Static sugar motor test of the Sugar Shot to Space DoubleSShot test motor DSS TM-2. This was the same motor tested last month successfully as a two 6" grain sugar motor but has a single grain with mid bulkhead addition. See youtube video 'DoubleSShot 6" 2-Grain Sugar Rocket Motor Test'
This test included a third grain, located behind the new Delrin mid bulkhead being tested, to be fired 5 seconds after the first two grains burned out, propellant was sorbitol and KNO3. Motor pressure exceeded planned chamber pressure and the two motor cases separated at the mid bulkhead. For more information, go to sugarshot.org
