The Compressor Map Fitting Tool Smooth C

This program generates smooth compressor maps for use with gas turbine performance programs. The input can be calculated or measured data, map tables that you use with your preferred performance program, or calculated maps. It can also be a graphical presentation of the map. 

 

 

I begun the development of Smooth C in the early 1990's. The latest publicly available version Smooth C 9 has been released in August 2021 by GasTurb GmbH. The changes from the predecessor of this program are based on the ideas I presented at the ISABE conference 2019 in Canberra, Australia:

Generating Compressor Maps To Simulate Starting And Windmilling
Joachim Kurzke
ISABE-2019-24299

At the GPPS Conference October 17-19, 2023 in Hong Kong, China,  I presented another publication on the extension of compressor maps to pressure ratios less than one and very low speeds:

An Enhanced Compressor Map Extension Method Suited for Spool Speeds Down to 1%
Joachim Kurzke
Journal of the Global Power and Propulsion Society. 8: 215-226, 2024

The methods described in this paper have been developed with my experimental derivative of Smooth C 9.

At the GPPS Technical Conference 2026, September 9-11 in Montreal, Canada I have presented the paper GPPS-TC-2026-0083 entitled Generating Physically Accurate Compressor Maps which I wrote using my latest experimental derivative of Smooth C 9. 

Many maps created with Smooth C are available for download here.
