Hull Form Modifications to the LSD-41Design Based on Longitudinal Wave Cuts and Wave Resistance Minimization,

摘要

As part of the effort in direct support of concept design development for the LSD-41, the David W. Taylor Naval Ship Research and Development Center (DTNSRDC): Conducted longitudinal wave-cut experiments at the 14,900 ton displacement and at 22 knots, ship scale; Developed low-wave-drag hull forms as variations from the geometry of Model 5011-1 by making use of a wave-drag minimization theory and wave-cut data. Developed an additional low-wave-drag hull form without change in beam, draft and length, but with a displacement increase from 14,900 to 15,500 tons; and Performed an analytical estimate of EHP and SHP requirements for the hull form. This report also presents a discussion of the combined theoretical and experimental approach to hull form improvement used to improve the hull form of the LSD-41 Class.
