Estimating the Hydrodynamic Characteristics of the Dorado Remote Minehunting Vehicle

Abstract

The hydrodynamic forces on the Dorado semi-submersible remote minehunting vehicle are estimated and provided in a form that can be used in a six degree-of-freedom vehicle simulation. The forces apply to either old or new versions of the control planes. The lift(from flow curvature in a tum) and drag of the self-aligning fairings on the snorkel mast are accounted for as a function of vehicle depth. Hydrodynamic coefficients are used for all but the mast effects, where a rational flow model is used. Deficiencies in the control derivatives estimated by the DERIVS/DSSP20 programs are identified and overcome.
