STRESSES IN THE BLADES OF A CARGO SHIP PROPELLER

The problems of propeller-blade failures on a single-screw ship of the "Lichtenfels" class is solved by full-scale measurements, model tests and a calculation with elementary theory. The results show that the failures are caused by wake-induced forced oscillations of the blades. The agreement of the results of the three investigations is acceptable. It is further shown by model tests in regular and irregular waves that the stresses in a seaway can be much higher than those in smooth water.
