can i stop spinning weights in space at the right time to move a spacecraft?

Yeah, read about how the Hubble Space Telescope uses rotating weights to move.

but muh conservation of angular momentum
you'll just make the ship start spinning

wow cool i thought it was just used for rotating things but not moving linearly
though it seems that the velocity is capped? i thought itd be possible to accelerate to high speeds

in which direction would it spin? i thought if id take two spinning weights and made them spin in opposite directions like in the OP pic it would cancel out the spin

Fucking nope.

you need to "grab" on something to move through space. atm we grab on matter and throw it the opposite side of where we want to go to. not loosing mass for deltaV would be a gamechanger.

but how does the hubble move linearly then? it seems that if one rotates some aligned flywheels just the right way, then angular momentum becomes linear momentum, or am I still misunderstanding something? where do we grab here, and what do we throw to the opposite side?

it works for rotation but not for translatory motion

>engine spin
you mean the crank shaft?

Yes but you only gain back what you spent on accelerating the weights in the first place.

how do you mean that? i thought converting angular in linear velocity is already something special
