An overview on the test results of High speed semi-submersible vehicle with wings

In this article, we have studied the High speed semi-submersible vehicle with wings using the test results of some specific models and analyzed the hydrodynamic parameters and wave making resistance. The vehicle is called HSV (High speed Semi-submersible Vehicle with wings) here, is consisting of a main hull, main wings and a strut. The HSV floats at a certain draft like a conventional ship while it is still, and it submerged when it moves forward due to a downward lift force induced by the main wings. The lift force by the main wings at the various submergence depths remarkably reduces the wave making resistance. The wings contribute to reduce the wave making resistance by making the hall submerged and also through the cancellation of the waves generated by the hull. The hydrodynamics viewpoint, the estimation of the effective horsepower using the empirical methods and available equations for these vehicles is still not actually acceptable. However, it can be expected that the wave making resistance is still more reduced by the modification of the hull and wing forms. On the other hand, a half the estimated horsepower was frictional resistance component and an innovative means must be necessary for the frictional resistance to be reduced.
