The Obninsk plant "Tekhnologiya" has launched a robotic laser complex that removes the conductive coating from the glass for SJ-100 and MS-21 cockpits. The installation is already operating in the serial production of electrically heated glazing.
The complex was created by "RT-Tekhpriemka". Inside, there is an industrial robot and a laser scanning module with a solid-state ytterbium laser. The processing error is stated to be 0.9 mm, and the working field is 2000 × 1600 mm. The laser removes the coating without contact, so that the glass heats evenly and does not fog up during flight.
Boeing and Airbus have been using similar technologies since 2005. Robotic laser processing of cockpit and fuselage elements is a global standard for modern aircraft manufacturing.
At the same time, the technology itself existed in Russia before, but only for piece military production. It was not previously used on civilian aircraft, as the glazing was purchased abroad.
OAK explained that the windshield of the MS-21-310 medium-haul aircraft cockpit is one of the most technologically complex elements. It is not just glass, but a high-strength pentaplex designed for extreme loads.
It is a "sandwich" of three layers of glass and two adhesive interlayers. The two outer layers are made of silicate glass, and the inner layer is made of polycarbonate.
