True, it is just an experiment. I believe rockets are unreliable
because we don't have enough control over them. This is just a step in
that direction.
On an amateur level.
I also plan to convert an automotive turbocharger into a turbopump.
Using Kno3 and sugar as the gas producer to power it. Kind of a reverse
belt driven centrifugal supercharger.
I'm building a new shop and we acquired a Bridgeport and a couple
lathes and a TIG so you should soon start seeing some interesting stuff
from us. We finally got some funding!
