ESF Wraith by wingsofwrath ESF Wraith by wingsofwrath
The European Space Force light cruiser "Wraith", an older "Witch" class vessel, does an apogee adjustment in high lunar orbit, as part of a fleet level exercise.

Concept art for one of the comic projects I'm currently working on, "Gravity", a hard sci-fi graphic novel set twenty minutes into the future...

More to come.

Great looking craft! Doesn't need to look like a big plane or a ship to be stunning :)

Thank you!
I'm of course disgruntled with the popular depictions of spaceships in popular media myself, that's why I'm trying to come up with a design that would work better in real life and still look rather "cool"...

Interesting craft design. Are those radiators, unfolding forward and aft?

It's hard not to think Chris Foss when I see a bright yellow ship :)

Yes, all the corrugated reddish brown surfaces are radiators. They are protected by whipple type shielding against kinetic impacts and by a layer of hight strength silicon carbide armour against both kinetic damage and laser ablation. They usually close a few seconds before projected impact, then reopen. During this time all the waste heat from the reactor is dumped into coolant pods (orange canisters).

Well, to tell the truth, this ship has a lot of outside influences, but mostly the work done by Rob Cunningham & J. Aaron Kambeitz for the Homeworld computer game.
Of course, I wanted the whole thing to be a lot more realistic, so my ship is modular, has the command centre located in the middle (rather than have an exposed bridge) and has no artificial gravity, save in the rotating "biopods" (the triangular prisms attached to the main body by tall pylons)

Great stuff, nice to see more people thinking of necessary but 'less cool' stuff, like heat radiation. My own designs carry quarter-circle folding sails as radiators, but of course I can't draw well enough to do them justice.
The heat dumping pods are a neat feature

In fact it's probably one of the most necessary things in space flight and also one of the most casually overlooked. Even the ship from 2001 lacked them, despite the fact they knew exactly just how important they were, but still they chose to omit them for the sake of popular perception, since they thought "wings" on a spacecraft would look weird...

It took a while to get a mental image of what you mean, but are the radiators the curved parts at the aft of your ship? [link]

I should redo the radiators on this ship though, because one thing I hadn't considered when I made the original design is the fact that if you place radiators at 90 degrees or less to each other they're going to radiate heat into each other, which of course will drop the efficiency of the whole system as a whole...

Yes I too read that they omitted the wings, but that it would have looked a bit like a dragonfly.

And no, sadly that ship you linked is a 'stereotypical' sci-fi craft I cobbled together for fun, just a bunch of bits with engines on one end.

The radiators I meant are the big quarter circles that I managed to paint a horrid red pattern here.

I'll repaint that ship at some point..

Oh, I see. In fact I think having semicircular radiators following the external curvature of the hull would in fact be more efficient, since the same problem that was pointed out about my design would be in effect - radiators set at 90 degrees to each other would radiate some of their heat into each other which would bring down the efficiency of the whole system, that's why current spacecraft radiators are always set at 180 or more degrees.

Also, coming back to my design, for the next iteration I settled on fixed heat transparent armour rather than the movable hatches I have now, since, of course, not having to close the radiators just prior to projected impact would make the whole thing more secure. The heat dumping and pods would remain though as a method to decrease the thermal signature and confuse the guidance systems of approaching enemy missiles when used din conjunction with heat emitting decoys.

Thanks for the background details. Again, a fine design :)

A bit of a work-in-progress, actually. I think I might refine some of the details further and post an updated version sometimes in the future.
