ANALYTICAL AND EXPERIMENTAL TECHNIQUES USED AT HSMB FOR SURFACE SHIP DIRECTIONAL STABILITY AND CONTROL STUDIES

Standard techniques and procedures have been developed at HSMB for conducting detailed design and evaluation studies of the directional stability and control characteristics of proposed and existing surface-ship designs. The overall method consists of PMM tests with large surface-ship models (ranging from 18 to 27 feet in length to determine complete sets of hydrodynamic coefficients; formulation of mathematical models therefrom based on Standard Equations of Motion; and conduct of maneuvering studies employing the mathematical models in conjunction with computer simulation techniques. The history of the technology development leading to the adoption of the HSMB techniques is presented; the relative merits of these techniques are compared with those of other corresponding predictive techniques actively used such as free-running model test techniques; the facilities, apparatus, and procedures used for the model experiments and computer simulation studies are described; and typical examples are given of the various analyses made and evaluation studies performed.
