Horizontal Zigzag maneuverability of UUV in limited space

Unmanned Underwater Vehicles (UUV) is a useful tool for underwater exploration and scientific research in ocean engineering, and the maneuverability of UUV attracts many research concerns. In this paper, maneuverability simulation of a full-size UUV is conducted, where the horizontal motion equations is built by hydrodynamic modeling approach. Simulation results show the largest motion distance in the radial direction of horizontal zigzag maneuver in different speeds and rudder angles. It also reveals characteristic values of Zigzag maneuver in limited water space, which makes contributions to feasible maneuverability tests in small-size tank. Based on this method, a kind of handy calculation software could be developed to quickly generate feasible maneuverability data in any limited space.
