GZ and damage stability. So when a ship is damaged and is arrived at equilibrium, one thing we want is it to have some dynamic stability to withstand the usual weather conditions. In simple words, in damaged conditions, if the vessel does not have any dynamic stability then a slight increase in the heel due to weather conditions can capsize the
The vertical/Z axis, or yaw axis, is an imaginary line running vertically through the ship and through its centre of mass.A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and
Surface Stability of Submarines. A submarine in surfaced condition has to satisfy the same stability principles as that of a surfaced ship. The primary requirement in surfaced condition is that, it should remain afloat even after any kind of damage. Which means, there should be a significant volume of the hull above the waterline.
Static stability is the stability of the ship while at rest. This involves an evaluation of the boat's center of gravity, metacentric height and metacentric radius. Dynamic stability involves the motion of the boat during turning and rolling, where the effects of inertia are taken into account.
A disc-type underwater glider (DTUG) has a highly symmetrical full-wing shape that allows it to move omnidirectionally and have the same hydrodynamic characteristics in all directions in the horizontal plane. These characteristics make the viscous hydrodynamic coefficients measured by conventional methods unsuitable for simulating the omnidirectional and steering motions of the DTUG. To
