| The article studies the interaction of parts of bladed machines in a gas flow, accounting for mechanic connections. The issue is studied by considering a 2D mathematical model of a homogeneous bladed crown. The contribution of the aerodynamic force into the development of self-oscillation processes is demonstrated. The main results are applied to a realistic object with the parameters that are used in computations and diagrams in the course of the analysis. |
