Army-2021: TsAGI at the Forum

2 September 2021

Conference on defense industry diversification, seminar for flight dynamics and flight control, and a number of other conferences and round tables—these were the key points of the scientific-and-business program of TsAGI (a part of NRC “Zhukovsky Institute”) at the Army-2021 International Military-Technical Forum.

Focused on discussion of Russia’s defense industry priorities, the forum was held from August 22 to 28 at the Patriot Expo Center (Moscow Region, Kubinka town). Totally, TsAGI employees participated in over 25 forum platforms.

‘Throughout its history, TsAGI has contributed to stronger national defense capability; gratifyingly, we are a part of this vital work ensuring Russia’s security. One of the key defense enterprises, TsAGI has permanently participated in the Army International Military-Technical Forum. We find it important to be involved in the dialogue to inform the world-class experts about our competences. Indeed, this event will set new promising tasks, and we will work together with our colleagues in the industry,’ said Kirill Sypalo, Director General of TsAGI, Corresponding Member of the RAS.

Various departments of TsAGI were involved in Army-2021. The TsAGI Center for Research and Technology Research-and-Manufacturing Complex participated in round tables devoted to the challenges of creating UAVs and robotics, composites and AI. Expert speeches were delivered by representatives from the Department for Measuring Technology and Metrology, from Moscow Research Complex, from the Center for Coordinating and Implementing Defense Programs, etc.

One of the main points of TsAGI’s participation at the forum was the conference titled “Diversification of Military Industrial Complex. Transforming the Production Basis”. At this conference, reports were delivered by Vladislav Granich, Head of Moscow Complex, and Yelena Pudalova, Head of Advanced Development.

A regular seminar titled “Flight dynamics and flight control” was held within Army-2021, organized by TsAGI, MAI and Russian Air Force Academy. The seminar focused on peculiarities of aircraft critical-flight dynamics. Results of research in this area were presented by TsAGI, MAI, Irkut Corporation, and MiG Corporation.

In his speech, Pavel Desyatnik, Head of Sector at TsAGI Department for Aircraft Flight Dynamics and Control Systems, spoke about method developed by the Institute for semi-natural modeling of non-maneuverable aircraft critical flight modes. He presented a mathematical model of aircraft flight dynamics, based on peculiarities of aerodynamic performance at high angles of attack. The data was obtained with wind tunnel tests, and was corrected according to flight test results. Importantly, the model allowed for reproducing various types of stall, including deep stall. His report also dealt with current difficulties related to flight simulation of linear accelerations and angular accelerations, as well as assessment of methods for modeling their impact on critical flight modes.

‘TsAGI has developed reliable mathematical models which capture precisely all the nonlinear and non-stationary aerodynamic characteristics at critical modes. This is very important both for research and for training. Although flight simulators can hardly be used for simulating overload caused by aircraft upset, our specialists have successfully developed control algorithms for simulator mobility mechanism. These algorithms provide quite realistic sense of overload, and accurately-simulated visually-perceived motion process,’ said Aleksandr Yefremov, Doctor of Technical Sciences, Chairman of the Meeting, Head of MAI Department.

The next seminar on flight dynamics will be held this autumn at TsAGI and will be devoted to the 60th anniversary of the Institute’s Department for Aircraft Dynamics and Control Systems.

Army-2021 is the International Military-Technical Forum organized by the Ministry of Defense of the Russian Federation. This year, the event was held for the seventh time. It focuses on promoting the Ministry’s technical renovation and its better efficiency, on stimulating innovative development of Russia’s defense industry, on activities of young talents from research organizations of the Ministry and the defense industry, on developing military-technological international cooperation, on patriotic education, on forming positive image of the Ministry as a modern and dynamically developing structure, and on popularizing the Russian Army service.
