Naval Architecture, Theory of
Naval Architecture, Theory of
the science that studies the seagoing abilities of ships, both in a state of rest (ship statics) and in motion (ship dynamics); the application of the laws of theoretical hydromechanics and aerodynamics to ships. The divisions of ship statics are buoyancy, unsinkability, and static stability; divisions of ship dynamics include dynamic stability, rolling of a vessel, speed/power ratio (performance coefficient), maneuverability, and ship launching. The works of the Russian scientists L. Eiler, S. O. Makarov, A. N. Krylov, V. L. Pozdiunin, and I. G. Bubnov, among others, constitute important contributions to the development of the theory of naval architecture.
