AbstractNot Available Research and development leading to drag reduction on fast moving ocean vehicles will be carried out in two ways: by reducing the wetted surface area and by controlling the boundary layer over the wetted part of the ship hull. The proposed concept of area reduction is through the use of underwater wings. Since wing cavitation is unavoidable for the given ship specifications, our principal efforts will be dedicated to reducing the cavitating wing drag, and a new inverse hydrodynamic problem to design a partially cavitating underwater wing will be solved. The inverse problem of friction reducton on the wetted parts of the ship (such as a fairing) will be solved by a combined selection of their shapes and of the methods of boundary layer suction or polymer ejection. A design of the future ship's architecture will be created on the basis of the solutions of the above inverse problems. Research method to estimate performance levels will be based on CFD, and the research during Phase I will be conducted for a pilot 2-D and for axis symmetrical problems. A 3-D model in greater detail will be provided in Phase II, as well as the experimental support of the research.
