One major advantage that SR2 has over stock SR and KSP is its costumizability, but that unfortunately gave in at the rocket engines. So I have the idea of...


ADVANCED CUSTUMIZABLE ROCKET ENGINES!


These engines will have the following costumizable attributes:

  • Fuel type: RP-1, Hydrogen (please add hydrogen), and Monopropellant. (Monopropellant engines have a size and thrust limit and only one engine cycle-pressure fed)

  • Size: ONLY affects the combustion chamber size, which determines the base thrust. Also determines base mass and cost.

  • Engine cycle: Determines the efficiency (changes thrust based on base thrust) and additional mass and cost of the engine. Available cycles are:

    1. Gas generator cycle (low effeciency, mass and cost)
    2. Staged combustion cycle (High effeciency, mass, cost)
    3. Combustion tap off cycle (Medium effeciency, mass, cost)
    4. Electric pump cycle (high effeciency, low mass and cost, requires a lot of power to run, limited to low thrust)
    5. Expander cycle (High effeciency, medium mass and low cost, limited to low thrust and hydrogen fuel)
    6. Pressure fed cycle (high effeciency, low mass and cost, limited to VERY low thrust, only engine cycle available for Monopropellant engines)
  • Expansion ratio: Affects nozzle size and thus engine effeciency in different parts of the atmosphere (probably will only have a high, medium, and low choice for simplicity). Also affects additional mass and cost

Suggestion Planned

    @mjdfx150529 and make it a UI like this https://cdn.discordapp.com/attachments/240866472660828160/513804296723234832/20181118145306_1.jpg

    @AnotherFireFox This is getting overwhelming complicated

    One more thing: Turbopump rpm, regenerative cooling ratio and feeding pressure for each engines to determine thrust.

    Thanks everyone for the massive support!
    I didn’t expect many people to understand a thing that I am saying

    @bartekkru100 We have monopropellant though... Not the same thing but also highly toxic, low Isp, room temperature, and "hypergolic-ish"

    Hypergolics would also be nice for that extra toxicity they give.

    and oxidizer too! I need oxidizer!

    @Gregrox Nice! You could @ AndrewGarrison in your post!

    @Gregrox To be clear, I mean that you would NOT use oxidizer in NTRs, but still have hydrogen on its own at the correct density.

    And I'd like to add that you should add Oxidizer requirements as well, since Hydrogen on its own is nowhere near as dense as Hydrogen+Oxygen fuel for an engine, plus it means you can do Nuclear Thermal Rockets in future.

    It's a great idea. Thank you for posting.
