About GasTurb

GasTurb GmbH
The company behind the GasTurb software package is based in Aachen, Germany, and develops and distributes the software from there. Through an offical cooperation with the RWTH Aachen university, GasTurb benefits from the impulses and foresight of research. Teaching and research at the university, in turn, benefit from direct access to the program.

The Original Author – Dr. Joachim Kurzke

Having worked on gas turbine performance prediction and engine test analysis since 1976, Dr. Kurzke is still involved in the development of GasTurb, both providing programming advice and sharing his extensive knowledge of gas turbine performance. He also offers consulting and teaching of gas turbine performance.

The History of GasTurb
The development of the program dates back to 1991 and continues to the present and future.


GasTurb 13 is released. Its new features comprise an improved map selection for more realistic off-design calculations and a clear geometric predesign, among others. The user interface has been carefully optimized and modernized.


The cooperation with ALR Aerospace begins. The Switzerland-based company is the developer of the Aircraft Performance Program APP, a widely-used PC-software for aircraft performance analysis. APP and GasTurb combined offer a broad scope of design and performance assessment capabilities, where both engine and aircraft can be considered in detail.


The support, maintenance and development of GasTurb has been transferred to the newly founded company GasTurb GmbH, which cooperates with the Institute of Jet Propulsion and Turbomachinery at RWTH Aachen University.


GasTurb 12 offers a clearer user interface, more detailed output (e.g. carpet plots) as well as further increased model fidelity (e.g. secondary air system, thrust management with EPR and N1 schedules).


The cooperation with Xeca Turbo Technologies begins. Customers now have a point of contact based in China.


GasTurb 11 is released, its major new feature being engine preliminary design including the cross section and disk design. The third level of detail “More” (...than performance) has been introduced to this end.


GasTurb 10 is more flexible and offers many new features without losing user friendliness. Results can be exported to MS Excel and colored contour plots have been introduced. New gas turbine configurations have been included (e.g. Turboshaft with Sequential Combustion, Turbofans with Ax-Rad HP Compressor) so that almost every commercially relevant gas turbine configuration can now be modelled.

Dr. Kurzke retires from MTU
which allows him to spend more time further developing the software as well as for consulting and teaching gas turbine performance.


GasTurb 9 introduces calculation modes with different levels of detail (Novice, Expert), an improved model fidelity and model based test analysis, besides many more features.

By now, the program is used by engineers and managers from industry and universities in more than 20 countries.


GasTurb 8 offers 15 engine configurations (e.g. intercooled, recuperated turboshafts, three-spool turbofan with afterburner), multiple different fuels, mission calculations.

GasTurb Details
allows for independent studies of engine components.

The software now has its online presence www.gasturb.de


GasTurb is registered as official Trademark.


The new version GasTurb 7 comes with a graphical user interface.


GasTurb 6 is released. It is for the first time presented at the Turbo Expo of the International Gas Turbine Institute IGTI: Advanced User-Friendly Gas Turbine Performance Calculations on a Personal Computer (Joachim Kurzke, ASME 95-GT-147)

The programs Smooth C
and Smooth T for component map generation are released.


The cooperation with Concepts NREC (back then: Concepts ETI) begins. Customers now have a point of contact based in the U.S.


GasTurb is publicly available (16bit DOS version).


Dr. Kurzke is granted the official approval of his secondary activity as software developer by MTU Aero Engines.


The development of GasTurb begins. Dr. Kurzke establishes the program in parallel to his main job as performance engineer with MTU Aero Engines, his primary aim being to make the program as user-friendly as possible.
