Hydrodynamic added mass determination and attitude estimation of the Seahog - a remotely-operated underwater vehicle
… When a vehicle is undergoing an unsteady motion underwater, extra resistance is experienced by the vehicle. This resistance differs to the drag forces as it is independent of the vehicle’s relative velocity. This resistive force is known as the added mass. Added mass covers both the …

Virtual Planar Motion Mechanism Testing of 8:1 Spheroids
PMM testing is a method used to identify the added mass and damping coefficients used in the equations of motion of a vehicle by attempting to decouple the forces on a body due to velocity and acceleration as a result of creating "hydrodynamically pure" velocities and accelerations. This makes it …
