INVESTIGATION OF THE FATIGUE BEHAVIOR OF LARGE PROPELLERS

The report summarizes the findings of an experimental study on the fatigue behavior of a full-size aircraft-carrier propeller and a patrol craft propeller. Supplementary data on the fatigue characteristics of the manganese bronze propeller material were determined. Fatigue life predictions based on nominal stress and fracture mechanics concepts are analyzed and discussed. There is evidence that with accurate inputs as to stress levels and service loadings, the fatigue life of large propellers could be predicted from specimen data using a fracture mechanics approach.
