Not sure if this has been done before, but I've just recently had a new idea:
Spin stabilization has been a concept that's been around in rocketry for a long time. But just how fast can you spin a rocket, and just how far can you benefit from it? Do you even need fins at all if you get it spinning fast enough? Take a look at a bullet, for example. It has no fins. It is, however, exiting it's "launch tube" at supersonic speeds, but perhaps this can be related to rocketry.
I imagined a launch pad that uses an electric motor to spin the rocket extremely fast, say... 1000 rpm. One point of concern is the electrical leads for the igniter. You would need to use some sort of conducting bearings, or even an onboard ignition system triggered wirelessly.
Just a thought.
The main question I would like to look into is: Can spin-stabilization be effective enough to have a rocket with no fins? At what angular velocity? With what kind of rocket geometry?
