[v0.1] MOSOI Ind. MicroFuels (Half-RF, half-stock)

[Niemand303]

Your idea is very nice, but...

1) Stock "Oxidizer" is not LOX.

Why?

Let's just sum up some known facts.

It is used along with stock "Liquid fuel" which is almost undoubtely a replica of RT-1 (Kerosene). KeroLOX is OK, but is not the only available Kerosene-based mix.

It is available at the lowest tech level (Kerbin 1940-s or 1950-s). LOX was used at earliest german rockets, but there were lots of tries to replace it with something less cryogenic and more manageable at 50-s. Nitric acid, dinitrogen tetroxide, dioxygen difluoride, etc.

It lets multiple ignitions on ANY engines - even the most primitive ones. IIRC KeroLOX requires additional ignition systems to do that.

It can stay in tanks for YEARS - even under the burning rays of Kerbol at Moho orbit. LOX is cryogenic and thus not very storageable.

Not a single LifeSupport mod treat it as a source of breathable oxygen. So it's NOT an oxygen, right? At least not a pure oxygen...

Summing up the facts above, we can conclude that "Oxidizer" is some kind of hypergolic oxidizer allowing self-ignition rather then LOX. Most probably it's one of many HNO3/N2O4 mixes that were used IRL along with kerosene.

Hydrazine/NTO looks more realistic LFO decifer then Kerosene/NTO, especially in terms of self-ignition. But since both are viable and LF is treated as Kerosene...

On the other hand - you need to make MM configs anyway...

2) Treating monopropellant as hydrazine is plausible (especially concidering N2H4 being the most common monopropellant). But hypergolic N2H4/N2O4 (hydrazine/tetroxide) mix in this case will look like "Monopropellant/Oxidizer" and that's just ODD. Maybe an MM patch replacing all parts "Monoropellant" with "Hydrazine"?

3) Methane is a must for any ISRU mods support. It's a byproduct of Sabatier process (both life support oxygen regeneration and ISRU fuel production) and also was and is concidered as an alternative fuel for real nuclear drive projects, providing better thrust at cost of lower ISP (comparing to liquid hydrogen) while not being as highly cryogenic.

So... we should have such fuels and mixes:

Kerosene - for jets and propellers

Kerosene/NTO (skipping the nitric acid part) - robust early/lowtech mix, not messing with cryogenics

Hydrazine/NTO - effective hypergolic mix for both engines and RCS

Hydrazine - monopropellant for RCS and smallest probe engines

Kerosene/LOX - cheap and dense lower stage mix, more efficient than Kerosene/NTO, less expensive and poisonous then Hydrazine/NTO, but needing cryogenic tanks for long term missions

H2/LOX - highly cryogenic mix - either use it as low stage or face severe boiloff

CH4/LOX - not-so-highly cryogenic mix - mostly for ISRU refuelling capability and to utilize LS byproduct

H2 - highly cryogenic nuclear propellant severe boiloff!)

CH4 not-so-highly cryogenic nuclear propellant (less boiloff, more thrust, less ISP)

Xenon - ionic propellant

P.S. CH4/NTO mix is possible but not viable.

1) I won't repeat twice the same arguments, but leave a link to a post with the reasons why it would be better to make stock LF/OX as Kerolox: http://forum.kerbalspaceprogram.com/threads/107735-WIP-NearFuels-%28Design-Stage%29?p=1694443&viewfull=1#post1694443

2) I haven't planned to make a monoprop/oxidizer mixture, since hydrazine is basically an hypergolic propellant, thus, this mixture would be HypFuel/HypOx.

3) Methane... Well, I haven't planned it either, but I think after the 1.0 ISRU feature it can be made a mineable resource ("Natural Gas" as a name of it?) and have some engines working on it. But that won't be my top priority.

About Russian: only in Russian segment, here we're not allowed to use any languages other than English.

Just found this, you've done fuel almost exactly the way I would have! I'm glad someone else thought of just splitting liquidfuel into kerosene and LH2. I would like to suggest that you consider NearFuture compatibility; NFT's LiquidHydrogen resource is already the standard for most mods using LH2, so I'd say either add an MM config that changes and LiquidHydrogen resources to CryoFuel, or just start using LiquidHydrogen instead. (And maybe rename liquidfuel to kerosene for consistency)

Oh, and KW should probably be on the list to get compatibility too. Excited to see where this goes!

Thanks! The LH2 compatibility would be nice, I think I might go with it if the CryoFuel ratio issue couldn't be fixed.

For KW: I need to have the basic compatibility, only then I could move on to other mods.
