TR-1 PROPELLANT SEGMENT DESIGN

I plan to use a 4" ULINE mailing tube as the casting tube/inhibitor for this motor. This particular tube has a wall thickness of 0.080" and allows for a bit of insulation to fit between the propellant segments and the casing wall.  The motor is designed to use a propellant grain consisting of six segments.  Each segment should weigh approximately 4.75 lbs (2.15 kg)  for a total propellant load of approximately  28.5 lbs (13 kg).
