3 Re-starting the process of characterizing "Everclear" now that we have a new
4 1600psi pressure sensor on the test stand.
6 This was a 2-grain 54mm Everclear motor using a #24 nozzle. Ignition was
7 with one of Terry's igniters, on Saturday at the Tripoli Colorado Spring
8 Fling event near Hartsel.
10 The grains used were from the 21 May 2019 batch:
15 Small profile o-rings were used between grains, leaving the grains still
16 slightly "loose" in the case. The buna-n o-rings on the nozzle and forward
17 closure were lightly greased, and the liner exterior was heavily greased.
