This is another test of CXP18, the same propellant used in Static Test 54 only I used DOA to thin it out a bit more.

For a 500 gram batch I used the following:

AP: 367.5 grams, 73.5%

R45M: 56.25 grams, 11.25%

Al: 50 grams, 10%

DOA: 18.75 grams, 3.75%

Mondur MR: 7.5 grams, 1.5%

This batch was hand mixed, and not degassed. I have a theory; with thick propellants degassing may actually decrease the density do the bubbles created by the degassing process. The propellant is so thick the bubbles created can not escape. I also think mechanical mixing may add more bubbles to the mixture as well.

The grains were cast into (4) 1.5" PVC pipe sections 2.5" long.
