Report on Additional Testing at Salt Lake on a Government Owned 7-Ft Hydrosphere Conceptual Model,

Abstract

There are still several important questions to be answered before one can understand and characterize the Hydrosphere concept. One basic question is how to model and scale Hydrospheres, since it is still not clear what methods or parameters can be used for scaling performance to larger spheres. The general wave generating characteristics appear to be similar when one observes the wave generating performance of the 3', 7', and 10' Hydrospheres; however, the effect of loading had not been determined. It was decided that the next step in the Hydrosphere program should be a special set of tests designed to evaluate Hydrosphere performance under a different loading condition. This was not possible to accomplish within the present experimental project because the 7 ft Hydrosphere model was already operating at a 17% submergence level and it was not possible to lighten the model. It was felt that it should be possible, however, to operate and gather performance data on a body of water having a greater density. It is the results of this set of experiments, conducted at Salt Lake in Utah, that is the central theme of this report. Also included, however, are conclusions and recommendations for future work on this most unique and interesting amphibious watercraft concept.
