The paper shows the results of the experimental activity about the dynamics of a stage of a counter-rotating turbine of an open rotor architecture engine. The tests presented here explore the dynamic behavior of a simplified counter-rotating turbine stage. The test results show the dynamic behavior of a counter-rotating turbine stage and highlight the importance of the presence of dry friction for vibration damping.
