Information Changelog Stats

This part pack is designed to provide some new nuclear thermal rockets for your spaceship-building pleasure. There are four new engines, two in the 2.5m size class and two in the 1.25m size class. They are fuelled with LiquidHydrogen, and in some cases can use Oxidizer to boost their thrust at the cost of specific impulse. Liquid Hydrogen is less dense than liquid fuel, so for the same Delta-V, you will need more tank volume. 

To store your liquid hydrogen fuels, I've provided ModuleManager/InterstellarFuelSwitch configs that allow you to change the contents of stock tanks between LF/O, LH2/O, LF, O and LH2. These should work with most mod tanks, but no promises. However, Liquid Hydrogen is very temperamental and without the proper storage it will slowly evaporate ("boil off"). Therefore, I provide special cryogenic tanks bundled with the mod, that use a small amount of Electric Charge to stop the evaporation.

This mod is designed to synergize well with Cryogenic Engines 0.2.0+, and with the various Near Future Technologies mods I make.
