I've given a tutorial about the basics of gas turbine performance at the Turbo Expo 2024 in London in June, and in September, I presented a paper at the ISABE conference in Toulouse:

Simulating starting and windmilling with a thermodynamic cycle program is a challenge. Compressor and turbine maps containing data for very low speeds are required for engine starting simulations, but usually not available. Methods for extenting maps had to be developed and were implemented into my experimental versions of the compressor and turbine map preparation programs Smooth C and Smooth T.

I presented three papers at GPPS conferences, which were subsequently published in the GPPS Journal.

I want to make it clear that I'm not happy with the way my ideas on engine starting and windmilling simulations were implemented in GasTurb 14. I've published my engine start and windmilling simulation methodology at the 2022 GPPS conference in Chania, Crete:
