Impulse Space Drive Idea:

[Oxygon]

this is what I was thinking...

Note: the starting points are further from the axis...

You can speed up a rotor casing with two or more ball weights inside...

At this point you can add as much energy to the motor as possible...

Then... you can stop it and the torsional energy will be redirected by the inner path into a short and sudden forward/directed force into a wall/ship structure... of course this force could be dampened in order to protect structural stability...

What do you have to say...?

here the key is the intense power from the rotation is switched into a directed force quickly...

your thoughts...

p.s. - bring the weights back should be easy enough... to restart the motor.

p.s.2 - the push/pull/whatever should be great, I am assuming from the input rotation...

p.s.3 - this is not an F/E idea.

You will need to stop the motor real fast and sudden. This will put a reverse torque on the motor housing causing the craft to rotate. So you'll need pairs turning opposite directions to compensate. Then when the motor(s) start up again the balls fling back to the starting location and you get a reverse effect. If the motor starts slowly I would think the reverse thrust would be minimal?

So you put many small motors in an array to abtain a smoother thrust. And somehow use the braking of one motor to spin the next so as to conserve energy.

I'm not sure I understand. The idea is to turn the rotor, and because of the ball's inertia and lack of attachment to the rotor, they will be driven along pretty much axially, and then they will suddenly impact the end of the rotor? It seems to me that the impulse at the end of the rotor is countered by the weaker force that acts for a longer time (but which has equal and opposite magnitude when you multiply those two) caused by their initial acceleration. (They accelerate by being pushed by the internal helix of the rotor, but because of their inertia, they push back by an equal amount, which means the craft is already moving, in the wrong direction, before they impact the end of the rotor).

JIM.....DOT if you use the good dilithium crystals..... and stay below "warp speed "... but scotty would be the engineer....: Spock.....could get them to work........with the doc's help............
every episode....... SPACE...THE LAST FRONTIER.......SURE HA i bet thay never tried bilding a (PPM ) machine ....!

Just like Jonathan said. So the net thust is zero.

At the start the balls are at the bottom of the curved slots. The motor starts to rotate. There is NO axial thrust while the motor rev's up. Then the motor slams on the brakes stopping its rotation. Inertia will rotate the balls forward against the ramp, pushing the balls up the ramp and pushing the ramp (and ship) downward, in the wrong direction. Then the balls hit the end of the ramp pushing the rotor (and ship) upward. Looks like it balances and no net thrust.

maybe so...

Jim what if we pulse the motor on and off so that the balls are allowed to drop back approximately half way...then shoot up to their ending positions?

Oxy, hi there!
I guess I know you from other group. :]
There are types of mechanisms that you should search by near.
I'm talking of mechanical rotatory vibrators. They allow to users a lot resources and ways for to manage their ''resultant''.
The source, of sure, is electricity and the power transmition is great.
Case you need, I may talk more about ideas on this. Regs. M.

I don't think it would make any difference.
