DESIGN STUDY. VOLUME 1: HYDRODYNAMICS

Performance characteristics for the 80-knot version of the H.S. Denison are presented, as well as the hydrodynamic considerations which led to selection of final geometry for foils, struts, pod, and propeller. Comparative drags for the various geometries considered for each element were the basis for selection of the final configuration. The objectives of the model test program were: development of an optimum forward foil configuration which could make a measurement of cavity drag of blunt base pod designs for pusher and tractor propeller arrangements; measurement of the drag benefit to be gained by forced ventilation of pod configurations; measurement of cavity drag for blunt base strut configurations; and measurement of flap effectiveness. The theoretical basis for the evaluation of final configuration is established and various alternative geometries are considered. Also included are drag and thrust available curves for final craft configuration, final tail assembly configuration, and turning and hydrostatic characteristics of the craft.
