Rostec has developed new materials for glazing aircraft

32

Russia has created new materials for use in glazing aviation technicians. The developed materials have high strength and thermal stability, the press service of the Rostec state corporation reports.


Innovative materials based on polymethyl methacrylate (PMMA) have been developed as part of the federal target program. They have increased resistance to surface cracking and thermal stability. According to the developers, the properties of the new materials make it possible to use them on supersonic combat aircraft, as well as in civilian aircraft. In addition, new materials can be used in the space industry, shipbuilding, and railway transport.

New glass in its technical and operational characteristics correspond to the best world standards. (...) Some brands of new glass have already passed industry certification and received approval for use in the aviation industry, they are ready for industrial production

- said the Executive Director of Rostec Oleg Yevtushenko.

According to Vadim Lukonin, Director General of JSC Research Institute of Polymers, mass production will be deployed on the basis of this research institute, and knowledge-based small-tonnage production of necessary materials has already been organized.

(...) Glasses are ready for industrial production and can be used both in glazing the latest supersonic fighters Su-35, Su-30, Su-34, MiG-29 and other promising aircraft, and for the windows of passenger liners such as Sukhoi Superjet and MS-21

- he explained.

The development of new materials was conducted by the RT-Chemcomposite holding, which is part of Rostec.

    It would be nice to equip commuter trains with such glasses. It was at one time in the suburbs, some not very intellectually gifted - they threw stones at the glass of electric trains when it was on the move ...

      Plastic-based glasses have been tried for a long time, but compared with mineral glass, they have one significant drawback: low surface hardness and, as a result, even with the usual attempt to wrinkle such glass, it quickly dims due to the abundance of micro-scratches, ordinary dust always contains in the form of microscopic particles sand.

        Gorilla Glass is making progress in this direction, proved by personal experience. Xiaomi Redmi Note 7, the glass personally scratched with a sharp knife, though with very light pressure. There is a video on the internet where they do it with good effort. hi

          Glass can be hard, but brittle. They fight hard.

            So triplex is also made of fragile glass, where strength is achieved by multi-layer. request

              For a fighter flashlight, it’s nice to make glass with elements that reduce EPR.

              The plastic is covered with layers of mineral glass and serves to ensure that the glass does not crumble upon impact

      Ooh! In 97, he himself experienced this ... On the Odintsovo-Moscow train .... For half an hour he shook out the glass fragments from his jacket ...
      The most unpleasant thing happened a year later. The father-in-law and the mother-in-law also stayed in the country. The district policeman dragged our youngest "for the kingpin" - he threw stones into the train ...
      I am not a supporter of domestic violence and never beat my sons .... Besides, times! "Lieutenant, turn away or go away" The district policeman considered it best to "turn away" ... Then he pulled the officer's belt out of his jeans, and ......
      Despite the heart-rending protests of his wife and mother-in-law! Only father-in-law looked with approval ....
      Tom has already passed many years .... The youngest has become not only a highly qualified programmer but also a FATHER. And a very good father! He is generally a very good person and good!
      But until now - as soon as I touch the waist belt (to pull up my pants), the reaction is instant: "So, dad - stop! Not that! ...." I remember! Although this story was his ONLY serious childhood misconduct!

      There is a whole bunch of "problems". As written, especially with the sealant there were big problems. I don't know if they were solved.

          In general, MiGs 25/31 in terms of heat resistance were probably made at that time almost at the limit of the possible. The same SR-71 is titanium, which certainly simplifies a lot.

            But makes the glider wildly expensive.

              Before the hijacking of the MiG-25 Belenko, the Americans could not even imagine that such a "rocket" was made "only" of steel

        There was also news about the appearance of cracks in the glass of the cabin, even the Su-35. Apparently, this is a common problem for our aircraft. So now you can forget about her.

      According to the MiG-31 glazing, like a year ago there was information that they found new glazing compositions that allowed to increase the maximum speed ....

    can be used in the glazing of the latest supersonic fighters Su-35, Su-30, Su-34, MiG-29 and other promising aircraft,

    For the Mig 31 it’s probably still not enough heat-resistant and durable or they forgot to include it in the list, and without binding glass it wouldn’t hurt him to improve the view from the cab.

      Yellowed Plexus? Later, they suffered from this in the Second World War, didn’t they really solve the problem?
