Half Cat Static Test 7 - July 27, 2021

• Success

• Full data acquired

• Changes from previous test: Oxidizer line replaced with high-pressure version

With both propellant lines switched to the high-pressure version (since the low-pressure oxidizer line was still bursting in separate tests following static test 6), we performed a final test to qualify the engine for flight. Everything went smoothly and we got good data from the DAQ. The spike in thrust and chamber pressure for the first second is attributed to the igniter still burning and generating pressure, which can also be seen in the noticeably bigger initial plume.
