I am strictly a spectator and a fan of Sugar Shot to Space. I was
invited to watch their June static test at the FAR Test Site.
Sugar Shot to Space (SS2S) is an attempt to reach space, 100km, using a
"sugar" rocket motor. Sugar is an old, simple, and inexpensive formula.
The SS2S motor is a mixture of potassium nitrate, Sorbitol, and additives.
To optimize the flight profile, multiple stages are frequently used. SS2S
attmepts to combine two stages into one motor. In this test, the lower
chamber contained two 6" Bates sugar grains. At the top of the lower
chamber resides a bulkhead. Beyond the bulkhead is the second stage which
contained one 6" Bates sugar grain. The motor case is 6" Schedule 10
steel pipe. Total propellant weight is 45 lbs, more or less.
