Abstract

The study describes investigation of interaction between components of blade engine accounting mechanical links that remains in gas flow. Analysis has been made with 2D mathematical model of homogeneous blade row. The study shows investment of aerodynamic forces to development of self-induced vibration. Basic conclusions put into a real object and the paper shows computations and plots for the object.
