Research on environmental energy-driven intelligent unmanned underwater vehicles and their key technologies

For unmanned underwater vehicles (UUV) endurance is limited and it is difficult to accomplish long-endurance mission, the key technologies that drive UUV through the environmental energy have been studied. Environmental energy has the advantages of large amount of storage, renewable and clean, can be absorbed and transformed. It can be used to drive unmanned underwater vehicles. First of all, this paper analyzed the endurance and power demand of UUVs; the second, according to the type of environmental energy, the application of solar energy, ocean temperature difference energy and wave energy used in UUVs’ drive is described respectively. Mainly includes: natural characteristics and distribution of environmental energy; the feasibility of driving UUVs; The development of environmental driving UUVs and the research of its key technologies. In the end, the application prospect of environmental energy in unmanned underwater vehicle is stated.
