The twin hybrid autonomous underwater vehicle (THAUV) is a novel type of unmanned platform that consists torpedo-shaped hull and actuated by two buoyancy engines thrusters proposed in this paper. THAUV was designed to have faster speed generated the thrusters. on each airfoil are mainly responsible for diving surfacing motion, drive along horizontal plane. capable carrying more instrumentation ...

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...
