How to keep the LV-N from losing thrust? [Mistake. Ignore]

[CaptainKipard]

Why is this happening? How to stop it from happening?

Right now my kOS node execution script is timed, and it worked fine so far but with decreasing thrust, the burn always falls short.

Ignore this. It's my script doing that.

The LV-N doesn't just loose thrust at random so I can't tell what your problem might be. Is your script toying with the throttle at all?

Engines don't just randomly lose thrust. You must have done something to make this happen.

You can change max thrust with tweakables, so that might be it

It doesn't look random. When I'm throttled up it slowly goes down from 60kN to about 58.7 in the span of several seconds. Is there a mod that does this? I have a lot installed, but I haven't modified anything myself. I think I heard Scott Manley in one of his latest videos mention that the LV-N does this.

Odd, I can't say I've heard of this happening until now. But if it's something predictable and happening every time, maybe you'll need to increase your burn time until the root of the issue is determined.

Damnit I'm an idiot. Of course it's my script! It's designed to keep acceleration constant, so it throttles down based on expended mass. Ignore this.

[FenrirWolf]

Some part of me thought that might be what's happening, since by default acceleration should be increasing during a burn instead of holding constant. Good to see you found what was wrong though!

I gues that's a compliment to your scripting talents, if your script does exactly what it's supposed to do, while you didn't even concider it

[CaptainKipard]

Oh, you.

This is off topic but just a head-up to anyone using kOS. Very long LV-N burns like the one required for asteroid rendezvous don't work well when timed.
