摘　　要：开式循环水下涡轮发动机动力系统本身的结构特点和工作条件决定了其特殊性。针对该系统进行数学建模是系统分析与设计的基础。基于系统物理机理分析和元件特性数据拟合相结合的方法,建立了完整的开式循环涡轮发动机动力推进系统的数学模型,该模型物理意义明确、构成简捷,精度较高,且便于参数调整和编程计算。该模型可应用于动力系统的性能评估和优化设计,同时由于该模型描述了系统的动态过程,是发动机控制系统设计的基础。An underwater turbine engine propulsion system has the particularities of its structure characteristic and working con- dition. Mathematical modeling of the engine propulsion system is necessary for the system analysis and system design. Combining the physical mechanism analysis and characteristic data fitting of primary components, a mathematical model of propulsion system of underwater turbine engine system with open loop cycle is built in this paper. The model has simple structure, clear physical meaning and high calculating precision. And its parameters adjustment, program coding and calculation are convenient. The model can be Used for performance evaluation and optimization design of the propulsion system. As the model describes the dynamic process of the system, it is the base of the design of the engine control system.
