A Linear Maneuvering Model for Simulation of Slice Hulls

A maneuvering mathematical model is generated for a baseline SLICE ship by calculating the linear hydrodynamic coefficients using existing semi-empirical methods for the pods. Struts are modelled as flat plates attached to the pods. Pod/strut combinations are translated to the ship's reference...

Summary:A maneuvering mathematical model is generated for a baseline SLICE ship by calculating the linear hydrodynamic coefficients using existing semi-empirical methods for the pods. Struts are modelled as flat plates attached to the pods. Pod/strut combinations are translated to the ship's reference point generating the ship's linear hydrodynamic coefficients. Eigenvalues of the horizontal equations of motion are used to evaluate the stability of the base line configuration. Rudder effects are included and steering characteristics are investigated for various rudder aspect ratios and locations. Rudder placement is discussed in the context of practical considerations and model test results.
