MS-21 got to a sanctions hole


Developers of the perspective Russian liner faced a problem: because of restrictive measures of the USA deliveries from America and Japan of materials for a composite wing are stopped. What means the ban on deliveries of the western composites and what they can be replaced with for the project? Photo: Marin already reported to Lystsev/TASS In United Aircraft Corporation that the MS-21 project will be implemented with a composite wing from domestic components. When to wait for import substitution in this area, the company did not specify. The first flight of MS-21 made in May of last year. Now three liners, one more — at an assembly stage are constructed. And the stock of composites which remained with developers is calculated on only six planes, told the Kommersant newspaper sources in the aircraft manufacturing industry. About what can be made in such situation, the aviation expert, Candidate of Technical Sciences, the ex-designer of Sukhoi Design Bureau Vadim Lukashevich says: Vadim Lukashevich the aviation expert, Candidate of Technical Sciences, the ex-designer of Sukhoi Design Bureau "At China now a situation with composites is better, than in Russia. We can try to be given up China in respect of replacement to America and Japan, but any design in design is already put on certain materials. Respectively, if now we change materials, we change properties, technologies, the producer, it is really a difficult task, it is very fraught". The Chinese components it is twice thicker and heavier Japanese and American, and it is unclear whether there is a sense in such replacement. Was considered allegedly and the radical option — in general to refuse composites in MS-21 and to redesign it in metal. However, then the liner will lose the main competitive advantage — the extended composite wing which increases profitability of the car and increases width of salon. And the project which total cost the Audit Chamber estimated more than at 400 billion rubles can be to nobody necessary. In OAK insist that the wing will remain composite. According to the president of corporation Yury Slyusar, work on creation of composite designs from the Russian materials goes since 2014. These solutions are found at a stage of transition to mass production and will take root into the MS-21 program. When it occurs, is not specified. How many it is necessary for time to market composite designs for aviation industry from the Russian components, the chief of laboratory of composite materials and designs of research department of department 101 MAI Egor Nazarov tells: Egor Nazarov the chief of laboratory of composite materials and designs of research department of department 101 MAI "I would call term approximately in seven-ten years from which about three years it will be required on localization of production of raw materials for carbon fiber and the most carbon fiber, and about five-seven years on localization of production of components binding. Already now in a row the Russian enterprises which are engaged in development and production of composite materials cumulative investments make flogging
