Full grain test with modified mild steel nozzle
Preparations are underway for the launch of the N-2 rocket. The schedule has not been decided yet, but we are working with KSA for mid-July. Today, the propulsion team conducted a static test. It was a solid motor test using two grains, the same as the one used in the main test.
Unfortunately, I had a meeting and could not be there. I was shown a video later and found that the side wall near the end cap had melted, causing the gas to blow out in the middle. The nozzle also melted last time, but this time it was safe because we changed from aluminum to mild steel.
