Website of the GasTurb Inventor
This software for calculating gas turbine performance has been well known in the public domain and acknowledged all over the world since 1995. In 2013 the ownership of GasTurb 12 and the accompanying software was transferred to the newly founded GasTurb GmbH in Aachen, Germany. I continued to support the further GasTurb development with my experience. Thanks to this fruitful cooperation, we were able to create an even more powerful release, named GasTurb 13. This software kept the established structure, technical standards, and engineering approach, while also introducing some enhancements to the easy-to-learn, user-friendly graphical interface.
In October 2019 GasTurb GmbH declared the end of collaboration.
Since retiring from MTU Aero Engines, I have been working as a freelancer in the field of gas turbine performance. My research interests include software with intuitive user interfaces, special graphical output formats, automatic identification of dubious inputs and results, robust algorithms, and exceptional simulation tasks. I disseminate the results of my research through publications, seminars, and workshops in collaboration with my consulting clients.
GasTurb is now a trademark of GasTurb GmbH, Aachen, Germany
A new tutorial dealing with gas turbine "Starting and Windmilling" is available for download free of charge from the Tutorials page.
The tutorial, "The Basics of Gas Turbine Off-Design Performance" is also available there. I presented it at the ASME Turbo Expo 2025 in Memphis, Tennessee, USA.
GasTurb 15 has been released. I don't have access to this program. Since 2021, I've also been denied access to GasTurb 14.
The book Propulsion and Power, 2nd edition, has been published on Springer Nature Link:

The GasTurb demo files and standard maps that I created serve the following purposes:
- First, they enable you to start the calculation process right away instead of having to begin from scratch.
- Second, they enable you to experiment with the program's features.
It was never my intention for the demo files to describe real gas turbines. Some demo files contain useful data, while others do not. This is especially true for off-design calculations with the standard maps. The geometry data is not always realistic either.
Performance models of real engines can be found here.
There are four Compressor Maps and two Turbine Maps available for you to download in GasTurb and NPSS format. These maps are extended down to 1% spool speed. They are suitable for engine start and windmilling simulation.
Five Performance Models of real engines are now available.
The history of GasTurb began in the early 1990s. I presented the first paper about it at the International Gas Turbine and Aeroengine Congress and Exposition, Houston, Texas, back in June 1995.
