Just make your engines big and with big fuel tanks and relatively small payloads and try to keep the habitation zones away from the engines and it's pretty much realistic.

also, it depends on what the ship's mission is and how advanced it is. more advanced would mean it has smaller engine size to ship size ratio. and warp or jump drives would also drastically reduce the fuel needs.

Rule of thumb:
Pulse drives - pusher plate (convex, everyone usually gets this wrong), squat and solid superstructure. Build it like a short, squat Ironclad.
Constant impulse reaction drive (chemical, NERVA, VASIMR, etc) - space-frame structure, spherical or rounded-cylinder pressure vessels. If nuclear-powered, reactor is on a long boom at the rear with the drive, and there is probably a solid 'shadow' shield next to the reactor (rather than next to the crew areas, to save on mass). Fuel tanks clustered between the crew area and drive for free shielding, but most fuel stored in the walls of the pressure vessels as cosmic ray shielding.
Drones: tetrahedral booms with gimball thrusters on the end. Provides full 6DOF with minimum number of thrusters.
Crazy drives that pelvic thrust in the general direction of the laws of physics - Go wild, but try and do it consistently and with an internal logic, even if that logic is incorrect.

>Got any more spacefaring creatures in the works?
None worth mentioning. I have flirted with many ideas, but so far "kobold world" is the most developed. Which isn't saying a whole lot.

>a story to this stuff?
Not yet. I am, however, developing the world's history.

Koboldworld (call it Strikis, I suppose, as a working title) is a planet far from us, and for the vast majority of its time in this universe this planet orbited within the habitable zone of a relatively dim K-class sun rather smaller than our own. Strikis is Earthlike, and not: Possessing a 26-hour day, a richly oxygenated atmosphere, and an abundance of water as well as a moon to provoke tides, but twice the mass and 3/2 times the surface gravity of our little blue speck, greater air density at sea level, and a pair of thinly populated Trojan asteroid fields at its solar L4 and L5.

[sketchy about the astrophysics.]

Centuries prior to the "current era" of the world, a brown dwarf (~.070 solar masses) -- call it Plalgis -- transited through the star system, upsetting a number of small objects but also making a pass close enough to Strikis to tug it from its orbit, sending it careening through the outer system with its new parent. While in another circumstance this might have spelled icy death for most of the planet's ecosystems, Plalgis's path through the system put it on a collision course with the resident gas giant, a voluminous world of nearly 15 Jupiter masses. The ensuing absorption raised the brown dwarf above the fusion limit, transforming it in one stroke from a lukewarm ball of gas to a shining, albeit quite dim, sun. Strikis would not freeze after all.

But not all ended well. The transition itself upset weather systems across the planet, loosing ferocious storms that tore through Strikis's many varied biomes. And as it settled into its new orbit near the outer edge of Plalgis's habitable zone, it grew colder, sinking the world into a more or less permanent ice age.

This was where the kobolds came in, in one sense, as for their then-agrarian societies Plalgis brought about the end of the world as it had been for long before. The expanding ice caps robbed water from the rest of the world, often turning once-lush rainforests in the tropics to arid land. In other formerly hospitable parts of the globe, massive glaciers and wide stretches of tundra marred by permafrost encroached on arable land, in some cases obliterating entire countries through starvation and hypothermia. Formerly prosperous port cities, cut off from trade by receding waters, shared in the suffering. Finally, there was Plalgis itself, which presented a particular religious dilemma for almost every society -- namely, what to make of the whole business, for no kobold at the time had had any idea what a "brown dwarf" was or really any extensive grasp of astronomy in the way that we know it today.

All in all, extremely rough calculations for a launch vehicle to (what I presume to be) low orbit, corresponding to a delta vee of some 11.6Km/s for my setting, yield a spacecraft total mass around 250000 metric tons. Using the volume equation for a simple cone, and height/diameter and density similar to figures given for an EM railgun launch system and for various real-life and imagined spacecraft hulls, respectively, reveals that such a vehicle could be around 5 times the breadth of a Saturn V and as tall as the Chrysler building. The top left graphic in the last upload represents my attempt at an educated guess as to what such a vehicle might really look like -- shorter, and perhaps fatter, with a large Orion-style shock absorption system taking up a good deal of the projected 250 kilotons total mass in order to dampen G-forces and make the launch blast more survivable to complex automated equipment. Not shown: "Scoops" and "bore riders", to aid the vehicle on its journey through the launch tube and to be discarded (by explosive separation?) after leaving the tube.

Another other high-capability and relatively simple-tech solution to the question of how to lift tons of shit into space is, of course, the Orion nuclear pulse system (the one I portrayed in the first image of this thread was of the mini-mag variety, hence the "oddly" placed equipment for those who mentioned it) which would also be survivable to living creatures, albeit with a somewhat awkward acceleration profile.

Pre-nuclear solutions that wouldn't launch a ton of shit but might cut down launch costs include the air-lifted booster and its mothership, which I presume to be more effective on a world with a much thicker atmosphere than Earth's, 1.5x higher gravity notwithstanding. I am sure there are holes in that theory, so please, feel free to demonstrate to me how wrong I am.

Development of armor concepts -- helmet
For a kobold to wear a helmet mapped purely to the facial structure I've designed seems like a fairly bad idea: A helmet that covers the snout would have at least some inward curvature at the nasal bridge/between the eyebrows, and would, I imagine, make things worse in the event of a particularly forceful strike. Correct me if I'm wrong, but to the end of protecting the nose I drew the armor with a sinus in the area covering the snout to make it more rounded, and thus be better able to absorb a blow. Floppy ears might simply be stuffed into a rigid helmet, but for purposes of decoration or as an alternate design the area over the ears could be adorned with scale/lamellar/laminar armor plates.

Odd question, but would those guns be something around a 5 millimeter given the size of the marksmen? I mean, part of the psychological base I give my kobolds is they hate sudden/loud noises.

Thus while they make objectively superior marksmen compared to my Verhimen (faster to train, slighter heartbeat, superior sight) they generally lack the discipline and inclination to use most firearms effectively, preferring suppressed airguns at most, and crossbows or blowpipes as a rule.

That's one hell of a tether that can take thousands of nuclear pulses without ablating away or degrading in tensile strength from neutron and gamma ray bombardment. Though I hadn't thought at all about pulse-draggers before. Maybe pump the bombs out the front, and use an enormous combination solar/particle/magsail? You could be almost completely hemispherical and achieve higher efficiency than a convex pusher-plate. Though you'd still need to deal with particle erosion so would need a bulky sail, and the PRF might need to be lowered. High Isp, low thrust? At least your mega-sail wouldn't need to be as rigid as a giant hemi-pusher would be.

Since you guys seem to know a lot about space travel, I want to ask a curiosity.


Would a biodome be feasible in space? One that can run on solar panels and produce oxygen? A sort of greenhouse, if you will? Bonus points if it's built IN a ship.
>>
No. 13016 ID: f04e7d
>>13015
Yes, it's feasible. In fact a "biodome" of some sort is a pretty important design element of at least a few proposed interplanetary missions to say nothing of a generation ship or something similar. Solar panels don't work very well beyond a certain point out from the star, though, so I usually design my cruisers as running purely off a nuclear reactor or some sort.

>>13013
It's supposed to be more like Project Daedalus than Orion—much smaller pulses at a much higher refire rate. If I recall correctly, the thrust was supposed to be directed by magnetic coils, so (at least in my speculation) it could be directed in a relatively tight column to avoid blasting the tether. But correct me if I'm wrong.

I would wonder what sort of penetration and stopping power their weapons would get, looks to be chemical propelled, they started messing around with flechette and gyrorocket ammo by any chance or going with the old FMJ standard?

Not that .22LR is a poor round, especially if one is fiddling around in a space station. Hell, the American-180 can chew through concrete if you care to empty the whole magazine.

It's just I could imagine them running into a bit of a shock if they found out most other species were rather less... space efficient (assuming there are other species to be feasibly found in your setting.)

>mag confinement
Yeah, that would work. Aneutronic fusion or M-AM annihilation would mean you just deal with pure gamma (assuming perfect confinement of charged products). Most papers on gamma effects on carbon nanotubes are paywalled (from a cursory google at least), but from the abstracts it sounds like gamma bombardment in a vacuum causes defects (and interestingly, cross-linking) in SWCN and MWCN, but only above a certain energy (>~100kGy), so wrapping the tether in a blanket of Lead/DU/something dense to sap the gamma pulse energy should do fine for long-life tethers.

>>13015
If you've got ample sunlight, you can skip the solar cells and illuminate your plants/algea/whathaveyou directly (using chevron mirrors rather than glass/saphire/etc to avoid irradiation). Though as wryt mentioned, if you are far from a nearby star then you'll have to provide the lighting from on-board power.
You might get marginally better efficiency from a purely chemical CO2scrubber+O2generating process*, but plants have the benefit of occasionally providing something less monotonous to eat too, and being generally nice to walk/float about in when confined aboard a tin can for a few centuries.

* Per weight, which is generally all that matters in space. If you really need to keep volume down for some reason, then direct chemical is the way to go.

Nooo, that's actually a pretty poor choice of round in a space station. Generally if you've already made it aboard the thing you don't want to let a perfectly good space station just go to waste by fucking up all its vital shit unless you have to. I envision them using shotguns, flechettes, or special rocket-propelled rounds of some type. The one standing in front of the jet fighter is holding a gyrojet.

Probably. I dunno what you mean by space-efficient, though.

I was comparing the .22 LR's 'space safety' to say a .45 or any other various larger or higher powered rounds, the ones most (human) shooters wouldn't laugh at for being so tiny (albeit I've heard statistics indicate well as to it's lethality.)

Not sure how gyrogets or shotguns would play into that though, fragments and shot arn't exactly something I would want floating around inside with microgravity and gyrojets wouldn't benefit much from the 'jet' in the close quarters of a boarding action.

The space efficiency was just a pun on kobolds building Orion engines, while still being short enough to stuff inside of the standard duffel bag.

Actually, a big & slow round like the .45 (ACP) would be preferable to a small fast .22LR in the Not Making Holes In Lots Of Important Spacecraft Bits department. You want something that dumps a lot of energy into the first thing it hits and then stops completely, rather than a fast round that keeps on going.

I know nothing of bullets and firearms, but that sounds an awful lot like a hollowpoint. It destroys liquid-based things, but shatters against solid things.

To an extent: a hollowpoint is designed to splay apart (not necessarily breaking apart completely) creating a larger wound channel, and will do so when it hits something with enough resistance. They can still pass through a significant amount of solid material before fragmenting (see the original Box O' Truth: http://www.theboxotruth.com/docs/bot1.htm).
You may be thinking of frangible rounds (e.g. the Glaser Safety Slug), which are designed to break into a lots of very tiny (and almost harmless) pieces on impact with almost anything. The idea being that you can fire one in a plane without worrying about puncturing a hole in a vital bit of wiring or fuel line (NOT depressurisation, that's not a huge issue at commercial airliner altitudes), or to reduce the chance of a round passing through a thin wall and striking a bystander when used indoors.

I'd recommend reading through The Box O' Truth archives (http://www.theboxotruth.com/docs/theboxotruth.htm) and Buick O' Truth (http://www.theboxotruth.com/docs/thebuickotruth.htm) if you're interested in how various rounds and calibres behave when shot at things.
