Rocketry info

I've added my notes on decompiled rocket engine code on User:RA2lover/Sandbox/Thermodynamics_machinery_notes. I refuse to post on reddit since getting disgusted by its API changes and i'm not on discord since getting banned from it, but still occasionally check /r/stationeers. saw your post there and figured maybe some info may be useful.

Is the PFGE max thrust figure obtained from running both inputs with premixed 60.7MPa fuel at 196 K? You can add up to 0.05 mol/L of frozen gases or liquids to a pipe network before it starts taking damage and i wonder if adding ~0.134% of frozen liquid nitrous oxide is enough to get another 100-200N of thrust.

Evaporation coefficients

Saw your reddit post asking for these so i went looking for them. The game does, in fact, use exponential curves for these and they can be found in the MoleHelper class as EvaporationCoefficientA And EvaporationCoefficientB.

The evaporation pressure for a given temperature and liquid is EvaporationCoefficientA * Temperature^EvaporationCoefficientB
The evaporation temperature for a given pressure and liquid is ( Pressure / EvaporationCoefficientA )^( 1 / EvaporationCoefficientB )

Here are the coefficients for each liquid:

 Liquid              A                    B
 Oxygen              2.6854996004e-11     6.49214937325

Steam uses the same coefficients as water. RA2lover (talk) 14:39, 22 January 2026 (CST)
