What is GSP ?

GSP is a generic modeling tool capable of modeling virtually any gas turbine engine configuration including (external) loads (like water breaks, pumps, generators, etc). GSP is primarily based on 0D-modelling (zero-D) of the thermodynamic cycle of the gas turbine. This implies that the flow properties are averaged over the flow cross section areas at the interface surfaces of the component models (inlet and the exit). GSP utilizes component model stacking to create the thermodynamic cycle of the engine of interest. Input of the model configuration is the cycle design, or any known reference point (or preferably several points) of a new engine. Information needed for the cycle configuration, eg. turbine and compressor maps, is readily available from the manufacturer or from the internet  (e.g. manufacturer fact sheets, ASME papers, etc.).

Besides being a performance prediction tool, GSP is especially suitable for parameter sensitivity analysis such as: ambient (flight) condition effects analysis, installation (losses) effects analysis, analysis of effects of certain engine malfunctioning (including control system malfunctioning) and component deterioration effects analysis. Input for the analysis is based on the model configuration (e.g. fuel flow can be specified to calculate the generated power, or when the fuel flow is set as a state variable the power can be specified to calculate the corresponding fuel flow). By running the simulation, output data set in the component property window will be displayed in a table, which can be visualized by a build-in graph tool. Data available includes the gas conditions (temperatures, pressures, mass flows, areas, speeds, etc) and the gas composition (gas species are available since GSP uses a full Thermo-chemical gas properties model). The simulation results can be exported to tab separated files, which can then be used for custom analysis (e.g. comparison of simulation data to running equipment measured data).
