Results of an investigation into nozzle shapes, reducing the flow rate through the propeller, are presented. The purpose of this reduction is to prevent the occurrence of cavitation. The investigation was carried out under Contract No. N62558-3960 of the U.S. Department of the Navy, David Taylor Model Basin, through its U.S. Navy European Research Contract Program. A theory is described for the numerical calculation of systematic series of nozzle shapes. The shape of the nozzles was chosen to produce ram pressures at the propeller plane in order to delay the onset of cavitation. Tunnel experiments were carried out with the above nozzles.
