Experimental evaluation of shft angle and immersion effect on Surface Piercing Propeller's hydrodynamic characteristics

The paper presents the results of experimental development of 4 blade Surface Piercing Propeller (SPP) by authous in the course to evaluate the effect of operational characteristics such as shaft angle , Propeller blade immersion, cavitations number on the torque , thrust and efficiency of disign propeller , the results of experimental model tests with theoretical investigation are presentes for application of SPPin high speed craft Propulsion system.
