Rudder Design of Underwater Glider with Diamond Wing

Owing to the superior hydrodynamic characteristics of an underwater glider designed with diamond-wings in comparison with the installation of conventional swept-wings. This article successively engages in the design and analysis of the hydrodynamic performance of the tail rudder adaptive to such kind new type underwater glider. Four kinds arrangements of X-shaped rudders have been analyzed and compared for the lifts, drags and lift-to-drag ratios by using the software package STAR-CCM+. The hydrodynamic performance of the simulation results showed that the 45° X-rudder is most conducive to the UG with diamond-wing.
