I used the wrong term I guess. I meant what would keep the vehicle from
acting like an arrow? That is trailing the pointed stick behind. It seems to
me this would be the stable mode.
I think the military uses a armor piercing projectile with a long snout. I
believe it has to do with fuzing, but it would be interesting to see how they
achieved stability with that shape. There are some interesting shadow pictures
on the web at ballistic sites.
Mach 2.5 isn't too hard to achieve with a bullet. I turn my own copper
bullets and have played around with shapes a little, but I have no way of
gauging my results (except for accuracy). I just bought a chronograph so
eventually I'll get speed measurement down.
I cut down a shotgun to cylinder bore with the express purpose of testing
shapes, a poor man's wind tunnel, but once again how can I see my results?
There is a shotgun sabot that looks like two mercury capsules neck to neck and
it is rated at Mach 1.5 IIRC, it is stable either way it flies.
