Hey, I'm new to this, is there a way to directly get the Fuel consumption rate that you can find in brackets in you resource overview? Currently I'm doing it like this: set Y1 to ship:liquidfuel. wait 10. set Y2 to ship:liquidfuel. set cps to ((y1-y2)/10). print cps. The Liquidfuel is measured every 10 sec and the consumption rate is the difference divided by 10. The Problem is, ship:liquidfuel always gives a whole number so if your fuel consumption rate is e.g. 0.04, the displayed amount of liquid fuel doesn't change within 10 sec. Of course I could do even larger intervals between the measurements but I don't really want to do that. Is there a way to get the fuel consumption rate directly? I couldn't find anything in the documentation.. Thanks!

Thanks for the clue! Yes, I assumed that the function would depend on some constants like mass, air drag and engines that are individual for the vessel, we just have to figure out how these constants relate to altitude.. Theoretically this should be possible, shouldn't it? Well I want a function to describe one of those graphs, "Fuel flow relative to altitude", and those are empirical measurements, not the theoretical results of a function..

Jet Engines. In my specific case I'm using the Basic Jet Engine. I want to compare the fuel efficiency of a plane with different numbers of Engines in "Meters per Fuel Unit" which is Ground Speed (m/s) divided by Fuel Rate (Units/s). I already made some manual measurements but I'm curious if this can be expressed as a function of the altitude. These are my measurements: "MFU" is Meters per Unit of Fuel (Ground Speed divided by Fuel Rate)

I know, I should say the fuel consumption rate if we assume the weight is constant or the initial fuel consumption rate at 100% Fuel. I want to know what the initial fuel consumption rate and Ground speed is when I fly up to Altitude X with and then turn off infinite fuel

Hey! Assuming I'm flying a plane in KSP with a constant weight horizontally at 100% thrust, is it possible to plot the ground speed or the fuel consumption rate (in units per second) as a function of the altitude? I want to use Ground Speed because the "Surface Speed" is measured at the altitude of the aircraft and because of the curvature of Kerbin it is higher than actual Ground Speed. At 10,000m up the difference is about 1.6%. For a more accurate number we need to convert "Surface Speed" to the actual Ground Speed, I came up with this equation: VGround = ( V"Surface" * rKerbin ) / ( rKerbin + LAltitude ) The equation for fuel consumption in tonnes/s is this: Fuel Rate (t/s) = Thrust / ( g * Isp ) Fuel Units are measured in liters and the density is 5 kg/l so we get this Formula for Units/s: Fuel Rate (Units/s) = ( Thrust / ( g * Isp ) ) * ( 1000 / 5 ) or Fuel Rate (Units/s) = ( Thrust / ( g * Isp ) ) * 200 That's as far as my knowledge goes, I hope you can help! Thanks!
