Abstract:

A computer program called TRIBRID is described which can rapidly calculate the smooth water resistances of some advanced hybrid and tribrid ship concepts that are supported by buoyant, dynamic, and aerostatic forces. These forces are produced by one or more hull-strut combinations similar to a demi SWATH in conjunction with large hydrofoils andor air cushions. For a given displacement and shape, the size of each concept is determined and various drag components along with some interference drag are then calculated for a calm water, fixed zero trim and free to heave operating condition.
