RESISTANCE TESTS OF A SYSTEMATIC SERIES OF PARTIALLY AIR SUPPORTED VEHICLES

Abstract

Four partial air support (Hydrokeel) vehicles of different length- beam ratio have been tested for resistance at a number of loads, speeds, and trim conditions. All data are presented in nondimensional form for use in comparing hull forms. The tests showed that the use of an air support system significantly improves the performance of this configuration. Lift-drag ratios greater than ten were obtained for a wide range of conditions. Wetted boundaries were not discernible, nor could planing lift be deduced, due to the complexity of the flow.
