Brazos Test Stand

Most US based amateurs I see working on bipropellant thrusters fall into 2 categories:

Professional engineers doing this as a hobby for fun, relying on professional experience so that they dont need to do as much testing or dont want to work on/spend the money for as capable of a system as they could build
Student teams lacking some combination of relevant knowledge, money, manpower, etc. to design, build, and utilize a highly capable test stand. The 4-5 year graduation cycle means even the best individual contributors get old and eventually graduate, puting institutional knowledge at risk

I'm planning on changing that(see the above P&ID for the test stand I am planning), if you would like to support my work you can donate on Artizen. The platform often has a match of some kind running, meaning even a $10 donation can contribute $20/$30/$40 dollars to the stand. I am working on donation incentives at the moment. Some additional details on funding etc. can be found in this presentation:

TLDR: The goal is to build a test stand so that I can test a suite of thrusters and build a dataset to create a version of the excellent NASA SP-8089 Injector guide targeted specifically at amateurs(especially students) for use designing nitrous oxide(especially self-pressurized nitrous oxide) injectors to increase performance of what people are able to build. I would love for the data to somehow make it possible for the first amateur liquid propellant space shot to happen, or at the very least help more teams go higher than 10,000 ft.
