XS Venture ascent autopilot 2

I’ve been working more on ascent autopilot, now it’s much more fuel efficient (altough it doesn’t follow the equations I wrote up before, it’s just a general autopilot), and smoother. There are some small issues to fix with smoothing, but it’s already ready for XS10 mission (which will test it in a real mission).

Here’s altitude, in feet:

And here’s graphs for engine fuel flows:

Here’s engine thrust and atmosphere density. Notice how engine thrust grows as density decreases (while aircraft speed increases):

After reaching certain maximum thrust output it starts to decay, because as we’re getting higher and higher, there is less and less oxygen for engines to work. Thrust and fuel flow are nearly similar, that’s just how X-Plane models the engines…
