So the TR-1 didn't go the way that I had hoped but it wasn't all bad. It reinforced the idea that making even a small change to your plan should be very carefully considered. A lesson worth reinforcement. The damage was not nearly as bad as it could have been and was, for the most part, limited to the casing, pressure gauge , and the bulkhead. The bulkhead will need to be re-drilled and tapped but there is enough space left to do that. The Casing is relatively easy to fabricate and I have already procured new stock. The nozzle surprisingly was relatively unscathed and after removing a few bolts that had been sheared off in it, it's good to go. I have continued going through all of my boxes of rocket and rocket related stuff in an effort to organize my workspace and found that I actually have enough sorbitol on hand to cast this motor. I will take a more stepped approach geared towards a full scale test before proceeding with another full on motor test. Hopefully this winter around December or January. The first step is a smaller single grain test motor sized for the 4" diameter grain segment.
In addition to prepping the TR-1 motor for another test I will be doing some smaller scale testing utilizing Dextrose. I plan to use the 2.375" motor that designed, tested, and flew back in 2009/10.
Originally this motor was designed for sorbitol based propellant. Ultimately it was fired with KNSB based propellant and a
50/50 sorbitol/Erythitol mix based propellant. I have constructed a four segment casing for this motor which would produce a low MEOP of 600psi with KNSB and 950psi with KNDX.
