Damage Stability Model Test for the Advanced Double Hull (ADH) Program.

A series of dynamic damage stability model tests have been performed on a CG-47 hull form filled with a double hull test section. These tests were carried out in support of the static and dynamic stability sub-tasks of the Advance Double Hull (ADH) Project. Various combinations of flooding conditions were investigated in regular beam seas, with and without wind. The model was subjected to regular waves ranging from 2.2 to 12.9 feet, single amplitude, with periods ranging from 5.3 to 19.9 seconds. These regular wave tests performed at the Carderock Division, Naval Surface Warfare Center (CDNSWC) in the Maneuvering and Seakeeping (MASK) basin. Calm water roll decay tests were also performed at the MASK while righting arm tests were performed at the adjacent drop tank facility. These test were performed in order to calibrate the static stability and roll damping characteristics of the physical model to those of associated computational models. (KAR) P. 3
