How do liquid fuel rocket engines reignite in zero-g without destroying the turbopump? (fuel sloshing problem)
Hi! This is for You rocket engineers out here! From my (very limited) understanding, a big problem with reignition of a liquid-fuel rocket engine in space is the 'sloshing' of liquid within the tanks. When the engines are already fired it causes no issue, since the g-forces during acceleration keep the fuel at the 'bottom' of the tank, where the pump is.
But how is this risk, of the pumps running empty, mitigated during reignition? I can imagine you could give the rocket a "push" with reaction thrusters to force the fuel to the bottom of the tank and then start up the pumps, but I haven't managed to find any real literature addressing this problem.
If You know something about this I would be interested to hear Your take on it! Thank You!

Im a beginner and I want to build a liquid rocket engine
So I have a great interest in rocketry and I want to attempt to build a liquid fueled rocket engine. Can you give me your ideas on how to learn how they work and how I should find the right fuel types and build the nozzle for example. Thanks!
Noticed a burning smell coming from my hood. Found some buttery liquid leaking from the oil cap all over the engine.Took it to a mechanic and he said it was fine Checked again and the substance is back.

The PGM-19 Jupiter was the first nuclear tipped, medium-range ballisticmissile (MRBM) of the United States Air Force (USAF). It was a liquid-propellant rocket using RP-1 fuel and LOX oxidizer, with a single Rocketdyne LR70-NA (model S-3D) rocket engine producing 667 kN of thrust.
Assuming we already had the means to make a closed-cycle gas core fission rocket function as a launch vehicle that relies on propellant, what would it take to make a similar device that can carry payloads to sub-orbital flight as an air-breathing engine (atmosphere as propellant)?
