I love rockets. Planning to build a tin rocket but not with water and air pressure. I would like to build a small metal tin rocket using fuel as RP 1 and oxidizer as LOX. I know this is too hazardous please don't try this. Is that possible to build a metal tin rocket with the same fuel used in real rockets?
- the heat of combustion would soon melt your plastic bottle. RP/LOX rockets use special high-temperature metals like Inconel, and then still need to cool the nozzle to prevent melting.
- a plastic bottle becomes brittle when you try to store LOX in it, it's unlikely to be strong enough to hold the LOX at any pressure
So we'd be talking about a different kind of rocket here: one built from metal, using two tanks to hold the LOX and RP, and with a combustion chamber to mix and ignite them.
The next step up from a bottle rocket is not LOX/RP. It's an Estes solid-fuel rocket.
