Ziff Posted September 17, 2012 Share Posted September 17, 2012 That looks a lot like the v0.16 fuel bug. Are you running the fuel bug fix?That's because it is the fuel bug. Notice how Delta-V per kg of fuel used increases dramatically as throttle is lowered? Yeah. Not to mention that Isp is 3490 at 10% throttle. Isp should not change with throttle adjustment.

Nadrek Posted September 18, 2012 Share Posted September 18, 2012 Correct; that is data that shows at least one fuel bug.After 0.17 comes out, anyone who wants can install Mechjeb [for long enough] to run it, and see if there are other, less blatantly obvious fuel bugs affecting particular rockets. Regrettably, my current technique is very simple, and only works in space.You can do it yourself, if you wish:Circularize your orbit.Bring your rocket to x% thrust; give it some time to be there.Deactivate staging.Measure the amount of orbital velocity change and starting and ending mass over an amount of time.Do math.
