From the attached RockSim 8 file:


Even though I aesthetically prefer rockets with 3 fins instead of 4, the deployment velocities on this design were just too high for my tastes. Adding a fourth fin added enough drag to slow this rocket down nicely.

I also initially used an 8" long ST-10 tube for the lower body, but bumped it up to ST-13 to provide additional drag, as well.

After the Tau Zero and the Zeta, this is the third of my designs to use the Semroc BC-760 "Tau Zero" nose cone."


Quick! For extra points, who can point out the common elements of those three model names? (No fair looking at the RockSim file first!)
