Smooth C generates smooth compressor maps for use with gas turbine performance programs.

I begun the development of Smooth C in the early 1990's. The latest publicly available version 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

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%

The input to Smooth C can be calculated or measured data, map tables you use with your favourite performance program, or a figure like this:

This is what you will get from me:
