Performance of an Inclined Shaft Partially-Submerged Propeller Operating over a Range of Shaft Yaw Angles,

摘要

Model experiments were conducted to determine the performance of model propeller 4407in partially-submerged operation for a range of shaft yaw angles. All experiments with the highly skewed propeller were conducted at 30percent submergence and at 19.5degrees 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 15percent increase in efficiency based on forward thrust production. (Author)
