Abstract

The Unmanned Undersea Vehicle(UUV) which was called Manta-type Unmanned Undersea Vehicle(Manta UUV) had taken the shape of manta. Manta UUV was proposed by Bae et al.(2008). Manta UUV is based on the same design concept as Manta Test Vehicle(MTV), which was originally built and studied by the Naval Undersea Warfare Center(NUWC) in the USA. Effects due to hovering thrusters attached Manta UUV of large angle of attack are measured from model experiment in circulating water channel. Characteristics of various motions are evaluate to apply mathematical model for numerical simulation based on Bae et al.(2009a). Numerical simulation is carried out to calculate hovering motion due to only hovering thruster, lateral motion due to only current, composite motion due to both hovering thruster and current. Lateral motion due to current is calculated to apply velocity variables, which are defined as relative velocity due to angle of current, to mathematical model, and hovering motion due to hovering thruster is calculated to apply results of model experiment to mathematical model.
