'allo!
I am currently a 10th grader trying to make a resistojet for a science project in an attempt to find out which heating filament geometry makes the resistojet most efficient (if changing the shape changes performance at all). A resistojet is a mode of propulsion that uses resistive heating (thus, the resisto- part) to heat up a filament that heats up a gas flow to generate thrust.
What materials are needed and what safety precautions do I need to remember? So far, I'm thinking of using aluminium as the material for the structure and using water as the propellant. No idea what to use for the heating filament. Probably a copper coil.
Thanks!
