Gas turbine Simulation Program version 12 for Windows


Welcome to the Gas turbine Simulation Program GSP for Microsoft Windows. This GSP help manual (also available online through the GSP team website) includes information and guidelines for using the basic functionalities to build, adapt and run simulations of gas turbine models. For advanced users, detailed information on GSP modeling and simulation can be found in the GSP Technical Manual which is available to paid customers on request.


Royal Netherlands Aerospace Centre - NLR's Gas turbine Simulation Program (GSP) is a component-based gas turbine modeling environment. Both steady state and transient simulation of any gas turbine configuration can be performed by establishing a specific arrangement of engine component models. GSP is a powerful tool for performance prediction and both design point and off-design analysis and performance optimization. GSP is especially suitable for sensitivity analysis of variables such as: ambient (flight) conditions, installation losses, certain engine malfunctioning (including control system malfunctioning), component deterioration and exhaust gas emissions.


As of GSP version 11, a comprehensive case and configuration management functionality introduces features to improve usability, productivity, data integrity, and security. GSP contains session management, configuration and case management, process control, security features and improvements of the GUI. Note that due to the implementations of these functionalities restrictions apply to the setup of certain models. This implies that importing old version models (models saved in version 10 or lower) into the new project based structure may require some additional attention.


As of GSP version 12, a more powerful database storage solution is introduced. This SQL based storage solution offers comparison of various case results to facilitate much simpler analysis of case effects. Furthermore the output is better structured, grouped and colored per model component to find output parameters much more quickly. This version is also capable to adhere better to current standards as AS755 and ARP5571.


A great deal of GSP's power to rapidly analyse all sorts of engine performance aspects is due to the graphical user-interface, which parallels the consistent modular (i.e. "object oriented") structure of GSP. GSP's interface allows new users to perform easy "quick start" analysis tasks without the need to know all about the advanced features.


This ease-of-use is due to GSP being set up around three basic elements:

Project window                                

Component libraries as part of the main application window

Result tables and results graphs
