In the proposed study a fast method to predict the seakeeping behavior of catamarans in waves is described and applied for the sensitivity analysis of its performance in the framework of a preliminary design process. The method is based on two-dimensional potential flow theory in which viscous forces are considered through a cross-flow drag...

A new viscous lifting-line method for three-dimensional supercavitating hydrofoils is presented. The method is designed to allow for the strong nonlinear hydrodynamic characteristic of two-dimensional supercavitating sections. These nonlinearities, manifesting as sudden variation of the sectional lift-curve slope, are included in the numerical...

The paper presents a framework for set-based design under uncertainty and demonstrates its viability through designing a super-cavitating hydrofoil of an ultrahigh speed vessel. The framework achieves designs that safely meet the requirements as quantified precisely by superquantile measures of risk (s-risk) and reduces the complexity of design...
