Test Stand Rehaul
I first made a EE diagram of the original stand so that we could have a better understand when we were putting everything back together
What we changed:
Changed the old COPV tank
Added load cells to the new tank
Upgraded and replaced broken sensors
Wire manage and removed all useless instrumentation
Implemented a new lighting and PA system that would allow people operating near the stand to know which state it is in and the proper PPE to wear.
We have now added our Ox run tank with a 1300psi working pressure onto our stand. It is configured the same way as the previous tank; just this tank is slightly different, as it is made of stainless steel, allowing it to have an incredibly long life cycle, meaning we don’t have to replace it in the near future. In addition to the new stand, we added a light to indicate when the stand is safe to approach (green), the control room operator can command valves (yellow), and the pressure within the stand is above 100 psi (red). We also added a load cell sensor to the Ox run tank to measure how much propellant weight we loaded into it. This was definitely the most challenging electronic work I’ve worked on, but it kept me very knowledgeable about how the stand worked, in repsect to the hardware and the code, I needed to change a couple of thing within our code to allow for 2 relay board to function, and to allow for the extra loadcell sensor to pick up how much weight we had loaded into the Ox run tank.
