Hello aRocket,
I've been having some conversations with people in the high power rocketry
community as of late regarding minimum diameter rockets encountering issues
with stability during boost when they reach the Mach 3-4 range. The
conventional wisdom in these conversations is that the failures are related
to a lack of dynamic stability. Of course unlike static stability, there's
not an easily passed on guideline for ensuring dynamic stability of a given
vehicle.
So I was wondering if anyone here is willing to chime in and shed some
light on how to improve the dynamic stability of a rocket that will see
Mach 3+ during boost?
Any advice is appreciated and thank you for your time.
Kind regards,
Drew Hamilton
