STATIC CONTROL OF DRAG-REDUCING AIR CAVITIES WITH VARIABLE CAVITATOR SHAPE - Copy

Conserving energy and reducing environmental impacts are two major goals of modern engineering developments, including ship design. The world fleet of marine vessels is one of the main consumers of fossil fuels and contributors to pollutant emission. Significantly reducing hydrodynamic resistance of ships can decrease energy consumption and pollution. However, traditional ship hulls are already optimized to the point where small modifications of hull forms do not produce a significant benefit. Advanced marine vehicles with radically different hulls (such as hydrofoils, air cushion vehicles, 
and multi-hulls) have found
