Coulombic Spacecraft Propulsion

09/30/2013 3:33 PM

I have a rather simple question that I likely should know the answer to.

The question is:

Suppose we had an electrically charged spacecraft whose largest dimension is much smaller than the seperation between two charged plates at different potentials. Further suppose that the spacecraft is thrusted by another mechanism not related to coulombic repulsion and attrraction.

Would not the spacecraft experience the same kinetic energy gain component if placed in the potential between the plates as a result of the coulombic field effect mechanism regardless of whether or not any additional modes where operative unrelated to the coulombic mode?

My thinking is that the craft would still undergo the same electrostatic propulsion over the same distance regardless so that the Int F dot dx omponent would be the same in any such case. I presume that in cases where the spacecraft charge is held constant, the same results would accrue regardless of whether the spacecraft was traveling at relativistic velocities or not.

Thanks for your consideration.

those new fangled electric spaceships aren't nearly as reliable as the old rocket powered jobs.

OK.

but what if? When?

I like your newfangled cicle.

The "kinetic energy gain component" is inversely proportional to the flux density of the integral, multiplied by the reciprocal of the square root of the RMS power generated by the two charged plates divided by the separation of said plates in meters. This is factored into the density of the air over the relative humidity and density altitude.

Any additional modes where operative unrelated to the coulombic mode will have little or no effect on the operative cumulative effect on the energy quotient of the motive force of the spacecraft.

Unless, of course, it's after the sun has gone down...........................

I was considering a stellar or solar system scale disposition of plates charged to a known relative potential and a highly charged spacecraft located near a repulsive plate and heading toward an attractive plate. Given the potential between the plates, I would assume that the energy component gained by the spacecraft traveling amidst the potential would be equal (Qtotal)(V) where Qtotal is the charge on the spacecraft in coulombs and V is the potential between the first plate and the second opposing plate in Volts. Thus, the result would then be expressed in Joules. I assume whatever unspecified mechanism is used to maintain the plates in a spaced relation.

Would this relationship hold even for relativistic spacecraft even where other propulsion modes are used that provide a significant fractional additional component to spacecraft kinetiic energy?

I am neglecting fringe effects near the edges of the plates.

Any body have any intellegence at all here. Let's not get insulting. I know exactly what I said and have emailed jorrie to obtain a rational and mature response. Appearently, I will only get nonesense here. Must have pissed someone off here. I have plenty of other colleagues not related to this website who will be willing to help. I thought I'd give you folks one last change before giving you the flick-off.

I meant it. I didn't have a clue, and I admitted it.

I was joking.

Never mind.

No intelligence here.

Little bit on yourself, are you? If you want to play with more intelligent kids go ahead if the reasoning, practical and joking intelligence of a couple of old fartz engineers does not suit you.

I'm not sure, I was just dropping a few fancy words in a vain attempt to impress those more intelligent and experienced than myself.

Issues! Issues? We don't need no stinking issues.

Repulsive language paired with religious statements show the league you play in is not the Earthly intelligence. Where are you from??? But even more: Where do you want to go? I hope your propulsion works and gets you far away. Its seems necessary that it works for once and would be better for -Huh- say all of us!

Not only will this idea not work, it will never fly. Who is supposed to go there first, and install the charged plates, and since the force dies off with the separation of the plates (squared?), don't count on there being any measurable acceleration when the distances are in astonomical units. In other words, you should direct your thoughts to something that has a chance of working, like the internal combustion engine for example.

Someday the space shuttle Coulombia will be built like this. In a galaxy far away, etc....

Sounds like what happens to an electron in a CRT.

Right, except for a little matter of scale, and of course the CRT and electrons actually exist and we do have a way of charging the plates of the CRT.

To the OP: Although your question has no connection to reality, the answer is yes; the coulomb forces would act independently of any other forces acting concurrently on the spaceship.
