boil off problem solved

[5ardaukar]

For all those passionate players of RO/RSS who struggle with the boil off problem...

I tried many different ways to handle those liquid fuels, tried radiators, heat pumps etc...

As far as i can see... when you pass the 100x time warp (switching to analytic physics calculations) boil off happens...

I found a way. I tweaked the realtanktypes.cfg (realfuels) and the rftanks.cfg (procedural parts) to get a tank type which prevents boil off.

First it feels (and looks like) cheating I know... but considering that in the end every "feature" you need in space has to be paid with "weight" (insulation, radiator, electricity...),

i suggest you alter the basemass to stay in a realistic scenario....

I´m not the author of the mentioned mods, i just edited the cfgs.

Here is how.:

\gamedata\realfuels\resources\RealTankTypes.cfg

add..

//Ultra
TANK_DEFINITION
{
    name = Ultra
    highlyPressurized = False
    basemass = 0.000039 * volume
    outerInsulationFactor = 0.0005
    TANK
    {
        name = LqdOxygen
        mass = 0.0000112
        utilization = 1
        fillable = True
        amount = 0.0
        maxAmount = 0.0
        wallThickness = 0.0025
        wallConduction = 16
        insulationThickness = 0.0381
        insulationConduction = 0.014
        temperature = 400.15        
        note = (has insulation)
    }
    TANK
    {
        name = LqdHydrogen
        mass = 0.0000016
        utilization = 1
        fillable = True
        amount = 0.0
        maxAmount = 0.0
        temperature = 400.15
        wallThickness = 0.0025
        wallConduction = 205
        insulationThickness = 0.0381
        insulationConduction = 0.014
        note = (has insulation)
    }
    TANK
    {
        name = LqdAmmonia
        mass = 0.0000096
        utilization = 1
        fillable = True
        amount = 0.0
        maxAmount = 0.0
        temperature = 400.65
        wallThickness = 0.0025
        wallConduction = 205
        insulationThickness = 0.0381
        insulationConduction = 0.014
        note = (has insulation)
    }
    TANK
    {
        name = LqdMethane
        mass = 0.0000096
        utilization = 1
        fillable = True
        amount = 0.0
        maxAmount = 0.0
        temperature = 400.45
        wallThickness = 0.0025
        wallConduction = 205
        insulationThickness = 0.0381
        insulationConduction = 0.014
        note = (has insulation)
    }
}

 

\GameData\ProceduralParts\Parts\ZOtherMods\RFTank.cfg

add the bold line..

{
        name = ModuleFuelTanks

        volume = 1060
        utilizationTweakable = true
        type = Default
        typeAvailable = Default
        typeAvailable = Cryogenic
        typeAvailable = ServiceModule
        typeAvailable = Fuselage
        typeAvailable = Balloon
        typeAvailable = BalloonCryo
        typeAvailable = Structural
        typeAvailable = ElectricPropulsion
        typeAvailable = Ultra
    }
}

The temperature in the first cfg is the key...

What it does....:

Now it is possible to choose "ultra" as a procedural tank type which is capable

to store the configured fuels up to the given temperature in K.

 

 

Many thanx to all the modders out there who do a great job...
