- How did you get combustion chamber pressure and thrust measurements?
- Dumb question, how does the bulkhead for the injector not get blasted
out of the combustion chamber? I really don't know much about bulkheads
so a bunch of detail in this aspect of rocketry would be highly appreciated.

What does this do?
Oh wait, if the grain is put inside of the steel casing,
How do you secure it? Does it need to be secured?
In text, what is the "general" fuel grain manufacturing technique, I see
the images but would like some elaboration.


I'd expect the pictured Circlips in apropriate groves ( in the casing ) to hold the plugs in?
