The interior design of the central trunk of a ring spaceship

[QUOTE="Nik_2213, post: 6834006, member: 252015"] I think you need to look at how very much 'stuff' is in the service core of a sky-scraper. Okay, a lot would be 'side-ways' but, unless each ring is almost self-contained, probably a good idea, the central core will be 'very busy'... Getting from spoke to spoke ? Ring_1 Spoke to core to Ring_n Spoke ? I think we're talking 'turbo-lift' in core, double-ended, so able to match moving spoke and near-stationary core... All of which makes my head hurt... Alternative is to evert the problem: All rings rotate together, 'close coupled' to a 'cake stack' by their 'turbo-lift' shafts, which now resemble 'subway cars / mini-trams'. The de-spun docking and other zero-gee modules are hung off ends of apparent axis which is integral to the stacked rings. Sorry, I solved this conundrum for my 'Convention' tales, how to put spun-habs on a 'City-Class' star-ship. Unlike the elegant, almost avian designs of eg ST, my 'City' class are 'seriously clunky'. They're built from two lenticular end-shields, three modular truss girder spines / keels, paired cross-frames that variously mount 'side-saddle' habs, docks and tankage, or straddle centre-line 'Alcubierre Poles', utility pods and the fusor 'Power Section. IMHO, the surfeit of Engineering issues and potential failure modes made putting an [B][I]un-spun[/I][/B] core [B][I]through [/I][/B]a spun hab the stuff of nightmare. Much, much simpler to have two hab drums connected at their ends to ship-frame out-riggers that also provide access within ship or to/from shuttles. Third drum is generally an 'un-spun', for cargo etc. Note spun habs are essentially self-contained for recycling etc. Each is almost a mini space-station in its own right. As ship's triple spines / keels etc are modular, load-out may be readily re-configured. Take a bit longer than adding tank-wagons, a dining car and caboose to a trans-continental train, but no big deal... === 'Convention' canon: Turned out that a [B][I]double [/I][/B]Alcubierre Bubble permitted FTL without anti-matter fuel or oodles of 'Unobtanium'. "One Pole, Null-gee. Three thrust, five fly, Earth, Moon and Mars. Nine go to the stars !" [/QUOTE]
