US Naval Academy Presenters
Speaker: William R. Garland
Abstract: Stepped Planing Hull Investigation
Planing hulls were developed to overcome the inherent disadvantages associated wither operating displacement hulls at high speeds, but their form has not yet been perfected. Proportionally, only a relatively small amount of a planing hull contributes to lift, while the majority of the afterbody simply adds to wetted area and frictional resistance. If flow separation can be achieved from a step aptly located and properly sized on the hull bottom and adequate ventilation occurs aft of the step, then resistances and power requirements will be reduced substantially at high speeds.

Speaker: Andrea M Lazzaro
Abstract: Material Properties of Functionally Graded Metal Matrix Composites
Tests were performed on a functionally graded metal matrix composite (MMC), in particular a copper-tungsten MMC, in order to determine basic properties such as electrical resistivity, hardness, density, and particle distribution of the constituents within the MMC. The tested material is being evaluated in terms of its ability to withstand the strain rates and temperatures of an electromagnetic launcher (EML).

Testing techniques are discussed and recommendations for modeling expected properties based on the rule of mixtures is presented.

Speaker: Jason C. Murphy
Abstract: A Novel Approach to Turbulence Stimulation for Ship-Model Testing
This project examined the use of turbulence stimulation to create a "similar" boundary layer between a ship and its model. Data collected from hot film sensors were used to assess the flow around both a flat plate and a 2-D model in order to evaluate the effect of turbulence stimulators.
