Hello, I am working on a senior design project for school which is the development of an air and space thermal rocket engine with turbo jet. The Nuclear Turbojet in KSP Interstellar has the same capabilities that I'm looking for and I have already changed the way it looks. Right now, I'm trying to change the cfg file so that it's fuel consumption rate matches that of my calculations, however, I cannot seem to find where to change this. I am able to get the desired thrust and changing the amount of fuel consumption is the final step in what I need to do to get this to work properly.
The challenge with this is that this engine uses two types of fuel: air and liquid fuel. So it is difficult to isolate the parameters that affect only the air operation and only the rocket operation.
The cfg code for this engine is shown below. Any help will be greatly appreciated.
Thank you.
