Abstract:

Model experiments were conducted to determine the performance of model propeller 4407 in partially-submerged operation for a range of shaft yaw angles. All experiments with the highly skewed propeller were conducted at 30 percent submergence and at 19.5 degrees shaft inclination from the horizontal. The purpose of the experiments was to determine the effects of shaft yaw angle on the propeller performance. Test results showed that shaft yaw angle could yeild a 15 percent increase in efficiency based on forward thrust production. Author
