Abstract:

Experimental studies were conducted on four propellers in the partially submerged condition. Three were existing NSRDC supercavitating propellers, and one was an eight-bladed propeller, specifically designed for partially submerged operation. Experimental results show that the thrust and torque are proportional to the submergence, and that efficiency is essentially independent of the submergence. Also, Froude effects are important for certain speed regimes. Author
