Detailed Instructions:
Follow these step to set up the testbed:
Charge tank to target pressure(2.76 absolute atm).
Place assembled thruster module on the test bed and fasten it on the plate.
Put the test bed on the vacuum chamber.
fire the valve and measure the thrust.
Calculte achievable delta-V using rocket equation.
