Some model tests have been carried out in a free-surface cavitation tunnel with a 3-bladed super – cavitating propeller mounted on a special blade dynamometer to measure the fluctuating blade loads in oblique flow over a range of cavitation numbers. The experiments showed that the vibratory forces on the blades decrease in cavitating conditions. The results were analysed on the basis of a quasi-steady approach; empirical correlation factors were derived which may be used for approximate predictions of blade thrust and torque fluctuations of similar inclined shaft propellers. Some additional observations have been made on the effects of a narrow wake field and propeller ventilation.
