Features of a new generation anti-G suit for the Su-57 pilot

34

PAC with inflated pneumatic chambers



This year, the Russian Aerospace Forces are expected to enter service with fifth-generation Su-57 fighters. To begin with, it is worth recalling that according to the original plan, the start of operation of these fighters in the troops was scheduled for the end of December last year. But then, as you know, the plane crashed during the acceptance tests. And the design and production group began to refine it.

In NPP "Zvezda" they talked about the creation of a flight suit that belongs to a new generation of pilot equipment. Such a suit is planned for use by pilots of Su-57 fighters. Its features, as reported, are that it is more effective in helping the pilot to overcome the g-forces that occur in flight. In particular, the pneumatic rubber chambers of the PPK-7 anti-G suit compress the pilot's lower body and upper limbs. In this case, the compression ratio depends on the acceleration of the fighter and does not allow the outflow of blood. The suit's pneumatic chambers begin to inflate literally a split second before the start of the overload itself on the pilot.

An additional compensating effect is created precisely due to the larger area of ​​the compensating sections. The mass of the PKK-7 is no more than 3 kg (depending on the size).

In this regard, the question is being discussed why it was necessary for the Su-57 pilots to create a new anti-overload suit?

It is important to note here that even on the first versions of the Su-57, the fuselage design is such that it uses about 70 percent of composite materials of increased wear resistance. In particular, the designers used polymer carbon fiber, which made it possible to more than significantly reduce the total weight of the combat vehicle. As noted earlier, when creating the Su-57 from materials traditional for previous generations of fighters, its mass would be at least four times more than what is now in the existing configuration.

A significant reduction in weight naturally affects flight performance. The fifth-generation fighter Su-57 is capable of performing maneuvers that are even theoretically impossible on many other fighters. And this is where the conversation arises about the possibility of an increased load on the pilot during maneuvering (over-maneuvering) and how to overcome it. A sharp increase in load can, for obvious reasons, lead to serious consequences for the pilot. Hence the need to use a suit with higher capabilities to compensate for the arising loads in flight. A pilot, on whose body, a fraction of a second before the occurrence of an overload, pneumatic chambers begin to act (including exposure to the arms), has the opportunity not only to prepare, as they say, physically, but also to perform certain actions to solve a combat mission.



Includes Su-57 pilot equipment and a special protective helmet. This is the modernization of the ZSH-10, which is lighter than many analogues, as it is made using organoplastics. According to some reports, the upgraded helmet is interactive multimedia, which allows synchronization with the control devices on the panel. In conditions of increased loads associated with the functionality of the Su-57, the ability to have access to control even in the most difficult situations is extremely important for a military pilot.

This equipment will be improved as the pilots master the Su-57 fighter after it is put into service with the Russian Aerospace Forces.

    What was added to the limbs is good. But the vessels in the eyes will continue to burst, and the retina with the lens is in danger. Give Hunter quickly!

      Then the first serial Su-57 would have to wait, otherwise half a year has passed since the accident, and there is no new aircraft yet, it will not be possible to fulfill the contract at such a speed within the specified time frame, and this is 76 aircraft by 2028.

        It's even scary to say whether the SU-57 will be needed in 2028. Maybe they will quickly set up some kind of hypersonic ... but at least MANPADS and tady what we want.

          Of course it is needed, the Americans put the F-15 into production again, and the modernization of the F-35 is designed for 10 years.

    Does anyone know which ejection seat is on the Su-57 and what is the angle of the seat back?

      Does anyone know which ejection seat is on the Su-57 and what is the angle of the seat back?

      What are the main features of the ejection seat for the Su-57?

      We are following the path of modernization, so there is no revolution there, but, firstly, the anthropometric range is expanding, the weight of the product is reduced, the range of adjustments, the gunpowder, which are used in the ejection system, have a wide range of temperature applications. After all, we understand that the aircraft has an export potential, and we have been working on this topic for a long time.

      The automation that is used on the Su-57 chair is much smarter than on the systems that were used before. This means that the pilot's rescue is guaranteed in many more situations than before. Inverted flight, corkscrew, on the ground, and so on. By the way, the seat is also installed on the Su-35 planes that are supplied to the troops.

      The main feature of the product, as Sergei Pozdnyakov, the head of the Zvezda Research and Production Enterprise, said, is its perfect "brains", that is, automation, which at all heights and speeds allows the rescue of the pilot.

      At the same time, the seat will not have the function of "shooting" in automatic mode, Interfax reports.

      In 2017, the head of the Tekhnodinamika holding, Igor Nasenkov, told the Zvezda TV channel that the new catapult seat for the Su-57 would be able to independently decide on the ejection of the pilot.

            - In the very first big exercises with the participation of the F-22 in Alaska, Northern Edge, regular exercises. Here is an article for 2007 (the F-22 has been in service for two years then), where this is mentioned:
            https://www.flightglobal.com/export-ready-the-f-22/74029.article
            In all subsequent exercises, its combat effectiveness was only confirmed and confirmed. For 15 years now ... smile

              There is only one thing!
              Nowhere did long-range aerial combat in practice show such efficiency even close.

                In the same way, before the drop of nuclear bombs on Hiroshima and Nagasaki, it was never possible to kill more than one hundred thousand people with one bomb ...

                Technology advances ...

    Cho really?
    "As noted earlier, when creating the Su-57 from materials traditional for previous generations of fighters, its mass would have turned out to be at least four times more than what is now in the existing configuration."
    From the wiki:
    Su 57.
    Length: 19,4 m
    Wingspan: 14 m
    Weight: empty: 18 kg
    normal takeoff weight: 26 kg maximum 510 kg
    Fuel weight: 11 100 kg
    Su 35.
    Length: 21,9 m
    Wingspan: 14,75 m
    Weight: empty: 19 kg
    normal takeoff weight 25 300 kg maximum 34 500 kg
    fuel weight: 11 500 kg

    IMHO, someone wants to enlighten everyone in full.

    Hardly with very close TX values, the plane could be awesome light, awesome maneuverable, awesome ....... Either stealth or awesome aerodynamics ...

    They would write in the normal way: "maximum operational overload: + 10-11 g, but before it was +9"!
    Therefore, the new suit and valve ...
    Instead of mud.
    What does wear resistance have to do with it?
    Confused with specific strength?

      It looks like the authors were carried away, they misled, the closest thing: "compared to the Su-27, the Su-57 glider has four times less details", from here: http://www.airwar.ru/enc/fighter/su57.html
      The article is completely nonsense.
