TsAGI Specialists Speak at 5th All-Russian Conference of Young Scientists in Mechanics
12 October 2022
Specialists from TsAGI (a part of NRC “Zhukovsky Institute”) took part in the 5th All-Russian Conference of Young Scientists in Mechanics which was held in Sochi in September. The event was organized by Lomonosov Moscow State University, Moscow State University’s Institute of Mechanics, and the Russian National Committee on Theoretical and Applied Mechanics.
Ivan Amelyushkin, Senior Researcher for Aerothermodynamics of Hypersonic Aircraft and Aerospace Technology (TsAGI), presented a paper on the features of icing and snow saltation (i.e. particles’ lifting from streamlined body surface), co-authored by M. Kudrov and A. Morozov (MIPT). In particular, Amelyushkin calculated the properties of ice-phobic coatings that provide an anti-icing effect as supercooled droplets hit streamlined body surface within wide velocity range. He also showed the areas of increased snow concentrations in boundary layer. The data can become a basis against aircraft structural unit icing. The paper received the first-degree award at the conference.
Andrey Katunin, Leading Engineer at TsAGI Moscow Complex, presented a new method to determine wing lift force by optical measurement of velocity field in Prandtl tip vortex (the paper was co-authored by A. Airapetov and V. Strekalov). The scientists proved the applicability of the visualization videographic method for determining magnitude of lift due to its correspondence to Prandtl tip vortex circulation. This could become an alternative to air and hot-wire anemometry in wind tunnel tests to determine wing aerodynamics.
Roman Akinshin, Junior Researcher for Aircraft Aeroacoustics and Ecology (TsAGI), presented Gerber-code numerical modeling of rotor tonal noise (co-authors: M. Zaitsev, V. Titarev and G. Faranosov). Domestic rotorcraft need to comply with the increasingly stricter requirements for environmental noise—yet acoustic test capabilities are rather limited, especially those for in-flight condition. Therefore, there is ongoing demand for development of methods of numerical modeling of rotor aeroacoustic characteristics. TsAGI scientists determined with numerical solution of the Euler equations the four-blade rotor aeroacoustic characteristics in hover mode.
The conference also included a presentation of study of streamlined six-blade rotor with numerical solutions of Navier-Stokes equations (by E. Pigusov, A. Belchikhina and S. Kuzin), and the work on experimental determination of streamlined wing model noise sources with non-synchronous measuring with microphone array (M. Demyanov and O. Bychkov).
Over 100 people participated in the Conference, including employees from research enterprises, universities; students, professors and academicians from Moscow, St. Petersburg, Perm, Nizhny Novgorod, Novosibirsk, Ufa, Krasnodar, Khabarovsk, Tomsk, etc.
