SIMULATION OF BENT TRAILING EDGES OF PROPELLERS BY SHOT BLASTING

Bent trailing edge of propeller blades was studied from the view point of plastic deformation caused by cumulative impact load due to cavitation. It is found that the geometrical shape and microstructure of bent trailing edge of propeller blades are similar to those by shot blasting. These facts not only throw light on the mechanism of bent trailing edge but also lead to a simulation method. This simulation method will be used for studying the intensity of load due to cavity collapse quantitatively and for developing an effective prediction method of both bent trailing edge and cavitation erosion of propellers.
