摘要

摘要: 鱼雷涡轮动力系统具有许多优于活塞动力系统的结构和工作特性，在现代鱼雷高速度和远航程的战术要求下，大型热动力鱼雷宜采用涡轮发动机作为推进主机。进行鱼雷涡轮动力装置数字仿真是设计涡轮机的重要步骤，为此，该文针对鱼雷涡轮机设计和研制的需求，采用理论分析、经验推导和实验研究相结合的方法建立了鱼雷开式循环部分进气纯冲动式复速级涡轮发动机设计工况及2 种常见变工况的数学模型，着重讨论了变工况过程涡轮机的调节控制方案，提出了简便易行的开关喷嘴控制方法，并对其进行了数字仿真研究。涡轮机内部结构及热力学参数仿真结果表明所建数学模型较为准确，变工况控制方法具有正确的理论依据，并易于工程实现。该文的数字仿真方法将为今后更深入的研究提供技术支持。

Abstract: 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.
