A Comparison of Fatigue Test Techniques for Gas Turbine Oils - (Report of the CRC-Aviation Bearing Fatigue Panel of the Group on Gas Turbine Lubrication)
A number of specimen life performance tests were conducted on three test lubricants selected to demonstrate their gross ranking capabilities. The results indicated that the test rigs should be used only for gross ranking. A large difference in magnitude of life values were obtained even though agreement in gross ranking was obtained by three out of the five participating laboratories. Further testing is recommended under preselected test conditions and lubricants.
