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

  Why the Change!? The following changes resulted in a large test stand redesign: No longer able to test at FAR Need to make a mobile test stand Stand was over budget, need cost reduction of a few thousand dollars The new design is built around a 275 gallon IBC tote. On test day the tote will be transported to the test site with all of its fluid components already attached. The outer steel frame that takes the load of the engine will be placed under the tote and then the tote will be filled with water to hold everything in place. This design is nice because we don't have to make any modifications to the environment we're testing in and everything can be moved in a U-Haul truck and carried by two or three people.  The P&ID Things to note: Nitrogen purge valves replaced with solenoids Regulators replaced with orifices Small bypass regulator for leak checks Fewer relief mechanisms Thinner propellant and nitrogen lines After remaking my fluids calculator in MATLAB, I found that
