[LetoII (OP)]

If i take a maglev like rails which is formed in a circle, in what different shapes could it move in space saying the weight of the system is 80 Kg. the mass of projectile inside is 20 Kg. and there's no huge limit on the propulsion that can be delivered to the projectile inside.

i'd like to start with this configuration and add some variables after there is some agreement about what can happen in this sistuation.

Are you thinking of some sort of EM gun?
Sending out probes maybe

Nice idea if so.
Think I've seen something similar in some SF too

probes are king, manned missions will have to come after those
but back to the issue, for this stage i think different shapes / movement patterns will arise from using different acceleration rates.
if you use a really low rate then the total object stays in place rotating but if you increase it you'll get an actual circle pattern that grows in size as you add greater acceleration. using increasing / decreasing acceleration would allow you to make a clover like pattern (and more).
