Question Custom Ship .Dll's Blocking Refueling?

[CTarana45]

Can a Custom .DLL file for an addon block the ability to refuel? I'm Trying gas up

Jon's Ragnar Anchorage Station and having no luck! :hello: I've tried FUEL 1 and PRPLEVEL 0:1.000! :thumbup:

Thanks!

Weird. Are you doing it with the editor?

With the scenario editor running the Propellent Button isn't usable!

Maybe it is because it has no propellant resource......

So how do we add that to the scenario?

Thanks, Urwumpe!

CAn you just click on that vessel in the editor and add fuel? I am getting that and I will check it out.

In that case, not at all. How would you store fuel without a tank? The station does not seem to be equipped for refueling.



And I think the add-ons have been closed source.

It's greyed out!! :lol:

I think Jon's is missing the "Aerodynamic stuff unless it's in the .dll file?

That does seem to be the case, no tank no gas! :thumbup:

And Jon's addons were closed source!

Thanks Urwumpe!

I added three lines to Jon' s Ragnar Anchorage Space Station and now it fuels up fine! I used the Scenario Editor twice to fill and drain the tanks! There are no engines defined to use the fuel! :lol:

What does isp stand for?

 

[Urwumpe]

What does isp stand for?

Specific impulse. That is the impulse that a rocket engine produces by burning one kg of fuel. Impulse is coarsely said, thrust force accumulated over time. Which is why the unit of specific impulse is Ns/kg, which magically reduces to m/s: The specific impulse is equal to the average exhaust velocity, the average speed at which the molecules of the exhaust leave the engine.



The higher the specific impulse, the less fuel must be burned per second to produce the same thrust. Chemical rocket engines of today reach between 800 and 4600 m/s, electrostatic engines up to 80000 m/s.



As you can expect because of the definition above: The speed of light is actually the limit. (But you would then need to calculate relativistic impulse, not simple Newtonian.)
