C. FY99. 3 program. 3 investment for all ship and submarine technology in the FY99 President’s Budget was about $100 million per year, which covers efforts in structures, internal machinery, topside signature reduction, and electromagnetic compatibility as well as hydromechanics. 3 effort averaged about $70 million per year, it does not seem adequate to conduct the type of technology demonstrations required for advanced platform concepts. Historically, it appears that the Navy has relied on acquisition program funding to effect large-scale technology demonstrations.
Effort on cavitation (category 5) is significantly larger. In categories 8 and 9, experimental techniques and bluff body hydrodynamics, which are more relevant to fundamental hydrodynamics, there is almost no Japanese research. S. activity in the more practical applications (categories 10 and up) is very much less than that of the Japanese. S. research has a more fundamental orientation while Japanese research is more practical. In computational fluid dynamics, for example, the United States has a greater emphasis on turbulence modeling and validation, while the Japanese have advanced further in the prediction of transverse and maneuvering forces, including the simulation, for example, of the response to rudder motions.
TECHNOLOGY ISSUES 17 with a free surface requires a detailed understanding of the vortex interactions at the free surface. Freesurface turbulence has features that are quite different from the turbulence in fully submerged flow because of the complex vortical interactions at the free surface. Aeration due to ship waves, wave breaking, and boundary layer entrainment are also not well understood. A complete knowledge of the source of bubbles in the wake of a ship is far from within our grasp. All these topics are of crucial interest to the stealth problem of surface vessels and submerged vessels running at shallow depths.
