Accident Su-57 precisely during acceptance tests has its own plus


The crash of the new Su-57 fighter in the Khabarovsk Territory leaves more and more questions about the use of a fifth-generation aircraft in real combat operations. Indeed, if not for the accident, then many of the shortcomings of the Su-57 would have remained unsolved.


The fall of the Su-57 in the Far East during the acceptance tests played a very important role in the fate of the fighter. On the one hand, it was a serious blow to the export of Russian aircraft. The very same China immediately doubted in the sense of acquiring a combat vehicle, other potential buyers also thought about it. But at the same time, this incident made it possible to draw attention to those moments which, in the conditions of air hostilities, can become fatal.

Moreover, it is necessary to take care, first of all, of the interests of the Russian Aerospace Forces: they are the main buyer of the PAK FA aircraft. Currently Russian aviation takes part in hostilities in Syria. And if the Su-57 aircraft, having collided with the aircraft of a probable enemy in the sky, could not show the declared super maneuverability, this would have an extremely negative effect on the entire air operation as a whole.

Among the main problems inherent in the new machine, experts single out, firstly, the use of new control systems. At the same time, experts believe that the control system installed on the Su-57 is one of the most advanced in modern aviation. But it needs to be mastered.

Speaking about the engine of the aircraft, the honored military pilot of Russia Vladimir Popov at one time noted that the Su-57 is characterized by an unstable control system, which makes it possible to achieve high maneuverability of an aircraft. But its stability and controllability are very much dependent on the new engine, since the power plant and aerodynamic components are tied to each other.

The second possible problem is the tail. On the Su-57 it is represented by all-turning trapezoidal stabilizers, includes keels with small air intakes that allow cooling aircraft equipment. Keel deviation is used as an aerodynamic brake.

In addition to these problems that could lead to a car crash, the Su-57 has other obvious disadvantages. For example, many experts talk about problems with electronics, which is primarily due to the lack of domestic high-tech industries in Russia in this area.

Also, the aircraft has certain problems with stealth, which allows some experts to doubt the Su-57’s belonging to fifth-generation fighters. The lack of stealth for modern fighters is a significant minus, which greatly complicates the most combat use of the machine against a serious enemy, which has its own good aviation and developed air defense systems.

In any case, the fact of the plane crash will force manufacturers to double-check the control systems and engines of the combat vehicle. This is the main plus of the incident. And this is not an attempt at any excuse. Although certain financial losses will follow for the manufacturing company, but an extra recheck of the aircraft will make it possible to protect the lives of our pilots, and increase the reputation of the domestic military aircraft industry in the world fighter market. It is better to notice and eliminate the shortcomings on time - before the aircraft enters the troops, even if an accident occurs, than to “miss” them and then face a whole series of negative consequences.

    The delivery of the latest Su-57 fighters will be carried out according to plan, even despite the collapse of one of the aircraft, Deputy Prime Minister Yuri Borisov confirmed in an interview with Interfax. At the moment, the Ministry of Defense has signed 2 contracts for the supply of Su-57. The first has 15 aircraft, the second - 76 aircraft.

      But some "experts" on the blue eye have no doubt in the fifth generation of the FU-35, in the absence of supersonic speed without afterburner!

        Well this is the FU-35 and it is ordered to praise. And criticize all Russian. This fukalka is the same as the Patriot, which does not see anything and does not react to anything - Saudi Arabia is an example of this. Well, something, not a single Western “show” of air defense did not detect the flight of the Su-57 to Syria, flights there and the return flight. This is the real western fu-woo ...

    And on the way, Hunter ... it's hard for us to get this car. But the era of 4th generation fighter aircraft is approaching sunset, although they are modernizing these machines. But the concept of using fighter aircraft is more and more inclined towards multi-purpose use, therefore, the SU-57 is needed, which at the design stage was already conceived as a multi-purpose platform.

      And why is the Su-57 better than the fourth-generation Su-35?
      Israel does not even think of abandoning the heavy F-15, the F-35A will be a replacement for the F-16, just like in the USA. Moreover, the Americans are going to buy the F-15EX.
      I don't think the 4th generation era is leaving. Most likely the 5th generation will not be fully disclosed. But the 6th (unmanned) will be successful, IMHO of course

    In general, if not for the accident, the military acceptance aircraft would not be recognized as appropriate for the 5th generation. MO would refuse to accept, given the cost.
    HOW MUCH "responsible uncles" flew from posts? And then the accident, all (?) Errors are correctable.

    Also, the aircraft has certain problems with stealth, which allows some experts to doubt the Su-57’s belonging to fifth-generation fighters.
    This wanders from the "expert" to the "expert" - what is the magnitude of the EPR? Do not know (or only from the words of a competing company?) Then maybe it is not worth indicating what is not known.
    About the same Chinese, we do not know anything other than what they themselves say - "wah! What a car!" and perceive this for some reason as truth. although they even have junk engines.

      The problem is not far-fetched. The testers, especially those of the older ones, at first used obscene controls, cursed like hell. Then, however, they recognized these innovations as convenient and successful.
      And the accident, IMHO, is not a consequence of design flaws, but a factory jamb on a specific instance. Pre and New Year's hype.

      Yes.
      The native motor is reportedly to rise in 2024 or so. Generally, nonsense of course. The engine began to be designed literally a little later than the aircraft itself, that is, 2005-2006, and after 20 years it will get on the car. Speed ​​is creepy.
      Plus, someone mentioned earlier that the new engine was not particularly high-torque current AL-41F1. I wonder if he will catch up with the engine on the F-22

    What nonsense have I just read?

    After all, if not for the accident, then many of the shortcomings of the Su-57 would have remained unsolved.

    Since when does the car have many shortcomings and what do they have to do with this accident?

    The same China immediately doubted in terms of acquiring a combat vehicle, other potential buyers also thought about it.

    There were no official statements from China, just as there were no new “conceived” from other countries.

    And if the Su-57 aircraft ... could not show the declared super maneuverability ...

    And here is over-maneuverability in the list of “problems”, and even with the “if” agenda?

    The second possible problem is the tail.

    As mentioned above, where did the firewood come from? What is the problem, what is it manifesting in?

    many experts talk about problems with electronics, which is due, first of all, to the lack of domestic high-tech industries in Russia in this area.

    Who are many experts? And how are problems with the electronics?

    Also, the aircraft has certain problems with stealth.

    EPR facts and results where?

    Not a single paragraph is delusional or unfounded. Author, do not write more about the Su-57. Never.

    Speaking about the engine of the aircraft, the honored military pilot of Russia Vladimir Popov once noted that the Su-57 is characterized by a system unsustainable management, which allows you to achieve high maneuverability of the aircraft.

    For such aircraft, an aerodynamic scheme with longitudinal static instability is used. And "unsustainable management" happens only in emergency aircraft. The difference is fundamental.

    I am far from aviation. Highly. But I always have a question for “experts” who, based only on photographs from “authorized angles,” and I have met such situations, although not an “expert,” judge the characteristics of the technique. A photo is not an indicator, but a picture. So squeals about "Su-57 - not the 5th generation, not stealth, not ..." I think nonsense smile
    First, explain what the 5th generation is, where it comes from and how, otherwise it turns out that according to the screeches of the “experts,” the fu-35 super-fifth-generation self-propelled fighter does not meet the requirements that they proclaimed. I can only judge by what I saw in 2011. on the MAX - the Su-57 fluttered easily and gracefully even against the background of the Su-27. F-15, the plane is excellent, in my opinion, against the background of the Su-27, it looked like an invalid, suffering from obesity, barely performing maneuvers, and compared to the Su-57, it’s just a wreck for which it is a feat to get off the ground. This is about maneuverability. By "stealth" I will not say anything, I forgot to drag a couple of complexes. For acceleration-braking, the F-15 accelerates like a walk-behind tractor in comparison with a sports motorcycle, and brakes like a muzzle in cotton wool. Su-27, and even more so Su-57, is simply much more preferable here.

      I am also far from aviation, but a hunch tells me that in a modern war in the air, the one who will be the first to detect the enemy and launch the rocket will win in the air. I mean that maneuverability is important, but not as important as it was during the Second World War and beyond.

        In part, I agree with you. But for some reason, I immediately recall the F-104 and F-4 created on this concept. The first was immediately nicknamed "widow-maker", since it could fly only in a straight line, and the second, "phantom 2" which turned out to be a good fighter-bomber. But as a fighter - trash

    As the saying goes, when a car will shoot down enemies above our sky, it’s not important 4,5 or 100500 this generation.
    God grant that brought to mind. It’s probably really good that such an incident happened. Of course it would be better if they found a joint on the ground, but what is, that is. The pilot is alive and thanks for that.
    The question of sanitation: I have never seen a Su 57 make such crazy elements as a Su 35. Is it due to the fact that flights take place on prototypes, due to the lack of engines of the second stage, or is the 35th lighter and more maneuverable car? Maybe afraid? Although it seems that the tests were loaded to the limit and even higher.
