TR-1 Rocket Motor initial CAD

Here is our initial CAD of the new TR-1 motor.  Pretty much the same layout as my first N-class motor.  Bates grain consisting of six segments, with a half inch spacing between segments.  The motor will utilize approximately 28 lbs of propellant.  I will be making the nozzle out of two sections to help reduce the machining time and so that I can use metal stock that I have on hand.
