TsAGI Gives 11th Annual Scientific Technical Seminar on Advanced Civil Aircraft Structures

29 September 2020

Since recently, composites have been actively introduced in aviation industry, which is leading to a significant revision of approaches to the design of aircraft structures. The effective use of composites in critical airframe elements, such as the wing and fuselage, is an extremely difficult task that requires new ideas and approaches, innovative techniques and technological solutions. These issues were discussed at the 11th Seminar on Advanced Civil Aircraft Structures, which took place in mid-September in TsAGI Tech Center.

The event was primarily focused on advanced aircraft structures with next-generation composite aircraft skins, which are being developed by TsAGI and co-contractors within RFBR grants and government contracts with the Ministry of Education and Science of Russia and the Ministry of Industry and Trade of Russia.

Mikhail Zinchenkov, TsAGI Deputy CEO and Head of Strength Complex, dwelled on the goals and objectives in the field of promising aircraft designs and on TsAGI research in this field. As a priority, he named research on new hybrid structures using technical condition monitoring and active systems, new design methods based on a multidisciplinary approach and topological optimization.

Alexander Shanygin, TsAGI Head of Laboratory for Advanced Aircraft Structure Strength, enumerated the main principles of creating bionic structures based on a frame (a ‘skeleton’) and flexible skin. The biological ‘skeleton’ bears main mechanic load while elastic skin protects it from environmental factors and performs a number of important auxiliary functions. This design makes it possible to overcome the disadvantages characteristic of modern composites, in particular, their low impact resistance.

Also, Vyacheslav Kazhan, TsAGI Head of Research Department 6, delivered his plenary speech on advanced civil aircraft. Vladimir Vermel, TsAGI Head of R&D Center, which is a part of Research-and-Manufacturing Complex for Manufacturing Facilities and Test Facilities Development, reported on nano-glued joints in aircraft composite structure.

The participants discussed possible ways of cooperation, as well as approaches that allow, through the joint efforts of specialists from different organizations, to advance in solving the problem of creating a new generation of light and reliable aircraft structures.

The seminar was organized by the Laboratory of Advanced Aircraft Structures of the TsAGI Research Complex for Aircraft Strength. It was attended by more than 60 Russian leading industrial, scientific and educational organizations specialized in aviation industry. Among the participants were: JSC Central Research Institute for Specialized Engineering, SibNIA named after S. A. Chaplygin, Ural Works of Civil Aviation, Tupolev PJSC, JSC Myasishchev Design Bureau, Regional Aircraft Irkut Corporation, Kosygin Moscow State Textile University; Ritm JSC, Peter the Great St.Petersburg Polytechnic University; National Research Universities: MIPT, MAI, South Ural State University; and others.
