The specialists of Obninsk-based Technologiya research and development enterprise have developed the metal-optic nano-coating for the canopy of combat aircraft, which protects the pilots against radiation and intense solar radiance during altitude flights. It has been declared by the Director of Steklo research and development division of Technologiya, Valery Temnikh, Lenta.ru reports.

According to him, the new coating should be applied on the inner side of the canopy and it decreases the warmth of solar flux by 40% and the radiation – by 30%. In addition, the coating decreases the electromagnetic emission 250 times and increases abrasive wear resistance and wear resistance. "Various metals are applied to the canopy and the light transmittance should be at least 70% after this procedure", - Temnykh said.

Besides, the new coating will help decrease the cockpit’s radar signature by 30%. According to Temnykh, the radio signal is reflected by the finished glass and the quenched signal spreads in different directions. The overall coating’s thickness is about 80 nanometers. Technologiya uses special magnetron deposition equipment for applying the coating to the canopy. The coating will be applied to the canopy of Т-50 (PAK FA), МiG-29К, Su-30 fighters and Su-34 bomber.

The mass-media have reported in late March 2012 that Technologiya have used gold sputtering in order to protect the pilot of T-50 against radio waves and solar radiance. According to the Chief Designer of Technologiya, Vladimir Vikulin, indium and tin are also used besides gold. The thickness of one layer is 20 nm, and the overall coating’s thickness is around 90 nm.
