Nanostekla from Obninsk

Aircraft, spacecraft, and even icebreakers can not do without the unique glass Obninsk NPP "technology."

Russian technologies allow you to make the glass virtually invisible to the human eye. Developments of this kind have become the pride of a company Rostekhnadzor — Obninsk SPE "Technology".

 

The starting point for the development of glass production in Obninsk be considered in 1959, when the construction of the pilot plant — branch of Research Institute of Technical Glass. Later, for the development and production of non-metallic materials were created NPP "Technology", which is already more than three decades of developing high technology of products composite.

However, the most unique first development in this direction has appeared before. In the 20-ies of XX century Obninsk craftsmen from high strength glass sarcophagus created a body of Lenin, who protected him from bullets and explosions.

Today glass SPE "Technology" are mainly used in the aerospace industry. But this is not the only area of their application. For example, the logging icebreakers also set bulletproof glass from Obninsk, that provides a reliable protection against all types of firearms. And if the glass for spacecraft and icebreakers — still single orders, the production of "light" (as is traditionally called glazing cabins of airplanes and helicopters) delivered here, they say, to the stream.

Externally, these glasses look like normal, but in fact they are quite complex from a technological point of view the product. Coating them — a multi-layered structure consisting of very thin coating of gold and indium-tin-oxide. The thickness of each layer does not exceed 20 nm, This is tens of thousands of times thinner than a human hair. Their development was spent several years. It would seem, why, what can change this little thing? But scientists from Obninsk know that almost invisible to the eye thin film on the surface of the glass dramatically changes its properties. For example:

Radar stealth (technology "Stealth")
Transparent nano-coatings make aircraft less radiozametnym, in particular, do not give the enemy air defense systems, signal reflected from the cockpit and cockpit equipment is invisible to enemy electronic systems.Pilot protection from radiation, including solar, at high altitudes
Minimizing the effects of electromagnetic radiation — reduction of 250 times.Anti-glareGlass with a special anti-reflective coating, widely used in aviation, was developed at the plant in Obninsk with Belarusian colleagues.UV protection (50 times less)
This feature is particularly important in conditions of elevated temperature, since under the influence of ultraviolet rays may be damaged strap catapult. In addition to protecting against UV light, the pilot is protected from the harmful radiation of powerful radars close flying aircraft.Enhanced weathering of organic glass (Five times)
On the site of the magnetron sputtering glass turns into metalloopticheskoe multifunctional coating. The light transmittance of not less than 70%.

Increased strength

When tested on the glass hit the object weighing 1.7 kg at 800 km / h Increased strength, flexibility and electrical conductivity is achieved through the addition of materials to fullerenes and nanotrubok.Bolshoy complexity was and uniform application of the composition of the large and curved glass. But the task at NPP "Technology" managed. A special vacuum system. The technology is as follows: the product, as enshrined in the intrachamber snap, revolves around two horizontal magnetrons. First is ion cleaning surface using an ion beam is then layering spraying.

In 2010, the development team "Glasses stealth" received the award of the Government of the Russian Federation for the creation of new high-tech products.

As an illustrative example of the use nano-coating "flashlight" You can bring the latest Russian fifth generation fighter T-50. Along with the carbon-fiber panels bearing structures aircraft, which are also designed in Obninsk, nanostekla make the T-50 into an ultramodern "Stealth aircraft".
