某艇用三轴燃气轮机性能仿真研究

Performance simulation of X-type naval ship′s triple-shaft gas turbine

针对目标燃气轮机实际运行特性参数难以获取的问题,首先在应用相似理论对参考燃气轮机的特性参数进行变换和修正的基础上得到了目标燃气轮机的近似特性数据;其中,采用容积惯性法对目标燃气轮机各主要部件进行了动态仿真,得到了该型机主要性能参数的变化规律,所得结果与厂家提供的数据一致。

As the objective gas turbine＇s real running characteristic parameters are difficult to obtain, the objective gas turbine＇s characteristic data is firstly obtained by transforming and adjusting the characteristic data of the reference gas turbine based on the similarity theory. Then, a dynamic performance simulation of each main component of the objective gas turbine is performed by using the volume inertia method. The change law of the main performance parameters of the objective gas turbine is obtained. The results agree with the data provided by the manufacture.
