theJesuit Posted March 17, 2019 Share Posted March 17, 2019 (edited) SIMPLEX Propulsion A mod that causes the atmospheric performance of all engines, and offers more natural fuel ratios. DOWNLOAD at Spacedock Requires: Module Manager (not included). Stock TechTree , TETRIX TechTree, or SIMPLEX TechTree Otherwise can be a standalone mod. Recommends: SIMPLEX Resources which now handles Fuel changes, and has options for PowderFuel ISRU and Nuclear Generators! Engines The performance of engines is nerfed in atmosphere only. Vacuum performance remains unchanged. It's purpose is an attempt at forcing the creation of two stage rockets to get into orbit around Kerbin, but retaining the STOCK feel of KSP once in vacuum. The performance at sea level on Kerbin is 70% of stock values. Vacuum performance is unaffected and so the performance improvement as you ascend is far greater rate than stock as it normalises. Engine Block Upgrades Engines that are designed to be used to launch rockets from Kerbin (Swivel, Reliant, Skipper etc.) have Part Upgrades to improve their atmospheric performance to 77% stock. Vacuum engines (such as Terrier or Poodle) do not have upgrades. These upgrades are available in upgrade nodes attached to the unlocking Tech Tree nodes where the engines are unlocked. Effectively costed 60% more science to increase power and efficiency by 10%. With JNSQ Engines will instead be nerfed to only 90% stock values at sea level. The upgrade will restore values to 100% stock. Other mods This is a global nerf so all mod engines are affected. NearFuture suite and Methalox CryoEngines are supported with upgrades. PALOX and PALOXUS These are new engines that run on a Powdered Aluminum and Oxygen suspension. Effectively a throttleable solid fuel engine that acts as a monopropellant engine. It is a late game vacuum only engine and works with SIMPLEX Resources in mind. PowderedFuel only requires NaturalOre to be produced. The engines look like they have been slapped together from Ore tanks and rockomax adapters (which is accurate). EMERGE This new engine is a beefed up Magnetic Plasma Ion Engine engine that requires a large amounts of EC. Again designed with SIMPLEX Resources in mind with its nuclear reactors. It is a late game vacuum only engine that is a little less powerful than the poodle, but will require either a large amount or energy storage, or a nuclear reactor to keep things running. THANKS AND ACKNOWLEDGMENT @Jimbodiah for the inspiration with the config he made for SSRSS. Check it out here: https://forum.kerbalspaceprogram.com/index.php?/topic/169534-12x-13x-simple-rss-patch/ @riocrokite for inspiration from SAFIRE and the persuasive work he did with ratios.

theJesuit Posted March 20, 2019 Author Share Posted March 20, 2019 Hi all, So we hit 52 downloads over night (gosh CKAN helps :). Thanks for giving it a go. I would be keen to know whether people are playing with other Simplex Mods or opt to not use the upgradesign or fuel ratio change. I've noticed an issue potentially with only simplex mods AND kerbalism and not having an ability to mine NaturalOre (to bake oxidiser). I'll look at this over the next few days. All other combinations look good though. So as I said, thanks for trying it out and feedback would be appreciated. I'm happy for a PM. Peace.

theJesuit Posted June 28, 2019 Author Share Posted June 28, 2019 Hi everyone, There will be an update at some point. I'm going to add an engine! Theis will be a aluminium/ox throttleable (sp?) Rocket engine. The idea being that it is to SolidFuel what LF/ox is to MonoPropellant. The idea being that it will be a low ISP med thrust vacuum only engine. Suitable for lifting off the Mün. With ISRU and SimplexResouces the fuel and Oxidizer will come from NaturalOre only. The concept comes form a NASA study into a rocket fuel using only Moon abundantin eras in the regolith. Hydrogen in a few small spots in polar craters doesn't qualify as abundant IMHO. No ETA yet. Peace Quote Link to comment Share on other sites More sharing options...

The use of the stock engine gave me the idea for the model. Peace. Quote Link to comment Share on other sites More sharing options...
theJesuit Posted September 17, 2021 Author Share Posted September 17, 2021 Hello everyone! I'm brushing off this mod again as I'm wanting to use it with the TETRIX TechTree and have it applicable to making JNSQ and other 2.5ish size systems harder TERIX is having a little 'under-the-hood' update in regards to the upgrade nodes, so this needed updating to remain compatible. Also, there have been stock engines which are renamed to "v2" so these need updating too. So the plans are: Have only 1 upgrade block rather than two The SAFIRE inspired change in Resources will be taken out as SIMPLEX Resources does this more comprehensively. With JNSQ upscaled systems, the overall abilities will be nerfed to 90% overall rather than the scaled atmospheric curve. The upgrade will restore it back to it's full 100% vanilla thrust and ISP requiring more science! With vanilla sized systems, the curve will be reduced to 70% at sea level but remain at 100% in vacuum. The upgrade will bring it back to 85% at sea level. The SIMPLEX TechTree will have its engine nerf removed (it had been for TETRIX anyway) This will apply to all Solid Fuel and LF only and LF/O rockets.

theJesuit Posted September 20, 2021 Author Share Posted September 20, 2021 Update as this is being worked on... Im wondering about adding more ignitions in upgrades when kerbalism is installed. Also... The idea for a late game engine that is analogous to an Aluminium Oxygen rocket. The new fuel will be Powdered Fuel. The engine will be called PALOX. ISRU will require only Natural Ore. So this will be a single source Ore fuel... hence late game. ISP will be 285 in vacuum. Not sure about thrust yet. Oh, and the engine will be throttleable.

Not sure about thrust yet. Oh, and the engine will be throttleable. Further update - Was getting really bad NREs? Nasty communications in the log with the initial redo of the upgrades. This is now sorted. Obviously atmospheric tuned rocket engines only get upgrades. Not ones designed for vacuum. Making History, Missing History, ReStock engines coded. Will look at NearFuture engines Cryoengines as well. New engine PALOX - Tier 7 engine. 2.5m New engine PALOXUS - Tier 8 engine. (bigger capacity, more thrust, 3.75m) The PALOX fuel will be PF or Powder Fuel. This will be a mono propellant similar to SolidFuel, but the engine will be vacuum and it will be throttleable. The density (mass?) of the PF will be the same as NaturalOre, or MetalOre in CRP. The ISRU (needs SIMPLEX Heavy ISRU, tier 8) recombines the constituent stuff of NaturalOre to be combustible. The fuel tanks will have low heat tolerance, as will the engine. Possibly will need active radiators to work. Peace. Quote Link to comment Share on other sites More sharing options...
theJesuit Posted September 25, 2021 Author Share Posted September 25, 2021 Working on balance for the Palox engines currently. Looking at making the Palox 2.5m one cpable for lifting a 36ton (orange tank) to Mun orbit from the surface interms of thrust fully loaded. May have enough delta vee to get to LKO with that orange tank too. I may make this closer to 36.5 ton to allow for probe sections, docking, power comms etc. The Paloxus 3.75m should be capable of lifting say 9ton total into orbit from Tylo's surface but no further. As the engines carry their own fuel, the Paloxus will need to reduce the amount of fuel to a bare minimum to get the TWR from Tylo enough. I haven't started on the heat balance yet so the masses I want to get off each body will have to cope with radiators and power too. Quote Link to comment Share on other sites More sharing options...

theJesuit Posted March 14, 2022 Author Share Posted March 14, 2022 Updated to 2.2 Added support for ReStock. Pretty. Quote Link to comment Share on other sites More sharing options...
theJesuit Posted November 17, 2022 Author Share Posted November 17, 2022 Updated to 2.3. Added a new engine - "EMERGE" Efficient Magneto Electric Rocket General Engine Basically a souped up ion engine for crewed craft. Quote Link to comment Share on other sites More sharing options...
