Propellant Mixing Questions

Ed Giugliano · 2003-11-19T17:54:21+00:00

I was a little surprised to see people mixing their own APCP on RocketChallenge. Some questions for those of you who have "rolled yourown":Is this a common occurance in HPR?What kind of quality can you get from home made APCP? (Does home madepropellant tend to cato, have combustion instability, great batch tobatch variation, or other problems?)Any safety incidents? (accidental ignition, near misses, etc)?WHY do you mix your own? (cost, can't get the right size motor, fun,etc)I'm asking this out of curiosity. I am not associated with any rocketcompany or any government agency (real or imagined). I am merely alow/mid power rocketeer killing time on my lunch hour.

both ARSA and IEAS will have new clubs formed throughout the U.S., and IMO the east cost (esp. northeast) is especially ripe. John Wickman has said that the number of new member requests he received this month is unprecedented, many of whom are have expressed interest in forming local groups

I don't know of any EX launches closer than 3 hours from New Yoik City (my hometown), the closest is the far side of CT, but those are rare. They would be CTRA/NARCONN (NAR) with a 5,775' AGL ceiling (75% of waiver). I haven't seen any EX launch announcements from CATO (Tripoli).
