Torpedo Turbine Power System Simulation

More and more higher performance of thermodynamic propulsion system of torpedo is required to adapt to the modern sea tight. So the research of efficient thermodynamic propulsion system becomes urgent in the research and development of torpedo. Because of its security and economical use. digital simulation technology is widely being used in all kind of engineering fields. The use of digital simulation technology in thermodynamic torpedo provides a new way to the design and development of thermodynamic propulsion system.In the paper, the structure type of torpedo turbine engine and the three-speed system states of work gas were researched. The work process of torpedo turbine engine was analyzed. Based on the theory of engineering thermodynamics, inner parameter and thermodynamic calculation mathematic model of turbine engine were established. The thermodynamic calculation and the structure design of torpedo turbine engine were completed at the same time. In addition, the interaction of all parameters was analyzed. The non-design condition parameters of torpedo turbine engine were also analyzed.It was established that the dynamic mathematic models of typical work state: steady states, process of changing speed of the open-loop propulsion system in the same depth, process of changing depth in the same speed. Four steps Runge-Kutta was adopted in the simulation of the process mentioned above, satisfying results gained. After simulator program with friendly interface programmed using object oriented language, Delphi 6.0, the simulator process was analyzed with MATLAB 6.0. Simulator curves and programs will work well in the design of torpedo turbine propulsion system and have important reference value in the design and simulation of whole torpedo.
