THE PERFORMANCE OF HIGH-SPEED RUDDERS IN A CAVITATING ENVIRONMENT

Force and moment coefficients for six high-speed craft rudders are presented. These experimental results indicate that the rudder section shape has little effect on the maximum lift coefficient, although the drag and rudder stock torque are influenced by the section shape. Lift, drag, and rudder stock torque are all significantly affected by variations in the cavitation number. Details of the six rudder designs are presented and the relative merit of the designs is discussed. Recommendations for further investigation of high-performance craft rudders are included.
