I know what most people think about reactionless drives and or inertial drives, but I still have some hypothetical questions about the latter. In most inertial drive setups there is usually a spinning flywheel of some sort that is balanced. Next the inventor trys to offset the balance for a very brief amount of time to create a unidirectional thrust. My questions overlook the fact that none of these devices have ever worked besides gyroscopic precession. Just play along for now that one of these devices does work as described. 1. If you had a "thrust" of say 10 newtons 4 times per second, how would you figure out how much thrust/sec you have? 2. If the flywheel is spinning at a given rate how many times could you cause a pulse (thrust) without stopping the wheel or slowing it to a rate that would be usless to your purposes? Sorry about all the make believe, but I get these things in my head and can't let go sometimes. Thanks for you patients, and if this is in the wrong place please...move it along!
