Resistance scaling and predictions of SLICE hulls from model tests
Stevens, Henry William.

This thesis evaluates several techniques for extrapolating full scale resistance of SLICE hulls from model test data. Using Froude's hypothesis, the ITTC and Hughes methods are employed to analyze single length and fragmented wetted surface area procedures. Finally, a hybrid procedure analyzing the struts as wing shapes and the pods as full hull forms is endeavored. It is shown that the classical Froude method severely overestimates the resistance of a SLICE hull. All approaches predict higher total resistances than Lockheed's own analysis, which is based on a variation of Hughes method. This thesis predicts that speeds of greater than thirty knots are achievable with the primary engine choice.
