| Summary: | aircraft gas turbine engine were investigated experimentally. changing bearing damping and stiffness coefficients were well Great amount of air bubbles were observed at the oil return helped to suppress vibrationamplitudes at critical speeds. lines. matched with the coastdown plots of the test runs. The model simulations. The damping coefficients changed with respect to the rotational speed. Damping coefficients of respect to the rotational speed. High oil supply pressure Rotordynamic model(XLROTOR) for Gas Generator and Power squeeze film dampers reduced effective support stiffness with squeeze film dampers were mainly determined by the XLROTOR The rotordynamic coefficients of squeeze film dampers of an Turbine were constructed. The XLROTOR response plots with |
