SYSTEMATIC RESISTANCE EXPERIMENTS WITH TAYLOR MODELS HAVING A BEAM-DRAFT RATIO OF 4.50 (SYSTEMATISCHE WIDERSTANDSVERSUCHE MIT TAYLOR-MODELLEN MIT EINEM BREITEN-TIEFGANGSVERHALTNIS B/T = 4.50),
Abstract
To estimate the resistance of cargo vessels it is often necessary to use the results of systematic model tests; with the aid of the latter it is possible to ascertain the effect of the variation of individual form parameters upon the resistance and thus to choose the principal dimensions of a vessel in such a manner that a relatively favorable resistance is to be expected. One of these systematic test series was undertaken by Taylor in the years 1907-08; the results obtained are published. These model tests cover ships with a coefficient of fineness C sub p = 0.48-0.86 and breadth-draft ratios B/T = 2.25, 2.92, and 3.75. Test results obtained with the B/T ratio of 2.92, however, were not published by Taylor. During the years 1948-51, Taylor test results were revised by Gertler, a staff member of the David Taylor Model Basin, Washington, D.C., and were published for B/T ratios of 2.25, 3.00, and 3.75 in a manner of plotting that was different from that used by Taylor. Using the frame offsets published by Gertler, the Shipbuilding Experiment Task of Berlin (Schiffbau-Versuchsanstalt Berlin) designed and tested a new series of 'Taylor Models' with a B/T ratio of 4.50. So as not to represent and apply these test results indepently of those published heretofore by Taylor and Gertler, the values of the Taylor series as corrected by Gertler were converted and added to the present paper in the same form of presentation as the SVA and results (SVA = Schiffbau-Versuchsanstalt Berlin).
