in the cockpit of this aircraft and sing Russian songs to knock American planes off course. The Americans will think that they are over China, although in fact it is already the Moon, and there will not be enough fuel back and they will crash on some mountains on Mars.

    The Chinese air intakes are cast iron, so no one has seen them in the manufacturing process.
