Abstract

The paper describes the results of the experimental study of destruction of the foil gas dynamic bearing for a rotor of the gas turbine power plant. An analysis of temperature field, displacement and torque in the bearing was performed depending on the load and at the moment of destruction. The ultimate bearing capacity and the range of stable operation were determined.
