Warning: this is very out-of-date and was essentially my first ever program that I wrote back in (I think) 2014 or 2013. The "code" is beyond terrible, but it has sentimental value 🙂
A program to calculate the parameters of a turbofan: Based on the book Aircraft Engine Design by John Mattingly I developed a standalone program with GUI that calculates the parameters of bypass dual-spool turbojet engines with or without an afterburner.
Here I present a github repository with my software, which also contains a manual describing the usage of this application (only in polish).
Important: please note, that this program requires Matlab Compiler Runtime to run.
