GasTurb simulates the most important gas turbine configurations used for propulsion or for power generation. Virtually all gas turbine performance simulation problems can be solved with GasTurb, for example:.Use the program for teaching gas turbine thermodynamics. Employ instead of inaccurate sketches exact enthalpy- entropy diagrams that are to scale, for example. The graphical output of parametric studies can show true numbers about how the thermal efficiency depends on pressure ratio and burner exit temperature.

The assumption of constant isentropic exponent is not necessary - with GasTurb it is no burden working always with the true gas properties. Thus not only the tendencies shown in the lessons are correct, even the absolute numbers are valid.The program is ideal for self study by students, for diploma and even for thesis work. Many scientific publications presented at international conferences like the yearly Turbo Expo (organized by the International Gas Turbine Institute IGTI) or the International Symposium of Air Breathing Engines ISABE have been prepared with GasTurb.Creating a precise simulation of a real engine based on usually limited information is not difficult if only a single operating point is considered. Extending the single point simulation to off- design conditions is supported by several program features dedicated especially to this task. Component maps can be adapted in such a way that the off- design model is in line with data one might have got either from measurements or from some other source.GasTurb offers help for engineers who must examine data measured on a gas turbine in service or on a test bed. If the behavior of an engine is not as expected then “What if.” studies can help finding out the reason for the extraordinary behavior.Go through the various pages of this site to learn more about some further simulation problems GasTurb can help to solve.

About GSPThe Gas turbine Simulation Program GSP, a component based modelling environment, is NLR’s primary tool for gas turbine engine performance analysis. GSP's flexible object-oriented architecture allows steady-state and transient simulation of any gas turbine configuration using a user-friendly drag & drop interface with on-line help running under MS-Windows. Gas turbine configurations are simulated by establishing a specific arrangement of engine component models in a model window (view an example model window).What is GSPGSP is a generic modelling tool capable of modelling 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).GSP historyThe development of GSP started at the Delft Technical University (TUD, Aerospace dept.) in 1986. At TUD, NASA's DYNGEN (NASA TN D-7901, 1975) program was used for jet- and turbofan engine simulation. However, DYNGEN appeared to have many problems with numerical stability and had a poor user interface.

As a consequence, GSP was developed, inheriting features from DYNGEN. Significant deficiencies of DYNGEN were fixed in GSP; especially the stability, the speed of the numerical iteration processes and the user interface were improved. It appeared that an additional amount of improvements, adjustments and extensions to the GSP program were necessary before useful simulation of a generic jet engine was possible. Development continued at NLR, where GSP has been converted first to FORTRAN77 and later when desktop computers gained computational power for acceptable prices to Borland® Delphi(TM).

Delphi allows rapid adaptation due to the use of object orientation, offering excellent means to maintain and extend the program. DYNGEN (1975). unstable. slow. poor user interface. GSP in FORTRAN77 (1986). thesis of W.
