Hello!
So I've been occasionally popping into here to ask questions about a hybrid
nitrous oxide + paraffin mixed with carbon black engine. I've gotten a good
idea of what I want to do with the engine, but now since I finally have a
job and some disposable income I can start buying things and actually make
a schematic of a design.
So, how to math?
I know NASA had some site that has a very in depth calculator for some sort
of either ISP / thrust / fuel or something, but it's broken as far as I can
tell and I don't know of any alternatives. I think it would be better to do
more math and get a more specific design set out as i'm not going to be
building this for a while anyways, as I still lack access to a lathe and
mill due to coronavirus.
In the meantime, there was an email about a dirt simple DIY nitrous rocket
that somebody had sent to me, and it looks like a fun project to just get a
toe in the water when it comes to rocketry so I know how to deal with
engines and what's safe and just get a feel for them, so i'm wondering what
are some best practices for nitrous oxide handling, and what i would need
for a simple plumbing system that would run a tiny ~4inch rocket. If
possible I would also love a design that mimics what I would require for my
hypothetical rocket so far, that being the nitrous. If anyone has any good
resources, that would be absolutely wonderful. An overkill setup would
ideally be perfect as the best thing I can think of is a very "boring"
static fire.
I'm just getting into physics and calculus now, but I don't particularly
think that the equations would be too complicated, and if they were, I
think I can work through them or ask one of my teachers for help.
Thanks so much for all the help, ya'll been a great help.
