Mission-based hull-form and propeller optimization of a transom stern destroyer for best performance in the sea environment
An overview is presented of the activities conducted within the NATO STO Task
Group AVT-204 to “Assess the Ability to Optimize Hull Forms of Sea Vehicles for the Best Per-
formance in a Sea Environment.” The objective is the development of a greater understanding of
the potential and limitations of the hydrodynamic optimization tools. These include
low- and high-fidelity solvers, automatic shape modification methods, and multi-objective optimiza-
tion algorithms, and are limited here to a deterministic application. The approach
includes simulation-based design optimization methods from different research teams.
Analysis tools include potential flow and Reynolds-averaged Navier-Stokes equation solvers.
Design modifica- tion tools include global modification functions, control point based methods, and
parametric modelling by hull sections and basic curves. Optimization algorithms include particle
swarm optimization, sequential quadratic programming, genetic and evolutionary algorithms. The ap-
plication is the hull-form and propeller optimization of the DTMB 5415 model for significant
conditions, based on actual missions at sea
