ONPP "Tekhnologiya" named after A. G. Romashin (part of Rostec) tested the strength of the new cockpit glazing of the Russian MC-21 aircraft. It successfully withstood a bird strike at a speed of over 600 km/h.
Similar products, providing comfortable visibility from the cockpit and protection, are also installed on another domestic airliner — SJ-100.
The production volumes of Russian passenger aircraft will increase. Therefore, we plan to increase the supply of glazing for "Superjets" by 2.5 times, and for MC-21 by more than 11 times by 2028.
The high strength of the glazing is guaranteed by the technology of ion-exchange strengthening of silicate glass. It allows creating glazing with complex geometry, which is 8 times stronger than ordinary glass. Thanks to this, the cockpit can withstand a likely encounter with birds in the air, which increases flight safety.
The windshield of the MC-21 cockpit is a seven-ply structure — four silicate glasses glued together with a polymer film. It has an electric heating function. Thanks to this, the glazing always maintains high optical properties and does not fog up during temperature changes.
