    Is it possible to make a kerosene powered model rocket?

    Liquid motors are not permitted by our safety codes.

    As a purely technical question it would be very difficult; you would also have to have an oxidizer and all the special equipment to deliver and combine fuel and oxidizer in the right amounts. For a model rocket, a Class 1 rocket weighing less than 1500 grams completely ready to fly, it’s just not practical.

    The question might be better worded: how many people would need to suffer 3rd-degree burns before we get the formula just right?

    You are new here. This is not recommended and violation of most safe practices. Karosene is only used by government space agencies.

    If you planning to get into rocketry, I recommend you visit a club and get a mentor.

    To answer the question: Is it possible? Probably with a lot of time, money, experimentation, blowing things up, and risk of serious injury. Is it a good idea? Absolutely not, since there are far better options available.

    Also, since you're new, "model rocket" has a very specific meaning (<1500 grams liftoff weight, <125g propellant weight). If you're looking at going bigger than that, it probably becomes easier to make a functioning rocket (ie enough power to lift off and fly) but the expense and risk are also exponentially higher.

    How about we just watch these and leave it to the pros?

    FWIW any liquid rocket is essentially an extremely complicated plumbing exercise; the aeronautics are much less of a problem for (large) model rockets.

    Most liquid rockets are one or more of: teratogenic, cryogenic, hypergolic, toxic.

    So if you survive the freezing fluid turning you into a poisoned human torch, congratulations you have graduated to slow, terrible death.

    Hyperbole? Yes, but only a little bit. Please stay safe out there.

    He got the point. I think we stop piling on. Welcome to the hobby and find a club to launch with. They can help steer you in the right direction.

    Kerosene rocket would be allowed if the oxidizer is a solid I believe. If it is a hybrid it is likely allowed somewhere. Don't have the rules to look up ATM.

    Liquid/liquid is definitely out.

    RattWorks made some tribrid hobby rocket motors, basically they were hybrids (N2O liquid oxidizer and plastic fuel grain) with alcohol injection. They were never certified, so you could only fly them at a Tripoli research launch. http://www.rattworks.net/research_tribrid.html

    "I was born in this town
    Live here my whole life
    Never anything to do in this town
    Probably learn to die in this town
    Nothing to do, sit around at home
    Sit around at home, stare at the walls
    There's Kerosene around, something to do
    There's Kerosene around, we'll find something to do
    Kerosene around, set me on fire..."
