Digital Simulation of Torpedo Turbine

Torpedo turbine engine has higher performance than piston engine in many aspects. Since higher speed and range is needed for torpedo to play it’ s role in the future combat , turbine engine will be a better choice for heavyweight thermal power torpedo.Digital simulation is an important step for torpedo turbine engine design. This paper investigates the modeling and simulation of unclosed cycle and partial flow two-stage impulse torpedo turbine in design condition and two non-design conditions. The control modes of turbine in non-design conditions are discussed. A simple control method for adjusting the switch nozzle during transition processes is presented. The simulation results show the reliability of the models. The proposed method can be used for designing , validating and optimizing torpedo turbine.
