TR-1 MOTOR CASING

With this drawing, I now pretty much have all the drawings that I need to begin cutting metal in earnest.  I plan to go back and update these drawings.  I don't really need a drawing for the bulkhead as it's identical to the nozzle ring in thickness, o-ring gland placement, and retaining screw locations.

TR-1 motor casing

The summer has been busy so there hasn't been a lot of Rocketry getting done.  I have been working on a test rig for the SStS program that will be used to test tensile strength of propellant which will have varies additives designed to increase its strength.  This is a pretty interesting idea and the results could help open up some new possabilites for sugar based propellants.  The TR-1 rocket motor hasn't moved forward much, but I have gotten the 4" EMT (seen above) for the motor casing.   I'm hoping to be able to start construction of that motor in earnest soon.
