Effects of X Rudder Area on the Horizontal Mechanical Properties and Wake Flow Field of Submarines
Abstract X rudder is particularly important for submarine maneuverability, but its influence on wake flow field remains largely unknown. In this study, the X rudder was scaled down three-dimensionally to 80%, 85%, 90%, 95% and 100% of the original rudder area with unchanged aspect ratio and installation position of rudder shaft.
