Test Stand for a 1000lbf Kerolox Rocket Engine

  The Project This project is what I like to call Rocket Kart 1.0. It's a test stand built entirely out of 80/20 designed for the capacity of a 1000lbf ablative kerolox rocket engine. Equipped with high flow engine purges, load cells, PTs and TCs and several safety mechanisms, this test stand will serve all kinds of projects for many months to come.  Overview Looking at the stand's P&ID you can see the high flow purges and pressurization system are fed by two 3kpsi GN2 tanks. These feed into the their respective propellant circuits. Given the often unpredictable nature of fluids inside of a 3D printed injector, there are two regulators for each propellant. This will allow the user to control the set pressure of each tank in the event that the pressure drop across the fuel elements is different than that of the oxidizer (which it often is). Moving further down, each tank has redundant relief mechanisms, one burst disc and one relief valve, and a fail open vent in case our st
