You are on the website of Dr. Joachim Kurzke, the inventor of GasTurb. 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 then, I have continued to work on the topic of gas turbine performance. My experimental performance software ExPP23 incorporates a number of new simulation algorithms, a user interface inspired by Microsoft Office, a method for identifying questionable results in the graphical output, and a number of other features that facilitate the learning and use of the program.

What’s New?

  • The second issue of "Propulsion and Power" is on its way. The manuscript has just been submitted to Springer Nature, and the book is expected to be published later this year.
  • I got an award:


At the Turbo Expo 2024 I gave a tutorial on the basics of gas turbine and aircraft engine performance. You can download an enhanced version of the material I presented.
