Power performance prediction of large displacement UUV with solid oxy-hydrogen energy propulsion

To study power performance of large displacement UUV with solid oxy-hydrogen energy propulsion, a design solution of solid oxy-hydrogen power system is finished. Firstly, by using GA algorithm, structural optimization study for stream turbine is finished with maximizing inner efficiency in design condition, which matches the propulsion power requirements of the large displacement UUV. Secondly, the method of underwater rapid and controllable hydrogen and oxygen generation is designed, and whose mass flow is obtained according to the principle of minimum Gibbs free energy and Hess law. At last, calculations of cruising ability for large displacement UUV with solid oxyhydrogen energy propulsion is finished. Results show that solid oxy-hydrogen energy has doubly increased cruising ability and long-distance distribution ability for large displacement UUV. The scheme in this paper provides a new solution for the remote propulsion of large displacement UUV.
