Pisarenko Institute for Problems of Strength of the National Academy of Sciences of Ukraine popup.description2  During the implementation of the scientific and technical project, a methodology for preventing the destruction of the pair-shrouded turbine blades of modern aviation gas turbine engines was developed. Developed computational models of pair-shrouded blades and methods of experimental study of their damping ability and vibration tension and the results of the calculation and experimental studies of the influence of the disorder of oscillation frequencies and shroud parameters on the dynamic tension of the blades were presented. Recommendations for optimal conditions for the coupling of the shrouds as a criterion for preventing the destruction of pair-shrouded blades were formulated. The work was carried out in the scientific and technical cooperation with SE "ZMDB" Progress" named after Academician A.G. Ivchenko. The final report has been submitted to the partner. The developed scientific and technical products will be used in the design of new and refinement of existing aviation gas turbine engines, as well as the analysis of the technical condition of the blades after their resource is exhausted.
