CUVX Design – VT Team 2 Page 614.4 Power and PropulsionFigure 53. Negative Panel Adequacy for All Load CasesCUVX HI3 uses an Integrated Power System (IPS) for propulsion and ship service power. Power frompropulsion engines and ship service generators are shared between propulsion, aircraft operations, and ship serviceloads as required.4.4.1 ResistanceThe calculations for CUVX HI3’s resistance, speed, and power are shown in Appendix D.2. The Holtrop-Mennen Method with a WPTH worm-curve factor is used. The resulting resistance vs. speed curve is shown inFigure 54. The upper curve in Figure 54 represents the results of a model test performed at Virginia Tech for thisproject. Because of the small model size and crude test rig the Holtrop-Mennen results were used for the propulsioncalculations; not the model test results. The model test provided an excellent educational opportunity.Figure 54. Resistance vs. Speed Curve
