    Abstract
  • A novel hydrodynamic layout based on anisomerous bow rudder was firstly proposed for strongly maneuvering underwater supercavitating vehicle because aft rudder is short of effectiveness.In the layout, straight-and-level flight and strong maneuverability motion were considered.Bow rudder with 2 DOFs controlled orientation with deflexion in level, and controlled pitching or depth with up-and-down motion.Anti-roll fin appended below the rudder generated imbalances torque.For validating the dynamic characteristic of the design layout, related simulation on a supercavitating vehicle was carried out.The attenuation of remanent roll moment completes in about 0.1 s, and ultimate roll angle is less than 0.1°.Analytical result shows that the novel layout can markedly improve control rudder effectiveness.
