... compressor support and ( b ) for low pressure turbine support The paper presents the feasibility study of electromagnetic systems for the control of the lateral vibration of aero-engines. The analysis focuses on a solution in which the weight of the rotor is supported by rolling bearings...

...Michael Flouros Trends in aircraft engine design have caused an increase in mechanical stress requirements for rolling bearings. Consequently, a high amount of heat is rejected, which results in high oil scavenge temperatures. An RB199 turbofan bearing and its associated chamber were modified...
