Rostec has created a stealth glass with improved performance

47



Specialists from the state corporation "Rostec" said that they have finalized the method of manufacturing stealth glass. Now the cockpit canopy of the "stealth aircraft" will receive improved characteristics that directly affect the combat potential and survivability of the winged vehicle.

The development belongs to engineers from ONPP "Technology" named after. A.G. Romashina (part of Rostec). It is reported that the new technology will reduce the radar visibility of the aviation complex and at the same time improve the optical characteristics, which just affect the survival rate, as well as the combat potential of the “stealth aircraft”.

According to Vladimir Artyakov, Deputy General Director of Rostec State Corporation, the first samples of stealth glass made on modernized equipment fully confirmed the design parameters.

As for the technology itself, it consists in using the thinnest films of metals and metal oxides deposited on the glass surface by magnetron sputtering in a vacuum installation. The latter, after refinement, makes it possible to deposit films with a significantly lower surface resistance due to an increase in the peak value of magnetron sputtering by more than 3 times. At least that's what the experts said.

Based on the data obtained during measurements and testing, the new stealth glass manufacturing technology makes it possible to improve the performance of aircraft cockpit glazing in terms of stealth by 20%.

    It's good that our military technology does not stand still. Look what useful breakthroughs in hypersound and missile weapons are helping us now. All the same, I am glad that, apparently, the "brain drain" has stopped and our scientific and technological revolutions are being implemented in products and products.

          Once they told the technology, it means they patented it, not classified it
          And that means the Chinese will get it too.

              That's the gist of it.
              It's like enriching uranium. There were only two countries with nuclear weapons, and then it got into the media that uranium was enriched in centrifuges. It seems that they did not reveal special secrets, but many were able to reproduce this technology by typing.

                  Yes, and Israel is in question
                  And the Iranian bomb - the Israeli intelligence agencies are too effective.
                  And Israel would not have demanded with such maniacal persistence to unleash a full-fledged war against it, if it had not known that Iran had the technology - many people want to wipe Israel off the face of the Earth, but Israel's number 1 enemy is Iran.

              These are just technologies of "coated optics" or glass (including organic). Known for a long time , used to coat optical lenses for binoculars , spyglasses , telescopes and ... spectacle lenses . Many who wear eyeglasses with more or less decent lenses are familiar with these coatings, they give a "metallic" residual reflection on the lens, while being more transparent and scratch resistant. Look at your glasses, if the lenses are polymer and coated, you will see a residual reflection of green, blue (purple), gold or even (yes) burgundy red (there are some). I have a greenish reflex on some glasses, these are German "Rodenstock" lenses. On others, the reflex is violet-blue, these are the French "Esilor". The coating is usually multi-layered, the better the materials and the more perfect the technical process, the more resistant the coating. And yes - it reflects EMP, as it should be with a metallized coating. That is why the lantern does not let EMP through and the internal elements of the cabin, reflecting the electromagnetic wave, do not unmask the aircraft as it would be without it. In most countries of the world, all cabins have long been covered with such a coating. And for some, even the material / coating of the cabin is photochromic - it darkens in the sun and brightens in the shade. Probably noticed? The plane takes off in the bright sun, and its cockpit is dark, like tinted, and it also gives a green glow (or gold) ... and lands when the cloud covers the sun - the lantern is transparent.

              It's just that in the Russian Federation they have apparently learned how to make high-quality coatings. And this is good .

            And the Chinese are already, still on the J-20. And they have a non-binding lantern.
            A similar glass was on the commemorative F-117.

              And what are its advantages over the design that we have?
              The fact that the junction can give additional illumination on the radar is not at all a fact (the binding can be made of composites, which does not give illumination, etc.).

              On the F-22, there is no binding on the lantern, but the later F-35 already has it again -
              lost technology? Or is he still needed for some reason?

                Exactly. On the Su-57, the binding is clearly not composite, as evidenced by the rivets.
                At worst, make the sawtooth edges of the lantern, like the F-117.
                Similarly, with the doors of the weapon compartments.
                lost technology?

                Look at the design of the F-35 lantern: glass whole, the internal composite arc is used only to strengthen it and as part of the ejection system through flashlight (which is not reset).
                Everything has been studied smile :
                https://forum.militaryparitet.com/viewtopic.php?id=16960

                Let me remind you that a one-piece teardrop-shaped lantern was used on the F-16.
                Whereas there was no such solution on any Soviet / Russian aircraft.
                The Chinese, however, were able to repeat.
                Of the undoubted advantages - a great review in close combat. It is strange that they did not try to implement a similar solution on a super-maneuverable fighter, visibility on the Su-57 became even slightly worse than on the Su-35:

                    Can't say for sure, but:
                    according to the chief designer A. Davidenko, by weight, composite materials make up 25% of the weight of an empty aircraft, and 70% by surface area.

                    The parts highlighted in yellow in your diagram clearly do not make up 70% of the airframe area.
                    And what hinders the review?

                    Compare with Su-35:

                    For comparison, F-35

                    And I didn’t compare it with the F-35 (by the way, it has a 360 'view from external cameras), it was about super-maneuverable fighters with OVT: Su-35, F-22.

                One more thing: the Su-57 has a glass lantern, so you can’t do without binding. Perhaps the reason for this choice is the lack of a number of technologies.
                On F-22, F-35, J-20 - polycarbonate, polyacryl, the last two are reinforced from the inside with carbon-fiber (radio-transparent) arcs.
                Let me remind you that the flashlight must withstand a collision with a bird at a speed of about 800 km / h.

                  About forty years ago, NITS specialists developed the technology of deep bending, when several layers of glass are placed in a special furnace and for several hours at high temperature under its own weight it bends, acquiring the desired shape and curvature. If necessary, special mechanisms push the workpiece, forcing it to bend according to a special schedule.
                  By this technology on the MiG-29 fighter, the canopy, which previously consisted of three glasses, was replaced with one non-binding silicate glass.
                  https://aviation21.ru/3246-2/
                  That is, we could make unbinding lanterns from silicate 40 years ago.

                  In terms of durability, he's okay. An example of a Tu-204 (I don't think the requirements are lower on a military aircraft):
                  "... With the thickness of the glass in the Tu-204 aircraft - 17 mm, and in the Boeing 787 - 45 mm, the passenger Tupolev can withstand a bird impact speed of 660 km / h, and the Dreamliner - 648 km / h .... "
                  ".... A few years ago, in order to prove the high strength of silicate glass, glass nails were made at the institute. They were hammered. They could be used in products with antimagnetic properties. These nails were also tested instead of clamps when gluing yacht hulls. But the nails remained only exotic ...." The link is the same.

                    He's okay with strength.

                    I talked about the fact that they could not make a solid silicate (“glass”) lamp of sufficient strength (moreover, it is variable, it is the front part that must withstand a collision), so I had to make it out of two parts.

      There are always a lot of Kulibins in Russia. But nanochubais with its nano-cutting of the mega-nano budget in Nanoskolkovo did not allow the creative potential of engineers and designers to be realized. We need a government program to support innovation, we need venture funds. Stalin coped with this task, including with the help of sharashkas. Grabin in 1941 designed and launched an artillery gun into serial production in 38 days. And now? In 2006, I designed a video recorder for a car in a garage, when there was not a single imported one on the market. Well, what's the point?

            You are very arrogant, no one became an academician in a charade, even Tupolev and Korolev became academicians only after they were released from there. This, in my opinion, is terrible, to work under the supervision of the NKVD shnikov.
            There is such a bike (I do not guarantee reliability): in the Tupolevskaya sharazhka they remade the Douglas into the Li-2, they are discussing an auxiliary engine that runs on an electricity generator. Tupolev is speaking, like I don't like this two-stroke engine, let's remake it into a four-stroke. And then the head of the NKVD shnikov decided to show who was in charge there: "How can we immediately remake it into a four-stroke, no, we will remake it into a three-stroke!"

These tasks include work on a diesel aircraft engine. At that time, reports appeared that the company "Packard" carried out a lot of research and practical work on the production of an aircraft diesel engine. Negotiations were underway through Amtorg to purchase this engine. Packard agreed to provide us with technical assistance, but demanded a huge sum for it (almost a million dollars). I was I was instructed to get all the material on this case. Through the work carried out, I acquired not only all the drawings, but also all operational maps for parts and recipes for steel for only a few thousand dollars. The material brought by me was handed over to a commission composed of Charomsky (now Hero of the Socialist Labor) and others to determine its value. The Commission recognized that it is of great value to us."

    It's good news that our designers and engineers have created such amazing glass. Now it's up to mass production.

      The main thing is that the equipment for its production is our production. And then we have trouble with this

        The problem of the modern world is that not a single developed country has all the sophisticated equipment and components of its own production.

      I remembered. Somehow our new owner comes, points to the receiver, and asks:
      - And what is it?
      - Alcohol mashine.
      After these words, I was stripped of my brigadiership. sad

        hi Vladimir, be proud!
        as explained by the expert
        It’s much dumber with foreigners, in short: the beginning of the 2000s, location - Western Siberia, subbase, my warehouse > Indonesian engineer Schlumberger Yandu is sad near Toyota for an hour - knocked down 2 puppies, your obedient servant with a slight hangover - Yandu, in a similar situation the Russians flatten the tire and say God, it's not me, the technique failed. After 5-10 min. sitting in the office I hear the rattling of an autopump, h / o 20 min. there is no car. yes

          Bullshit .... An American is working, his feet are on the table ... A guard comes to him, laughs himself, says a bomb was slipped under the American. The American grabs his daddy and runs. And finally, he asked: "Why are you laughing then?"

    Instead of "stealth glass", it would be better to finally create a non-binding lantern. He has been on the F-22 for a long time, even the Chinese on the J-20 (2nd photo) were able to, what's the matter?
