Abstract : The thesis involves an investigation of the hydrodynamic forces and moments on a submerged body of revolution, resulting from the addition of an asymmetric fairwater, and hull-control surfaces, and the results of their interactions. This investigation involved both experimental and numerical models. Experimental tests were performed in the M.I.T. variable pressure water tunnel on a fairwater model, with independently-controlled hydroplanes, and on a submersible model, whose configuration was systematically altered by the addition of a fairwater and control surfaces. Graphical results for both of these models are presented. Flow visualization tests were also performed. (Modified author abstract)
