SSG(X) Design – VT Team 3 Page 58 All of these volumes were used in calculating the submerged LCB of the submarine. For the LCB calculation all centers of buoyancy were taken with respect to the forward most point of the envelope hull. Table 37 summarizes the LCB calculation of SSG(X).

SSG(X) Design – VT Team 3 Page 59 4.3.3 Weights Ship weights are grouped by SWBS. The components list was obtained from the Model Center optimization. The weight for each component was compiled into an Excel spreadsheet. In addition to the weights, their centers of gravity (vertical and longitudinal) were entered. These centers of gravity were estimated using the ship’s arrangements. The weights and centers of gravity (CG) were used to find the lightship load and CG of the submarine. To make sure that the submarine was balanced, the longitudinal CG (LCG) needed to be as close to the longitudinal center of buoyancy (LCB) as possible. In order to facilitate this need, the centers of all of the components were taken with reference to the LCB of the submarine. The LCB of the ship was taken to be at the volumetric center of the buoyant volumes of the submarine. The LCB turned out to be 119 ft. from the bow. A summary of the weights by SWBS code and the lightships weight are listed in table (insert ref). The complete weights spreadsheet is provided in the appendix (whatever). Table 38 - Lightship Weight Summary SWBS Group Weight (lton) VCG (ft) LCG (ft) 100 1220.51 -0.29 3.66 200 334.58 -2.55 -50.05 300 44.59 -2.40 -33.40 400 159.74 1.52 76.46 500 178.12 1.09 -0.62 600 57.65 0.73 9.52 700 49.89 0.55 32.03 8 (Lead) 315.00 -15.00 26.98 Total (LS+8) 2360.08 -2.34 3.80 4.3.4 Load Conditions The arrangements drawings, weights spreadsheet, and the variable loads are used in creating the extreme loading conditions in the different water densities that the submarine will encounter. The loading conditions used are the Normal Condition, Light #1, Heavy #1, Heavy #2 (mines), Heavy Forward #1, Heavy Forward #2, and Heavy Aft. Table 39 illustrates each of the loading conditions and the water density used for each loading condition. Once the loading conditions were positioned on the plot with the polygon, the next task was to get all of the points inside of the polygon. To do this, ballast tanks were changed, components were moved, and lead was added and taken away. Figure 92 shows the final equilibrium polygon with all of the loading conditions inside of it.
