GSP applies tabular component characteristic maps to determine the relations among up to 5 component operating point parameters. The maps are stored in separate files, or alternatively can be stored embedded, and are compatible with the MTU / GasTurb [1] format. Map files are installed upon installation of GSP in the GSP sample models folder.
Note that in the map formats described hereafter, text with a blue font is information and therefore not part of the actual map file.
The different map formats that are used in GSP are briefly described hereafter. The header refers to the application of the map, while in brackets the amount of input and output parameters are given. A compressor map is defined by 2 input parameters (Beta parameter and Speed parameter), to find Efficiency, Pressure Ratio and Corrected Mass Flow, hence 2 in 3 out.
Example maps can be found in the default sample projects folder or embedded in the supplied sample project files.
