摘　　要：应用Matlab的GUI平台开发了基于离散数据的固冲发动机性能分析软件PERFORMANCE SHOW,它以发动机性能计算获得的离散数据为输入,采用多维插值、多项式拟合、多项式求根、等值面计算、逻辑运算等方法,能够获得描述发动机工作特性的曲线、曲面和实体,从而可对发动机性能进行多维度深入分析。PERFORMANCE SHOW软件界面友好,使用简便,适合于各类冲压发动机的性能分析。In this paper,VFDR performance analysis software（ named PERFORMANCE SHOW） was developed based on Matlab GUI.Applying discrete data（calculated by using performance model） as input,VFDR performance characteristics curves,surfaces or volumetric data can all be obtained.The main methods including multidimensional interpolation,polynomial fitting,polynomial root,isosurface calculation and logical operation were presented.The software has fairly friendly interface,which provides the universal tools for ramjet performance analysis.
