Obninsk Research and Production Enterprise Technologiya named after Romashin has launched commercial production of import-substituted components for SJ-100 airliners – cockpit glazing and external lights protection. The glazing uses 100% Russian materials, is fitted with heating to allow flights in any weather conditions and has successfully passed all ground tests, including the bird strike test. Such products were previously supplied for the Superjet from abroad. Structural optics is provided for the SJ-100 prototype, which currently undergoes the flight test.
A set per airliner includes six cockpit glazing components that remain functional at temperatures from −62 to +85 °C. Windscreens and direct vision windows form a sevenplex: four silicate glasses bonded together by three polymer film layers. They withstand bird strike at a speed higher than 570 km/h without depressurization. Side cockpit windows are a triplex made of durable oriented organic glass. Signal and other lights protection on wings, fuselage and tail assembly is made of organic glass.
The SJ-100 is a regional narrow-body jet designed within the system and component import substitution program. The airliner will become another member of the currently operated Superjet type aircraft family. The aircraft with Russian airborne systems has performed its maiden flight on 29 August 2023.
