TsAGI Gets RSF’s Grant to Implement Advanced Project

19 July 2023

Today, supporting fundamental research is a priority in Russia’s strive for leadership in research and technology. An effective way to achieve it is grant support for young scientists—it allows talents to develop their initiatives for the progress of high-tech industries. An example of that is ‘Modeling Unsteady Flow of Intrinsic Bodies’, the research by TsAGI (a part of NRC “Zhukovsky Institute”) that received a grant from Russian Science Foundation (the RSF).

As a rule, aircraft flight occurs in the conditions of unsteady flow, for instance, at maneuvering, strong atmospheric turbulence or wake vortex encounter. At design stage, these factors are considered with different methods, such as numerical modeling. Their successful validation provides the accuracy of the data obtained by scientists. TsAGI experts are to research into this issue.

The project will be carried out by TsAGI and KIAM RAS, and will solve two main scientific problems. First, aircraft unsteady flow modes will be modelled on the basis of new experimental, computational and theoretical approaches. The second work package deals with validating state-of-the-art numerical models and software.

In particular, the project will provide the methods of determining unsteady aerodynamics of aircraft models in wind tunnels. ‘In the course of the project, we will use unique methods to process the results of non-stationary measurements and, in the process, they will be developed to the state of the art. Now we can confidently say that we are expecting some exciting results in this regard,’ said Cand. Sc. Anton Gorbushin, Project Head, Head of Aerodynamics Test Center at TsAGI.

Apart from aviation, unsteady data measurement methods can be applied in other industries and agriculture as well—for instance, to measure cargo weight in road or railway freights, or to measure weight at belt conveyors and packing lines (weight measurement and product rejection). It will be useful to determine loads in obstacle-hit tests of products, etc.

The project was supported by the RSF within the Competition in Fundamental and Applied Research by Individual Research Groups, which is to last three years, from 2023 to 2025.

The RSF’s mission is the financial and organizational support of fundamental and applied research, training of researchers, and development of research communities that lead in a specific area of science.
