Does anyone know if an old aluminum gas cylinder (AT size, 1.7 ft^3) can be
modified into a propellant tank for an inert-gas pressurization liquid fueled
rocket. The maximum regulator delivery pressure to the tanks is going to be 800
psi and the pressurizing gas is Helium. Fuel is kerosene, oxidizer is LOX.
?Can I simply drill a hole in the bottom of the tank and fit it with the
necessary connections as the propellant inlet/outlet? Should I use the body
(tube) and cut off the top and bottom and replace them with hemisphere caps? Or
is it a better idea to get a completely new tank fabricated.
It would work wonders for my budget if I could in any way "recycle" an old gas
cylinder, no matter how minimal. Any input would be greatly appreciated.
Cheers,
Dana
