Parametric Investigation on the Influence of GM, Roll Damping, and Above-Water Form on the Roll Response of Model 5613
Abstract
A parametric investigation on the influence of above water hull form, vertical center of gravity, and bilge keel damping on the roll response of a notional combatant hull form was pursued via model testing of a 1/32nd scale ship model in the Maneuvering and Seakeeping (MASK) basin of the Naval Surface Warfare Center, Carderock Division (NSWCCD). Model 5613 was built with an underbody that could be joined at the waterline with three different topside hull forms - a V-flare design, a "tumblehome" wave piercing design, and a "conventional" wall sided design. The models were tested in oblique regular waves at speeds ranging from zero to 25 knots full scale. The results are presented as plots of roll damping, non-dimensional transfer functions, and tables of response amplitudes for roll and transverse accelerations at the bow, center of gravity (cg), and stern.
