Bill_ just curious what’ll happen next to that cute monoprop HP rocket you sold
recently. If I got that right.
One of the best machining & design jobs ever shown on AR. More importantly, it
flew & did not crash.

Subject: [AR] How to make/where to buy tanks for propellant for pressurization
with inert gas? How to meter flow?
This might--or might not--help:

In general, you are looking at a project that is likely to cost north of $5000,
potentially way north. That's not to be discouraging, just realistic. It is
one of the reasons that rockets are generally team efforts....

New to the forum. Forgive me if this is not how things work.
My general questions are:
How can one make or obtain a tank for propellant when you want to use inert gas
to pressurize it. Should I purchase a bladder and try to jam it into an old
chemistry cylinder? Or should I have the thing professionally made (for like
$2500 a piece). The rocket size is about 5 inches in diameter with a design
thrust of around 2000 lb. Kerosene and LOX
How should I meter the flow? Should I use an orifice or venturi? How can I
insert the pressure gauges and thermocouples everywhere? How do the pressure
gauges work?
Any help would be greatly appreciated?.

Dana
