A mod pack for Kerbal Space Program, focused on delivering a new set of engines for spacecraft.
This mod features several new engines that use two new resources, Liquid Hydrogen and Liquid Methane. These fuels provide advanatages and disadvantages compared to stock Liquid Fuel, having different efficiencies, thrust ranges and storage volumes.
Liquid Hydrogen engines are divided into two categories:
- Sustainer Engines: Five sustainer style engines in the 0.625m, 1.25m, 1.875m, 2.5m and 3.75m size classes. Sustainers perform well at most altitudes but are less thrusty than LF/O engines, so may require boosters
- Vacuum Engines: Four vacuum-optimized engines in the 1.25m, 1.875m, 2.5m and 3.75m size classes. These engines work best outside of at atmosphere and don't produce much thrust.
Liquid Methane engines are divided into two categories:
- Booster Engines: Five booster style engines in the 0.625m, 1.25m, 1.875m, 2.5m and 3.75m size classes. Liquid Methane boosters are quite powerful and provide similar thrust to their LFO counterparts, but are less efficient than LH2 versions.
- Vacuum Engines: Five vacuum-optimized engines in the 0.625, 1.25m, 1.875m, 2.5m and 3.75m size classes. These engines work best outside of at atmosphere and don't produce much thrust, but tend to be more powerful than LH2 equivalents
In addition, my CryoTanks mod is also bundled to provide fuel handling for Liquid Hydrogen and Methane.
- Fuel Switching: A set of patches provide fuel-switching features for most basic LF and LF/O tanks
- Orbital Fuel Tanks: A set of fuel tanks specially designed to contain cryogenic fuels
For more information, check out the CryoTanks readme.
These components are required for the mod to function and are bundled as part of any download:
- ModuleManager (4.2.1)
- B9PartSwitch (2.18.0)
- Community Resource Pack (1.4.2)
- CryoTanks (1.6.3)
- DynamicBatteryStorage (2.2.5)
- DeployableEngines (1.3.1)
To install, place the GameData folder inside your Kerbal Space Program folder. If asked to overwrite files, please do so.
NOTE: Do NOT rename or move folders within the GameData folder - this mod uses absolute paths to assets and will break if this happens.
Some extra patches are bundled that you can use to tweak your installation. To install them, drop the correct folder from the Extras folder into your KSP GameData Folder
- CryoEnginesLFO: Converts engines to use LF/O instead of LH2/O at the cost of some Isp
- CryoEnginesNFAero: Converts some appropriate engines to use LH2/O or LH instead of LF/O with some Isp and thrust tweaks
- CryoEnginesRestock: Converts some appropriate engines to use LH2/O instead of LF/O with some Isp and thrust tweaks
This mod includes compatibility patches for the following mods:
- KSP-AVC: Provides version checking
- Community Tech Tree: Provides an expanded, community-sourced technology tree for modders to use
I certainly accept pull requests. Please target all such things to the dev branch though!
