Resistance and Seakeeping Performance of New High Speed Destroyer Designs

Résumé du livre

Results of calm water resistance tests for two new destroyer designs are compared with data for the DD692 Class (long hull). Heave and pitch measurements in three wave lengths, which are reported for the better of the two new designs, show its marked superiority over 692 in all but the very low speed range. A check of the roll characteristics shows that the gain in seakeeping performance is obtained at small sacrifice in roll stability which may be overcome by design refinement. It is concluded that this brief study has evolved a highly practical destroyer form which has markedly reduced heave and pitch with some increase in resistance at low speeds and a reduction in resistance at high speed. This form, which merits consideration for additional study, holds greater seakeeping potential for ASW missions than any other advanced surfaceship concept previously studied. (Author).
