My "Spike" -- would it be stable?
I'm considering a rocket stabilized by drag surfaces; it was inspired by a "nail" rocket built by another forum member (sorry, don't remember who). Take about 12" of BT-20, an ogive nose cone like the one in the Wizard kit, a thrust ring (duh) and three or four CR-2060's (and a recovery system, probably shock cord and streamer). Space the centering rings every half inch or so starting at 1/2" from the tail of the body tube. I'm assuming/hoping that they would provide adequate drag to make the rocket fly straight, similar to the spool rocket design.
I dreamed this up a while back, but when my trial of RockSim couldn't figure out the stability of it, I gave up on the idea. Now I'm thinking about it again... Would it be stable? If not as described, perhaps with nose weight?
