At the Salyut production complex of the United Engine Corporation, a program has been developed and implemented that allows reducing the volume of field tests. With its help, for the first time in the engine industry, mathematical modeling of self-oscillation of compressor blades of gas turbine engines was carried out. The project became a finalist for the CIPR Digital 2024 award. 

Employees of the experimental design bureau of the Salyut PC, together with the Lomonosov Moscow State University, have developed a methodology for timely detection and correction of self-oscillations (flutter) of the working blades of gas turbine engine compressors at the design stage. 

Based on this technique, software was created for automatic mathematical calculations. The program has already been tested and is being used for engine development. 

"The developed software makes it possible to obtain a significant economic effect from reducing the volume of tests and contributes to improving the reliability of the engine. With the help of our methodology, for the first time in the domestic engine industry, the impeller of the first stage of a low-pressure compressor was detuned from self-oscillations only using numerical modeling. Usually, two or three cycles of full-scale tests were necessary for this," said Stanislav Chepiga, head of the design bureau of the Salyut PC of the UEC. 

The project of the employees of the PC "Salyut" of the UEC was shortlisted for the CIPR Digital-2024 award in the nomination "Digital breakthrough in industry". A total of 480 applications were submitted for participation in the competition. According to the results of the review by the expert commission, only five projects became finalists in each of the nominations. 

CIPR Digital-2024 is the fourth annual business award in the field of digital technologies, which is aimed at popularizing Russian projects and developments. It is traditionally held within the framework of the conference "Digital Industry of Industrial Russia" with the support of the Ministry of Finance of Russia, the Ministry of Industry and Trade of Russia, the Ministry of Natural Resources of Russia and ANO "Digital Economy". 

As previously reported, UEC enterprises are actively implementing digital technologies in various areas today, in particular, the transition to digital certification is underway. The digital twin and computer modeling will help reduce the volume of field tests and accelerate the certification of aircraft engines, specifically PD-8 for the import-substituted passenger liner SJ-100. 

Computer simulation allows for virtual testing of both individual components of the power plant and the system as a whole. This way you can check the performance of the power plant in case of foreign objects, such as birds.
