Su-57 fighter jet gets advanced stealth coating
https://www.mycity-military.com/posting.php?mode=reply&t=57918 Citat:A new composite material with enhanced radar wave absorbing properties was used to make the cockpit canopy of the most advanced Sukhoi Su-57 multirole fighter jet and the Tupolev Tu-160 strategic missile-carrying bomber, Russia’s state hi-tech corporation Rostec told TASS on Friday.
The innovative glass coating has been developed by specialists of the Obninsk-based Technologiya R&D Enterprise (part of RT Chemcomposite Group within Rostec).
"It doubles radar wave absorption and reduces the aircraft cockpit’s radar signature by 30% Currently, the coating is applied to the canopy of T-50 (Su-57 aircraft since August 2017), Su-30, Su-34, Su-35, MiG-29K and Tu-160 planes," Rostec said.
The coating is made of metal oxide layers 70-90 nm thick. In addition to reducing visibility to enemy radars, it protects the pilot during the flight from the impact of ultraviolet, thermal and other negative factors, Rostec stressed.
"The coating weakens the thermal component of solar radiation by more than three times while the integral transmittance index in the visible range makes up no less than 65% and the impact of the ultraviolet component drops by more than 4-6 times," the hi-tech corporation said.

Russian media announced on Friday that it had significantly improved the stealth on its Su-57 fighter jet by applying a coating to the glass canopy on the cockpit, as well as similar upgrades to its Tu-160 nuclear bomber.
Russia's state-owned defense corporation Rostec told Russian media the new coating "doubles radar wave absorption and reduces the aircraft cockpit's radar signature by 30%" and added that Russia's Su-57, Su-30, Su-34, Su-35, and MiG-29K jets already have the upgrade.
But none of those jets, including the Su-57, which Russia explicitly bills as a stealth fighter, are considered that stealthy by experts contacted by Business Insider.
While Russia's Sukhoi fighter/bombers have enviable maneuverability and serious dogfighting capability, only the US and China have produced true stealth fighters.
A stealth scientist working on US aircraft previously reviewed pictures of the Su-57 and concluded in an interview with Business Insider that Russia had hardly even tried to make the plane unobservable to radar.

"Други уговор за производњу 13 борбених авиона Су-57 за руске ваздухопловне снаге биће потписан следеће године, изјавио је у сриједу извор у руској индустрији за производњу зракоплова.
"У 2020. години планирамо потписати други уговор за производњу и испоруку 13 борбених авиона Су-57, од којих су неки опремљени моторима другог ступња", рекао је он. "Прелиминарни временски оквир за нови уговор је пет година."
Први уговор предвиђа испоруку два авиона пете генерације у периоду 2019-2020.
"У складу са уговором потписаним 2018. године, један серијски авион Су-57 са моторима прве етапе биће испоручен авионима ове године, други авион који има исти тип мотора 2020."
Произвођач авиона, Унитед Аирцрафт Цорпоратион, уздржао се од коментара на извештај."
