Shouldn't "realistic" spaceships be just a cube?

Why?
Yeah there's no need for aerodynamics once you're out of any atmosphere, but why specifically a cube?

I read that the ideal space fighter would be a sphere, with the ability to rotate it's propulsion and weapon systems to face towards any angle (probably sort of like a gyroscope)

This. I think if we give the ship enough mass, it would make it's own gravity, too. At that density, however, we would have to vacate the interior, what with all the mass and resulting heat and pressure in there. On the other hand, the ship could then be open to space as the necessary gasses would simply stick to the ship's surface.

>>59456476
>100% AI controlled
>Real Life Space Combat, it would be quick and brutal as fuck

So true I don't even want to think about it.

>>59456476
I mean space combat wouldn't be anything like this. Why waste space and resources for drone fighters when that can be filled with missiles or railguns.

Literally 0 reason for earth style combat in space. Like you can just fling rocks at ships or launch missiles which would be more effective at extreme distances than "AI controlled" drones.

>>59457316
Because if you had weapons mounted to the ship you'd need to orient the large main ship to target, if you have a small drone that has fast 360 degree movement you could position it perfectly to fire whatever weapon it has

To those of you arguing for the "strength" of shapes, you're talking fucking nonsense. You perspective is based on exposure of very small objects where the surfaces and edges are made up of few or single pieces. Yet for extreme future "space" materials all of these small scale concerns that you see in childrens toys on your carpet will be irrelevant and the important, deciding factor, of shape shall be something that we haven't even imagined yet. Perhaps we'll need best surface area to volume ratio whether that's higher or lower, so a sphere or plate shape. Perhaps propulsion or life support or power or any other unforseen mechanism requires a shape, of separating these things apart requires a shape.
Basically stop talking shit and there are such things are stupid questions.

>>59457393
The answer is yes. The picture is just so that he can get attentions.
Also, to said anime fag: you write like an anime subtitle / reddit kiddy. Your ideas are childish which is absolutely OK. But you also write in statements and assertions which is not OK because it shows ignorance to the fact that you're just a musing child. Even being a child isn't a sit, all thoughts start somewhere.
Just stop being a pussy by using your anime to get attention and learn to show some self awareness.

there are many non aerodynamic factors present in vehicle design.

If you look at most spacecraft these are apparent to some degree, though manned pure space vehicles have seldome existed without constraints of launch vehicle size and aerodynamics et cetera.

Consider the desire for rtificial gravity in a crewed vehicle. this suggests a design with some means of rotation, either an unbalanced tethered design, or something built around an axis, as with toridal structures.

many craft also have regions with a need for insulation from the rest of the craft.

Nuclear engines, for example, would need to be kept away from instruments and crews if present. Certain ideas for startships tend to include large frontal sheilds for high-velocity impacts, as well as a clear front and back. Need to drop used fuel tanks also suggests tanks need exposure, and to be situated so they can easily be discarded.

additionally, depending on power source, in many cases designs call for areas of high surface area. These can be variably solar sails, photovoltaics, or raditors. Many vehicles use at least the last two. situating these on the walls of a cube or sphere is not the most efficient design.

Making spaceships is not an easy task. By leaving the atmosphere, we eliminate many design limitations placed on conventional vehicle designers, but we find ourselves faced with many new concerns unique to the roles of these spacecraft, as well as to their unconventional envieronment of operation.

well, depends on the size of a sphere. A small enough one is probably alright. Trying to do, say an ISS scale thing (in volume and power use) would make heat dissipation a problem, but a cubesat is evidently alright.

What's with all of the stupidity here?

The biggest problem in space is heat dispersion. The only sustainable way of getting rid of heat is thermal radiation. You would need a ton of surface area even for a small ship. Pretty much 80% of your ship is going to end up being thermal radiators.

Yeah, if you have a ship that basically just floats in space and doesn't do much beside provide life support like the ISS. If you needed to move around or fire lasers like that one retard in this thread brought up, you're going to need radiators like a motherfucker.

If you wanted to destroy an enemy ship, you'd target their radiators because it's going to be a fucking huge target and once their radiators are gone the ship will either need to shut down everything except life support or commit suicide.

I guess you don't want corners in a pressurised cabin because they're weak spots.

Why not just a giant sphere?

>>59455175

Most efficient use of space would be a sphere.

BUT

Realistically you'll need to dissipate heat from the engines / weapon systems, which means huge heatsinks with radiators on the outside of the ship, away from any systems. With a sphere you have no means to store away and radiate heat so it slowly cooks everything on the inside.

Also to maneuver effectively you need leverage, i.e. thrusters as far away from the center mass as practically possible.

At the same time it would be good to have a shape that can maintain structural integrity even when damaged, AND generate its own gravity using centrifugal force.

A series of rings rotating around a central shaft would probably be the best way to go around it.

>>59457953
Tie fighters from star wars are a fairly reasonable shape. The main body is a shere to make it easy to have a pressurize cabin with large volume, and there's big ass radiators to dissipte heat.

>>59461038

You dingus, with high energy equipment like weapon systems you still need a lot of mass for the excess heat to quickly dump into, i.e. solid heatsinks. The radiators will then dissipate it into space at a much slower pace.
Radiators by themselves are too slow to get rid of the heat fast enough and would shit the bed after a couple of salvos, then the whole thing would just melt.

when the spaceship is accelerating

you can't just build a spaceship of any shape
for example imagine a space ship built like a straw where the main engines are in the middle, perpendicular to the straw shape

when the ship is accelerating, even though there is no gravity or drag, the straw will bend and might even brake because of inertia at the tips

Also a huge spaceship will come in contact with a lot of space debris (small rocks and such). An airplane or flying saucer shaped space ship would do a better job at reflecting this debris than a cube

>>59455175

This word you used ... "should." You don't seem to understand what it means or how to use it.

Space ships _SHOULD_ be designed using whatever shape accommodates it's intended use & purpose.

A cube is one possibility, but only if it's propulsion system (among other considerations) would work efficiently with that.

Until we understand much more fully how we will design a ship that balances life support, propulsion, stress on construction materials, shielding from hostile environment, etc. etc., we really have no idea what shape a space ship will take.

all the nuclear powerplants are laughing right now

well except chernobyl

>Makes no sense to shape a spaceship after them
It makes perfect sense. Same forces will be applied on spaceships.

>>59461822
But it does makes sense. A spherical shape has better resistance against superficial tension, but maybe a cylindrical shape is more practical, as its possible to emulate gravity.

>>59461853
so you are implying that the gravity acts on the entire universe at once ?
cause this is the only feasable scenario of your idea to work
spaceships wont spend their life in orbit of a start to even get such a high level of stress..

>>59461908
I hope you didn't intended what you said to me...

LMAO... where did I state that?

To play the same retarded game, let me ask you this: Are you stating that force of gravity doesn't act of spaceships?

>cause this is the only feasable scenario of your idea to work
kek'd.

>spaceships wont spend their life in orbit of a start to even get such a high level of stress..
Then the sphere males EVEN MORE sense.

>>59461956
when you state that the same forces will apply to the spaceships
you are either saying that the spaceships will actually remain all of the time under the infuence of a massive gravitional pull
or that whereever they go they will encounter gravity at any level which we already know it doesnt happen

bitch please

Yes, the heat from everything you listed is continually escaping into the environment.

>all the nuclear powerplants are laughing right now

Please explain the purpose of a cooling tower to me.

What >>59461548 said was
>the radiators obviously will be a thing in the past since the heat can be used for literally many things around the ship

Which is fucking retarded because if you keep adding heat to a very well insulated system (which a spacecraft without any means to radiate heat effectively definitely is), then you can have all the exchangers you want inside and they will all eventually become useless because you can't make the hot side of an exchanger hotter indefinitely without the cold side of it getting hotter as well.

>dissipating cold

...or you know what, just kill yourself.

half of the ship will hit the sun the rest will drift off

i'd go with ring, torus, or cylinder

>>59461194
its not just infared, you could get it so hot that it glows in Xray, it ddoesnt matter, the point is radiation is probably the way to go, after conducting to heatsyncs.

There is also a style of radiator that pumps liquid droplets of radiator fluid out and uses them to dissipate heat from the vehicle, sometimes recovering the material. You could also potentially channel some heat to other uses, say, hot gas jets.

But for most purposes, you need a good, stable means of dropping heat off, especially out of the vehivle. Heatsyncs just hold it for a while, but a big lump of steel isnt good at radiatong due to surface.

>>59457953
The one issue I see is that radiators facing other radiators isnt going to be a good idea.

>>59462196
but in many cases, there will be other parts. There is no reson to put a nuclear power plant on the roataing section, radiators add more complexity.

Only one small part should be torridal or cylindrical.

I note that most oneill things were not spaceships but stationary, erm, stations. They didnt have engines, well, not big ones anyway>>59462081
(who create a lot of heat potentially) or fuel tanks, or other things.

>>59462081
I doubt it could turn that fast unless it was under great duress, say, swinging past a blackhole.

>>59455337
Using a manned spaceship for space warfare is the stupidest thing sci-fi authors ever imagined.
Using drones would be better in every way.

>>59455432
that was such a lovely book

>>59456858
to keep a pressure of 1 atm in the ship you would need a ship the mass of 1 earth

Rocket ship that detaches on the top holding the cube in the middle with a wire structure of wings on the side and the bottom rocket part detaches

>>59455209
makes sense, also a sphere has best volume to surface ratio, would be good for solar an shit.

It was a combination of factors. Cracks started with the riveted seams, got worse due to square windows.

Abrupt failure probably wouldn't have happened with round windows even with the shitty joining.
