Abstract
The solar-powered autonomous underwater vehicle (AUV) may have unlimited autonomous capability in time and be an efficient tool to explore the ocean. The performances of solar powered AUV, evidently, depend on available solar energy. The low efficiency of industrially produced solar panels (10-16%) affords sufficient amounts of energy at low latitudes, but does not at high latitudes of about 60° and more. On the contrary, available wave energy distribution increases with latitude. A similar relation of solar and wave energies occurs regarding their seasonal variations. Hence, the combination of solar and wave energies promises more efficient use of the vehicle at all latitudes over the whole year. Converters of wave energy to electrical energy are usually cumbersome mechanical structures unsuitable for installation on an AUV.In this sense, it is more reasonable to use wave energy to aid the vehicle's motion. In this case a very fortunate situation occurs. It was shown that the best shape for a solar vehicle is a wing. At the same time it is possible to transform wave oscillations to forward movement using three wings, fixed on the hull of the vehicle. In this way, the demands of efficient solar-powered and wave-driven vehicles fully coincide. These relationships are considered in the paper and some resulting data are given.
