Abstract

Currently, modern turbomachines, for example, aircraft gas turbine engines are equipped with highly intelligent automated monitoring and control systems, including a large number of sensors that control various parameters of the product being operated. In particular, there are sensors that monitor the oscillation frequencies of the most critical structural elements. This paper estimates the ability to determine the support stiffness of a cantilever rod under the two first eigenfrequencies of its oscillations. A similar problem arises in the non-destructive testing of the axial compressor blade root of a gas turbine engine when a certain decision of its further operation possibility or changing its operation mode is can be made on the basis of the blade oscillation eigenfrequencies spectrum. As a result of the implementation of the paper proposed method it was obtained that the identification error does not go beyond 28%, which is quite acceptable for assessing the technical condition of the support in the engine corresponding to the range of existing engines.
