Registration Date 20-03-2023 Organization GS Pisarenko Institute of Strength Problems of the National Academy of Sciences of Ukraine popup.description2 Methodological approaches to the experimental determination of the dissipative properties of structurally heterogeneous materials, the damping capacity of the blades of turbomachines under conditions that are as close as possible to the operational and aero-damping characteristics of the compressor grids of the blade profiles have been developed. The results of an experimental study of the influence of low and elevated temperatures on the dissipative properties of polymer composite materials are presented. The results of the study on determining the influence of nanostructured coatings on the damping capacity of core models of structural elements of the working blades of compressors of aircraft gas turbine engines for different vibration frequencies and temperatures are presented. An analysis of the features of air damping of compressor and fan blades and the conditions for the occurrence of subsonic flutter during bending and torsional vibrations was carried out.  Product Description popup.authors popup.nrat_date 2023-03-20 Close
