Rotating sections

If you have more then one spinning section and each on rotates in an other direction the axis what is true all of them woud not spinn at all. so you go true the main centercore with out risk being cutted in half only problem there is no Gravitation. But for some things it is also a good thing. so you can move spareparts very easy from one end of the ship to the other. also you can manifacture there perfekt Balls. (what you use them for no idea)
 
Going from what people have said I think I'm starting to see how it could be done.(I sat down with a piece of paper, and tried sketching the ideas you all put forward) The corridor around the axle that extends a way into the end section idea sounds the most logical. You would enter the corridor from the rotating section, and just criuse along it to an open area at the end that exited into whichever end section you were heading to. No nasty choppy doors needed. One thing though, wouldn't the doors into the central corridor from the rotating section seem like hatches in the ceiling?
 
Okay, here's how it's done. There is a "collar" in between the sections, that can spin independently of the main section. IT contains changing rooms with grav boots, etc. It spins with the spinning section, people enter. People get changed. It stops spinning and aligns with the non-rotating section, people disembark the other door. Sorted ;)
 
Wouldn't there still be a bit were you had to wait for doors to line up before you went through? And wouldn't the spinning motion seem quicker the closer to the axile you got?

Yes. The door needn't be a chop-you-in-half, though - if there's a 'collar' joining the two halves of the rotating section, with a continuous torus of open space inside it, you merely leave the central passageway (zero g) and cross to the wall of the rotating section (minimal g), then clamber up (actually 'around') the inside of the torus to the entrance to whichever rotating half you need to enter. The collar is moving relative to the central shaft, but at no point is it 'cut off'.

Really, really could do with a picture to explain


And no, you get closer to the axle, you move slower. It must move at the same angular speed or else it falls apart. If you do eight revolutions per minute (or whatever) then at the outside edge you're moving faster, because each revolution represents twice the distance as it does at a point halfway out from the centre.

This is the problem with the omega; if you want something resembling 1g on a given deck, you get 1/2 a g on decks half-way out and 2 g on a deck twice as far out. Simply having a rotating section doesn't give you proper gravity all the way through. You'd get 1 g (maybe a bit more) on the outermost deck and a linear decrease to zero g at the edge of the rotating section.
 
just saw this dunno if its an answer?

Heh... that basically says there is no way to get from the spinning secton to the static sections!

that could be a real problem if one sections toilets broke!!

B5 Tech[/url]"]To provide a stable turning axis, the center section rotates around a drive shaft; a reinforced hollow bar that runs between the rear and forward section. Rotation is accomplished using an advanced superconductor motor similar to those used on the hover-trains on earth. This prevents wear on the drive shaft and the rotating section, as the electromagnetic super conduction system floats the rotating section around the axis. As there is little to no physical contact between the forward, rear and rotating section, as well as the axis, Omega class Destroyers experience almost no frictional deterioration.

Almost sounds pretty good, however when combined with the descriptions of the three sections some pretty horrible design flaws begin to kick in.

B5 Tech[/url]"]Destroyers are broken into three sections and each section is designated for a specific function. The forward or Hangar section of the ship is a zero gravity environment that is designated for star-craft support, main weapons, and the ship's main sensor/communication array. The ships main storage bay is also housed in this section.

Ok, so we have the forward section full of fighters and comms gear as well as about half of the lifeboat pods. And most of the stores. There is however no way for the crew (or the pilots) to get into this section....

B5 Tech[/url]"]Center or Habitation section is where the ship's control and command reside, main bridge and two secondary bridges. It also includes primary life support, crew quarters and the ships main computers are contained in this area. The habitation section also houses the ships secondary storage bays, as well as a small botanical garden of limited potential.

Well at least the crew have a nice park to wander in as they try and figure out how to get out before the secondary stores run out. I also guess that the computers would have to talk to weapons and engineering by Wi-Fi...

B5 Tech[/url]"]The rear or Engineering section an Omega class Destroyer is designated to the ship's ion and jump engines, fusion reactor, primary and secondary fuel tanks and aft weapons array. As neither the forward or rear areas have gravity, the boots of Earth Alliance personnel have Velcro tipped toes which prevent them from floating off in the zero gravity areas of their ships.

So the crew have velcro boots for when they are floating about in Zero-G, however as they seem trapped in the rotating section this seems a bit pointless....

Obviously B5Tech needs to think things through a little better. Or figure out doors and stuff.

My take would be to have a hollow, split shaft though the middle of the vessel over the rigid connecting shaft. Basically lifts then run through the Zero-G section to the tops of the rotating section stopping at each deck. The hollow tube surrounding the connecting shaft (see the axle arrangement part of the Falkirk Wheel's clip - 45 to 50 seconds in).
You could then run a train like thing to move personnel the length of the ship through the zero-G sections. Think also the transport tubes/low grav train stuff within the centre of B5 itself.
 
How do we know it's the centre section rotating? It could be still and the other bits, the camera, and supporting ships are rotating around it! eh? eh!

And the planets in the background could be spinning, too!

The universe is spinning arund the middle secton of an Omega...

just remember that your standing on a planet thats revolving, revolving at 900 miles per hour.... thats orbiting at 19 miles a second, so it's reconed, the sun that is the source of all our power....

"Spin the planet"

"But you said you wouldn't!"

"I said I wouldn't destroy it. I said nothing about spinning it! Spin the planet Princess, BWHAHAHAHA!"

Or am I the only one who has seen that...

I'll get my coat...

Not as funny as Burger's take, but...

Hidden inside the centre of the rotating section (or 'spin hab') there's a massive counterweight spinning like crazy in the opposite direction to balance the angular momentum. That's what keeps the rest of the ship from rotating.

And the gyroscopic effects of all that spinning metal are why the Omega maneuvers like a pig.

Getting from the spin hab to the zero-G parts of the ship would involve a ride in an elevator (think Star Trek turbolift). This would move across from rotating to non-rotating sections as the ends of its tube lined up with each other, thus preventing clumsier travellers occaisionally being cut in half.

The axle the spin hab turns on is hollow, which allows access from the forward axehead with the fighter bay et.c to the aft section, which apart from the main engines is mostly propellant tanks.

That's how it works in my pocket universe, anyway.

A couple of friends and I were having a drink last night and trying to figure out how you could engineer an omega so you could get from the central rotating section to either end without getting squashed in gears, or chopped in half as a doorway slid past. We had trouble seeing how it could be done. (admittedly we are an embalmer, computer tech, and a barman. Not an engineer, or starship designer to be seen.) Any ideas, or should I put this on the slighty drunk conversations shelf, next to my mates idea about how to sell the air that Jesus breathed.

Get right into the centre of the rotating section as that part of it woun't move at all, and then have a tube that leads to the front and back of the ship
