Lab Ship

Sure. I'll do you a portrait version (8.5"x11", right?)

That would be absolutely fantastic if you would, yes - but make sure I can put the magazine masthead - probably about two inches - at either top or bottom. Also, I'm planning on releasing the PDF as both ANSI-A (8.5"x11") and ISO-216 A4 (210mmx297mm), so it should be able to take that slight left/right cropping as well.

email is editor@freelancetraveller.com. I'm hoping to get the introductory issue out this weekend dated November 2009, and regular issues beginning around Christmas dated January 2010.
 
Structurally, two or three arms would be simpler, but one arm can be made to balance if the Mass is distributed correctly. Crankshafts can be balanced without being symetrical.

I like the 1 arm ... it says "this ain't no TL8 station".

It also puts asymmetrical thrust stresses on the torus, that will require more bracing on the arm-side of the torus...

a 2,3, or 4 arm design is simply better engineering.

With advanced materials and inertial compensation, I'm not sure it's a problem.

It's still an issue of load-bearing. The advanced materials simply reduce the overall size of the load-bearing system.

Inertial Compensation is irrelevant, unless it's also the drive modality.

Given that the engines are at 3 O'clock and 9 O'clock, and the connector at 6 O'clock, and the connector arm is roughly 3/4 the length of a quarter turn of the ring, the net load is 11 to 8 lower vs upper, and the drives are also above the obvious center of mass, that means the ring needs more mass for the sake of balance opposite where it needs it for strength, and by a significant factor, for dynamic balance. And that's just based upon thrust issues, not even considering spin. And spin will, due to physics, want to bring the central pod out of center, just a touch anti-spin, further warping the spin center.

Lots of dynamic load reasons to NOT use a single arm
 
Not to be too negative but it still seems too... sharp? fresh? Needs a little more noise and distraction. Greebles and what not. Maybe some markings with lighting cast on them (University of Rhylanor or some such). Know what I mean? :)

As for why just the one arm* at least in Traveller there's a good(ish) reason. Less volume. And in (most) Traveller ship building it's all about the volume. Not weight, mass, strength or any other elements.

* why an arm at all is my question, why not a simple ring with the pinnace internal to the ring somewhere

I agree, even the fuel in the tanks would want to harmonically balance the
ring, which is generally slight considering the low rpm of spin plus that the
Pinnace is outside of the area of centripital force (gotta love zero-g). Even
a simple silicon gel in the fuel tanks could act as dynamic harmonizer.
 
Can I agree with far-trader?

Andrew, if you can add a star, why not light shining from port-holes?

And far-trader is right, it needs a university marking, maybe half-shadowed by an aerial?
 
Nice work I got inspired to do my own lab type ship. It is a limited run by a small shipyard. I might get it done soon enough. Working on it.

GOOD SWEET STREPHON!!!

That's absolutely beautiful, Andrew, just breathtaking...

Thank you so much for sharing it with us...

Indeed it is, and it is also the cover of Issue 000 of Freelance Traveller Magazine - link in the separate thread.

Thank you, Andrew - it really does look fantastic!
