Refitted X-Boats - VW Beetles in Traveller

[navanod]

Actually, the way I built it went something like this...
Start with a 12 m diameter sphere. Then add a cone (Top Radiius=12, bottom radius=1.75, Height=16 meters).

Slice the top sphere in half. That comes out to about 450 m3.
The cone comes out to 820 m3. Put them together and you get 1270 m3, or 97 dtons The extra 3 tons can be built in widening some sections of the cone.

Total length = 22 m, tonnage = ~100 dtons, and it fits the side profile from Supp 7.

What's hard to understand about it?

A 10 meter long cone, and a 12 meter diameter sphere... neither occupying any space within the other.

Then the extra space is covered over to streamline it, and that space is used.

No, the internal bulkheads in the aft part of the sphere don't form a curved wall, but surely you can see what I am talking about?

It's not that it's hard to understand... it's that it's WRONG. Your illo fails to match the deckplans and the volume defined in the text.

The graphic below shows a 27m cone truncated to 16, and a 19.8m truncated to same, both with a 6m radius hemisphere. These are the correct shape, and the 27m is almost exactly 1400kl.... and gives a 22m overall length. The end radius is 2.44m on the 27m cone's 16m truncation, or 1.15m on the 19.8m cone's 16m truncation.



The only element which is inconsistent is the description on p.9. Any use of that description produces wrong values for tonnage; The plans are not terribly accurate, but close enough for a 27m cone truncated to 16m (which matches the plans pretty well) and the volume is close, too. Since it matches the text, the plans, the design, and doesn't match the blurb on the plans, then the blurb on the plans is wrong.

Although the truncated tail seems a bit wider that the illustration, I think Aramis's 27 meter cone truncated to 16 is the best. At least the Volume and Published Length come out closest.

I don't have the math skills or programs that some of you do.

I used the hemisphere, cylinder and cone configuration because it was the best I could do. I posted it after I had figured it out because I KNEW you guys would get me straight so I could use the true "teardrop" shape shown.

Thanks Guys.

First Cut at Deckplans

and here it is... hmmm... picture didn't post correctly, anyway its in the gallery.

Got the turret and fire control station, bridge and staterooms placed, don't think the cargo bay is gonna equal 50 tons but it does have a nice roomy corridor .

Still have to add walls/doors around bridge (guess the captain has to go thru bridge to get to his stateroom), ship's locker, clean up unwanted lines. ect

Criticize, plagiarize, ect. ect.

Gives total package J2 and M1, Please note that Service Module Cargo Capacity is HIGHER than X Boat Fuel Requirements so that it could be used as a refueler only or carried with the xboat.

There have been a lot of interesting ideas tossed around in this thread. I'd like it very much if some of you would get together and co-author an article for Freelance Traveller's Shipyard, discussing the various ideas and including properly credited worked-out examples. Deckplans and renders of the results would be a nice bonus.

 

[Patron Zero]

Anyone care to chime in on Jeff's offer to publish this thread as a proper article ?
Happy to offer my services as editor to compile and collected the supporting texts and images for this opportunity.

Would be great to present two different refits, one as the 100 ton X-hull with 100 ton service hull and the other a dedicated 200 ton hull consisting of the X-hull permanently joined to a service hull.

A given that full credit to all contributors and their works recognized.

Thanks !

 

[navanod]

Already working on some goodies from my previous work. May take some time, tho.

 

[Gray Lensman]

My schedule is all muffed up right now

 

[Deliberatus]

Therein is the basic concept of the jump-drive.

 

[snapshotbygdw]

None of the above options seem that outlandish when I think of what I've been asked to referee by a ex-navy engineer with mech-4, elec-4 and eng-4 (dam that White dwarf self made traveller article)
