N. E. Zhukovsky Central Aerohydrodynamic Institute (TsAGI) completed static tests of the MC-21 aircraft fin made of materials produced by Rosatom’s composite division based on Russian technologies.

At the first stage, TsAGI scientists conducted the initial cycle of endurance tests including the simulation of 10 thousand flights. After that they carried out static strength tests when the fin was exposed to beyond design loads. The results obtained demonstrated full compliance of the performances with the design.

“Over the past seven years, we have created a complete production chain for carbon fiber composites, the only one in Russia, the CIS countries and Eastern Europe, from crude oil to the MS-21 aircraft components. I am proud that the composite division makes a significant contribution to the development of the key project in the Russian aircraft industry,” said Alexander Tyunin, Director General, Rosatom’s composite division.

The results of the tests will be used in a certification report on the strength of the MC-21 fin. The next stage includes testing of the stabilizer made from Russian materials, as well as of domestically produced floors, doors, airstairs, windscreens and window glass of the passenger cabin of the aircraft.
