The paper, "Submarine Hull Form Optimization Case Study Using Parametric Relationships, a Ducted Lifting-Line model, and a Genetic Algorithm," was published in the Naval Engineers Journal of November 2000. The paper is a case study evaluating the benefits of full stern submarines. First the authors conducted a parametric-based arrangement study using estimates of volume, area, and weight, as well as machinery configuration requirements. From these arrangements approximate required stern fullness and length to diameter ratios for enclosing the arrangements were determined. The variants having the best parametric-based maximum speed were then used as inputs to the hydrodynamic/optimization technique, which employs a ducted lifting-line propeller code. This code is used as an evaluator module for a multi-objective (Pareto) genetic algorithm. Two resulting optimal variants (full and tapered) were selected according to their similarity to those of the arrangements study. Using power coefficients generated by the propeller code, maximum submarine speeds were calculated. The authors determined that potential benefits exist for submarines with non-traditional, fuller sterns, namely: higher submerged speed and greater power efficiency.
While the authors concede that their conclusions are not definitive, their study demonstrates that there is reason to support a more thorough analysis and possibly an experimental testing program. This paper is definitely in the tradition of advancing the knowledge and practice of naval engineering and in keeping with the highest standards of the Naval Engineers Journal. The authors are indeed worthy of the Society's 2000 "Jimmy" Hamilton Award.
