Torpedo Turbine Control under Variable Conditions

As a torpedo runs at variable conditions, such as variable-speed or variable-depth, the change of turbine′s main running parameters will lead to the variation of other running parameters, resulting in low efficiency or even abnormal running of the turbine. To keep high efficiency and working stability under variable conditions, turbine power system must be regulated correspondingly. Therefore, a turbine power model is built in this paper, and the adjustable parameters for variable conditions in the model are analyzed. A control method of simultaneously regulating propellant flow and nozzle number is adopted, and the regulation of nozzle number is optimized. The feasibility of the method is validated by the simulation results.
