Abstract
This memorandum outlines a method for estimating the near-bottom loads on a submarine submerged in deep water and for the related problem of predicting submarine squat in deep or shallow water. The method is fully three-dimensional, but has some limitations associated with potential flow and linearization of the free surface. The chief difficulty for this study was the dearth of suitable data available for validation. Nevertheless, the results are encouraging. Overall, it appears that the sinkage component of squat is predicted with greater accuracy than is trim. Further work should include the acquisition of more, reliable, model data and the investigation of scale effects.
